Abstract

The invention discloses a display panel and a display device. The display panel includes: a face recognition module, including an infrared light source and an infrared sensing unit; a light-shielding layer, the light-shielding layer is located on the side of the infrared sensing unit close to the display surface of the display panel, and the light-shielding layer has an imaging light-transmitting hole, and the imaging light-transmitting hole and the infrared Corresponding to the sensing unit, wherein the imaging light-transmitting hole includes at least two kinds of imaging light-transmitting holes with different diameters. The invention can realize the face recognition function and also has the measurement function.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] With the development of science and technology and the improvement of user performance requirements for electronic products, designs that apply face recognition to electronic products have appeared in the prior art. The principle of face recognition is to project the object through the dot matrix infrared light source, and then use the infrared camera to shoot the projected object, identify the distortion of the projection dot matrix, and restore the 3D information. However, face recognition in the prior art does not have the functions of measuring the distance and size of the face, that is, measuring the distance between the face and the electronic product and measuring the size of the face. [0003] Therefore, it is an urgent technical problem in this field to provide a display panel and a di...
