ARRAY SUBSTRATE, MANUFACTURING METHOD, AND DISPLAY DEVICE THEREOF

摘要

An array substrate, a manufacturing method, and a display device thereof are disclosed. The array substrate comprises a plurality of pixel units, each of the pixel units comprises a first transparent conductive layer and a second transparent conductive layer (2), the first transparent conductive layer forms a pixel electrode (1), the second transparent conductive layer (2) forms a common electrode (201), and the second transparent conductive layer (2) is disposed on a surface of the pixel unit, an insulating protective layer (131) is provided between the first transparent conductive layer and the second transparent conductive layer (2); wherein a detecting portion (102) is extended from the pixel electrode (1) of each pixel unit; a detecting plate (202) corresponding to the detecting portion (102) is formed of the second transparent conductive layer (2), the detecting plate (202) and the common electrode (201) are transversely separated from each other, and a portion of the insulating protective layer (131) located between the detecting plate (202) and the detecting portion (102) is provided with at least one via hole (3), through which the detecting plate (202) is electrically connected with the detecting portion (201). With the array substrate, the pixel electrode (1) of each pixel unit can be detected individually, thereby improving the detection accuracy.
