Abstract

The invention provides a display panel, a preparation method thereof and a display device, and the display panel comprises a substrate and an OLED device arranged at one side of the substrate; a firstthin film packaging layer which is arranged at one side, deviating from the substrate, of the OLED device; a water absorption and oxygen storage layer which is arranged at one side, deviating from the substrate, of the first thin film packaging layer; a second film packaging layer which is arranged at one side, deviating from the substrate, of the water absorption and oxygen storage layer, wherein the water absorption and oxygen storage layer can absorb water vapor and oxygen in the display panel. According to the technical scheme, the water absorption and oxygen storage layer is arranged toabsorb water vapor and oxygen in the display panel, the water vapor and the oxygen can be effectively prevented from entering the OLED device, so the problems of electrode corrosion and the like caused by the water vapor and the oxygen are solved. Therefore, the reliability and the service life of the display device can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic light emitting diode (Organic Light Emitting Diode, hereinafter referred to as OLED) display device uses OLED to emit light of different brightness. Compared with traditional liquid crystal display device, OLED display device has faster response speed, higher contrast ratio and wider Viewing angle is an important development direction of display devices. [0003] However, OLED display devices have problems such as electrode corrosion caused by oxygen and water vapor, resulting in reduced reliability and lifetime of the device. Contents of the invention [0004] The invention provides a display panel, a manufacturing method thereof, and a display device, so as to improve the reliability and lifespan of the display device. [0005] In order to solve the above problems, ...
