In terms of display effect, it has high brightness (over 200mcd / m² indoors, over 8000mcd / m² outdoors), wide viewing angle, high contrast and refresh rate, rich colors and accurate reproduction. In terms of physical properties, it is thin and light, modular, long life (up to 100,000 hours), and has a solid and safe structure. It has small seams and flexible splicing methods, and is widely used in many places such as billboards, stages, and shopping malls.
