Abstract

The invention discloses an electroluminescent unit, a display panel and an electronic device. The electroluminescent unit is applied to an under-screen camera area, and the electroluminescent unit comprises a transparent cathode which is used for accessing a circuit cathode of the electroluminescent unit and emitting light of the electroluminescent unit; an anode, used for being connected to a circuit anode of the electroluminescent unit; pixel light-emitting units located between the transparent cathode and the anode and arranged in a stacked mode, and each pixel light-emitting unit comprising a pixel light-emitting layer, an electronic function layer arranged on one side of the pixel light-emitting layer and a hole function layer arranged on the other side of the pixel light-emitting layer; the electroluminescent unit further comprises a connecting layer arranged between every two adjacent pixel light-emitting units, an electronic function layer is arranged on one side of the connecting layer, a hole function layer is arranged on the other side of the connecting layer, and the connecting layer is used for providing electrons for the electronic function layer and providing holes for the hole function layer.

Description

technical field [0001] The application belongs to the technical field of electroluminescence, and in particular relates to an electroluminescence unit, a display panel and electronic equipment. Background technique [0002] In related technologies, each pixel of an active-matrix organic light-emitting diode (AMOLED) is controlled by a thin film transistor (Thin Film Transistor, TFT) below to control the input current, thereby controlling the brightness of each pixel. [0003] The under-screen camera (Camera Under Panel, CUP) can have a good hiding effect on the camera, making the screen position of the electronic device more beautiful and complete. The camera area under the screen needs high transmittance to meet the camera usage conditions of electronic devices. Compared with other areas of the screen, the pixel area of ​​the under-screen camera area is smaller, and the spacing between pixels is also larger. [0004] In the prior art, in order to ensure that the brightnes...
