Organic-light-emitting-diode (OLED) display-screen fingerprint identification device and electronic equipment

Abstract

The invention discloses an organic-light-emitting-diode (OLED) display-screen fingerprint identification device. The organic-light-emitting-diode display-screen fingerprint identification device includes a plurality of sub-pixel units, which are arranged in an array, have the same size, and are used for emitting monochromatic light rays of blue, green and red to carry out mutual combination to form a color image. Three adjacent sub-pixel units are sequentially arranged to form a pixel area. In each pixel area, all the sub-pixel units emit the monochromatic light rays of the different colors, and at least one sub-pixel unit includes a display module group and a light receiving module group. The display module group is used for emitting a monochromatic light ray. The light receiving module group is used for receiving each monochromatic light ray reflected by a finger, and converting a light signal into an electrical signal. The invention also discloses electronic equipment. On the one hand, the pixel area emits the light rays to display the image, on the other hand, the light rays are received by the light receiving module group, and an organic-light-emitting-diode display panel is enabled to have a full-screen fingerprint identification function.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light emitting diode display fingerprint identification device and electronic equipment. Background technique [0002] Organic Light-Emitting Diode (OLED) display devices have the advantages of high luminous efficiency, fast response, easy implementation of flexibility, active light without backlight, etc., so they have been widely used.
