Novel super fast response vertical alignment‐liquid crystal display with extremely wide temperature range

Abstract

-We have developed a novel super fast response (SFR) thin-film transistor liquid crystal display (TFT-LCD) with an extremely wide temperature range. Nematic liquid crystal molecules with positive dielectric anisotropy are vertically aligned initially. Any gray-to-gray response is forcibly controlled by applying an electric field. Response times of the SFR TFT-LCD are over several times shorter than those of conventional LCDs such as vertical alignment or in-plane switching LCDs.

“…This is still relatively fast at such a low temperature. As reported in [12], the rise time (from 0 to 32nd grayscale without overdrive) of a MVA at 20 o C is as sluggish as 1000 ms.…”

“…3(b). As usual, the response time is defined as For outdoor applications of LCD devices, the slow response time at low temperature causes severe image blurs and reduced color gamut [12]. From Eq.…”

Motion‐blur‐free LCD for high‐resolution virtual reality displays

“…To speed up the response time, one approach is to use a low viscosity liquid crystal (LC) material with an ultra‐thin cell gap . On the device side, triode approach achieves fast rise time and decay time, but it requires two TFTs per pixel and the transmittance is compromised.…”

P‐140: New Nematic LCD with Submillisecond Response Time

“…Recently, a vertical alignment fringe in-plane switching (VA-FIS) mode was proposed and fast response was obtained even at -30C [15]. Its driving scheme is simple and the TFT charging time is fast, but the trade-offs are twofold: increased voltage and decreased transmittance.…”
