  • Patent number: 11151955
    Abstract: A display panel of the present application comprises a driving module. The driving module controls a scan line connected to a sub-pixel to provide a scan signal, and a precharge signal sent earlier than the scan signal. A data signal has the same polarity when the scan line is providing the precharge signal and the scan signal. When the display panel is being driven, the precharge signal can be provided to the sub-pixel before the scan signal is provided to the sub-pixel, and when the polarity of the data signal is the same as the polarity of the data signal when the scan signal is provided to the sub-pixel, so as to turn on and precharge the sub-pixel.

  • Patent number: 10761388
    Abstract: In some embodiments of the present disclosure, it is provided a display panel and a display. The space between the third wire and the gate line of the display panel is greater than the original thickness of the first insulating layer. Since the capacitance is inversely proportional to the space and the signal delay time is proportional to the capacitance, the signal delay time of the display panel can be reduced.
