  • Patent number: 10643558
    Abstract: A driving method of display panel, a display panel and a display device are disclosed. The driving method includes: in a single-frame display time, sequentially applying signals to a plurality of first sub-pixels connected to first data lines in a scanning direction so that: a signal polarity applied to each of a plurality of first white sub-pixels connected to first data lines is opposite to a signal polarity applied to a first sub-pixel which is located at an upstream of the first white sub-pixel along the scanning direction and is adjacent to the first white sub-pixel, and a signal polarity applied to each of a plurality of first colored sub-pixels is identical with a signal polarity applied to a first sub-pixel which is located at an upstream of the first colored sub-pixel along the scanning direction and is adjacent to the first colored sub-pixel.

  • Patent number: 10424235
    Abstract: The embodiments of the application disclose a control device for a gate driving circuit, a display panel and a display device. The control device for a gate driving circuit provided in the embodiment comprises a level shifter and a control module electrically connected with an output of the level shifter. The control module is used for controlling an output signal of the level shifter to be a low level signal when each input clock signal for the level shifter is low.

  • Patent number: 10211821
    Abstract: Embodiments of the present disclosure provide a clock signal transmission circuit, a driving method thereof, a gate driving circuit, and a display device. The clock signal transmission circuit includes an input circuit, a pull-up circuit, a reset circuit, a pull-down control circuit, a pull-down circuit, and a pull-up holding circuit. According to an embodiment of the present disclosure, the clock signal source can be disconnected from each shift register unit in the gate driving circuit before a screen is displayed, preventing malfunctions of the gate driving circuit caused by an undesired high voltage on the clock signal line.
