Response time improvement of OCB mode TFT-LCDs by using capacitively coupled driving method

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