Abstract

The invention discloses a display panel and a display device, and relates to the technical field of display. The display panel comprises a display region, wherein the display region comprises a firstdisplay region and a second display region at least partially surrounding the first display region. The display panel comprises an array layer, a liquid crystal layer and a color film layer, wherein the liquid crystal layer is located between the array layer and the color film layer. The display region comprises a first polaroid, and the first display region comprises an electrochromic grating. Inthe stacking direction of the array layer, the liquid crystal layer and the color film layer, the array layer, the liquid crystal layer and at least part of the color film layer are arranged betweenthe first polaroid and the electrochromic grating. In the first display region, the electrochromic grating is used for replacing an original polaroid in the prior art. When the electrochromic gratingis electrified to change color, a polarizing state can be realized in combination with the first polaroid, so that the normal display effect of the first display region is guaranteed; and when the electrochromic grating is not electrified, the whole surface of the first display region is in a colorless transparent state, so that the light transmission effect of the first display region when an under-screen camera is placed therein is guaranteed.

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 and progress of the society, electronic products of the type of camera under the screen are more and more favored by manufacturers and users; The display and camera functions are realized at the same time through the upper and lower layers of polarizers, but due to the existence of the polarizers, the loss of light transmittance is relatively large, which will directly affect the imaging effect of the camera. Therefore, there is an urgent need to invent a display panel that can improve the light transmittance, improve the imaging effect of the under-screen camera, and ensure the display effect of electronic products on the basis of realizing the under-screen camera technology. Contents of the invention [0003] In view of this, the present invention provides a display pan...
