  • Patent number: 9459473
    Abstract: An integrated gate driver circuit includes a control circuit, a plurality of drive stages and a plurality of discharge transistors. The control circuit is configured to output a plurality of clock signals within a frame period and to output a discharge enabling signal within a blanking period of the frame period. Each of the drive stages receives the clock signals and includes an output terminal configured to output a gate driving signal. Each of the discharge transistors is coupled to the output terminal of one of the drive stages and discharges the output terminal according to the discharge enabling signal thereby eliminating the voltage fluctuation of the output terminal in the blanking period.

  • Publication number: 20150042628
    Abstract: A gate driver is used to drive scan lines, a first scan line to a mth scan line. The m is a positive integer. The gate driver comprises driver units, a first driver unit to a mth driver unit, coupled with the first scan line to the mth scan line respectively. The driver units generate scan signals, a first scan signal to a mth scan signal, to drive the first scan line to the mth scan line respectively. The first driver unit, the second driver unit, the (m?1)th driver unit and the mth driver unit have the same circuit structure. The third driver unit and the (m?2)th driver unit have the same circuit structure. The fourth driver unit and the (m?3)th driver unit have the same circuit structure.
