Abstract

A touch panel, adapted for a touch control apparatus with a display unit, is disclosed, which comprises: a protection plate, having a covering area and a transparent area formed on a surface thereof; a touch sensitive layer, arranged between the protection plate and the display unit at a position corresponding to the transparent area; a conductive circuit, arranged between the protection plate and the display unit at a position corresponding to the transparent area while being electrically connected to the touch sensitive layer. In addition to the expected touch control functions, the touch panel of the invention can enable more icons to be displayed on the display unit.

Claims

1. A touch panel, adapted for a touch control apparatus with a display unit, comprising:

a protection plate, having a covering area and a transparent area formed on a surface thereof;

a touch sensitive layer, arranged between the protection plate and the display unit at a position corresponding to the transparent area;

a conductive circuit, arranged between the protection plate and the display unit at a position corresponding to the transparent area while being electrically connected to the touch sensitive layer.

2. The touch panel of claim 1, further comprising:

a transparent substrate, disposed under the touch sensitive layer and the conductive circuit at a position above the display unit.
