Embodiment Construction

[0029] As described in the background art, the functions and structures of existing self-luminous display pixels need to be improved and optimized.

[0030] Therefore, the present invention provides a new self-luminous display pixel. By arranging an optical fingerprint sensing circuit in the pixel, the function of the self-luminous display pixel is improved, the structure is optimized, and the degree of integration is improved.

[0031] In order to make the above objects, features and advantages of the present invention more clearly understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] The first embodiment of the present invention provides a self-luminous display pixel, figure 1 It is a schematic cross-sectional view of the self-luminous display pixel.

[0033] Please refer to figure 1 , the self-luminous display pixel includes a self-luminous circuit (not marked) on the substrate...

Abstract

The invention relates to a self-illumination display pixel. The self-illumination display pixel comprises a self-illumination circuit; the self-illumination circuit comprises a self-illumination device; the self-illumination display pixel further comprises an optical fingerprint sensing circuit; the optical fingerprint sensing circuit comprises a first TFT device and a photosensitive device; and a channel layer of the first TFT device is just below the photosensitive device. By means of the self-illumination display pixel, a fingerprint sensing function can be realized; and furthermore, the integral structure is optimized.

Description

technical field [0001] The present invention relates to the field of photoelectric display, in particular to a self-luminous display pixel. Background technique [0002] Display panels are usually used to display output information of electronic products. A display panel usually 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, display panels with self-luminous display pixels are lighter, thinner and more 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, new designs and optimizations of self-luminous display pixels are required. SUMMARY OF THE INVENTION [0005] The p...
