Abstract

The present invention relates to an active organic electroluminescent display panel and its manufacturing method, wherein the active organic electroluminescent display panel includes a substrate, a pixel structure layer, an organic light emitting layer and a cathode pattern layer, wherein the pixel structure layer is configured on the substrate, and the pixel structure layer includes an active element array and an anode pattern layer. The organic light-emitting layer covers at least the anode pattern layer, wherein the organic light-emitting layer includes at least one first organic light-emitting pattern, at least one second organic light-emitting pattern and at least one third organic light-emitting pattern. The cathode pattern layer is arranged on the organic light-emitting layer, wherein the cathode pattern layer includes a first cathode pattern correspondingly arranged on the first organic light-emitting pattern, a second cathode pattern correspondingly arranged on the second organic light-emitting pattern, and a corresponding arrangement A third cathode pattern on the third organic light emitting pattern, and the first, second and third cathode patterns are not connected together.

Description

technical field [0001] The present invention relates to a display panel and a manufacturing method thereof, in particular to an active matrix organic electro-luminescent display panel (Active Matrix Organic Electro-Luminescent Display panel, AMOELD panel) and a manufacturing method thereof. Background technique [0002] The information and communication industry has become the mainstream industry today, especially portable communication and display products are the focus of development. Since the flat panel display is a communication interface between people and information, its development is particularly important. Among them, the organic electroluminescent display (Organic Electro-Luminescent Display, OELD) has the advantages of self-illumination, wide viewing angle, power saving, simple manufacturing process, low cost, wide operating temperature, high response speed and full color, etc., making it Has great potential, so it is expected to become the mainstream of the ne...
