Abstract: The structure disclosed reduces the number of bonding pads and interconnect traces in the opaque portion of a single-layer touch panel. By sharing and multiplexing the bonding pads in the opaque portion of panel, half as many pads are needed to provide the interconnection bases for the traces in the opaque portion of the panel that extend to the control electronics subsystem. Further, by connecting the ground plane structures that are adjacent to each TCO column electrode, all ground planes are made part of a common ground-plane electrode. That single common ground-plane electrode can be connected to the appropriate trace and control electronic subsystem using a single pad, rather than several individual ground-plane pads.

Abstract: A capacitance sensing apparatus includes capacitance sensor elements covered by a layer of material. The layer of material has an uneven effect on a measure of capacitance induced in the capacitance sensor elements when an object is in proximity to a sensing surface. For example, the layer of material may have a non-uniform thickness, or a property of the material may be non-uniform across the layer. The capacitance sensor elements are dimensioned to compensate for the effect.

Abstract: One type of capacitive sensing apparatus has a sensing element that includes a first portion and a second portion adjacent opposite edges of a sensing region. Signals from the first and second portions are combined. Another type of apparatus includes: a first sensing element including first and second portions; a second sensing element including third and fourth portions; and a third sensing element including fifth and sixth portions. The first, third and fifth portions form a first pattern, and the second, fourth and sixth portions form a second pattern. The patterns are bilaterally symmetrical about a median of a sensing region. In another type of apparatus, an electrical conductor coupled to a first sensing element passes through a gap in a second sensing element. An electrical conductor coupled to the second sensing element is dimensioned such that a capacitive coupling to the second sensing element is compensated for the gap.
