Problems solved by technology

[0006] At the same time, because the reflectivity of silver nanowires is higher than that of ITO, when silver nanowires are used as touch electrodes, white fog will appear on the touch panel visually. The closer the eye is, the more obvious the white fog phenomenon will affect the appearance and light transmittance of the touch panel

Embodiment Construction

[0036] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0037] See figure 1 versus figure 2 , Is a schematic diagram of the cut-away structure of the nano silver wire conductive film 800. The nano silver wire conductive layer 805 is generally fabricated on the substrate 807, including a plurality of nano silver wires 801 embedded in the matrix 803, and the nano silver wires 801 are arranged on the matrix 803 overlap each other to form a conductive network. The wire length of silver nano wires 801 (SNW for short) is 10-300μm, preferably 20-100μm, and preferably the length is 20-50μm. The wire diameter (or wire width) of the silver nano wires 801 is...

Abstract

The invention relates to the technical field of touch, in particular to a curved surface touch panel and a wearable device adopting the same. The curved surface touch panel comprises a cover plate with a first surface and a second surface, a flexible substrate and a silver nanowire conductive layer arranged on the flexible substrate, wherein the first surface is a touch surface; the flexible substrate is positioned between the second surface and the silver nanowire conductive layer; and after the flexible substrate deforms, the curvature of the flexible substrate and the silver nanowire conductive layer is greater than 0, and the silver nanowire conductive layer is compressed. The wearable device comprises a driving control module and the curved surface touch panel, wherein the driving control module is electrically connected with the curved surface touch panel.

Description

【Technical Field】 [0001] The present invention relates to the field of touch technology, in particular to a curved touch panel and a wearable device manufactured by using the curved touch panel. 【Background technique】 [0002] In a capacitive touch panel of a traditional smart phone, such as an iphone, the material of the touch electrode is usually indium tin oxide (abbreviated as ITO). ITO has high light transmittance and good electrical conductivity, and is widely used as current conductive electrode materials for touch panels and display panels. But ITO also has its obvious defects. The conductive electrode formed by ITO is very brittle and lacks flexibility, so it is not suitable for curved or flexible touch screens such as iwatch. [0003] In addition, in terms of the manufacturing method, the original ITO requires a vacuum chamber, a higher deposition temperature and / or a high annealing temperature to obtain high conductivity, which makes the overall manufacturing cost of IT...
