Problems solved by technology

When the size of the OLED display is small, the voltage drop of the cathode can be ignored; but when the size of the display is large, the voltage drop of the cathode cannot be ignored at this time, and it is directly reflected on the screen, which will cause the problem of uneven display brightness.

Abstract

The invention discloses a display panel, a display device and a manufacturing method of an array substrate. The display panel comprises: a substrate, an array layer, an anode, a pixel definition layer, a light-emitting layer and a cathode that are located on one side of the substrate and are sequentially arranged; and the pixel definition layer comprises a first opening exposing the anode; the light-emitting layer is at least partially arranged in the first opening; and the cathode comprises a first gap located in a non-first opening area. the display panel further comprises a first electric conductor covering the first gap. The resistivity of the first conductor is smaller than that of the cathode. The invention further provides a display device comprising the display panel structure and a manufacturing method of an array substrate which can be applied to the display panel. According to the invention, the difference between the magnitude of current transmitted to the center of the cathode driving signal and the magnitude of current transmitted to the edge of the cathode driving signal is small, so that the problem of uneven display caused by low brightness of the center area of the screen is solved, and the display panel has a better display effect.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a display device including the display panel, and a method for manufacturing an array substrate applicable to the display panel. Background technique [0002] Organic light-emitting diode display devices have many advantages such as white light emission, low driving voltage, high luminous efficiency, short response time, high definition and contrast, large viewing angle, wide operating temperature range, flexible large-area display and full-color display, and are currently mainstream. display technology. [0003] Top-emitting OLED is currently the mainstream OLED panel display technology. Its unique microcavity structure endows top-emitting OLED with advantages such as high aperture ratio, high color purity, and wide color gamut. The top-emitting OLED is composed of a fully reflective anode (RE) and a transflective cathode (TCE). The cathode is usually ...
