Abstract

The embodiment of the invention provides a display panel and a display device. A display area of the display panel comprises a first display area and a second display area. The display panel comprisesa substrate, a display layer, a state switching layer, an optical element and a light homogenizing structure layer. The display layer comprises a pixel definition layer and a plurality of light-emitting devices. A first light-emitting device located in the first display area comprises a first anode, a second light-emitting device located in the second display area comprises a second anode, and the light transmittance of the first anode is larger than that of the second anode. The state switching layer is located on the side, away from the display surface of the display panel, of the display layer, the state switching layer is overlapped with the first light-emitting device, and the light transmittance of the state switching layer in a first state is smaller than that of the state switching layer in a second state. The optical element is located on the side, away from the display layer, of the state switching layer. The light homogenizing structure layer is located between the state switching layer and the optical element and used for diverging light emitted by the state switching layer. The quantity of light received by the optical element can be improved, the problem that the light quantity is uneven after light penetrates through the first display area is solved, and the imaging quality is improved.

Description

technical field [0001] The present invention relates to the field of display technology, 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-to-body 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 amount of space, thereby affecting the screen-to-body ratio. In order to achieve a true full screen, researchers consider the implementation of optical components under the screen. [0003] Set the optical element such as the camera under the light-emitting device of the display panel, that is, set the optical element in the display area, and the position of the optical element can be displayed normally. When the optical elem...
