摘要： A touch pad includes a first substrate, a second substrate and a joining layer. The joining layer joins the first substrate and the second substrate together. The first substrate provides a refection layer at a lateral side or both sides thereof with at least a light emitting component being disposed at the periphery of said reflection layer. The second substrate provides an electrical circuit with a first conductor to connect with the light emitting component. The reflection layer is provided with a size less than said first substrate and has an upper side to adhere said first substrate so as to be fixed in said joining layer. the electrical circuit is capable of determining if the touch pad is touched with an object by means of receiving a change of coupling capacity of a sensing locus and capable of controlling luminosity of said light emitting component.
