Description

technical field [0001] The present invention relates to the field of touch technology, in particular to an array substrate, a manufacturing method thereof, and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in people's lives. At present, the touch structures included in the touch screen can be divided into: a mutual capacitance touch structure and a self-capacitance touch structure. As for the self-capacitance touch structure, due to its high accuracy of touch sensing and relatively high signal-to-noise ratio, it is favored by major panel manufacturers. [0003] At present, the self-capacitance touch structure uses the principle of self-capacitance to detect the touch position of the finger. Specifically, a plurality of self-capacitance electrodes set on the same layer and independent of each other are set in the touch structure. When the human body does not to...
