Abstract

The invention provides a display panel and a display device. The display panel can comprise a color film substrate and an array substrate which are oppositely arranged; the liquid crystal layer is arranged between the color film substrate and the array substrate; a reflecting layer is arranged on the surface of one side, close to the liquid crystal layer, of the color film substrate; a sensing layer is arranged on the surface of the side, close to the liquid crystal layer, of the array substrate. In the embodiment of the invention, the infrared light source in the display device emits infrared light to the display panel, part of the infrared light can be received by the sensing layer after being reflected by fingers of a user, and the other part of the infrared light which is not received by the sensing layer can be reflected back, then irradiates the reflecting layer, and is received by the sensing layer after being reflected by the reflecting layer again. The utilization rate of infrared light is effectively improved, the induction amount is increased, and therefore the gesture recognition accuracy is improved.

Description

technical field [0001] The present application belongs to the technical field of display panels, and particularly relates to a display panel and a display device. Background technique [0002] With the development of the display panel field, gesture control of the display panel has become more and more common in people's daily life. The so-called gesture control means that the display panel performs corresponding operations according to the user's gesture, which requires identifying the user's gesture. At present, a light sensor is usually provided on the display panel, and the infrared light emitted by the infrared light source is reflected by the user's finger and received by the light sensor, thereby recognizing the user's gesture according to the received reflected light. [0003] However, when the light sensor receives the reflected light, since the reflected light reflected by the finger tends to diverge, the light intensity shining on the light sensor is attenuated, ...
