Abstract

The invention discloses a display panel and a display device. The display panel comprises a human face recognition module and a shading layer, wherein the human face recognition module comprises an infrared light source and an infrared induction unit; the shading layer is positioned on one side, close to the display surface of the display panel, of the infrared induction unit; the shading layer isprovided with an imaging light transmission hole, the imaging light transmission hole comprises at least two imaging light transmission holes with different diameters and is corresponding to the infrared induction unit. The display panel and the display device disclosed by the invention have the beneficial effects that both the human face recognition function and the measurement function can be realized.

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...
