Problems solved by technology

For a-Si devices, the on-off ratio is about 10 5 ~10 6 , if there are process fluctuations or a large channel width is designed, the leakage current will be larger
[0003] Therefore, the current TFT-LCD related technologies still need to be improved

Abstract

The invention provides an array substrate, a preparation method thereof and a display device. The array substrate comprises a resistive structure. The resistive structure comprises the components of a cathode which is electrically connected with a pixel electrode; an anode which is electrically connected with the drain electrode of a thin-film transistor; and a resistive layer which is arranged between the cathode and the anode and is electrically connected with the cathode and the anode; wherein when the voltage of the anode is higher than the voltage of the cathode, the resistive structure is in a low-resistance state; and when the voltage of the anode is higher than the voltage of the cathode, the resistive structure is in a high-resistance state. Through utilizing the resistive structure, leakage current can be greatly reduced, and furthermore pixel holding capability is improved, thereby ensuring high picture quality. Furthermore defects such as Crosstalk, Flicker and Flicker Shift can be prevented.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to an array substrate, a preparation method thereof, and a display device. Background technique [0002] Thin film field effect transistor liquid crystal display (TFT-LCD) has become an indispensable part of modern life. With the advancement of technology, people's demand for display has gradually changed from the previous "seeing" to "interaction", followed by the introduction of high-quality and new technologies such as 4K, 8K high-resolution, Full In Cell touch technology, etc. However, high-tech brings greater challenges to panel design. High-resolution products increase the load of the display area, and Full In Cell takes up part of the charging time. These new technologies have high requirements for the driving and charging capabilities of the panel and the ability to maintain pixels after charging. If these new technologies are used and a good display function is...
