Abstract

Embodiments of the present invention provide a mask, a cathode manufacturing method, and an OLED display device, which relate to the technical field of display devices and can solve the problem of low transmittance of light caused by the high cathode coverage of existing OLED display devices . The mask plate is used to make the cathode of the OLED display device, and the mask plate includes: a first mask plate, a plurality of first openings are opened on the first mask plate, and the plurality of first openings are connected with the OLED display device. The plurality of sub-pixels correspond to each other; the projection of each first opening on the light-emitting layer of the OLED display device covers the light-emitting area of ​​the corresponding sub-pixel; the second mask plate is provided with a plurality of strips The pattern formed by the plurality of second openings can connect the patterns formed by the plurality of first openings. The invention is used for cathode fabrication of OLED display devices.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a mask plate, a cathode manufacturing method and an OLED display device. Background technique [0002] With the rapid development of technology, smart phones are becoming more and more popular. In order to pursue a better visual experience, people continue to put forward higher requirements for the display panel of the mobile phone. At present, the front of most touch-screen smartphones on the market integrates handset, camera and other equipment. The camera is generally set on the top of the screen by opening a hole. In this way, the area where the camera is installed cannot be displayed on the screen, thus causing the screen to not be used effectively. [0003] In order to improve this situation, people began to try to place the camera under the screen, divide the screen display into a normal display area and a low display area, and the infrared camera for face recogni...
