  • Patent number: 12243458
    Abstract: The present application provides a display panel and an electronic device. The electronic device comprises the display panel. The display panel comprises a gate driving unit, a first auxiliary driving unit and scan lines. The first auxiliary driving unit rapidly pulls down the falling edge of the scan signal transmitted in the scan line to reduce the delay of the falling edge of the scan line. Thus, the number of gate driving units in the display panel can be reduced, thereby reducing the width of the frame of the display panel and the electronic device.
