The present disclosure relates to the field of display technology, and discloses an array substrate, which includes a base substrate, a first pole layer, a second pole layer, a planarization layer, a first exposed part, and a touch electrode; On the base substrate, the second pole layer is located on the side of the first pole layer away from the base substrate, and the conductivity of the first pole layer is better than that of the second pole layer; the planarization layer is arranged on the second pole layer On the layer, there are a first touch electrode contact hole and a first pixel electrode contact hole; the first exposed part is located on the first pole layer at a position corresponding to the first touch electrode contact hole; the touch electrode is arranged on the planarization layer Above, the touch electrodes are connected to the first exposed part through the first touch electrode contact holes. The contact resistance between the touch electrode and the drain electrode of the array substrate is small, which can effectively avoid phenomena such as jamming and poor touch control.
Description
technical field [0001] The present disclosure relates to the field of display technology, and in particular, to an array substrate, a method for preparing the array substrate, and a display device installed with the array substrate. Background technique [0002] With the development of display technology, touch screen technology has entered a period of rapid development. Fully embedded touch screens are rapidly developing due to their high resolution. [0003] At present, the fully embedded touch screen is to lay out the touch metal wires inside the thin film transistor, and the touch electrodes and the drains are overlapped. In the display stage, the touch electrode and the pixel electrode form a capacitance to play a display function; in the touch stage, the touch electrode plays a touch function. However, the touch screen in the prior art is prone to phenomena such as jamming and poor touch control. [0004] Therefore, it is necessary to study an array substrate, a met...
