41.1: Invited Paper: High Performance TFT‐LCDs for AVC Applications

Abstract

Advanced-Super-View (ASV) technology is proposed to achieve high performance TFT-LCDs, in this paper.The ASV-LCDs have high performance characteristics such as high contrast, high brightness, wide-viewing angle, and fast response. The ASV is very promising technology for applications of Audio-Visual Computing.

Bending Angle Effects on the Multi-Domain in-Plane-Switching Liquid Crystal Displays

“…The electric free energy, , under the effect of a static electric field which is induced by a constant voltage is given by (6) where , and are the electric flux density, the electric field intensity, and the LC dielectric constant matrix, respectively. The potential distribution could be solved as a variational problem using FEM, where the LC device is discretized by using first-order rectangular element and the periodic boundary condition is applied in the plane.…”

“…Fast response time, high contrast ratio, wide viewing angle, and weak color shift are the major technical thrusts for large screen LCD TV and computer monitor applications [1]. To widen viewing angle, multi-domain vertical alignment (MVA) [2], [3], patterned vertical alignment (PVA) [4], [5], advanced super view (ASV) [6], [7], and in-plane switching (IPS) modes [8]- [10] have been developed. IPS mode inherently exhibits a wide view angle due to the in-plane reorientation of the LC directors.…”

Axially Symmetric Continuous Domain Vertical Aligned LCD: Poincare Sphere Analysis of Brightness Enhancement by Using Circular Polarizer

“…With the quick development and expansion of the liquid crystal display market, fast response time, high contrast ratio and wide viewing angle are critically required in large size monitors and television (TV) applications [1][2][3][4][5][6][7][8][9]. Fujitsu Display Technologies first reported the automatic domain formation (ADF) technology [10][11][12] for achieving a high quality multi-domain vertically aligned liquid crystal display (MVA-LCD) in 1998.…”

Dopant-Enhanced Vertical Alignment of Negative Liquid Crystals

“…In the normal incidence, the contrast ratio is insensitive to the incident light wavelength, LC cell gap, and operating temperature [3]. For wide-view applications, e.g., LCD TVs and desktop monitors, multi-domain vertical alignment (MVA) [4], advanced super view [5], and patterned vertical alignment (PVA) [6] have been developed. To realize the useful electro-optic effects using longitudinal electric field, the VA cells require a negative dielectric anisotropic LC mixture, i.e., De ¼ e k À e ?…”
