Novel, liquid crystal formula to overcome LTPS LCD image sticking without adjustment of gamma code, optical, VHR and IS evaluation

Abstract

In this article, novel n‐FFS liquid crystal material from Slichem was used in order to elevate the anti‐backlight long aging effect; a trace amount of free radical trap HALS‐like additive was added, the principle of which can be expressed via Denisov cycle, confirmed by measuring the temporal VHR changes in test cells; three different resolution (FHD ~ QHD) models paired with N19 and N21 were selected for testing by comparing the actual panel. It is verified that the optimized material greatly improves the image sticking performance of the panel and keeping optical performance.
