Abstract

Embodiments of the present invention provide a display panel and a display device. The display area of ​​the display panel includes a first display area and a second display area; a substrate; a display layer, the display layer includes a pixel definition layer and a plurality of light-emitting devices, the first light-emitting device located in the first display area includes a first anode, and is located in the first The second light-emitting device in the two display areas includes a second anode, and the light transmittance of the first anode is greater than that of the second anode; the state switching layer is located on the side of the display layer away from the display surface of the display panel, and the state switching layer is connected to the first anode. The light-emitting devices are overlapped, and the light transmittance of the state switching layer in the first state is smaller than that in the second state; the optical element is located on the side of the state switching layer away from the display layer; the uniform light structure layer is located on the state switching layer and Between the optical elements, it is used for diffusing the light emitted by the state switching layer. The invention can increase the amount of light received by the optical element, improve the unevenness of the light amount after the light penetrates the first display area, and improve the imaging quality.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] With the development of display technology, people not only require a smooth user experience for the electronic products they use, but also have higher and higher requirements for visual experience. High screen ratio has become the current research direction. For electronic products, the setting of optical components such as the front camera will inevitably occupy a certain space, thus affecting the screen ratio. In order to achieve a true full screen, the researchers considered the realization of optical components under the screen. [0003] The optical element such as a camera is arranged below the light-emitting device of the display panel, that is, the optical element is arranged in the display area, and the position of the optical element can be displayed normally. When the optical element is ...
