ORGANIC LIGHT-EMITTING DIODE DISPLAY PANEL AND MANUFACTURING METHOD THEREOF

摘要

An organic light-emitting diode (OLED) display panel and manufacturing method thereof. The method of manufacturing the OLED display panel comprises forming an anode (2), an organic light-emitting layer (3), a cathode (4) and a first optical coupling layer (5) sequentially on a substrate (1), and forming a second optical coupling layer (6) on a side, away from the cathode (4), of the first optical coupling layer (5) by arranging a plurality of protrusion structures with arc-shaped surfaces. Light that would be totally reflected from a surface of the first optical coupling layer are transmitted out through the protrusion structures with the arc-shaped surfaces of the second optical coupling layer, therefore the total reflection of the light is reduced, the light extraction efficiency is increased, and the external quantum efficiency of the device is improved.
