Abstract :
An amorphous silicon (a-Si) TFT gate driver circuit based on decoders is proposed, which guarantees all the TFTs are biased with the duty ratio of 50% or lower and maintains stable LOW outputs. To solve the problem of the large circuit area found in the previous decoder-type gate driver, a new decoder structure composed of parallely connected TFTs is introduced.
