Abstract:
1. A touch sensing element, comprising an insulating substrate and a conductive layer located on a surface of the insulating substrate, wherein the conductive layer comprises: a plurality of first conductive traces arranged at intervals along a first direction of a two dimensional coordinate system, each of the first conductive traces extending along a second direction of the two dimensional coordinate system; a plurality of second conductive traces arranged to form a plurality of second conductive trace columns, wherein each second conductive trace column comprises a plurality of second conductive traces arranged at intervals along the second direction of the two dimensional coordinate system, each second conductive trace column is located corresponding to a lateral direction of a corresponding first conductive trace of the plurality of first conductive traces; each second conductive trace of each conductive trace column is spaced from and forms a mutual inductance with a corresponding first conductive trace; a plurality of color traces, the color traces are located between the first conductive traces and the second conductive traces and insulated from the first conductive traces and the second conductive traces; and a plurality of first conductive leads and a plurality of second conductive leads, each first conductive lead is connected to an end of a respective first conductive trace of the plurality of first conductive traces, and each second conductive lead is connected to an end of a respective second conductive trace of the plurality of second conductive traces; wherein the first conductive traces, the second conductive traces, the color traces, the first conductive leads and the second conductive leads are formed by conductive wires; wherein the first conductive traces, the second conductive traces, the color traces, the first conductive leads and the second conductive leads are grid conductive wires formed by the intersection of conductive wires; wherein the conductive wires forming the color traces are arranged in a grid form, a sawtooth form or a polyline form, and the conductive wires which form the color traces are truncated with intervals of a predetermined length; and wherein the conductive wires forming the color traces define a notch at the truncated portion, the notch is arranged in the form of a line in both the first and second directions of the two dimensional coordinate system.
