However, it is difficult to directly probe the pixel voltage electrically. Therefore, measuring the transmittance of the LCD is very helpful to characterize a panel. Looking up the transmittance curve of the liquid crystal cell, the voltage on the pixel can be retrieved. However, the liquid crystal can not respond the pixel voltage in real time and thus such a method may not be used at video frequency. In this paper, various applications of the optical measurement to study the coupled voltage and leakage of pixel electrodes in a TFTLCD are discussed.","PeriodicalId":170859,"journal":{"name":"Proceedings of 5th Asian Symposium on Information Display.

In order to understand trends in LC materials, this paper reviews the development of negative /spl Delta//spl epsiv/ LC materials. While compounds having a 2,3-dicyanophenyl group in the molecular structure have a large negative /spl Delta//spl epsiv/, they have a disadvantage of having high viscosity and insufficient photostability. Pyridazine derivatives exhibit lower viscosity but are not photostable. The difluorophenyl derivatives have been developed. These materials are characterized by high negative /spl Delta//spl epsiv/ values and viscosity. These compound classes are promising materials for liquid crystal mixtures for various applications as ECB, VA TFT liquid crystal display.","PeriodicalId":170859,"journal":{"name":"Proceedings of 5th Asian Symposium on Information Display.
