Abstract

The invention provides a manufacturing method of an OLED display panel. The method comprises the step of sequentially forming an anode, an organic light-emitting layer, a cathode and a first optical coupling layer on a substrate, and further comprises the step of forming a second optical coupling layer formed by arranging a plurality of protrusion structures with the arc-shaped surfaces on one side, away from the cathode, of the first optical coupling layer. The invention further provides the OLED display panel. According to the method, light rays are transmitted out through the protrusion structures with the arc-shaped surfaces of the second optical coupling layer, wherein total reflection of the light rays will happen to the surface of the first optical coupling layer originally, therefore the total reflection of the light is reduced, the take-out rate of the light is increased, and the external quantum efficiency of the OLED display panel is improved.

Description

technical field [0001] The invention relates to the field of preparation of organic photoelectric devices, in particular to an OLED display panel and a manufacturing method thereof. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) has many advantages such as self-illumination, all-solid-state, wide viewing angle, fast response, etc., and has a huge application prospect in flat panel display. OLED is considered to be the successor to LCD (Liquid Crystal Display, Liquid crystal display), PDP (Plasma Display Panel, plasma display panel), a new generation of flat panel display products and technologies. At present, OLEDs are widely used in display and lighting fields. In order for semiconductor light-emitting elements to ensure high functional reliability and low energy consumption, it is necessary to increase the external quantum efficiency (External quantum efficiency) of the element itself. In general, the external quantum effi...
