Embodiment Construction

[0047] Such as figure 1 and figure 2 Shown is a schematic structural diagram of the transparent conductor provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the transparent conductor described in the first embodiment includes: a transparent substrate 1 and a touch-sensitive conductive layer 2 disposed on the surface of the transparent substrate 1 . Such as figure 2 As shown, the touch-sensitive conductive layer 2 includes at least two conductive units 21 . The conductive unit 21 is a grid pattern formed of conductive material, and there is a preset gap between two adjacent conductive units 21 .

[0048] This embodiment replaces the ITO conductive film in the prior art by setting a grid-shaped touch-sensitive conductive layer formed of conductive material on the transparent substrate, which can effectively reduce the resistivity of the touch-sensitive conductive layer and improve the transparent conductor. The lead wire is suitable for use in l...

In addition, the manufacturing method of the transparent electric conductor is simple in manufacturing technology, and large-scale production can be achieved.

Description

technical field [0001] The invention relates to touch technology, in particular to a transparent conductor and a preparation method. Background technique [0002] A touch screen is an inductive device that receives touch input signals. Existing touch screens are roughly classified into resistive touch screens and capacitive touch screens. The transparent conductors of the existing resistive touch screens and capacitive touch screens all use nanometer indium tin oxide (Indium Tin Oxides, ITO for short) transparent conductive film. [0003] Existing transparent conductors are generally coated with an ITO conductive film on a transparent substrate by a vacuum ion sputtering process. ITO is a semiconductor material with a high resistivity, which results in poor conductivity of the ITO conductive film, which limits the application of the ITO conductive film to larger touch screens, such as PDAs and All in ones. AIO) or touch screens used on laptops (NoteBook). Contents of th...
