Embodiment Construction

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] see figure 1 and figure 2 , is a cross-sectional schematic diagram of a silver nano wire conductive film 800, a transparent conductive layer 805 is generally fabricated on a substrate 807, including a plurality of silver nano wires 801 embedded in a matrix 803, and the silver nano wires 801 are arranged in the matrix 803 overlapping each other to form a conductive network. The wire length of silver nano wires 801 (silver nano wires, referred to as SNW) is 10-300 μm, preferably 20-100 μm, preferably 20-50 μm in length, and the wire diameter (or wire width) of nano silver w...

Abstract

The invention relates to the technical field of touch, in particular to a touch panel. The touch panel comprises a cover plate, a first electrode layer and a second electrode layer; the cover plate comprises a first surface and a second surface, wherein the first surface serves as the touch surface; the first electrode layer is located between the second surface and the second electrode layer, the first electrode layer and the second electrode layer are used for detecting multi-point touch, and a nano-silver wire electrode layer is adopted as the second electrode layer.

Description

【Technical field】 [0001] The present invention relates to the field of touch technology, in particular to a touch panel. 【Background technique】 [0002] Touch devices are gradually favored by the electronic communication industry due to their advantages of easy operation, good imaging effect, and multiple functions, and are widely used in information system equipment, home appliances, communication equipment, personal portable equipment and other products. [0003] With the rapid rise of touch panels in the communication industry in recent years, especially the vigorous development of the mobile phone communication industry, touch panels have replaced physical keyboards in one fell swoop and become the preferred product for human-computer interaction in mobile phones. The touch panels with the highest usage rate are mainly resistive touch panels and capacitive touch panels, but for the sake of controllability, ease of use and surface appearance, most users choose capacitive ...
