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.

Abstract: A display panel and a display device are provided. A light-controlling component configured to adjust a signal transmitter is disposed on a light-emitting surface of the signal transmitter of the display panel, thereby allowing modulated light, emitted from the signal transmitter disposed at a predetermined included angle with respect to a bottom surface of a cover plate, to be totally reflected between a top surface and the bottom surface of the cover plate. Total reflection is interrupted at a position where a user's finger touches. Light is received and recognized by a plurality of light sensors on a sensor array after entering the display panel, thereby realizing under-display fingerprint recognition in a large area.
