Display screen with fingerprint acquisition function

Abstract

The embodiment of the invention discloses a display screen with a fingerprint acquisition function. The display screen comprises a display screen cover plate, a plurality of display picture elements and a plurality of light sensing picture elements, wherein the display picture elements and the light sensing picture elements are arranged below the display screen cover plate; the plurality of light sensing picture elements are arranged below the display screen cover plate and uniformly distributed in clearances among the plurality of picture elements; each light sensing picture element comprises a light sensing part, and a field diaphragm of which a diaphragm opening is formed above each light sensing part; the light sensing parts are used for receiving light rays which are emitted through the display picture elements, reflected by parts, in contact with the display screen cover plate, of the finger surfaces, and entered through the diaphragm openings of the field diaphragms. According to the display screen with the fingerprint acquisition function, the light sensing picture elements are implanted into the display picture elements; the light sensing picture elements are used for acquiring fingerprint pictures by treating the display picture elements as light emitters, thus the display has the fingerprint recognizing function while realizing the displaying function, and as a result, the integrity, the use convenience and the user experience of a display can be further improved.

Description

technical field [0001] The invention relates to the technical field of image collection, in particular to a display screen with a fingerprint collection function. Background technique [0002] A display is a display tool that displays electronic files on a display screen through a specific transmission device and then reflects them to the human eye. With the popularization of smart phones and tablet computers, the human-computer interaction interface technology represented by touch screen has been widely favored by the public. At present, more and more display manufacturers have begun to research and launch display screens that can use fingerprint recognition. [0003] Existing display screens that can use fingerprint identification usually require the design of a fingerprint collector independent of the display screen or a fingerprint collector installed at a set position of the display screen. Since the fingerprint collector is independent of the display screen and needs...

AI Technical Summary

Problems solved by technology

Since the fingerprint collector is independent of the display screen and needs to be connected with a corresponding data line, the fingerprint collector designed as one with the display can only be set at a set position on the edge of the display, so that the existing display screens that can realize fingerprint collection have the disadvantages of being unusable. Convenience, low integration and poor user experience
