Embodiment Construction

[0022] The specific implementation manner of the present invention will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] to combine figure 1 and figure 2 As shown, an embodiment of the present invention provides a display substrate, including a plurality of pixel regions 100 and a plurality of fingerprint detection regions 200 . Since the accuracy of fingerprint identification is lower than the display accuracy, each fingerprint detection area 200 is set to correspond to a plurality of pixel areas 100 .

[0024] Wherein, each fingerprint detection area 200 includes:

[0025] A plurality of photosensitive sensors 1 arranged corresponding to the area between two adjacent pixel regions 100, the photosensitive sensor 1 includes a first photosensitive sensor and a second photosensitive sensor;

Abstract

The invention relates to the technical field of displaying and discloses a display substrate and a display device. The display substrate comprises a plurality of fingerprint detection areas, each fingerprint detection area comprises a plurality of photosensitive sensors and at least one condensing element arranged on the display side of the photosensitive sensors, light reflected by fingers is condensed by the condensing elements and is projected to the photosensitive sensors, the intensity of light detected by the photosensitive sensors is improved, differences between the intensities of light reflected by fingerprint grooves and fingerprint ridges are increased, the fingerprint grooves and fingerprint ridges are detected accurately, and a fingerprint is precisely recognized accordingly. In addition, by integrating the fingerprint recognition function to the display substrate, the functionality of a display product is enriched.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate and a display device. Background technique [0002] With the development of fingerprint recognition technology, it has been widely used in many fields, such as: mobile phones, tablet computers and TVs in electronic equipment terminals; access control and safes in security protection systems. The realization methods of fingerprint collection mainly include optical, capacitive and ultrasonic imaging technologies, among which the optical fingerprint recognition technology has a relatively large recognition range and relatively low cost. [0003] At present, the optical fingerprint recognition technology used by liquid crystal display is still immature, and most of the existing open patents irradiate the finger with the backlight, the finger diffusely reflects the light beam, and part of the light beam is reflected to the photoelectric sensor device, and ...
