Problems solved by technology

[0003] However, there are still some serious problems in OLED display technology at present, which limit the development of OLED display technology.
For example, when the OLED display device has a common cathode, the cathode of the OLED display device is usually formed by evaporation or sputtering. Due to the low temperature of the evaporation or sputtering process, the film quality is poor, so the impedance of the formed cathode Larger, especially for large-size OLED display devices, the impedance of the cathode is greater, and the cathode impedance will generate a voltage drop, which will cause abnormal OLED display

Abstract

An embodiment of the invention provides an OLED array substrate, a manufacturing method and a display apparatus thereof and relates to the display technology field. A resistance of a second electrode layer can be reduced. The OLED array substrate comprises a first electrode layer, a first pixel definition layer, an auxiliary electrode, an organic layer and the second electrode layer, wherein the first electrode layer is arranged on a substrate and includes a plurality of first electrodes; the first pixel definition layer is arranged on the first electrode layer and includes opening areas and a pixel definition area used for defining the opening areas, and one first electrode is exposed from each opening area; the auxiliary electrode is arranged on the first pixel definition layer and is located in the pixel definition area; the organic layer is arranged in the opening areas of the first pixel definition layer; and the second electrode layer is arranged on the organic layer and the auxiliary electrode, and the second electrode is contacted with the auxiliary electrode and the organic layer. The method and the display apparatus are used for the OLED array substrate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED array substrate, a preparation method thereof, and a display device. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display technology has received great attention and development for a long time due to its many advantages such as self-illumination, fast response, high brightness, and thinness. Currently, the OLED display technology has been mass-produced in mobile products and TV (Television, television) products. [0003] However, there are still some serious problems in OLED display technology at present, which limit the development of OLED display technology. For example, when the OLED display device has a common cathode, the cathode of the OLED display device is usually formed by evaporation or sputtering. Due to the low temperature of the evaporation or sputtering process, the film quality is poor, so the impedance ...
