- the array substrate Color filter On Array, COA
- the applicant uses two unpublished solutions to improve the light leakage of the curved screen: the first is to increase the width of the black matrix 131; the second is to add a metal layer to block the light leakage part with the metal layer. Although these two methods are effective, but it will affect the panel opening rate, the product penetration rate will decline.
