ABSTRACT:
A display apparatus comprises a shift register array. The shift register array comprises a plurality of shift registers. At least one shift register comprises a first transistor, a second transistor, a third transistor, and a driving circuit. The gate and the first electrode of the first transistor receive an input signal. The gate of the second transistor is coupled to the second electrode of the first transistor. The second electrode of the second transistor generates an output signal. The first electrode of the second transistor receives a clock signal. The third transistor is used to pull down a voltage level at the gate of the second transistor. The driving circuit determines an on/off status of the third transistor in response to the input signal and the output signal.
