Description

Technical field

[0001] The invention relates to the structure of a display device and the field of preparation thereof, in particular to an array substrate of a display device and a preparation method thereof. Background technique

[0002] Display devices (such as Liquid Crystal Display (LCD) or Active Matrix / Organic Light Emitting Diode (AMOLED), etc.) are mainly structured by using electric field to control liquid crystal (Liquid Crystal, The light transmittance of LC) is used to display images, or the image is displayed by using current to control the light emission of organic light-emitting materials.

[0003] The above-mentioned displays all need a Thin Film Transistor (TFT) array substrate to achieve voltage or current driving and control of pixels, and the TFT array substrate generally includes scan lines, signal lines, and TFT structures. .

[0004] Traditionally, Low Temperature Poly-Silicon (LTPS) process is mainly used to prepare TFT array substrates to meet the high res...
