Touch sensitive element and touch screen comprising same

Abstract

A touch sensitive element comprises insulating base materials and a conducting layer arranged on the insulating base materials, wherein the conducting layer is located on one surface of the insulating base materials. The conducting layer comprises a plurality of first conducting wire traces which are arranged at intervals along a first dimension direction of a two-dimensional coordinate system, and each first conducting wire trace extends along a second dimension direction of the two-dimensional coordinate system. A plurality of second conducting wire traces are arranged into a plurality of second conducting wire trace rows, wherein each second conducting wire trace row comprises a plurality of second conducting wire traces which are arranged at intervals along the second dimension direction of the two-dimensional coordinate system, and each second conducting wire trace row is located on the side direction of each first conducting wire trace in a corresponding mode. Each second conducting wire trace in each second conducting wire trace row and a corresponding first conducting wire trace are mutually spaced and form mutual inductance. The conducting layer of the touch sensitive element is formed on one surface of the insulating base materials, and the structure and manufacture procedure are simple. The invention further provides a touch screen comprising the touch sensitive element.

Description

technical field [0001] The invention relates to a touch sensing element, in particular to a single-layer conductive layer touch sensing element and a touch screen with the touch sensing element. Background technique [0002] As a simple way of human-computer interaction, the touch screen is widely used in various electronic devices, such as mobile phones and IPADs. [0003] A touch screen generally includes a panel and a touch sensing element attached to one side of the panel. The touch sensing element consists of an insulating layer, a sensing layer and a driving layer located on two opposite surfaces of the insulating layer. The sensing layer includes several non-intersecting sensing traces extending along a first direction, and the driving layer includes several non-intersecting driving traces extending along a second direction. The first direction is not parallel to the second direction. The sensing trace and the driving trace are separated by the insulating layer, whi...
