According to a popularization of LCD-TVs, realization of highperformance moving image LCD, such as field sequential color LCD, is required. This paper points out that we have clarified the temperature dependency of viscosity coefficients and flow effects that are great relevance to response of LC comparing among OCB, ECB and VA modes.From mentioned results, we have designed and realized the high-speed response prototyped OCBmode field sequential color TFT-LCD of 15-inch XGA in consideration of temperature dependency.

Here, C is concentration [mol/m 3 ], α is absorption coefficient [m 2 /mol], L is optical path length [m], I 0 is incident light intensity, I 1 is transmitted light intensity and A λ is absorbance, respectively. Measurement accuracy of absorption analysis is in general determined by the detection accuracy of microscopic change of light intensity under strong light irradiation, where the SNR is given by the equation (2),

A color‐field sequential LCD using advanced OCB mode liquid crystal cell and an LED backlight has been developed. Application of a wide‐viewing‐angle‐wide‐band type circular polarizer realized a wide viewing angle and high transmittance OCB mode LC cell. This paper describes the concept of optical compensation and fundamental characteristics of advanced OCB mode LCD.

Abstract— Optically compensated bend (OCB) mode is a promising technology, due to its wide range of viewing angles without gray‐scale inversion or color shift, fast response, high contrast ratio, and wide temperature range. This paper summarizes the fundamental characteristics of OCB mode and discusses the development of field‐sequential‐color displays and 3‐D displays for future high‐quality display applications.
