Abstract

The invention relates to an array substrate, a preparation method thereof and a display panel. The array substrate comprises a substrate body and a buffer layer covering the substrate body. The bufferlayer comprises a first region and a second region surrounding the first region, and the hydrogen ion concentration of the buffer layer located in the second region is greater than that of the bufferlayer located in the first region. According to the array substrate, through combination of hydrogen ions and dangling bonds in the driving structure, the influence of the dangling bonds in the second area on the carrier mobility of the driving structure can be reduced. Therefore, when the array substrate is used for manufacturing the display panel, the brightness of the display sub-panels located in the second area of the buffer layer can be improved, and the brightness uniformity of different OLED display sub-panels manufactured by the array substrate is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate, a preparation method thereof, and a display panel. Background technique [0002] An OLED (Organic Light Emitting Display, Organic Light Emitting Diode) display is a thin-film light-emitting device made of organic semiconductor materials and driven by a DC voltage. [0003] TFT (Thin-film transistor, thin film transistor) is one of the types of field effect transistors. In the traditional technology, TFTs and capacitors are usually used to form the driving structure of the OLED display panel. [0004] In the process of realizing the traditional technology, the inventors found that the brightness uniformity among the display panels manufactured at the same time is poor. Contents of the invention [0005] Based on this, it is necessary to provide an array substrate, a manufacturing method thereof, and a display panel to address the problem of poor brightness...
