摘要

由于平面电场的非对称设计和挠曲电效应的存在，导致正负帧作用下透过率不同，目视有很明显的闪烁。本文在396 mm（15.6 in）FHD（1 920×1 080）竖双畴结构的基础上，通过LCD expert软件模拟平面电场显示模式正负帧作用下电压-穿透率（Voltage-Transmittance，

V-T

）曲线，同时，实测了像素电极（pixel-ITO）不同线宽线距产品的残留DC（Direct Current）值/Flrcker数值等，得出较好的实验条件，对今后的像素设计有一定的指导意义。

Abstract

Due to the non-symmetrical design of the plane electric field and the presence of the flexo-electric effect

the transmittance ratio different between the positive and negative frame

and the visible flicker is obvious. In this paper

the Voltage-Transmittance (

V-T

) curves of the plane electric field display mode were simulated by the LCD expert software

based on the 396 mm(15.6 in) FHD (1 920×1 080) vertical double-domain structure. At the same time

the residual Direct Current(DC)values and flicker values of different pixel-ITO widths were measured

and the optimal experimental condition was obtained

which was benifit for the pixel design in future.
