High resolution and ultra - fast switching liquid crystal device for Virtual Reality Display

摘要

Head mounted displays (HMD) for virtual reality (VR) require superior electro-optical properties such as high resolution over 2000 ppi and super-fast response time in order to realizing super image quality at near-eyes. Conventional liquid crystal (LC) devices utilizing fringe-field switching (FFS) mode, having response times less than half of conventional FFS mode, contrast ratio is still less than 2000:1, and resolution over 1000 ppi were proposed. In this paper, we propose a vertically aligned liquid crystal device with use of positive dielectric anisotropy LC, which shows high resolution over 2000 ppi, higher contrast ratio and 4 times faster decay response time than that of conventional FFS mode.
