Problems solved by technology

However, zero pollution in the cavity cannot be guaranteed when using evaporation technology to manufacture OLED devices. Foreign particles will exist on the surface of the formed OLED device, and the packaging layer formed on the OLED device for encapsulating the OLED device is relatively thin, resulting in It is very easy to be punctured or cracked by the above-mentioned foreign particles. When the external water vapor and oxygen enter from the edge, it is very easy to go deep into the OLED device from the cracked area in the encapsulation layer, resulting in damage to the OLED device.

Abstract

The invention provides a display panel and a manufacturing method thereof, and a display device. The display panel comprises a light-emitting layer, a packaging layer, a correction layer and a plurality of particles, wherein the packaging layer is located on the light-emitting layer; and when the plurality of particles are located between the light-emitting layer and the packaging layer, the correction layer is located on the light-emitting layer and the plurality of particles, and the correction layer wraps the plurality of particles. According to the above scheme, the plurality of the particles can be wrapped by the correction layer, so the risk that the packaging layer is punctured by the plurality of the particles or cracks occur is reduced, and the reliability of thin film packaging is improved so as to reduce the risk that an OLED device is damaged.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to the manufacture of display devices, in particular to a display panel, a preparation method thereof, and a display device. Background technique [0002] The OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display panel adopts self-luminous technology for image display, and has the advantages of fast response speed, high contrast ratio, and wide viewing angle. [0003] Among them, the biggest advantage of OLED lies in the production of flexible panels, and OLED packaging technology is mainly thin film packaging. However, zero pollution in the cavity cannot be guaranteed when using evaporation technology to manufacture OLED devices. Foreign particles will exist on the surface of the formed OLED device, and the packaging layer formed on the OLED device for encapsulating the OLED device is relatively thin, resulting in It is very easy to be punctured or cra...
