leia sounds like leica although the corporation name was adapted from the star wars princess leia. red announced a partnership with leia as a provider of the light field holographic display. this clears the red view of vr, ar, & mr. leia and red seem to have established mixed reality into hydrogen. changing the angle from present to future .
leia inc is a silicon valley startup company developing an interactive holographic display for mobile devices. [ 1 ] leia is also developing software tools to facilitate the creation of content for its holographic platform. besides its use for mobile applications (wearables, internet of things (iot); smartphones, tablets), leia’s technology is also aimed at the automotive and medical markets. [ 2 ]
red digital cinema and leia inc. have come together to create a richer way to interact with the people and things you love. effortlessly dive into a world of new depth and proportions. available on red hydrogen™ .
well, now we have an answer: red’s screen technology comes from an exclusive partnership with a startup called leia inc. (yes, like the princess .) leia describes itself as “the leading provider of lightfield holographic display solutions for mobile, ” and was founded in 2014 as a spin - off from hp’s research labs. red has made an undisclosed strategic investment in leia as part of the partnership .

david fattal, founder and ceo of leia inc, was named french innovator of the year by the mit technology review in 2013 for the invention of the multiview backlight, and was featured on their global list of 35 innovators under 35 the same year. [ 10 ]
may the force be with you … the princess leia hologram in star wars. similar technology could soon be available on smartphones
leia inc has released a web - based development environment (ide) and an api to guide the creation of holographic content for any multiview 3d display platform, including its own display. it currently supports webgl via three. js, and a unity plug - in is on its way .
leia’s core multiview backlight concept was featured on the cover of nature in the march 21st 2013 issue. [ 7 ] [ 11 ]
fattal claims that leia’s diffraction - based system is much more efficient than traditional parallax barriers and lenticular designs for multiple position glasses - free 3d. he says it is also much easier on the cpu than the eye - tracking approach amazon is rumored to be using for its planned smartphone. one other advantage leia’s technology has over the eye - tracking approach is that leia’s displays can be viewed by several people at once. leia has also already coupled one of its prototypes with a leap motion sensor, allowing the creation of interactive applications .
leia says that its ttechnology does not impact battery life. while the focus is the holographic display for media and games, leia says the screen also has other uses, like creating “privacy viewing zones, ” which would presumably make the screen only viewable from a certain angle .
and pierre evreux, leia inc is a technology spin - off from hewlett - packard laboratories developing a lightfield display technology platform for naked - eye holographic and virtual reality applications. it focuses today on the mobile and automotive markets, with first devices expected in the hands of consumer by the end of 2017. the company is based in
while leia’s holographs won’t be projected like the hologram of leia in star wars, they will offer a true sense of depth and be viewable from up to 64 different angles without any special glasses. a 3d movie, on the other hand, can only be seen from one angle .
at the very least, this doesn’t sound like it will be quite as gimmicky as the holographic screen on amazon’s fire phone, which offered very little in the way of ‘wow’ factor. but it’s still going to be a niche product – unless you happen to be receiving an intergalactic sos from the namesake of leia inc. ’s brand .
scientists have created a glasses - free, 3d display that could mimic the famous hologram projection of princess leia in the original 1977 star wars film .
) - - red digital cinema, the leading manufacturer of professional digital cinema cameras, and leia inc, the leading provider of lightfield holographic display solutions for mobile, announced today a long - term exclusive partnership to bring the world’s first lightfield “holographic” smartphone - - the hydrogen one - - into the hands of consumers in the first half of 2018 .
, leia inc.' s founder and ceo .
this is a brand new technique that produces multi - view 3d – holographic – content with an unprecedented level of quality and visual comfort for several viewers at a time. moreover, the displays are entirely switchable to standard 2d viewing mode so there is virtually no downside in using them .
the new york stock exchange welcomes brightview holdings, inc. (nyse: bv) in celebration of its ipo. ceo andrew masterman, joined by nyse president stacey cunningham, rings the opening bell ® .
leia’s display technology relies on a technological breakthrough—a multiview backlight —developed by the core leia team during their tenure at hp labs in palo alto. [ 5 ] the team had been working on an early laser - based version in 2011 before transitioning to a more standard led - based illumination system in 2012. [ 6 ]
leia inc. is a spin - off from hp labs which aims at commercializing a disruptive display technology, a diffractive backlit lcd system allowing the rendering of holographic 3d content at video rate on a mobile platform. leia’s core technology resides in the surface treatment of the backlight, and otherwise utilizes a commercially available lcd panel to create animated content. it uses standard led illumination, comes in an ultra - thin form factor, is capable of high pixel densities and large field of view and does not consume more optical power than a regular lcd screen .
when red camera first announced its crazy $ 1, 200 hydrogen smartphone with a
holographic display ,
a lot of folks wondered how that would actually work. now, ceo jim jannard has revealed that red is creating the screen in partnership with a company called leia inc. (yes, like that leia). a spin - off from hewlett - packard labs, it calls itself
the leading provider of light field holographic display solutions for mobile ,
and the key words
light field
gives us a pretty good idea as to how it works
the only downside to leia is that its images have to be viewed within a 60 - degree arc of the display. go beyond that and the hologram looks flat .
leia uses nano - photonics to create a holographic screen that preserves the usual smartphone touchscreen functions and also does not create extra bulk. according to leia’s website, its technology uses diffractive light field backlighting, using nanostructures to give a screen “almost magical” properties — or creating small 3d projections from the screen. a demonstration from 2015 illustrates the idea :
ever since r2 - d2 beamed out a tiny hologram of princess leia in star wars, 3d projection has been a pop culture mainstay and the dream of many a techie .
cinematic camera maker red has a smartphone on the way – the hydrogen, which boasts a great video camera as well as a “holographic display” that we know relatively little about, despite mkbhd getting some hands - on time with the phone ahead of its release. now, we know more because red ceo jim jannard named hp labs spin - out leia inc. as the display tech partner (via engadget) .
but not just any image can be seen as a hologram. leia actually takes 64 photos of a single object viewed at a slightly different angle and combines them into one picture .
leia is a technology spin - off of hp labs and a provider of the leading holographic display solution for mobile. the leia 3d display provides a comfortable, natural form of 3d that is easier to look at, which is important for the in - car experience. it also gives designers and developers a new tool for building a more appealing user experience .
founded in 2014 by david fattal, zhen peng and pierre - emmanuel evreux, leia inc is a technology spin - off from hewlett - packard laboratories developing a lightfield display technology platform for mobile devices. through nanotechnology and software innovation, the company empowers device manufacturers and content providers in various industries to create the next digital experience for consumer. the company is based in menlo park, ca with operations in suzhou, china .
to impress the show' s retailers, real - estate developers, and investors, brookfield and its designers, lorenc + yoo design and journey communications inc. , felt they should mirror the company' s uber - chic new york headquarters .
despite already listing for a $ 1, 200 - plus pre - order, red has shared very few specifics about the company’s first smartphone, the hydrogen one, which comes with a holographic media display. but a new business partnership is shedding light on what, exactly, that “holographic media display” entails. on thursday, red digital cinema announced a partnership with leia inc. , a 2014 startup focusing on light field displays .
new tech start - up leia creates 3d holographic displays. multiple leds are projected across a thin piece of plastic or glass, forming an image that appears to float above the screen .
leia’s technology works using light field technology, which stacks lcds with backlights pointing in different directions. when you combine the angles of the backlight projecting the images on screen, you can produce 3d effects visible by the naked eye. leia’s innovation is making this work while also keeping the traditional 2d display capabilities undisturbed, so that you can switch between both modes depending on what you’re viewing .
key to leia’s technology is the use of fairly simple diffraction gratings at each pixel to redirect the backlight in different directions. the gratings are created by etching grooves in a thin sheet of glass. placed under a conventional lcd, the gratings create as many as 64 different points of view — in an eight - by - eight grid. because it uses only diffraction, leia’s system can calculate the needed light field in real time — much faster than more complex interference - based hologram generators. to complement the gratings, leia has created a specialized, programmable led backlight that it also manufactures .

leia’s technology, however, replaces the light - guiding panel with its own panel, which directs light in very precise directions. it’s this ability to direct light in such an exact way that creates the holographic effect .
hen you own posh properties like the world financial center in new york and the bank of america plaza in los angeles, your exhibit can' t look like a strip mall. that was the challenge facing brookfield office properties inc. for the 2011 recon expo produced by the international council of shopping centers .
in its current state, the display developed by leia inc is a diffraction based system able to project 64 different images in different directions of space. the diffractive layer extracts led light from a light guide and forms narrow light beams that propagate towards the viewers. the intensity of each light beam is independently modulated by a dedicated pixel on a front - facing lcd panel. color can be achieved either via spatial - multiplexing (rgb color filters on dedicated lcd subpixels) or via temporal - multiplexing (time - sequential rgb illumination). [ 8 ]
“we are thrilled to partner with jim and the red team on the hydrogen program, ” says david fattal, leia founder and ceo. “they have a bold vision and share our urge to disrupt the mobile industry with true innovation. ”
“this is an incredible opportunity for both companies and a perfect marriage, ” jannard said in a statement. “leia brings a very special piece of technology that blends seamlessly with our vision of a ground - breaking and disruptive consumer product. ”
the technology works through diffraction, producing a lightfield illumination with a layer of nanostructures added to a conventional lcd. leia claims this “diffractive lightfield backlighting” layer doesn’t significantly compromise the display’s quality, battery consumption, or thickness for non - holographic use .
leia s - 95 is a smaller tv like display perfect for presenting objects, 3d models, games, creating virtual assistant or control panel. excellent choice for trade shows, museums, promotional displays. our proprietary software makes display fully interactive .
in addition to use in mobile computing, fattal sees applications for leia’s technology in medicine, home automation, and car infotainment systems. the company is already actively courting developers, with a programming toolkit that allows simple conversion of webgl objects into leia - displayable ones with only a small amount of additional code. the company is still working closely with hp, and in fact has its factory co - located there, but it is ramping up its production operation in suzhou, china. if fattal is right that mobile display manufacturers have resolution to burn in their upcoming product cycles — and leia can solve the problem of driving its display in full color at standard video frame rates — then look to see holochat coming to mobile devices in the near future .
silicon valley - based company leia (yes, like the princess) is developing a technology that gives any lcd display the ability to generate 3d holographic images. it showed off a public prototype of its screens for the first time at mobile world congress .
“this is an incredible opportunity for both companies and a perfect marriage, ” says jim jannard, founder and chairman of red. “leia brings a very special piece of technology that blends seamlessly with our vision of a ground - breaking and disruptive consumer product. ”

when he realized that the same technology could be used to create 3d holograms, fattal left hp, bought back the patents from the company, and founded leia with his longtime friend and former wall street investor, pierre - emmanuel evreux, and fellow hp alum, zhen peng .
red has formed a
strategic partnership
with leia and made an unnamed investment in the company, and jannard will join its board of directors. it says the smartphone will arrive in the first half of 2018, and functional prototypes are supposed to be ready in the coming months .
leia leverages recent breakthroughs in nano - photonic design and manufacturing to provide a complete lightfield “holographic” display solution for mobile devices, through proprietary hardware and software. the silicon valley firm commercializes lcd - based mobile screens able to synthesize lightfield holographic content while preserving the normal operation of the display .
together, honda xcelerator and leia have developed a new 3d driver display demonstration that leverages nanotechnology to provide seamless transitions between different viewing angles for warnings and driver - assistive systems. vocalzoom has been working with honda xcelerator to apply its optical microphone technology to improve voice interaction inside the vehicle .
as it stands, leia is still in its early stages, although the company says it will have a developer kit available for testing by the end of this year. that means big - name companies like apple and samsung could soon begin working on smartphones and tablets with 3d hologram capabilities .
kyocera document solutions inc. headquartered in osaka, japan is a leading manufacturer of document imaging solutions and document management systems, including color and monochrome multifunction printers and printers and wide format devices. kyocera' s products are renowned for their unique long - life imaging components that provide greater reliability, less waste - resulting in a lower total cost of ownership (tco) over the life of the product .
since the output of its display is 64 different points of view, leia has been able to build a matching input device using an array of 64 mobile cameras in a simple 3d printed frame. the combination may become the world’s first mobile holochat device. each camera maps directly to one of the 64 sets of pixels in the display, so very little image processing is needed in between. that allows leia to create realtime interactive 3d displays, like the one fattal is explaining in the accompanying photo — where a moving hand is mapped instantly into 64 different views that can be sent to one of its displays .
in principle you would be able to move your head around the display, rotate your head in any direction, and still see a 3d image, much like what you see in star wars, with the famous hologram of princess leia ,
said david fattal, who helped to create the device .
fattal hasn’t said what companies are interested in the technology, but based on how well it works, and how easy it would be for a company to implement in its existing products, we wouldn’t be surprised if the biggest names in tech are looking at leia with some interest, from many different angles .
combining high - gloss black laminates, carrera marble, eames chairs, and leather furnishings, brookfield office properties inc.' s exhibit seemed more like a private salon than a stand. while the booth' s exterior walls' black and white hues lent it an air of cosmopolitan chic, the interior' s plush banquettes and soft linen - padded walls made it as sumptuous - and comfortable - as a spa .
although 3d can be distracting if it isn' t designed correctly, leia' s nanotech approach presents depth in a way that feels natural. as a result, when the driver moves his or her head while looking at the screen, the content changes aspect continuously and allows for multi - view 3d imagery .
the strategic partnership will leverage red’s expertise in digital content creation and deep connections in the film industry as well as leia’s proprietary lightfield display technology and software platform to disrupt the world of mobile entertainment. the hydrogen program will feature stunning holographic content and 3d sound for movie viewing, interactive gaming, social messaging and mixed reality .
when pushed through leia’s panel, though, the light from each photo is directed in such a way that each image appears next to each other in a specific order. so instead of having 64 shots of the empire state building on top of each other, you have a perfect 3d 360 - degree image of the tower .
david is the founder and ceo of leia inc, a spin - off from hp labs aiming at commercializing a novel holographic display technology for mobile devices. he previously spent 9 years as a senior researcher in the intelligent infrastructure laboratory at hp labs, working on various aspects of quantum computing and photonics, and specializing in the manipulation of light at the nanoscale. he holds a phd in physics from stanford university and a bs in theoretical physics from ecole polytechnique, france. david received the 2010 pierre faurre award for young french industrial career achievement, and was named french innovator of the year 2013 by the mit technology review before featuring on the global innovator list that same year. david has 60 granted patents and co - authored the text - book “single photon devices and applications” .
until now, the problem for diffraction - based solutions has been resolution. since each pixel needs to be projected in 64 different ways, the display resolution is reduced by an equivalent amount. with lcd makers racing past 500 ppi in mobile displays, leia is betting that some of that additional resolution can easily be sacrificed for the added value of an interactive 3d display. leia also needs to address color. early prototypes have all been monochrome, although fattal says the company has been prototyping both time - sliced color displays — using very high refresh rates to alternate between colors — and spatially - divided displays, which would of course complicate matters by further reducing resolution in exchange for adding color .
this unique technology makes possible to walk through the image, touch it or interact with it. streams of barely visible fog becomes an image carrier and their laminar structure allows to display high resolution contents. our patented way to produce laminar airflow for very long distance from the output makes leia display the most steady mid - air screen on the market .
leia display achieves a wide 3d field of view of 60 degrees [ 3 ] and offers full parallax to create a seamless 3d impression regardless of head motion (horizontal / vertical motion, tilt or rotation). the diffracted beam parameters can be adjusted to suppress “jumps” or “dark zones” between views and repeating images outside the field of view.

the idea is that the screen projects 3d objects that you can view from different angles based on your physical position. for example, a mapping application could theoretically look like a little model of a city with buildings poking out of the screen. you’d then be able to interact with the objects “above” the display through hover gestures enabled by leia’s partnership with synaptics .
the partnership, which is both exclusive and long - term, will mix red’s digital content expertise and leia’s light field display tech, according to a press release. that agreement is part of the hydrogen one, which the companies say will include both holographic content and 3d sound for viewing movies and media, gaming, mixed reality, and even social media .

eeoc initially filed suit against global horizons and two yakima, wash. , farms in april 2011, charging a pattern or practice of national origin and race discrimination, harassment, constructive discharge and retaliation against the thai farmworkers, in violation of title vii of the civil rights act of 1964 [ eeoc v. global horizons, inc. , et al. , case no. 2: 13 - cv - 03045 - efs, in u. s. district court for the eastern district of washington ] .
now that the dick tracy wristwatch is nearing reality, is it time for holographic star wars - style messaging to make its debut? hp labs spinout leia believes it is. using a clever system of diffraction gratings, its small displays produce 64 different versions of each image, allowing a viewer to move around an object or person shown on the display as if it was right in the room with them. ceo david fattal spoke to an eager crowd of imaging researchers at stanford university about his company’s progress since it separated from hp. while the concepts behind leia are the same as when the team’s work at hp was first published in nature last year, the new company now has full color prototypes with improved resolution as it prepares for a product launch .
this would mean you would see something like in' star wars,' with the famous hologram of princess leia ,
study researcher david fattal, of hp, told new scientist .
if you were to display a 3d image of planet earth, by turning around the display, you' d be able to have a view of any country on the globe .
even if the tech works great, though — and that’s a big if — red and leia will need to have a credible array of content lined up for the hydrogen one if the screen is to be anything more than a gimmick. “the hydrogen program will feature stunning holographic content and 3d sound for movie viewing, interactive gaming, social messaging and mixed reality, ” according to red’s statement today, but it’s not clear where any of that is going to come from .
los angeles - a federal judge has ordered farm labor contractor global horizons, inc. to pay $ 7, 658, 500 for a pattern or practice of subjecting thai farmworkers in the state of washington to a hostile work environment, harassment and discrimination in violation of federal anti - discrimination laws, the u. s. equal employment opportunity commission (eeoc) announced today. senior u. s. district court judge edward f. shea found that global' s discriminatory practices were
reprehensible
and vindicated the thai farmworkers who suffered from
fear, anxiety, anger, intimidation, humiliation, shame, and an unrelenting sense of imprisonment .
holography, the gold standard for 3d display, reconstructs the light that bounces off an object at every angle 1. a hologram uses a complicated pattern on a plane so that light passing through it diffracts and interferes to produce a life - like image. but, so far, moving holograms — like the ethereal video of princess leia in star wars (george lucas, 1977) — remain in the realm of science fiction. this is because it takes much too long to calculate and produce these shifting patterns for any viewing angle .

how well does this work in practice? very few people know for sure. one is youtuber and noted red shooter marques brownlee, who checked out a few hydrogen one prototypes last month. brownlee, better known as mkbhd, said he was “pretty impressed” by the display, but that it “definitely wasn’t perfect” with some stuttering and light bleed issues. you can get an idea of what he' s talking about in the video below of a leia display prototype demonstrated in may (without the benefit of seeing it in 3d, of course) :
leia says it
leverages recent breakthroughs in nano - photonic design and manufacturing to provide a complete lightfield' holographic' display solution for mobile devices .
it says the tech can create a holograph - like effect ,
while preserving the normal operation of the display .
in other words, if you turn off the 4d part, it' ll work like a regular smartphone screen. red hasn' t showed the tech to many folks yet, but mkbhd' s marcus brownlee did see it, and said he was
pretty impressed ,
adding that it wasn' t perfect because of issues like light bleeding and stuttering for 4d gaming .
since the appearance of the princess leia holographic message in the 1970' s star war movie, researchers have been exploring the feasibility of producing a real world prototype. recently, similar excitement has been stirred up in the community with the “three dimensional (3 - d) forensic chamber” in the television series “bones”. the closest systems that have been built so far are the cheoptic - 360 and the holography - 360, which allows a two dimensional (2 - d) object scene to be floated in mid - air and observed by viewers from the four sides. however, it is simply the projection of a 2 - d planar image, and there is no depth or disparity information as in the original object scene. to create the 3 - d illusion, the scene (or the object (s) in the scene) on each side is / are rotated continuously .

the mobile computing industry is experiencing a booming development fueled by a growing worldwide demand for smartphones, tablets (and soon wearables), the availability of low - power system - on - a - chip (socs), and a well established supply chain in asia. remarkably, there is enough graphical processing power on the latest smartphones to manipulate and render multiview 3d “holographic” content on the fly. if only we had the technology to project this holographic content from a portable screen…
in this talk, i will present some fundamental aspects of the technology and will discuss various consumer applications .
auto - suggest helps you quickly narrow down your search results by suggesting possible matches as you type .
during the summer of 2011, after years of working on the problems of optical interconnect and coupling light in and out of photonics chips, it occurred to our team that similar technology could be used to create a controlled lightfield. a few weeks later we had our first prototype, a floating letter “x” over a letter “o”: we had created a 3d image that we could experience without wearing the dorky red and blue glasses. we knew we were on to something. (in fact, you might have read about the project on this blog, back in june 2012: glasses - free 3d display - a new invention from hp labs )
in research released today in nature magazine, we’re excited to introduce a multi - directional diffractive backlight technology allowing the rendering of high resolution, full parallax 3d images in a zone up to 180° and up to one meter away .
until now, existing commercial 3d solutions have been geared toward large viewing distances and narrow viewing zones, as opposed to the short - range viewing of mobile devices. a mobile screen requires high pixel densities due to the short viewing distance, and a wide view angle in order to accommodate large head movements or tilts. given consumers’ increased reliance on mobile devices for content consumption, our research goals around 3d display technology have targeted mobile applications from the very beginning, looking to develop a mobile 3d display technology that is power efficient and offers a good image quality at a close distance .
our display technology forms 3d images by projecting different 2d images into different regions of space. a viewer located near the display will see a different image from his right and left eye, resulting in a 3d effect without the need for special glasses or eye tracking. as the viewer moves around (or tilts) the display, he or she will perceive a succession of different image stereo pairs, creating the illusion of continuous motion parallax .
the key to our design is a led - based guided - wave illumination technique that produces wide - angle multi - view images in color from a thin planar transparent lightguide. pixels associated with different views or colors are spatially multiplexed and can be independently addressed and modulated at video rate using an external shutter plane .
we’re excited about where this technology can take us in the not - so - distant future. beyond the obvious realms of gaming and entertainment for consumers, we see a number of important enterprise applications, including 3d maps, medical telepresence, interactive models for construction, design and architecture industries, among many others. and above all, we’re excited to help make all of these a reality without the dorky glasses .
impressive key patent for your future! this technique could allow to combine photogrammetric restitution, cloudworks and any 3d treatments to be usable thru teleworking for (hope) an affordable price .
@ baudouin: we use standard leds to illuminate the display so we do not expect any hazard. we have not tested the display with respec to eye fatigue yet .
@ rebel: yes your phone can render 2 - view 3d images, where your perceive depth if you look at the screen from the right direction. notice however that when you tilt or rotate the screen, the 3d effect disappears. the technology we have developped renders 64 - view 3d images that give you the correct perspective of displayed content when you tilt / rotate the screen, allowing you to
see behind objects
.
@ casualobserver: same comment, your game console can render 2 views creating the impression of depth when you look at the display straight on, but the perspective of objects does not adjust as you tilt / rotate the display .

glasses - free three - dimensional (3d) displays could revolutionize areas such as data visualization, medical training and entertainment, particularly if adapted to mobile devices. holography can provide ideal 3d viewing but is too slow or expensive for many applications. multiview approaches are the alternative, exploiting various geometric optical tricks to create 3d images that can be viewed from many directions at the same time. a team working at hewlett - packard' s laboratories in palo alto has developed a new multiview 3d display that is particularly well suited to mobile devices, which require thin displays with high spatial resolution and a wide - angle view zone. central to the new device is a set of directional grating pixels, associated with different views and colours, etched on the backlight surface. the display uses an led - lit backlight very similar to those in use in lcd screens today, and is demonstrated in action in transparent hand - held prototypes showing animated sequences of up to six different 200 - view images at a resolution of 127 pixels per inch .

the display is small and light enough to work on mobile phones, and produces images that appear in 3d even when viewed from different angles, the scientists said .
to make the device, researchers at hewlett - packard labs in palo alto, california, built a transparent screen with tiny light emitting diodes (leds) around the edges. light rays sent towards the centre encounter pixels that steer the light out of the screen in different directions .
through careful control of the light, the device sends slightly different images to each eye, which are combined in the brain into a 3d object .
a prototype of the device, described in the journal nature, can send light in 14 different directions, which is too few to give a smooth 3d effect. for that, the researchers are developing a more sophisticated device that sends light out in 64 different directions .
if you were to display a 3d image of planet earth with the north pole facing out of the screen, by turning your head around the display you' d be able to have a view of any country on the globe ,
he added .
another hp researcher, raymond beausoleil, said the technology might first be used for low - cost 3d signs .
perhaps in the not so distant future, it could make its way to smartphones, smart watches and tablets ,
he added .
in an accompanying article, neil dodgson, professor of graphics and imaging at cambridge university' s computer laboratory, said major challenges must be overcome before hologram - like displays are a reality on mobile devices. key among these are whether the 3d effect comes at the expense of resolution and image quality .
the examples given in the paper show that there is considerable work to be done to improve the quality to an acceptable level ,
he wrote .
perfecting the displays and their manufacture could take a long time, dodgson warns .
i am reminded of the nine - year development of texas instruments' digital micro - mirror device, now widely used in digital projectors, between the invention in 1987 and the first commercial product in 1996 ,

optical trickery lets a modified lcd produce hologram - like still images and videos .
multiview 3 - d displays will be used to produce radically different computer interfaces and new kinds of entertainment .
a new kind of three - dimensional display developed at hp labs plays hologram - like videos without the need for any moving parts or glasses. videos displayed on the hp system hover above the screen, and viewers can walk around them and experience an image or video from as many 200 different viewpoints—like walking around a real object .
researchers from hp labs used their new display to produce an image of the company’s logo .
the screen is made by modifying a conventional liquid - crystal display (lcd), the same kind of display found in most phones, laptops, tablets, and televisions. researchers hope these 3 - d systems will enable new kinds of user interfaces for portable electronics, gaming, and data visualization. the work, carried out at hp labs in palo alto, california, relies on complex physics to make 3 - d displays that are as thin as half a millimeter .
conventional 3 - d—the type found in movie theaters—provides the viewer with only one perspective. the key to making a multiview 3 - d display is reproducing all the light rays reflecting off an object from every angle and to get a different image to the left and right eye of the viewer. some systems for producing multiview 3 - d images require rapidly spinning mirrors; others use systems of lasers and multiple graphics processors .
the hp display uses nanopatterned grooves, which hp researcher david fattal, who led the work, calls “directional pixels, ” to send light off in different directions. this requires no new moving parts, and the patterns are built into an existing display component, the backlight .
a conventional lcd uses a sheet of plastic or glass that’s covered in bumps that scatter white light and direct it through the display’s color filters, polarizers, and shutters to the viewer. the new 3 - d display builds on optics research demonstrating how the path, color, and other properties of light can be manipulated by passing it through materials patterned at the nanoscale .
the hp display replaces the randomly scattering bumps in a normal lcd with deliberately patterned grooves. each “directional pixel” has three sets of grooves that direct red, green, and blue light in one particular direction. the number of directional pixels determines the number of viewpoints the display can produce. light from the pixels then passes through a conventional array of liquid crystal shutters that pass or block the light to make a moving image—just like in a conventional lcd.
