Abstract

Embodiments of the present invention provide a touch substrate, a manufacturing method and a driving method thereof, and a touch display panel. The touch substrate includes a planar part and at least one bent part, the bent part extends from the edge of the planar part and bends to the side of the planar part, and the planar part is provided with a main layer of a double-layer electrode structure. In the touch module, the bending part is provided with a side touch module with a single-layer electrode structure. The present invention adopts a combined electrode structure of a double-layer electrode structure and a single-layer electrode structure through the touch module, that is, the main touch module of the plane part adopts a double-layer electrode structure, and the side touch module of the bending part adopts a single-layer electrode The structure eliminates the corner wrinkles caused by bending, not only can realize the bending of two adjacent sides, three sides and four sides, but also ensures the touch effect and reliability of the corner area, and minimizes the design of the touch substrate Complexity and manufacturing process difficulty.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch substrate, a preparation method and a driving method thereof, and a touch display panel. Background technique [0002] With the development of display technology, the appearance of mobile terminals is also changing rapidly unconsciously. Not only has it experienced a change from a button screen to a large-size screen to a touch screen, but it is also developing towards a full screen. With the advent of the full-screen era, major panel manufacturers and terminal manufacturers are constantly pursuing a higher screen-to-body ratio. The so-called screen-to-body ratio refers to the ratio of the projected area of ​​the front display area to the projected area of ​​the whole machine. [0003] In order to increase the screen-to-body ratio, related technologies have proposed a variety of full-screen solutions, including digging grooves or holes on the display panel, transp...
