Abstract

The invention provides a display panel and a display device, the display panel comprises a first display area and a second display area, wherein the first display area comprises a first anode, a pixeldefinition layer and a light emitting function layer; the first anode comprises a first transparent conducting layer, a first metal reflecting layer and a second transparent conducting layer which are sequentially stacked, and the first metal reflecting layer is arranged on the first transparent conducting layer and corresponds to the light-emitting unit; the first metal reflecting layer is provided with a groove; the display device comprises the display panel. The grooves are formed in the metal reflecting layer, the first metal reflecting layer in each pixel area is partially and totally reflected, and part of the first metal reflecting layer can be semi-transparent and semi-reflective; when light emitted by the light-emitting functional layer is reflected back and forth between the first reflecting layer and the cathode, a micro-cavity effect is formed, so the transmissivity is improved, the efficiency loss of the under-screen position is not too high, the service life is prolonged, and the imaging quality of the under-screen camera is improved.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] With the increasing popularity and culture of mobile portable devices, high screen-to-body ratio screens have become the future development trend of mobile phones, tablets and other electronic devices because they give users a better visual experience. Mobile electronic terminals, especially mobile phones, pursue the dual advantages of portability and large-screen display. Therefore, mobile phones need higher and higher screen-to-body ratios. Helps increase the screen-to-body ratio. In some related embodiments, a light-transmitting display area can be set on the above-mentioned electronic device, and the photosensitive component can be arranged under the light-transmitting display area. Under the condition of ensuring the normal operation of the light-sensitive component, a full-screen display of the electronic devic...
