Abstract

The invention provides an OLED display panel, a preparation method thereof and an OLED display device. The OLED display panel comprises a driving circuit layer, a light-emitting function layer and a packaging layer. The light-emitting function layer is arranged on the driving circuit layer. The packaging layer is arranged on the light-emitting function layer and at least comprises a first organicpackaging layer and a first inorganic packaging layer, and the first inorganic packaging layer is arranged on the first organic packaging layer. The contact surface of the first organic packaging layer and the first inorganic packaging layer is of a convex arc-shaped structure. Therefore, the light extraction rate is improved, and the external quantum efficiency is improved.

Description

technical field [0001] The disclosure relates to the field of display technology, and in particular to an OLED display panel, a manufacturing method thereof, 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 bendability. Therefore, OLED is considered to be a new generation of flat panel display products and technologies following 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, pass a current to the OLED light-emitting layer, and emit l...
