The introduction of technology into the panel of portable electronic products has become the mainstream of the market. The touch panel mainly has two types of a resistive touch panel and a capacitive touch panel. Among them, the resistive touch panel has insufficient life and reliability, and can not continue to meet the future. As a more stringent product specification and stability required in the field of industrial control and consumer electronics, the m-type (four) panel can also be applied to multiple points. Touch function, therefore, capacitive touch panels have become the mainstream of touch panel development. See Figure 1' for a capacitive touch sensing element! For example, the current touch sensing device includes a substrate 11 and a capacitor circuit 12 disposed on the substrate 11.

The dielectric layer films 122 are formed of an insulating material and are formed at intervals on the connecting blocks 126 of 201229842 to cover the And a part of the connection block 126. Referring to FIG. 3, the bridges 123 are made of a conductive material and connect two adjacent second conductive blocks 125, so that the second conductive blocks 125 and the bridges 123 form a majority. The second conductive unit 128 is arranged in the second direction X of the first direction γ and spaced apart. In general, the first and second directions Υ and X are perpendicular to each other.
