See the future trend of LED display from Autostereoscopy

Autostereoscopy it is also called "glasses-free 3D" or "glassesless 3D".

In the last two years, glasses-free 3D LED displays appear frequently. To shock, realistic picture effect to attract everyone's eye. In fact, glasses-free 3D LED display technology has been launched as early as 2013. But there are not many practical application cases. The lack of related technology is the biggest problem hindering the popularization of this technology.


However, with the application of LED display more and more widely, The demand for creative display is higher and higher, Two-dimensional flat display can no longer meet the increasing demand, People want to be able to restore the real world of three-dimensional information,  Therefore, The application of 3D display technology in LED screen has become the focus and direction of research in recent year.



Compared to other screens, 3D LED display features higher brightness, brighter color, higher contrast, ultra-thin and so on. It has a natural and comfortable field of vision and a wider viewing Angle. Creative display can be integrated to create a more realistic and shocking immersive experience scene. Have broad market application prospects.


So what kind of display technology is Autostereoscopy?



The Autostereoscopy technology does not require the use of 3D glasses or other auxiliary tools, It can create a realistic LED 3D effect in front of your eyes. Compared to other 3D screens, It has its own high brightness, no need to rely on external light, its own display can effectively remove molar lines and other advantages, Without causing visual fatigue, you can enjoy the immersive experience of spatial dimension.


The rise of glasses-free 3D technology can be traced back to 2013, and there are two main reasons why the technology has not become popular today:

     1.The definition of the application scenarios of the glasses-free 3D technology LED display is relatively vague,  and is currently only used in specific high-end customized scenarios such as theaters and interactive venues.

     2.High technical threshold and long production cycle: The development of hardware equipment and display system of this technology is still in its infancy and the cost is high. This requires us to understand the basic imaging principles of glasses-free 3D technology.


In a single viewing scenario, suppose our eyes are 60 to 70mm apart, And imagine that our brain is an incredibly complex nervous system. When looking at an object, Using the horizontal visual difference of the image of the object on the retina of both eyes, At the same time, the brain reflects the two parallax images seen by the two eyes through the fusion reflection of the optic nerve center. This creates a three-dimensional picture with depth, which is the basic principle of Autostereoscopy imaging.


The COEX K-Pop Plaza at Samseong Station in Seoul, South Korea, can be said to be the birthplace of the Korean Wave. Just outside the COEX Convention and Exhibition Center, there is a huge led display covering the D'Strict building, a local design company in Seoul that focuses on image, space, and visual experience, designed a huge LED installation art in this place: "Wave", This is actually a huge glasses-free 3D LED curved screen, Created by digital media company Dilussion, K-pop icon SM Entertainment and Samsung Electronics, The realistic effect makes it difficult for the audience to distinguish between true and false from various angles. Surging wave image + HD LED screen + real 3D sound effects, let pedestrians have a feeling as if to be swallowed by the waves.


In addition to the huge waves above, D'Strict has also created an amazing 3D dynamic video wall. This project is located in the bottom lobby of the R&D office building of Nexen Company in South Korea. The 30m wide and 7m high LED media wall is at the entrance of the lobby. The original row of ordinary glass walls has been transformed into a place to show the ‘other world’. 



With the development of modern glasses-free 3D technology, the arrival of 5G and a number of other factors, The 3D LED display function of 4K, 8K and other high-resolution small-pitch display systems may gradually get on track. The future LED small-spacing system relies on a relatively small screen size and seamless curved design, It can accelerate the commercial integration with 3D, VR/AR and other technologies.
