Array substrate, display device and control method for fingerprint recognition

Abstract

The embodiment of the invention provides an array substrate, a display device and a fingerprint recognition control method, and relates to the technical field of display. Fingerprints can be recognized through a display area of a display panel under the condition that the display panel displays a picture. Grid lines and data lines which are horizontally and vertically staggered to each other are arranged on a base substrate, and the grid lines and the data lines interact to define at least one sub pixel; and a plurality of photosensitive elements are arranged on the array substrate, the photosensitive elements are arranged between two adjacent sub pixels, the photosensitive elements are connected with driving signal lines and reading signal lines, and the photosensitive elements are used for receiving finger reflected light under the control of the driving signal lines, carrying out photoelectric conversion and outputting converted electric signals from the reading signal lines connected with the photosensitive elements.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display device and a control method for fingerprint identification. Background technique [0002] With the continuous development of display technology, in addition to the display function, the display device can also realize more and more personalized functions, such as online social networking, e-commerce, etc. In order to protect the personal information stored and used in the display device, it is required to display The device can identify and authenticate the identity of the user using the display device before use, so as to realize the privacy protection of user information. [0003] Fingerprints are textures composed of raised ridges and sunken valleys on the fingertip skin. As a lifelong and specific biological feature of the human body, fingerprints are more and more popular because of their ease of use and uniqueness. Applications in the...

Problems solved by technology

[0005] Since the camera of the display device is usually located on the side or back of the housing outside the display panel, for example, the camera of a mobile phone is located on the back of the display screen of the mobile phone. To use the camera position for fingerprint unlocking, it is necessary to turn the mobile phone to the back and attach your finger At the camera, flip the phone to the front to verify whether the fingerprint unlocking is successful. This fingerprint recognition method is inconvenient to operate and affects the comfort of the user.
