Touch sensor
First Claim
1. A touch sensor comprising:
- a substrate having a first surface and a second surface opposite the first surface;
a transparent conductive layer disposed on the second surface of the substrate, wherein the transparent conductive layer is disposed in a pattern so that the transparent conductive layer comprises a plurality of discrete conductive pads, the discrete conductive pads substantially overlay the entire substrate and are conductively connected to at least one connecting region of the substrate via respective conductive traces, and wherein the plurality of discrete conductive pads are formed at a first touch area and a second touch area, wherein the first touch area is formed on sides of the second touch area, and the size of said discrete conductive pads at the first touch area is substantially different from the size of said pads at the second touch area, and wherein the second touch area comprises only one first pad of the pads and the first touch area comprises a plurality of second pads of the pads, and wherein the second pads are arranged on sides of the first pad; and
wherein the discrete conductive pads at the first touch area are associated with respective buttons of a display device disposed at the substrate, such that the user touches or approaches the substrate and pads at the first touch area in response to the displayed buttons as viewed by the user through the pads and substrate.

Abstract
A touch sensor includes a substrate having a first surface and a second surface opposite the first surface, and a transparent conductive layer disposed on the second surface of the substrate. The transparent conductive layer is disposed in a pattern so that the transparent conductive layer includes a plurality of discrete conductive pads, with the pads being conductively connected to at least one connecting region of the substrate via respective conductive traces. The pads are associated with respective buttons of a display device disposed at the substrate, such that the user may touch or approach the substrate and pads at selected areas in response to the displayed buttons as viewed by the user through the pads and substrate.
