  • Shift register unit, method of driving shift register unit, gate driving circuit, and display device
    Patent number: 11100835
    Abstract: A shift register unit, a method of driving a shift register unit, a gate driving circuit, and a display device are disclosed. The shift register unit includes an input circuit and an output circuit. The input circuit is configured to write an input signal of the input terminal to the first node in response to an input control signal, so as to control a level of the first node. The output circuit is configured to receive a clock signal of the clock signal terminal and output a scanning signal through the pixel signal output terminal under control of the level of the first node. The output circuit includes a variable resistor, and the variable resistor is configured to adjust a level of the scanning signal according to a resistance value of the variable resistor.

  • Gate driving unit circuit pair and driving method thereof, gate driving circuit and display device
    Patent number: 10818261
    Abstract: A gate driving unit circuit pair and a driving method thereof, a gate driving circuit and a display device are provided. The gate driving unit circuit pair includes two gate driving unit circuits, each of which includes a first output sub-circuit, a second output sub-circuit, and a coupling and isolation sub-circuit. The coupling and isolation sub-circuit is configured to: if the first output sub-circuit outputs signal, isolate the signal of the first output terminal from the signal of the second output terminal; or else, couple the signal of the first output terminal to the second output terminal.
