Abstract

A self-luminous display pixel, comprising: a self-luminous circuit, the self-luminous circuit includes a self-luminous device, and the self-luminous device includes a bottom electrode layer; the bottom electrode layer is a non-light-transmitting layer; the self-luminous display pixel It also includes an optical fingerprint sensing circuit, the optical fingerprint sensing circuit includes a first TFT device and a photosensitive device, and the channel layer of the first TFT device is located directly under part of the bottom electrode layer. The self-luminous display pixels can realize the fingerprint sensing function, and the overall structure is optimized.

Description

technical field [0001] The invention relates to the field of photoelectric display, in particular to a self-luminous display pixel. Background technique [0002] Display panels are generally used to display output information of electronic products. The display panel generally has an array substrate, and the array substrate includes display pixels. Among all kinds of display pixels, since self-luminous display pixels do not require a backlight source, display panels with self-luminous display pixels are lighter, thinner and power-saving. Therefore, display panels with self-luminous display pixels are an important development direction of current display panels . [0003] However, the structure and function of existing self-luminous display pixels need to be improved. [0004] In order to improve the structure and function of self-luminous display pixels, a new design and optimization of self-luminous display pixels is required. Contents of the invention [0005] The pr...
