P‐152: High resolution and ultra ‐ fast switching liquid crystal device for Virtual Reality Display

Abstract

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.

P‐92: A Fast Response Time FFS‐LCD with Novel Electrode Design

“…FFS (Fringe Field Switching) LCD shows strong competitiveness due to its advantages of wide viewing angle, high contrast and high Tr% (transmittance) [1]. However, with the improvement of user experience requirements in VR(virtual reality) or gaming display, the motion blur is unacceptable in many scenarios, which has a great correlation with LC response time [2][3][4]. Therefore, gaming and VR products also put forward a higher demand for LC response time (RT).The RT state of FFS LC panels is expressed by the following equation.…”
