Display panel and display device

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel includes a first transparent display area, at least one second transparent display area, and a main display area set around at least part of the first transparent display area and at least part of the second transparent display area; the first transparent display area is correspondingly provided with an imaging element, The imaging element collects light through the first transparent display area, the light transmittance of the first transparent display area is greater than the light transmittance of the second transparent display area, and the light transmittance of the second transparent display area is greater than the light transmittance of the main display area , the light enters the imaging element on the back of the display panel through the first transparent display area, and the light enters the face recognition device and / or 3D imaging device on the back of the display panel through the second transparent display area. Through the technical scheme of the invention, the space utilization rate of the transparent display area of ​​the display panel is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of display panels, and in particular, to a display panel and a display device. Background technique [0002] With the rapid development of electronic devices, users have higher and higher requirements for screen-to-body ratio, so that the full-screen display of electronic devices has attracted more and more attention from the industry. Traditional electronic devices such as mobile phones, tablet computers, etc. need to integrate such as front cameras, earpieces, and infrared sensing components, so it is possible to set the camera, earpiece, and infrared sensing elements in the slotted area by slotting (Notch) on the display screen. Components, etc., but these electronic devices are not truly full-screen, and cannot be displayed in all areas of the entire screen. For example, images cannot be displayed in the camera area. In order to achieve a true full-screen, under-screen camera techno...

Problems solved by technology

Traditional electronic devices such as mobile phones, tablet computers, etc., need to integrate such as front camera, earpiece, and infrared sensing components, so it is possible to set the camera, earpiece, and infrared sensing elements in the slotted area by slotting (Notch) on the display screen. Components, etc., but these electronic devices are not truly full-screen, and cannot be displayed in all areas of the entire screen. For example, images cannot be displayed in the camera area. In order to achieve a true full-screen, under-screen camera technology emerged as the times require.

[0003] However, in the existing display panels using under-screen camera technology, the transparent display area can only meet the use of the front camera, and there is a problem that the transparent display area leaves insufficient space for devices used for face recognition devices or 3D imaging. How to improve Insufficient space in the transparent display area of ​​the display panel has become an urgent problem to be solved in the industry
