Abstract

The invention discloses a display panel and an electronic device. The display panel is provided with an optical sensor area, and the optical sensor area corresponds to an optical sensor. The display panel comprises a plurality of light-emitting units located in the optical sensor area; and the light-emitting unit comprises a first light-emitting subunit and at least one second light-emitting subunit, wherein the first light-emitting subunit comprises a pixel driving circuit. According to the invention, at least two light-emitting subunits are driven to emit light through one pixel driving circuit, so that wiring density of the array substrate in the optical sensor area can be reduced, and the brightness of pixels in the optical sensor area does not need to be improved in the display of thedisplay panel, so that the light transmittance of the optical sensor area of the display panel can be ensured, and the service life of the pixels is not shortened.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and an electronic device. Background technique [0002] In recent years, the rapid development of OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display technology has promoted the rapid entry of curved surface and flexible display products into the market, and technological updates in related fields are also changing with each passing day. OLED refers to a diode that uses organic semiconductor materials and light-emitting materials to cause light emission through carrier injection and recombination under the drive of an electric field. Due to the advantages of light weight, self-luminescence, wide viewing angle, low driving voltage, high luminous efficiency, low power consumption, and fast response speed, OLED display devices are widely used. [0003] An AMOLED (Active-Matrix Organic Light Emitting Diode, Active Matrix Organic Light E...
