▎ 摘  要

NOVELTY - The transparent touch sensor comprises a transparent first sensing layer which is made of a metal oxide or graphene, and having first capacitive sensing strings and first electromagnetic antenna strings. The first capacitive sensing string is composed of first capacitive sensing units arranged in series along a first direction. The first electromagnetic antenna strings are arranged along the first direction. The first electromagnetic antenna string is provided with a first electromagnetic signal contact and another end is connected to a first connecting wire. The first capacitive sensing units and the second capacitive sensing units jointly form a grid-shaped capacitive sensing unit matrix, and the first electromagnetic antenna strings are crossed with the second electromagnetic antenna strings is joined form a grid-shaped electromagnetic antenna matrix. USE - Transparent touch sensor for reducing local impedance of a transparent conductive film and product. ADVANTAGE - The transparent touch sensor effectively reduce impedance of the sensing strings and increase the efficiency of the signal transmission. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a laminated structure of the touch sensor. Base Layer (10) Colored Bezel (11) Insulative Layer (30) Cover Layer (50) Layers (60)
