Abstract
A touch pad structure includes a first substrate, a joining layer, a guide light layer, a second substrate and an illuminant component. The joining layer is adhered to a side of the first substrate. The guide light layer is disposed next to the joining layer. The second substrate is disposed next to another side of the first substrate and provides electrical circuit and a conductor with sensing loci. The illuminant component is provided beside periphery of the guide light layer to connect with the electrical circuit. The electrical circuit receives change of coupling capacitance at the time of an object touching the touch pad so as to control “On” and “Off” of the illuminant component.
Claims14
A touch pad structure comprising:
- a first substrate with a first side and a second side being opposite to each other;
- a joining layer being adhered to the first side;
- a guide light layer being disposed next to the joining layer;
- a second substrate being disposed next to the second side and providing electrical circuit and a conductor;
- and
- at least an illuminant component being provided beside periphery of the guide light layer to connect with the electrical circuit.
