Touch panel, manufacturing method of touch panel and touch device

Abstract

The invention discloses a touch panel, a manufacturing method of the touch panel and a touch device. The touch panel comprises a substrate, a peripheral lead and a touch sensing electrode. The substrate is provided with a display area, a peripheral area, a folding area and a non-folding area. The peripheral lead is arranged in the peripheral area of the substrate. The touch sensing electrode is arranged in the display area of the substrate and is provided with a first part located in the folding area and a second part located in the non-folding area. The touch sensing electrode is electrically connected with the peripheral lead and is provided with a latticed pattern formed by staggering a plurality of thin wires. Each of the peripheral lead and the touch sensing electrode comprises a plurality of conductive nanostructures and a film layer externally applied to the conductive nanostructures, and the interface between the conductive nanostructures in the second part of the peripheral lead and the touch sensing electrode and the film layer is substantially provided with a coating structure. Therefore, the resistance-capacitance type load value of the touch panel can be reduced, the narrow frame requirement of the display can be met, and the bending performance of the touch panel can be well maintained.

Description

technical field [0001] The present disclosure relates to a touch panel, a manufacturing method of the touch panel, and a touch device including the touch panel. Background technique [0002] In recent years, transparent conductors are often used in many display or touch-related devices because they can allow light to penetrate and provide proper conductivity at the same time. In general, transparent conductors can be thin films made of various metal oxides, such as indium tin oxide (ITO), indium zinc oxide (IZO), cadmium tin oxide (CTO) or aluminum-doped zinc oxide (AZO) thin films. However, these metal oxide thin films cannot meet the flexibility requirements of display devices. Therefore, a variety of flexible transparent conductors have been developed, for example, transparent conductors made of nano-scale materials. [0003] However, there are still many problems to be solved in the above-mentioned process technology of nano-scale materials. For example, when using na...

Problems solved by technology

[0003] However, there are still many problems to be solved in the process technology of the above-mentioned nano-scale materials

For example, when using nanowires to make touch electrodes, the touch electrodes and the lead wires made of metal in the peripheral area must be overlapped, and the overlapping area will cause the size of the peripheral area to be unable to be reduced, resulting in the width of the peripheral area Larger, unable to meet the narrow bezel requirements of the display

To give another example, touch electrodes made of nanowires often take into account optical effects, etc., so that the resistive capacitive loading (RC loading) is relatively large, which is not conducive to general application.
