51‐1: Optimal Fast‐Response LCD for High‐Definition Virtual Reality Head Mounted Display

Abstract

The fast response LCD is necessary for high-definition and high-refresh rate virtual-reality head mounted displays. In this study, fast-response properties were achieved by SLC-IPS. High transmittance and stable switching were obtained using a oneside branch structure with small irregularities in the electrode.

Alignment control technology of liquid crystal molecules

“…Recently, many studies have been performed in research and development for virtual reality and augmented reality. Fast response has been obtained by the control of the fringe field direction by means of a combination of VA and a lateral electric field, a device of FFS electrode shape, and a specially‐designed aperture in an electrode, such as a slit or a hole 5Mixing of a third substance with LCs: The latest papers are shown in Table .…”

Formation of a fine polymer structure on a plastic substrate through phase separation of a liquid crystal mixture

“…When an electric field is applied to the LC cell, a large spatial elastic energy difference is induced along the domain boundaries because of the effect of 2D confinement with virtual walls. The confinement of LCs with virtual walls developed using various electrode shapes has been actively studied of late [33][34][35].…”

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

“…Consequently, τd is relatively slow compared to that of a vertical alignment mode associated with K3 assuming that γ and d are the same each other for both modes. In order to overcome such an intrinsic issue of both FFS/IPS modes, Matsushima etal., proposed short-range lurch control (SLC)-IPS mode in which the lateral distance l between the two non-responsive LC region exists under the applied field [7,11]. In such a condition, τd is modified into τd = γ /π 2 (K2/d 2 +K1/l 2 ) (1) and when K1 = 2K2 and l = d, τd-SLC = γd 2 /3π 2 K2 = τd-IPS/3, that is, the τd of SLC-IPS mode becomes three times faster than that of the conventional IPS mode.…”
