Abstract

The invention discloses a display panel, a preparation method thereof, and a display device. The display panel includes a substrate and an encapsulation layer, wherein the encapsulation layer is a stacked film layer formed by stacking an inorganic layer and an organic layer; the inorganic layer faces One side of the organic layer is evenly distributed with a layer of rough particles. The technical effect of the present invention is that a layer of rough particles is formed on the surface of the inorganic layer, the roughness of the surface of the inorganic layer is improved, the subsequent organic layer can be better spread and leveled, and the thickness of the organic layer is reduced, Further reduce the thickness of the encapsulation layer and the display panel.

Description

technical field [0001] The present invention relates to the field of display, and in particular, to a display panel, a preparation method thereof, and a display device. Background technique [0002] OLED (Organic Light Emitting Diode) devices have the advantages of simple structure, fast response speed, active light emission, low power consumption, etc., and have been widely used in display fields such as mobile phones, tablets, and TVs. With the development of product differentiation, flexible and folding screens have become a trend. In the flexible OLED device, there are a display part, a driving IC, and metal traces connecting the two, wherein the driving IC is distributed on the lower frame of the panel. At present, more and more mobile phone manufacturers are trying to launch bendable mobile phones, requiring the screen to be bent to a commercial level. From the perspective of thin film packaging, the bending resistance of the packaging film layer is very important. ...
