概要

We have developed a super-fast response OCB(Optically self-Compensated Birefringence)mode TFT-LCD by using capacitively coupled driving method(CC driving method). Response time with this driving method has been improved by the twice or more compared with that of a conventionally driven TFT-LCD. Even at a low temperature, 0 degree, this panel can response within one field time, 16.7ms, between every gray scale levels. We developed a prototype OCB mode LCD with newly designed compensation films, that achieved a wide viewing angle characteristic of 160 degrees horizontally and 140 degrees vertically under the condition of that the contrast ratio exceeds 10:1.
