Paper Abstract

The multi-domain technology of UV light modified method has been further studied for the application to TFT/LCDs. The additional process is only UV light irradiation through the sub-pixel mask onto the polyimide film. The cell design of pre-tilt control and LC alignment optimization has been studied. The pre-tilt angle difference and the lower pre- tilt angle between the upper and the lower glass substrate are the key to apply this technology to TFT/LCD, the value are more than 2 degree and less than 1 degree, respectively. The process dependency of this technology has also been evaluated and proved its application to TFT/LCD cell process. The opto-electrical characteristics will be described including charge retention, transmittance-voltage curve, and driving life issue.
