Abstract

The invention provides an array substrate and a manufacturing method thereof, and a touch panel. The array substrate comprises a display structure layer of a display area and a fan-out structure layerof a non-display area. The fan-out structure layer comprises a protective layer. A signal lead-out line is arranged on one side of the protective layer, and a stress balance structure is arranged onthe other side. The stress balancing structure is used for balancing stress on one side of the protective layer. The display area and the non-display area are connected through the signal lead-out line. The method is used for manufacturing the array substrate, and the touch panel is provided with the array substrate. The invention overcomes the defect that the stress exists between the protectivelayer film and the signal lead-out wire of the touch panel such that the signal lead-out wire is easily broken.

Description

technical field [0001] The present invention relates to the technical field of touch panels, in particular to an array substrate, a manufacturing method thereof, and a touch panel. Background technique [0002] In order to reduce the thickness and quality of the whole machine and improve product quality and competitiveness, the touch function of small and medium-sized liquid crystal display (Liquid Crystal Display, LCD) display devices is mostly implemented in the form of an in-cell touch panel (In CellTouch Panel, ITP). Integrate the touch function on the array substrate (Array Panel). Among them, the touch signal in the display area is transmitted through the signal lead-out line (TP trace) of the fan-out structure in the plane, and fed back to the driver integrated circuit (IC) through the fan-out (fanout) wiring in the non-display area, thereby realizing touch control. Function. Therefore, the integrity of the signal leads of the fan-out structure determines whether th...
