Abstract
An array substrate, a method for preparing same, and a display device. The array substrate comprises a substrate (1) and a control electrode layer (2), a giant magnetoresistance layer (3), an insulating layer (4), a pixel electrode layer (5) and a signal electrode layer (6) sequentially provided on the substrate (1) in the direction from near the substrate (1) away from the substrate (1). The control electrode layer (2) comprises a control electrode line (21) and a control electrode (22), and the control electrode line (21) and the control electrode (22) are electrically connected or integrated. The signal electrode layer (6) comprises a signal electrode line (61) and a signal electrode (62), and the signal electrode line (61) and the signal electrode (62) are electrically connected or integrated. The pixel electrode layer (5) comprises a plurality of pixel electrodes (51). The control electrode line (21) and the signal electrode line (61) intersect each other to define pixel units arranged into a matrix. Each pixel unit comprises a pixel electrode (51) and a giant magnetoresistance layer (3). In each pixel unit, the signal electrode (62) is connected to the giant magnetoresistance layer (3), and the pixel electrode (51) is connected to the giant magnetoresistance layer (3). Therefore, the on-state current characteristic of the display device is effectively increased, so as to increase the charging speed and increase the brightness.
Description
technical field [0001] The invention relates to the technical field of liquid crystal displays, in particular to an array substrate, a preparation method thereof, and a liquid crystal display. Background technique [0002] The traditional thin-film transistor liquid crystal display (TFT-LCD, Thin-Film Technology Liquid Crystal Display) occupies a dominant position in the flat panel display market due to its low power consumption and low radiation characteristics. The core component of TFT-LCD is thin-film transistor TFT electrode. Due to the complex preparation process of polysilicon TFT electrode and the disadvantages that it cannot be prepared in a large area, the vast majority of TFT-LCDs currently use hydrogenated amorphous silicon thin-film transistors. [0003] However, hydrogenated amorphous silicon TFT has poor characteristics, especially the low on-state current (Ion), which leads to poor Ion characteristics of liquid crystal displays, and the charging speed of liqu...
