Ultimate Effect of Blind Vias in LCD Module
Description:
With the development of full screen smartphones, hole digging screens have become the mainstream trend; The hole digging design of LCD modules is prone to poor backlight hole peripheral light efficiency, including hole peripheral light emission, hole peripheral brightness, hole edge brightness lines, and shadow behind the hole. Among them, hole peripheral light emission is currently the biggest problem in the project. This article conducts in-depth and systematic research on the failure mechanism of hole peripheral light emission, using optical software simulation and physical verification; Output a series of optimization solutions from three aspects: design, process, and materials, which have improved the overall taste and visual effect of the product around the holes.
