Abstract

A display panel, a display device, a data processing method, and a medium, wherein the display panel includes: a display component, a line light source component, an image sensing component, and a processing component, the display component is located on the light output side of the line light source component, and the image sensing component is located on the The line light source component is away from the side of the display component; the image sensing component is used to image the light emitted by the line light source component reflected by the fingerprint to be tested; the processing component is connected to the line light source component and is used for sensing The imaging parameter of the component controls the lighting state of the line light source component. In the present application, the processing component controls the lighting state of the line light source component according to the imaging parameters, so that the display panel can obtain a complete fingerprint image, thereby improving the fingerprint recognition accuracy.

Description

technical field [0001] This article relates to the field of display technology, and specifically relates to a display panel, a display device, a data processing method and a medium. Background technique [0002] Fingerprints are inherently unique and invariable features that can be distinguished from others. It consists of ridges and valleys on the skin surface of the fingertips. The composition details of these ridges and valleys determine the uniqueness of the fingerprint pattern. The display panel with fingerprint identification function developed therefrom has been used in personal identity verification, increasing the information security of the display device. [0003] In related technologies, an image sensor and a light source are provided in a display panel with a fingerprint recognition function to realize fingerprint recognition. Specifically, the light source emits light, and the image sensor forms an image according to the light reflected by the fingerprint to ob...
