Embodiment approach 1

[0091] Modified Embodiment 1: From the superposition effect of the first nano-silver wire electrode string 131 and the second nano-silver wire electrode string 151, the first side wall 131a of the first nano-silver wire electrode string 131 located on the outermost side and the first nano-silver wire electrode string 131 The distance length of the boundary of the two nanometer silver wire electrode strings 151 is T, T=W=H, that is, viewed from the Y direction, the first nanometer silver wire electrode strings 131 are arranged at equal intervals on the entire touch panel 10, and when this parameter is satisfied In the case of , the touch sensitivity of the touch panel 10 can be further improved.

[0092] Modified Embodiment 2: The width W of the non-conductive region 133 is equal to the distance H between the two first nano-silver wire electrode strings 131, and the non-conductive region 133 is arranged in the middle of the first nano-silver wire electrode string 131, that is, i...

Abstract

The invention provides a touch panel. The touch panel comprises a plurality of first silver nanowire electrode strings arranged at intervals in a first direction and a plurality of second silver nanowire electrode strings arranged at intervals in a second direction, wherein the first silver nanowire electrode strings are insulated from the second silver nanowire electrode strings; each first silver nanowire electrode string comprises a plurality of branches; at least one non conductive region is defined among the branches; and the branches are regularly distributed on the touch panel. The touch panel provided by the invention has the advantages of high touch sensitivity, excellent optical performance and the like. The invention furthermore provides a manufacturing method for the touch panel. The method has the advantages of low cost, simple manufacturing process and the like.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of touch technology, in particular to a touch panel with good touch sensitivity and a manufacturing method thereof. [0003] 【Background technique】 [0004] 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 electrical conductivity. However, with the further development of touch technology, users have put forward higher requirements for touch panels. As a traditional touch material, ITO has shown the following shortcomings: [0005] 1. With the gradual increase in the size of the touch panel, especially when it is applied to a panel above 15 inches, the defects of ITO are becoming more and more prominent. The most obvious defect is that the surface resistance of ITO is too large, which seriously affects the touch panel. touch sensitivity; [0006] 2. In terms o...
