Abstract

The invention provides an array substrate and a preparation method thereof. The array substrate comprises a substrate layer, a functional layer, a source-drain electrode layer and a first insulating layer. According to the array substrate and the preparation method thereof provided by the invention, eight photomask programs are adopted in total, and a flat layer in the prior art is omitted, so that a photomask of the flat layer is omitted, the production period is shortened, the production cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of display devices, in particular to an array substrate and a preparation method thereof. Background technique [0002] Display devices, such as liquid crystal displays (Liquid Crystal Display, LCD) are commonly used electronic devices, and are widely used in mobile phones and televisions due to their advantages of high image quality, power saving, thin body and wide application range. , personal digital assistants, digital cameras, notebook computers, desktop computers and other consumer electronics products have become the mainstream of display devices. [0003] With the development of flat panel display technology, the demand for liquid crystal displays with high resolution and low energy consumption has been raised. Amorphous silicon has low electron mobility, while Low Temperature Poly-Silicon (LTPS) can be fabricated at low temperature and has higher electron mobility than amorphous silicon. Secondly, the high...
