    摘要: In a display device and a repairing method therefor, the display device includes a gate line and two gate-on-array circuits arranged at two sides thereof. Each of the gate-on-array circuits includes a stage coupled to the gate line. Each the stage includes a transistor and a repair circuit. The first source/drain electrode of the transistor is coupled to the gate line, and the second source/drain electrode of the transistor is coupled to receive a clock pulse signal. The repair circuit includes a first terminal coupled to the gate electrode of the transistor, a second terminal coupled to a predetermined potential, and at least one control terminal adapted to receive at least one repair signal to pull the potential on the gate electrode of the transistor to the predetermined potential. The transistor maintains at off-state when the at least one repair signal is supplied to the repair circuit.

    摘要: A shift register of an LCD device operates based on two clock signals and maintains the gate voltage of an output transistor switch using two pull-down transistor switches. The gate voltages of the pull-down transistor switches are switched periodically between the high and low level of the clock signals. During the output period, the transistor switches have negative gate-source voltages so as to reduce leakage.

    摘要: A gate driving circuit having a low leakage current control mechanism is disclosed for providing a plurality of gate signals forwarded to a plurality of gate lines respectively. The gate driving circuit includes a plurality of shift registers. Each shift register includes a driving unit, an energy store unit, a buffer unit, a voltage regulation unit, and a control unit. The driving unit generates a gate signal based on a driving control voltage and a first clock. The buffer unit functions to receive a start pulse signal. The energy store unit provides the driving control voltage through performing a charging process based on the start pulse signal. The control unit generates a control signal based on the first clock and a second clock having a phase opposite to the first clock. The voltage regulation unit regulates the driving control voltage based on the control signal.

    摘要: An apparatus, a shifter register unit, a liquid crystal display device and a method for eliminating afterimage are provided herein, which merely utilize a high voltage source delay discharging phenomenon oriented from a powered-off power device to lead any two of a plurality of existing signal sources employed by the shift register unit to reach a high level used for controlling of charge and discharge of a discharge switching unit corresponding to a pixel unit. Therefore, a power-off afterimage problem could be improved and a signal reset function for power-on also can be achieved.
