55.5: Narrow Border Black Photo Spacer Display technology

Abstract

In Black Photo Spacer (BPS) technology, Around gap mura (AGM) is the main reason which limits the application in narrow border display. Using gray tone mask design, AGM can be improved by reduing the film thickness and keeping cell gap uniformity. For the first time, we realize narrow border display application with BPS technology.

54.4: Study on the Dark‐state Light Leakage Mechanism of LCD Splicing Screen

“…Within a certain stress range, The relationship between refractive index and stress is represented by equation (2).…”

“…Based on these quantitative methods, the darkstate light leakage level of the splicing screen can be judged, and it provides guidance for finding ways to improve the peripheral light leakage of the splicing screen using narrow bezel technology. [2][3]…”
