On a giant 100-inch laser display, a football game is in progress. In the photo, beads of sweat are clearly visible on the athletes' foreheads. When you lift the painting up on the white wall, the 0.5mm thickness makes it look like a piece of paper.

"The display has eight different layers of functionality, including an anti-glare layer, a speckle suppression layer, and Fresnel lenses. Fresnel lenses are the core, and they are harder to develop." According to Zhang Yimin, chairman of Chengdu Fester Technology Co., LTD., a product development unit, they are one of the few companies in the world that have mastered this core technology.
