Residual DC characteristic on twisted nematic liquid crystal display on the polyimide surface by the thermal stress
In this study, the threshold voltage and the response time of thermal stressed TN-LCDs showed the same performances on none thermal stressed TN-LCDs. There was little change in TN cells. Also, while increasing thermal stress time, the transmittances of TN-LCDs on the rubbed PI surface were almost the same, but the thermal stability of TN cell was deteriorated.
