Abstract

Here, we demonstrate world’s first 1 Hz driving fringe-field switching (FFS) LCD via development of low flexoelectric coefficient LCs with high voltage holding ratio (VHR). The evaluation of the 1 Hz driving 13.4-inch FFS LCD laptop panel shows no flicker, and the power consumption is reduced by 83% compared to the 60 Hz driving. We believe this result opens a new chapter of FFS LCDs for low-power consumption.
