Embodiment Construction

[0032] At present, the light-shielding layer is made of metal series materials, but the array substrate with metal light-shielding layer is applied to the flexible OLED display panel. Considering the bending characteristics of metal, it is necessary to reduce the size of the light-shielding layer, but still need to meet the requirements to prevent the active layer from being exposed to Even so, since the metal light-shielding layer cannot be completely removed, the metal light-shielding layer will still break due to bending when applied to the flexible OLED display surface, thus affecting the TFT characteristics. The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other emb...

Abstract

The invention relates to the field of display, and discloses an array substrate, a display panel, a display device and a preparation method of the array substrate. The array substrate comprises: a lining substrate; a light blocking layer formed on one side of the lining substrate and made of a flexible material; a first blocking layer formed on one side, deviating from the lining substrate, of thelight blocking layer; and a thin film transistor formed on one side, deviating from the light blocking layer, of the first blocking layer. According to the array substrate, the lining substrate, thelight blocking layer, the first blocking layer and the thin film transistor are sequentially arranged in a stacked mode, the process is simple and easy to operate, and the light blocking layer is madeof the flexible material and is not prone to breakage due to bending and other operations so as o ensure the shading performance of the array substrate, so that the TFT characteristic is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate, a display panel, a display device and a preparation method thereof. Background technique [0002] The top-gate oxide (oxide) TFT (Thin Film Transistor, thin film transistor) is different from the ESL (EtchStop Layer, etch stop layer) TFT. It adopts the structure of setting the gate on the upper part of the active layer, and the oxide TFT will respond to light. Causes changes in TFT characteristics. [0003] To improve this situation, the top-gate oxide TFT is provided with a light-shielding layer. When applied to a flexible OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) array substrate, it may induce defects such as breakage of the light-shielding layer due to bending or the like. Therefore, how to optimize the structure of oxide TFT is particularly important. Contents of the invention [0004] The invention discloses an array s...
