Contact-control substrate, manufacture method thereof, and display device

Abstract

The invention provides a touch control substrate and a manufacturing method thereof, and a display device, belonging to the technical field of display. The touch substrate comprises a first touch electrode, a first insulating layer, a second touch electrode and a second insulating layer arranged sequentially on a substrate, and the manufacturing method of the touch substrate comprises the steps offorming a pattern of the second touch electrode and the second insulating layer by a primary patterning process. The technical proposal of the invention can reduce the number of mask plates requiredfor manufacturing the touch substrate, reduce the number of patterning processes for manufacturing the touch substrate, shorten the production time of the touch substrate, and reduce the production cost of the touch substrate.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a touch substrate, a manufacturing method thereof, and a display device. Background technique [0002] The popularity of smart phones and tablet computers has allowed touch screens to penetrate all aspects of human life. Touch screens have become an essential daily necessities for people's production and life in the information age. [0003] Mask (mask) is a necessary mold for touch screen production. Due to its high cost, it occupies a large proportion of the production cost of touch screen. If the existing touch screen supports active pen and other requirements, at least 4 or more masks are required to make, the mask cost accounts for too much of the development cost, which is not conducive to the reduction of production costs; the touch screen production uses yellow light technology, 4 sheets The mask requires at least four yellow light processes, and the production cycle i...

Problems solved by technology

If the existing touch screen has requirements such as supporting the active pen, at least 4 or more masks are required to make it, and the mask cost accounts for too much of the development cost, which is not conducive to the reduction of production costs; the touch screen production adopts the yellow light process, and 4 masks The mask requires at least 4 yellow light processes, and the production cycle is long, which makes the cost of the touch screen higher and limits the development of the touch screen.
