Display with fingerprint capture function

Abstract

The embodiment of the invention discloses a display screen with a fingerprint collection function, which includes a display screen cover plate, several display picture elements and several light-sensitive picture elements arranged under the display screen cover plate. Several light-sensitive picture elements are arranged under the display screen cover plate and evenly distributed in the gaps between the several display picture elements. The photosensitive pixel includes a photosensitive element and a field diaphragm, and the diaphragm hole of the field diaphragm is located above the photosensitive element. The photosensitive element receives the light emitted by the display pixel, reflected by the contact part of the finger surface and the display screen cover, and entered by the diaphragm hole of the field diaphragm. In the display screen in this application, a photosensitive pixel is implanted in the display pixel, and the photosensitive pixel uses the display pixel as a light emitter to collect fingerprint images, so that the display screen has a fingerprint recognition function while having a display function, and further The integration, ease of use and user experience of the display are 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
