Abstract

The embodiment of the invention discloses an array substrate, a preparation method of the array substrate and a display panel. The array substrate comprises a flexible substrate, a thin film transistor layer and a planarization layer; the thin film transistor layer is formed on the flexible substrate; the thin film transistor layer comprises an inorganic layer; the upper surface of the thin film transistor layer is sunken, so that a concave hole penetrating through the inorganic layer can be formed; the planarization layer is formed on the thin film transistor layer; and the planarization layer fills the concave hole. According to the embodiment of the invention, the structure of the array substrate is improved, the flexibility of the array substrate is improved, the number of manufacturing procedures of the array substrate is reduced, and the manufacturing cost of the array substrate is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate, a method for preparing the array substrate, and a display panel. Background technique [0002] In recent years, foldable display technology has received more and more attention, and has broad application prospects in fields such as portable display devices, wearable digital products, and shopping mall display screens. Flexible display technology is developed based on Organic Light Emitting Diode (OLED) display technology. The array substrate of the OLED display panel usually includes a display area and a bendable area. On the inorganic layer of the bendable area of ​​the array substrate Usually, a deep hole is opened, and then a bendable organic material is additionally filled in the deep hole, so as to improve the flexibility of the bendable region of the array substrate. [0003] However, this way of improving the flexibility of the bendable region of the ...
