Abstract

The present invention provides a method for manufacturing an OLED display panel, comprising: sequentially forming an anode, an organic light-emitting layer, a cathode, and a first optical coupling layer on a base substrate, and further comprising: A second light coupling layer is formed on one side of the cathode, which is formed by arranging several convex structures whose surfaces are arc surfaces. The present invention also provides an OLED display panel. The present invention transmits the light that is to be totally reflected on the surface of the first optical coupling layer through the convex structure on the surface of the second optical coupling layer, thereby reducing the total reflection of the light. Reflection increases the extraction rate of light and improves the external quantum efficiency of the device.

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...
