autostereoscopic display screens brands
In addition, the next generation of 3D technology with improved features is already in the development pipeline. 3D Global products are state-of-the-art autostereoscopic 3D displays that provide a unique, direct experience of true 3D viewing or mixed 2D/3D viewing without glasses or other devices.
Autostereoscopy enables lifelike 3D experiences on monitors and PC displays glasses-free 3D. The new 3D technology is a topic that is becoming increasingly serious, both for TV as well as in the field of game consoles and has already moved almost to the centre of their attention for many manufacturers.
Let’s start from scratch: The three-dimensional perception is based on the principle that the right and left eye view an object from a slightly different angle. The two slightly different images are then automatically reassembled in the brain to form a single image, which, with the help of the different viewing angles, becomes an autostereoscopic 3D image. The three-dimensional perception that arises from this not only allows the width and height of the object to be seen on displays, but also its depth in space.
Autostereoscopic displays (3D display) allows you to get an impression of depth when watching movies or playing games, provided both eyes work together. What is new with this technique is that 3D glasses are no longer necessary.
There are different techniques that enable three-dimensional viewing on a 3D display. One technique works with parallax barriers. These are aperture grille, whereby the light of individual pixels is shaded differently from different directions in front of the screen. In this way, the right and left eyes each obtain a different image. This image is three dimensionally merged in the brain. In the end, the display itself creates the three dimensionally effect, so that glasses are no longer necessary.
Another technique is the lenticular lens system, which works with a lenticular grid. In this method, the surface of the display is manipulated with tiny structures in such a way that a lenticular grid is created, and the eyes see different images. The term “lenticular” stands for lenticular lens. These are tiny optical lenses or prisms that create a three-dimensional impression.
It will be a while before 3D has established itself in the gaming market and auto-stereoscopic screens can really stir up the market. Manufacturers of auto-stereoscopic monitors are already preparing specifically for this time.
There are already 3D tablets with autostereoscopic displaya that can be used with glasses free 3D. For example, the Android tablet “No Glasses 3D Tablet” or the smartphone Sharp Aquos Phone SH80F work with a parallax barrier to achieve the 3D impression. Gadmei or HP already have tablets with a 3D display. Of course, we also offer 3D tablets in our Standard Series, which work with glasses-free 3D on a 3D display.
Until recently, autostereoscopic technology was only used on smaller devices such as smartphones or game consoles. Since 2010, the development in the area of 3D cinema and 3D television has taken a rapid progress. 3D TVs are already finding their way into the living room, almost every current TV supports the new standard of an autostereoscopic display, but all of these devices still require 3D glasses.
In 2012, the Toshiba 55ZL2 was the world’s first consumer 3D television, which made autostereoscopic 3D images possible without visual aids for end users. This works with lenticular lenses. A camera in the TV finds out where the light is being sent by detecting the viewer’s head position.
However, autostereoscopic televisions today still do not deliver the same quality as models that require 3D glasses. Another problem is that inexperienced viewers may experience problems with watching glasses-free 3D on autostereoscopic displays. The lens of the eye is focused by the brain not on the perceived depth of the object, but on the distance of the display. This can cause eye and headaches for some people.
James Cameron’s new film “Avatar 2”, scheduled for release at the end of 2020, also uses autostereoscopic 3D technology. This works thanks to laser-based autostereoscopic technology, without 3D glasses. James Cameron’s production company has extended its cooperation with the laser projector manufacturer for five years.
Autostereoscopic images are also used in online shops for advertising purposes and product configuration. Through a 3D visualization, the product can be made more perceptible to the customer and can be tailored exactly to the needs of the user.
The exact and individual parameters of a product, such as a trouser measurements, can be displayed very precisely with the 3D configurator. The focus can be placed on a specific parameter of the product, the customer can try it out at will and determine the best choice for him personally.
With 3D media you can literally make images float. No matter whether it is an analog hologram poster or a digital moving image (3D screens), the advertising message can fly up to one metre towards the viewer, which naturally makes a powerful impression and is guaranteed to remain in the memory.
The fascinating 3D effect works completely without glasses on a 3D display, and the retention time is naturally correspondingly long. The autostereoscopic display allows a great depth of space and an amazing visual experience.
The advertising industry is enthusiastic about the new technology of autosterescopic displays because of the high level of attention that the posters can generate. Fraunhofer HHI is also already researching 3D techniques for various applications. Anyone who uses autostereoscopy and an autostereoscopic screen today will certainly be one step ahead in the future. You can also test our professional 3D viewers and 3D configurators for online shops, e-commerce or product presentations on the company website, with which virtual changing rooms are also possible.
An autostereoscopic display system is an innovative and fascinating POS solution, because it can create an intense experience for the viewer without them having to use aids, such as 3D glasses, to enjoy the 3D effects. Viewing moving 3D images without glasses means companies can create good advertising and marketing opportunities at key points of sale with plenty of customer traffic.
Autostereoscopic 3D technology takes great viewing experiences to a whole new level, because the 3D experience is even more intense, because people can move freely in all directions and it delivers the ultimate 3D viewing experience that is sure to be remembered for a long time.
Autostereoscopic displays can be used to achieve a three-dimensional image without glasses and with a variety of techniques. One of these techniques uses optical tricks to bring the light waves of the monitor directly into the eyes of the viewer. If the viewer’s head is in a certain area in front of the screen, in the so-called stereo zone, then the image appears in 3D without their head looking straight ahead.
Autostereoscopic 3D technology is ideal for advertising spaces in shopping centres, stadiums, airports, transport hubs, display windows, exhibitions and other important locations with lots of customers or visitors.
An autostereoscopic display system at the point of sale can be used for various applications because the 3D effect can be viewed from different angles and customers can move freely in front of the display. This, for example, allows you to impress by explaining the benefits of a product with an interactive 3D presentation and to captivate viewers in front of the screen with moving images. This, of course, also has a positive effect on the length of stay. It provides an opportunity to present the advertising message as a memorable highlight that the viewer will remember for a long time.
Autostereoscopic 3D is a good digital signage solution for companies that want to implement their brand strategy with impressive 3D visualisations. A unique solution that is sure to win over customers and offers a wide range of advertising options and advertising strategy ideas.
A 3D autostereoscopic display is a genuine eyecatcher at the POS, almost as real as reality, making the viewer stop in front of the screen. Another advantage is that content can be changed quickly and easily without having to spend time dismantling displays. Autostereoscopic 3D displays are a very innovative and exciting medium, the first to display moving 3D images on a screen without the need for 3D glasses.
I nostri schermi 3D possono essere visibili senza l’utilizzo di occhiali specifici grazie al nuovissimo display autostereoscopico da 21,5”, 46″ o 82” in grado di offrire una risoluzione Ultra HD sia in 2D che in 3D.
Our 3D screens can be viewed without the use of specific glasses thanks to the brand-new 21.5″, 46″ or 82″ autostereoscopic display capable of offering Ultra HD resolution in both 2D and 3D.
Furthermore, the hardware within the monitor means they are able to manipulate the pixels in such a way that the 2D source is displayed in 3D through the monitor itself, without the need for glasses.
The content for the ZBOX must be produced in the so-called 3D MultiView format, in most cases using 3D animation. For interactive applications we support the widely used Unity Realtime Engine. However, real images or more exotic 3D data such as DICOM or MRT images can also be displayed. The processing of existing CAD data sets is also possible.
Simulated Reality, or SR, is the cutting-edge technology in 3D displays. Our SR technology provides an unmatched resolution and brightness, creating an unparalleled immersive 3D experience without the need for glasses.
When we go to the cinema to see 3D movies, we usually wear special 3D glasses to achieve real 3D visual effects. On the contrary, 3D LED display is a kind of LED display, which allows the audience to enjoy the real 3D image with naked eyes. It is installed outdoors. Like the traditional LED display, it is usually installed on the front of the building to attract potential customers passing by to watch the 3D brand story or product details and make a deep impression.
Recently, more and more brands have foreseen the unexpected brand effect of 3D outdoor advertising LED display as a new method. For example, the Swiss watch manufacturer IWC Schaffhausen displayed the details of the 3D watch on the 3d led screen on the landmark Piccadilly light screen in central London; In Chengdu, China, a giant spacecraft broke through the 3D LED screen. Actress Rosamund Parker shot 3D content and promoted the wheel of time in Paris, New York, Madrid and Tokyo. They have attracted extensive interest and Discussion on social media. The rise of 3D LED displays has witnessed the innovative breakthrough of display technology and the refreshing visual impact. This is not only the future of advertising display, but also the breakthrough innovation of the combination of modern public art and display technology.
Autostereoscopic 3D LED display is a technology that does not require additional 3D glasses or any other tools to produce vivid led 3D performance. People can enjoy the immersive experience of spatial dimension with less visual fatigue.
Video processing: after the host outputs the information stream analog signal of the 3D movie video source, the digital DVI signal is generated. The digital signal passes through the video decoding system to output signals for the left eye and the right eye. The signal is processed by the video display module and then loaded onto the LED screen. Through the binocular parallax principle, the audience can see the 3D effect.
At present, all major cities are making naked eye 3D screens. The more famous ones are Chengdu taiguli business district, Guangzhou jiazhaoye, Chongqing Guanyin bridge, Beijing Wangfujing and so on.
All walks of life are making progress, and the display screen is no exception. It is a new breakthrough in the field of outdoor display. Interactive screens may appear in the future, and people may interact with large screens through sounds, gestures, etc.
In order to create these vivid effects, not only hardware such as LED display and control system must have excellent performance, but also corresponding 3D video production, including angles, details and a series of algorithms.
Since 3D LED display is more commercially feasible than traditional outdoor advertising display in the future, consumers and brands pay more attention to 3D display. The 3D image presented by the 3D outdoor advertising display screen is more realistic and convincing than 2D, because it has a larger area, a higher pixel density, and no edge physical elements that make the image look unreal. Therefore, with the 3D LED screen, your brand image and product display will become lifelike. In addition, 3D images bring viewers a new visual experience that 2D images do not, thus stimulating customers to spend more time exploring your brand and products. 3D technology adds depth to your content and makes your advertising more influential.
Naked eye 3D LED display is a kind of 3D effect that can be seen on the screen without wearing professional glasses. Because of its unique display mode, it also caused a sensation when it was listed. Due to the fierce market, the naked eye 3D technology quickly broke through the visual limitations of many viewpoints, and then there was no breakthrough in the naked eye 3D LED display technology. The whole industry can be said to be silent, and full-dimensional vision is still the development direction of the industry. Why not take this step? In the final analysis, its market awareness is not strong and its market capacity is limited, so it is difficult to form a corresponding industrial chain. Even if enterprises develop new products, there is no market in the industry to consume their products, leading to a waste of R & D funds and seriously hindering the enthusiasm of manufacturers in R & D. What is more fatal is that the high price of the naked eye 3D LED display screen has frightened many users. Moreover, the research and development cost of the naked eye 3D display screen is not low, and the enterprise has the research and development ability and cannot bear the risk of long-term return. Therefore, in the future, most enterprises have turned to other sub fields, making the development of naked eye 3D display industry more difficult.
In each subdivision field of LED display screen, all kinds of display screens have very clear application scene positioning. For example, the small spacing display screen is suitable for indoor application display such as conference command center; Transparent screens are suitable for outdoor advertising and glass film pasting screens, and corresponding technologies are further developed according to their clear positioning to promote a wide range of application scenarios and further promote the research and development of industrial products. But there are always exceptions. Compared with other displays, the application scene of naked eye 3D LED display is fuzzy, and the corresponding technology cannot touch the bypass, making the industry development very slow.
Although the 3D display screen is not as good as various subdivision displays in traditional applications, with the development of visual display technology, it can highlight the display mode of the naked eye 3D LED display screen and make it bright in the application of the dance stage. The unique naked eye 3D LED display mode creates a sense of spatial dimension. Combined with the stage lighting, it creates an immersive lighting and film feast, which brings a strong visual impact to the audience. In addition, in recent years, the demand for artistic performances has been rising, and the future prospect of immersive visual performance stage is very broad.

Screens that magically display 3D with no requirement for the viewer to wear glasses? It may sound like some kind of holographic science-fiction, but in a Scottish first, we’ve been lucky enough to get our hands on a massive 65” autostereoscopic Ultra-D screen that does just that.
Well, autostereoscopic 3D displays have been around for a few years. However, the difference in the resolution available on modern 4K screens with Ultra-D’s proprietary algorithms has offered a major leap forward in the capabilities. While viewing angles were extremely limited in earlier HD models, Ultra-D’s screen offers a far wider range of viewing angles. Their award-winning technology generates the required views based on either a 2D + depth-map format, or from a stereoscopic input such as a 3D Blu-ray, and can control the strength of the 3D effect on the fly.
First off it should be noted that this screen, as with most autostereoscopic screens I have seen, is definitely strongest at displaying depth into the screen (positive parallax), compared to typical 3D glasses based systems which can place objects well out in front of the screen as well as into it. So, with this in mind, several animations were created which position objects both deep into the screen as well as in a position well in front of the screen plane, and a mixture of flat planes were tested against full 3D modelled objects. We also tested a commercial 3D Blu-ray to review the results of live action footage in comparison to animated content.
In itself, this is not a deal breaker as the simplicity of just watching 3D on a screen without having to don glasses really does make 3D a viable everyday option. The majority of our team gave positive feedback, although, when experimenting with the 3D strength settings, results were more varied with some viewers unable to look at the screen at higher settings. This would be expected as the science behind stereoscopic displays is based on the average inter-occular distance (space between a person’s eyes) which of course varies from person to person. So an individual with closer set eyes would experience the 3D as being stronger than an individual with wider than average eyes.
Overall the display is great for short, attention grabbing moments such as would be required for digital signage, OOH or for use in public locations like visitor centres or museums. The surprise and depth effect of the 3D naturally grabs your attention and holds it longer than typical 2D screens (this is supported by recent research findings*). Although the quality of the image overall is very good it doesn’t deliver the same level of 3D as a glasses based system so, especially for 3D enthusiasts, the screen wouldn’t present the best solution for home viewing of 3D content where a 3D projector or good quality passive or active glasses based 4K screen would deliver a more immersive experience.
Multiply demonstrated the display recently at the Marketing Society’s Digital Day in Glasgow and will be attending the Museum Association Conference & Exhibition in Manchester Central Convention Centre with the Ultra-D screen on 16 and 17 November 2017. Pop over and see us if you’re nearby or check out the video to see what you think?
Autostereoscopic displays deliver 3D effects without requiring the viewer to wear any special devices such as shutter glasses. For them to work, the eyes must be in the optimal position, which limits the viewer’s freedom of movement. To make sure viewers can enjoy the 3D experience without such restrictions, face tracking can be used.
The illusion of depth in an image is achieved by using special screen-based technologies, inspired by our own visual system. Human brain extracts the depth information by fusing together two separate images acquired by our eyes. Similarly, autostereoscopic displays present a different image to each eye.
The most popular way to achieve that is the parallax barrier. It’s a series of transparent strips that allow each eye to see different regions of the display screen. The “right eye” image is sent to the right eye, and the “left eye” image is sent to the left eye, creating a 3D effect.
A great viewing experience means that viewers are able to move freely and enjoy the best image quality at all times. However, movement can be a challenge for autostereoscopic displays, since they need to project a different image to each eye. To overcome this challenge, manufacturers are relying on face tracking. By tracking head position, eye position and even gaze direction, the system can render the video in respect to the viewer’s current view point.
First of all, the tracker must be quick and efficient. It must be able to detect and start tracking human faces as soon as they appear in front of the display; for example, when a new viewer appears or when the existing one leaves and then comes back again. If the tracker is too slow, the rendering will be adjusted too late, affecting the quality of the 3D.
For example, it’s expected that the tracker will work great in the optimal light (such as daylight). However, the room might get darker, or the only light illuminating the viewer’s face could be the one coming from the display itself. Even in such cases, the tracker must work well so that the rendered content can be adjusted according to the viewer’s position.
Finally, the hardware used for autostereoscopic displays cannot be too expensive. This means that the tracker should work well with mainstream hardware, such as webcams.
A reliable tracker can help provide realistic 3D effects without sacrificing user experience. However, in choosing the right tracker for autostereoscopic displays, it’s important to check whether it meets the necessary requirements. The tracker must be quick, efficient, and able to handle various occlusions and real-life conditions.
FaceTrack – the lightweight face tracking technology developed by Visage Technologies – is a great choice for autostereoscopic displays. It tracks faces, eyes and gaze in real time, helping create an intuitive, glass-free 3D experience without any restrictions when it comes to viewers’ movement of location.
Babenhausen, Germany, March 16, 2020. Technology company Continental is launching its volume-production display featuring autostereoscopic 3D technology on the market in the HMC Genesis GV80 high-line variant. On the screen, the technology displays three-dimensional scales, pointers and objects, for example displaying a stop sign warning in the driver’s line of sight. No special glasses are required to see the three-dimensional warning signal. Instead, Continental uses parallax barriers – slanted slats that divide the image for the viewer – as if looking at real objects, two different, slightly offset views reach the right and left eye, resulting in the three-dimensional image.
Continental’s interior camera, which detects the driver’s line of sight and adjusts the 3D views to their precise head position, plays an essential role. To prevent drivers from focusing their attention on the 3D screen for too long, the camera also employs attention detection to identify potential moments of driver distraction or fatigue. With the 3D visualization of the instrument cluster, Continental is focused on ensuring the driver is not overloaded with information provided by advanced driver assistance systems, conventional displays, communication services and infotainment applications.
“With our volume-production display featuring autostereoscopic 3D technology, we are raising human-machine interaction to a whole new level and laying the foundations for intuitive communication in the connected cockpit of tomorrow,” said Dr. Frank Rabe, head of the Human Machine Interface business unit at Continental. “To ensure that this gain in safety and comfort does not come at the expense of a lean electronics architecture, we integrated various displays in the center console or dashboard into our Cross Domain Hub.”

Convertible video displays that offer both 2D and 3D imaging without the need of any eyewear will mean greater convenience for users who would otherwise have to always carry another accessory. Such autostereoscopic displays have already reached the TV market, but existing technology shows its limitations when close viewing distances are needed. Viewers typically must view these displays from at least 1 meter – eliminating any practical applicability to the smaller screens of mobile devices.
Now, researchers at Seoul National University (SNU), South Korea, have developed a new method of making such convertible displays that not only achieve near-viewing capabilities, but are also simplified with a “shrunken technology architecture”. In a newly-published paper in the journal
For such eyewear-free displays, the only action takes place behind the screen where pixels and optics are layered together to produce the stereoscopic effect. The two primary ways of producing these optically illusive effects are by using either an array of micro-lenses, called lenticular lenses, or an array of micro-filters, called parallax barriers, in front of the image to make its appearance depend on the angle at which it is being seen.
In the case of 2D/3D convertible screens, these layers are active, meaning they can be electronically switched on or off. The gap distance between the image layer and the barrier layer is a key determinant of the viewing distance. Closer stacking of these layers together allows for a closer viewing distance.
The use of this interlayer allows the minimum separation of the image and barrier layers, thus providing the short viewing distance required for the smaller screens of mobile devices.
"The polarizing interlayer approach here will allow high resolution together with design flexibility of the displays, and will be applicable for fabricating other types of displays such as viewing-angle switchable devices,” Lee commented. “Our technology will definitely benefit display companies in manufacturing low cost and light weight 2D/3D convertible displays for mobile applications. Under mobile environments, the weight is one of the important factors.”
This concept not only applies to LC-based 2D/3D displays, but also to OLED-based 2D/3D displays, offering application to a broad range of present and future device designs.
The Optics Express paper concludes: “We have demonstrated a new concept of 2D/3D convertible autostereoscopic LCD based on the LPI for near-viewing applications. The viewing distance of our device was decreased with decreasing the pixel-barrier separation by the introduction of the LPI between the image cell and the switching cell. This approach provides more flexible design in the viewing distance in 3D displays, particularly for mobile applications. The concept of the LPI and similar interlayers will be useful for more sophisticated autostereoscopic display systems.”
I give you the breathless PR that just popped in my inbox, which had the unintentionally funny email header: DSE Press Release IQH3D Glasses-Free Digital Displays Laughed at Digital Signage Expo

So glasses-free 3D displays – more technically known as auto-stereoscopic displays – have been around for at least a decade. There are, indeed, still companies peddling display solutions that require glasses, but they use LED and look wondrously terrible. I saw an example as recently as last month at ISE.
Many, many companies – including relatively big display brands like Philips – have turned up at trade shows through the years trying to generate interest and sales in glasses-free 3D LCD displays and they’ve all came and went. About seven years ago, there was some discussion that it was getting pretty good.
Admittedly, the LCD versions have grown better with time (as happens with almost all tech), but the adoption rate has been minimal within the signage industry and end-users. Once in a while I get PR sent to me about things like glasses-free 3D screens inplaces like travel plazas.
This company’s website is a light in detail as to what’s going on, but it appears to be a lens that goes atop a conventional display panel. The first clue on that is how the Miami firm also markets a 3D-enabling plastic cover that goes on top of a smartphone.
Content is a very fickle, mysterious thing. We all scroll through TV channel guides on screens and wonder Who On Earth? would watch shows, notably many reality shows. But millions do.
