Composite transparent electrode, OLED and method for manufacturing thereof, array substrate and display device
First Claim
1. An organic light-emitting diode, comprising a first electrode, a second electrode, and an organic light-emitting functional layer located between the first electrode and the second electrode, wherein the second electrode is a composite transparent electrode, the composite transparent electrode comprising:
- a metal layer;
a transparent conducting oxide layer, wherein the transparent conducting oxide layer is located on a side of the metal layer away from the organic light-emitting functional layer; and
a transparent cover layer located between the metal layer and the transparent conducting oxide layer,wherein the metal layer is electrically connected to the transparent conducting oxide layer;
wherein the transparent cover layer has at least one first through-hole, through which the metal layer is electrically connected to the transparent conducting oxide layer;
wherein the at least one first through-hole comprises a material of the transparent conducting oxide layer therein; and
wherein the at least one first through-hole is a bar-shaped structure.

Abstract
A composite transparent electrode, an organic light-emitting diode and a method for manufacturing thereof, an array substrate and a display device. In the composite transparent electrode, a cover layer (12) is provided between a metal layer (11) and a transparent conducting oxide layer (13), the transparent conducting oxide layer (13) is electrically connected to the metal layer (11). The composite transparent electrode can reduce damages to the metal layer (11) or decrease pressure fall during a sputtering process.
