Shaping new advantages of electronic information industry

On a giant 100-inch laser display, a football match is in full swing. On the picture, the sweat on the athlete's forehead is clearly visible. When you lift the picture against the white wall, the thickness of 0.5 mm makes it look like a piece of paper.

"The display has eight layers of different functions, including anti-glare layer, speckle suppression layer and Fresnel lens. The Fresnel lens is the core and the most difficult to develop." According to Zhang Yimin, chairman of Chengdu Feist Technology Co., LTD., a product research and development unit, they are one of the few companies in the world that master this core technology.
