From 2014 to 2015, when the development of the free glass 3D led display was hot, the strength of the R&D team was enormous. Liad, Alto Electronics, Chau Ming, Sansi, Zip Optoelectronics, Easystar, Mai Rui Optoelectronics and other companies are in the ranks of R & D. From the scale and strength of the company, it can be seen that LED display companies invest a lot in R&D of the free glass 3D technology, but even so, the free glass 3D technology can not compare with the small pitch, thus forming a mature market.
It is understood that most of the free glass 3D technologies are in the research and development stage, and its research and development are divided into two directions, one is the development of hardware devices, and the other is the development of display content processing. In the past few years, free glass 3D led display
screens have been launched. In 2015, 3D technology was rushed to be developed by major LED display manufacturers. However, in general, companies that can independently developfree glass 3D led displays are rare in China. Because of the difficulties, the real sense of free glass 3D led display technology can not be mature applications.
At this stage, free glass 3D led displays are all indoor products, and most manufacturers do not have the ability to research and develop outdoor free glass 3D led displays, which also limits the promotion of the free glass 3D led display. It can be seen that for many years, led display manufacturers have never given up R&D for free glass 3D technology, but it takes a certain amount of time to achieve a large number of applications in the field of LED display applications and gain market acceptance.
