Display panel and electronic apparatus

Abstract

The invention provides a display panel and an electronic apparatus. The display panel includes an array substrate, a plurality of organic light-emitting structures, a fingerprint recognition unit anda first color filter, wherein the array substrate includes a base substrate, and the plurality of organic light-emitting structures includes a first organic light-emitting structure, a second organiclight-emitting structure, and a third organic light-emitting structure. In a fingerprint recognition phase, the first organic light-emitting structure and / or the second organic light-emitting structure serve / serves as the light source of the fingerprint recognition unit; the emergent light of the first organic light-emitting structure and / or the second organic light-emitting structure has a firstspectral range; the transmission spectral range of the first color filter is a second spectral range; a spectral range corresponding to visible light and near infrared light is a third spectral range;the first spectral range is within the second spectral range; the second spectral range is within the third spectral range; and light of at least part of wavelength bands which are within the third spectral range and outside the second spectral range is absorbed or reflected by the first color filter. With the display panel and the electronic apparatus of the invention adopted, the influence of ambient light can be reduced, and the accuracy of fingerprint detection results can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and electronic equipment. Background technique [0002] Because fingerprints are innate and unique to each person. 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, before operating the display device with fingerprint identification function, the user only needs to touch a specific area of ​​the display device with his finger, and the authority verification can be performed through the identification of the fingerprint identification unit, which simplifies the authority verification process. According to the working principle, fingerprint recognition can include optical fingerprint recognition and ultrasonic fingerprint recognition. [0003] Fingerprints are composed of a series of ridges and valleys on th...

AI Technical Summary

Problems solved by technology

The fingerprint identification unit usually includes a photodiode and a storage capacitor, which together convert the reflected light via the touch body into a current / voltage signal, but due to the presence of ambient light (sunlight or light, etc.), the fingerprint identification is reduced. Accuracy of detection results
