Abstract

The embodiment of the invention discloses a display panel. The display panel comprises a first display area, a third display area and a second display area which are sequentially and adjacently arranged. The display panel comprises a substrate, a pixel definition layer and an inhibition layer, wherein the pixel definition layer and the inhibition layer are sequentially arranged on one side of the substrate; a gap area is arranged between two adjacent pixel openings on the pixel definition layer, and the inhibition layer is located in the gap area; the inhibition layer comprises a first cathode inhibition layer located in the first display area and a second cathode inhibition layer located in the third display area; and the ratio of the area of the orthographic projection of the second cathode inhibition layer on the substrate to the area of the third display area is smaller than the ratio of the area of the orthographic projection of the first cathode inhibition layer on the substrate to the area of the first display area. By arranging the third display area playing a transition role, on the premise that the light transmittance of the first display area is improved through the inhibition layer, the brightness difference of all the display areas is reduced, and therefore the display effect is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display technology has attracted more and more attention from scientific researchers, and is widely used in display fields such as mobile phones, tablets, and TVs. With the rapid development of display devices, users The screen-to-body ratio requirements of display devices are getting higher and higher, making large-size and high-resolution comprehensive display devices a future development direction. [0003] In the existing technology, in order to increase the screen-to-body ratio as much as possible, optical components such as the front camera and face recognition are usually placed under the screen. However, in the existing OLED full-scale display device, the cathode is set on the entire surface. , while the transmittance of the cathode for light is low...
