Abstract
The present disclosure discloses an organic light emitting diode display panel, a method of manufacturing an organic light emitting diode display panel, and a display device. By forming a film layer having super-hydrophobic properties of the outer water oxygen barrier layer of the thin film encapsulation layer, that is, constructing a rough surface, the surface of the hydrophobic film layer has an extremely thin air layer to reduce direct contact of moisture with the thin film encapsulation layer, thereby reducing the penetration of water and oxygen effectively, improving the water-blocking ability of the film encapsulation layer, and extending the lifetime of the display panel.
