Abstract

The invention discloses a display panel, a preparation method thereof and a display device. The display panel comprises a substrate and a packaging layer, the packaging layer is a laminated film layerformed by stacking an inorganic layer and an organic layer, and a layer of coarse particles are uniformly distributed on one surface, facing the organic layer, of the inorganic layer. The display panel has the technical effects that a layer of coarse 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, the thickness of the organic layer is reduced, and the thickness of the packaging layer and the thickness of the display panel are further reduced.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] OLED (Organic Light Emitting Diode) devices have the advantages of simple structure, fast response, 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 a flexible OLED device, there are a display part, a driver IC and metal wires connecting the two, wherein the driver 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 number of screen bends to reach a commercially acceptable level. From the perspective of thin-film packaging, the bending resistance of the packaging film layer is very important. Co...
