Abstract

The invention discloses an organic light-emitting diode array substrate, a display device and a manufacturing method, and belongs to the field of processing of displays. The array substrate comprises a substrate and a plurality of sub-pixel units, wherein the plurality of sub-pixel units are arranged on the substrate; each sub-pixel unit comprises a composite electrode, an organic material functional layer and a first electrode, which are sequentially arranged on the substrate; the composite electrodes included by different types of sub-pixel units are different in thickness; and the composite electrode, the organic material functional layer and the first electrode included by the same sub-pixel unit form a micro-cavity structure. The plurality of sub-pixel units are arranged on the substrate; and the composite electrodes included by different types of sub-pixel units in the plurality of sub-pixel units are different in thickness, so that the micro-cavity structures of different types of sub-pixel units are different in thickness; the manufacturing technology of the micro-cavity structures is simple and convenient to implement in process; the manufacturing cost is reduced; and the manufacturing efficiency and yield are improved.

Description

technical field [0001] The invention relates to the field of display processing, in particular to an organic light emitting diode array substrate, a display device and a manufacturing method. Background technique [0002] OLED (Organic Light-Emitting Diode, organic light-emitting diode) display device has ultra-light, ultra-thin, high brightness, large viewing angle, low voltage, low power consumption, fast response, high definition, shock resistance, bendable, low cost, simple process, With the advantages of less raw materials, high luminous efficiency and wide temperature range, it is considered to be the most promising new generation display technology. [0003] At present, due to the wide emission spectrum band of OLED light-emitting materials, the color purity of the required light source cannot be met, so the luminous efficiency and brightness of OLEDs are limited, resulting in low contrast and poor display effects of corresponding display devices. Using micro-resonat...
