  • Image display systems, shift registers and methods for controlling shift register
    Patent number: 8994637
    Abstract: An image display system includes a gate driving circuit and a data driving circuit. The gate driving circuit generates gate driving signals to drive pixels in a pixel array. The data driving circuit generates data driving signals to provide data to the pixels. At least one of the gate and data driving circuits includes a shift register. The shift register includes flip-flops coupled in serial. Each flip-flop generates output signals in response to an input signal, and is reset in response to a reset signal. One of the flip-flops receives a first output signal of a last stage flip-flop as the reset signal thereof, and at least one flip-flop following the flip-flop receiving the first output signal of the last stage flip-flop receives a second output signal of the flip-flop receiving the first output signal of the last stage flip-flop as the reset signal thereof.
