Abstract

The invention relates to the technical field of touch control, and provides a touch control module which comprises a substrate, a first bridging layer, a first touch control sensing layer, a second bridging layer and a second touch control sensing layer. The first bridging layer extends on the substrate along a first direction. The first touch sensing layer is arranged on the substrate and comprises a plurality of first touch sensing electrodes, and the first bridging layer is connected with the adjacent first touch sensing electrodes. The second bridging layer is arranged on the first bridging layer, located between the adjacent first touch sensing electrodes and connected with the first bridging layer in parallel. The second touch sensing layer is arranged on the substrate, stretches across the second bridging layer in the second direction and is arranged between the adjacent first touch sensing electrodes. The touch module is provided with the second bridging layer connected with the first bridging layer in parallel, so that the contact resistance between the first touch sensing layer and the first bridging layer can be reduced, the resistance-capacitance load value of the touch module is reduced, and the visibility problem of the first bridging layer is improved.

Description

Technical field [0001] The present invention relates to the field of touch, and more particularly to a touch module having a low contact impedance. Background technique [0002] In recent years, with the continuous development of touch technology, since the transparent conductor can pass through and provide appropriate conductivity, it is often applied to many display or touch-related devices. In general, the transparent conductor can be a variety of metal oxides such as indium tin oxide, ITO, indium zinc oxide (IZO), cadmium tin oxide, CTO or aluminum Acidinum-doped zinc oxide, AZO. However, the films made of these metal oxides cannot meet the flexibility requirements of the display device. Therefore, a variety of flexible transparent conductors are now developed, for example, a transparent conductor made of materials such as metal nanowires. [0003] However, there are many problems that need to be solved by the display or touch devices made in metal nanowires. For example, whe...
