Abstract (en)
[origin: EP1501071A1] A black image transistor and a black image line are added into a liquid crystal pixel circuit to control the insertion of black images. Moreover, a gate driver IC that can separately send two signals is used to switch the switching transistor and black image transistor, and there is a time offset between the two signals. <IMAGE> <IMAGE>
