There are no sufficient holes to follow the negative AC bias stress when high frequency is chosen. Due to the operation of the flat panel displays is under AC signal, therefore we discuss the degradation under DC and AC bias stress which include positive and negative bias stress on gate and drain of TFTs. What's more, we discuss asynchronous gate and drain bias stress on TFTs, and study the degradation mechanisms.
