Abstract: A single piece type capacitive touch panel uses an etching process to form a frame on periphery of a transparent substrate. An icon layer is disposed in the frame by printing or sputtering. The icon layer completely fills the frame. In addition, one side face of the icon layer has an optical film. Accordingly, the structure of utilizing the frame to combine the icon layer can greatly increase the visible area, enhance the flatness, and avoid thicker thickness caused by climbing effect on curved corner of the conventional icon layer, or Mura phenomenon caused by the stacked structure at the side of the conventional icon layer.

Abstract: A touch sensor device with increased transmittance, increased sensitivity and decreased thickness is disclosed. The touch sensor device includes a substrate. The substrate, from bottom to top, sequentially includes a bottom conductive layer, a bottom insulation layer, a top conductive layer, an electrode layer, a top insulation layer and a substrate material layer. The bottom conductive layer can shield external electromagnetic interference and act as a ground. The bottom insulation layer is provided with an insulation effect. The top conductive layer is used for sensing a touch operation to generate a sensor signal. The electrode layer includes a plurality of first electrode lines, a barrier layer and a plurality of second electrode lines. The top insulation layer is provided with an effect for preventing electrostatic discharge. The substrate material layer is used for protecting the touch sensor device.
