    摘要: A display device includes: pixel rows including pairs of first and second pixels arranged in turn in each row; first and second gate lines connected to the first and second pixels, respectively; and data lines intersecting the gate lines. Each data line is disposed in between a pair of first and second pixels and connected to the pixels. The pixels are charged by voltages from the data lines in response to signals from the gate lines. The first pixels finish the voltage charging before the voltage charging of the second pixels in the pixel row is finished. The second pixels have a precharging time before the first pixels finish the voltage charging and a main charging time after the first pixels finish the voltage charging. The polarities of voltages charged into the second pixels during the precharging time and the main charging time are the same.

    摘要: A shift register includes a plurality of stages to generate a plurality of output signals, in sequence. Each of the stages includes a driving circuit, a charging circuit, a discharging circuit and a holding circuit. The driving circuit is configured to generate a first output signal in response to a first clock signal or a second clock signal having a phase different from the first clock signal. The charging circuit is configured to charge an electric charge in response to a scan start signal or a second output signal of an adjacent previous stage. The discharging circuit is configured to discharge the electric charge in response to a third output signal of an adjacent next stage. The holding circuit is configured to maintain the first output signal within a first voltage when the first output signal is in an inactive state. Therefore, a parasite capacitance is decreased to prevent a floating of a pull-up transistor.
