1. A user interface comprising:
- a touch surface substrate having a front side and a rear side, said touch surface substrate including a light transmissive portion and defining an operative touch surface;
a circuit carrier having a front side and a rear side, said front side of said circuit carrier associated with said rear side of said touch surface substrate, said circuit carrier defining an aperture therein, said aperture at least partially in registration with said light transmissive portion of said touch surface substrate;
a sensor comprising a first sensing electrode disposed upon said circuit carrier proximate said aperture, said sensor at least partially in registration with said operative touch surface; and
a selectively illuminated light source associated with said rear side of said circuit carrier such that light emanating from said light source is visible from said front side of said touch surface substrate at said light transmissive portion of said touch surface substrate;
with no intervening structure between said rear surface of said circuit carrier and said rear surface of said touch surface substrate through at least a portion of said aperture.

Abstract
A user interface includes a touch surface substrate, a graphic layer, a touch sensor disposed on a circuit carrier associated with the rear side of the touch surface substrate, and a light source associated with the rear side of the circuit carrier. The circuit carrier defines an aperture through which light emanating from the light source can pass. This light also passes through the graphic layer and is visible at the front side of the touch surface substrate.
