[0021] The method for manufacturing a touch panel according to the first embodiment of the present invention includes the following steps:

[0022] Step S1: if Figure 1A As shown, a substrate 10 is provided, and a conductive layer 20 is formed on a surface of the substrate 10 .

[0023] Specifically, the substrate 10 is a bendable substrate 10 , such as a flexible substrate, and its material may be polyethylene terephthalate (Poly Ethylene Terephthalate, PET) or a thermoplastic material. In a display device with touch function, in order not to affect the display effect, the conductive layer 20 is transparent. Specifically, the transparent conductive layer 20 may be made of indium tin oxide (Indium Tin Oxide, ITOIndium Tin Oxide, ITO). It can be understood that, in other embodiments of the present invention, the conductive layer 20 may also be a metal mesh (Metal Mesh), nano-silver wires or nano-copper wires, etc., which are not limited herein.

Abstract

The invention discloses a manufacturing method of a touch panel. The manufacturing method includes the following steps that a substrate is provided, and a conducting layer is formed in one surface ofthe substrate; the conducting layer is patterned, and forms multiple touch driving electrodes and multiple touch induction electrodes, wherein the multiple touch driving electrodes and the multiple touch induction electrodes are located in different areas of the substrate and are divided through a bending area; the substrate is folded in the bending area, and the multiple touch driving electrodesand the multiple touch induction electrodes are located on different layers formed by the substrate. According to the manufacturing method of the touch panel, the multiple touch driving electrodes andthe multiple touch induction electrodes are patterned and formed through the same conducting layer on the same surface of the substrate, and the manufacturing technology is simple.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch panel and a manufacturing method thereof. Background technique [0002] As an input medium, a touch display device is currently the simplest and most convenient way of human-computer interaction, so the touch display device is increasingly applied to various electronic products. Among them, the capacitive touch display device has become the current mainstream touch display technology due to its advantages of long life, high light transmittance, and support for multi-touch. [0003] The capacitive touch display device includes a capacitive touch panel, and the capacitive touch panel includes a surface capacitive type and a projected capacitive type, and the projected capacitive type can be further divided into a self-capacitive type and a mutual capacitive type. At present, when the touch sensing film of the mutual capacitive touch panel is patterned, the touch driving ele...
