Touch panel

A touch panel, comprising:

• a sensor having a surface defining a touch-view area and a trace area, wherein the sensor comprises:
• an insulating layer having a first surface adjacent to the optically clear adhesive layer and a second surface opposite to the first surface;
• a first transparent conductive layer located on the first surface and having a smallest resistance along an X direction parallel to the first surface;
• a second transparent conductive layer located on the second surface and having a smallest resistance along a Y direction parallel to the second surface, wherein the X direction and the Y direction are perpendicular with each other;
• a plurality of first electrodes arranged on a side of the first transparent conductive layer and along the Y direction;
• a plurality of second electrodes arranged on a side of the second transparent conductive layer and along the X direction;
• a first conductive trace located on the first surface and in the trace area, wherein the first conductive trace is electrically connected with the plurality of first electrodes;
• a second conductive trace located on the second surface and in the trace area, wherein the second conductive trace is electrically connected with the plurality of second electrodes;
• and
• a substrate located on and covering the second transparent conductive layer, the plurality of second electrodes and the second conductive trace;
• an optically clear adhesive layer located on the surface of the sensor;
• and
• a cover lens located on the optically clear adhesive layer and covering the surface of the sensor, wherein a first space is defined between the trace area and the cover lens, and the first space is filled with a first dielectric material with a permittivity that is less than a permittivity of the optically clear adhesive layer.
