Organic Light Emitting Diode Array

Abstract

The present invention relates to an organic light emitting diode array, which comprises: a substrate, and a surface of the substrate has a plurality of protrusions arranged at intervals; a plurality of parallel and interval-arranged strip-shaped first electrodes are arranged on the surface of the substrate , and each first electrode is disposed on the top surface of at least one protrusion; a plurality of electroluminescence layers are disposed at intervals on the surfaces of the plurality of first electrodes; a patterned second insulating layer is disposed on the substrate The surface covers the surface of the substrate between the adjacent protrusions, and exposes at least the top surface of each electroluminescent layer; and a plurality of parallel and spaced strip-shaped second electrodes are arranged on the second insulating layer away from the substrate side, the plurality of second electrodes are electrically connected to the plurality of electroluminescent layers, the extension direction of the second electrodes intersects with the extension direction of the first electrodes, and each intersection defines a sub-pixel.

Description

Organic Light Emitting Diode Array technical field The invention relates to an organic light emitting diode (OLED) array and a preparation method thereof. Background technique Organic light-emitting diodes have the characteristic of self-illumination. Therefore, a display screen using organic light-emitting diodes does not need a backlight source, which can significantly save power. Moreover, the display screen using organic light emitting diodes has a large viewing angle, so organic light emitting diodes have become a research hotspot. In the prior art, a plurality of OLEDs are usually fabricated on a substrate to form an array. Wherein, the preparation method of the organic light emitting diode array includes: preparing a thin film transistor (TFT) array on a substrate; forming a first insulating layer on the thin film transistor array; forming a plurality of first insulating layers on the first insulating layer. Electrodes; forming a second insulating layer on the fi...

Problems solved by technology

However, the method of forming the organic light-emitting layer in the prior art is usually vapor deposition, which not only requires a mask, but also requires high-temperature vacuum conditions

Therefore, the preparation process is complicated and the cost is high
