Organic light-emitting display panel and manufacturing method thereof, and electronic equipment

Abstract

Embodiments of the invention disclose an organic light-emitting display panel and a manufacturing method thereof, and electronic equipment. The organic light-emitting display panel comprises an array substrate, a photosensitive recognition array, and photosensitive detection circuits, the photosensitive recognition array comprises a plurality of photosensitive recognition devices, each photosensitive detection circuit comprises a common voltage input layer and a photosensitive detection switch, the photosensitive detection switch comprises a drain electrode metal layer, a first electrode of the photosensitive recognition device is electrically connected with the drain electrode metal layer of the corresponding photosensitive detection circuit, a second electrode of the photosensitive recognition device is electrically connected with the common voltage input layer of the corresponding photosensitive detection circuit, the common voltage input layer and the first electrode of the corresponding photosensitive recognition device are overlapped in a direction vertical to the array substrate, or the common voltage input layer and the drain electrode metal layer of the photosensitive detection circuit are overlapped in the direction vertical to the array substrate to form a photosensitive storage capacitor. According to the organic light-emitting display panel and the manufacturing method thereof, and the electronic equipment, the function of embedded fingerprint recognition is realized by the organic light-emitting display panel, and the effect of fingerprint touch control is realized.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to an organic light emitting display panel, a manufacturing method thereof, and electronic equipment. Background technique [0002] Fingerprints are inherent to each person and are unique. With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. In this way, when a user operates a display device with a fingerprint recognition function, he only needs to touch the fingerprint recognition sensor of the display device with his finger to perform fingerprint recognition. [0003] In the existing display device with fingerprint recognition function, the fingerprint recognition sensor is a separate component, or it is placed on the front of the display device to occupy the area of ​​the display screen, or it is placed on the back of the d...

AI Technical Summary

Problems solved by technology

[0003] In the existing display device with fingerprint recognition function, the fingerprint recognition sensor is a separate component, or it is placed on the front of the display device to occupy the area of ​​the display screen, or it is placed on the back of the display device but does not conform to human operation habits. The user experience becomes poor, no matter it is placed on the front or the back, it is necessary to open holes on the surface of the display device, which affects the manufacturing cost and device reliability
