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 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.

[0037] see figure 1 and figure 2, is a cross-sectional schematic diagram of a silver nanowire conductive film 800. The silver nanowire conductive layer 805 is generally made on a substrate 807, including a plurality of silver nanowires 801 embedded in a matrix 803, and the silver nanowires 801 are arranged on the matrix 803 overlap each other to form a conductive network. The silver nanowires 801 (silvernanowires, SNW for short) have a wire length of 10-300 μm, preferably 20-100 μm, preferably 20-50 μm in length, and the wire diameter (or wire width) of the silver nanowires 801 ...

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 invention relates to the field of touch technology, in particular to a curved touch panel and a wearable device made using the curved touch panel. 【Background technique】 [0002] In capacitive touch panels of traditional smartphones, such as iphone, the material of the touch electrodes is usually indium tin oxide (referred to as ITO). ITO has high light transmittance and good conductivity, and is widely used as a conductive electrode material for touch panels and display panels. However, 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 surfaces such as iwatch or flexible touch screens. [0003] In addition, in terms of manufacturing methods, the original ITO requires a vacuum chamber, a higher deposition temperature and / or a high annealing temperature to obtain high conductivity, resulting in a very expensive overall manufacturing cost of ITO.
