Abstract

The invention relates to the technical field of OLED displayers, in particular to a display screen and a display device comprising the display screen. The display screen comprises a substrate, an anode layer, an organic light-emitting layer, a cathode layer and a packaging layer, wherein the anode layer, the organic light-emitting layer, the cathode layer and the packaging layer are arranged on the surface of the substrate. The display screen further comprises a groove and an electrode lead region, wherein an anode conducting coating and a cathode conducting coating are arranged in the grooveor at the top of the groove; and the electrode lead region comprises an anode lead region and a cathode lead region, the anode layer is connected with the anode lead region through the anode conducting coating, and the cathode layer is connected with the cathode lead region through the cathode conducting coating. The display screen can guarantee that the cathode conducting coating and the anode conducting coating on the packaging layer do not interfere with each other, so that the risk of a short circuit between a negative electrode and a positive electrode is lowered; and when an OLED big substrate comprises multiple display screens, lighting of all the screens can be simultaneously realized, and it is not needed to light up all the individual small screens one by one.

Description

technical field [0001] The invention relates to the technical field of OLED displays, in particular to a display screen body and a display device thereof. Background technique [0002] OLED (English full name is Organic Light Emitting Device, referred to as OLED) has attracted widespread attention in the display field due to its advantages of wide viewing angle, high contrast, low power consumption, fast response, and wide operating temperature range. The OLED screen usually includes a substrate and a packaging sheet, and the bonding of the substrate and the packaging sheet is used to achieve the packaging effect, so as to ensure the isolation of water and oxygen and improve the service life of the product. [0003] The OLED screen needs to be lit and matured. At present, the lighting of the OLED screen in the industry needs to be cut out of a large piece of the screen to produce multiple or hundreds of small pieces of the OLED screen, and then the cutting The single small ...
