Abstract

The present disclosure provides an OLED display panel, a manufacturing method thereof, and an OLED display device. The OLED display panel includes a driving circuit layer, a light-emitting functional layer and an encapsulation layer. The light-emitting functional layer is disposed on the driving circuit layer. The encapsulation layer is arranged on the light-emitting functional layer, and includes at least a first organic encapsulation layer and a first inorganic encapsulation layer, and the first inorganic encapsulation layer is arranged on the first organic encapsulation layer. Wherein, the contact surface of the first organic encapsulation layer and the first inorganic encapsulation layer has a convex arc structure. In order to improve the extraction rate of light, thereby improving the external quantum efficiency.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to an OLED display panel, a method for manufacturing the same, and an OLED display device. Background technique [0002] Organic Light Emitting Diode (OLED) display products have the advantages of thinness, fast response, wide viewing angle, high contrast, and flexibility. Therefore, OLED is considered to be a new generation of flat panel display products and technologies after Liquid Crystal Display (LCD), and has received more and more attention and applications. [0003] The OLED display panel includes a base layer, a thin film transistor (Thin Film Transistor, TFT) driving layer, an OLED light-emitting layer, an encapsulation layer (Thin Film Encapsulation, TFE) and the like from bottom to top. The light-emitting principle of the OLED display panel is to deposit an OLED light-emitting layer between two electrodes, and pass a current to the OLED light-emitting lay...
