摘要:
The invention is a structure and method for creating areas of non-conducting or isolated conducting surfaces within an area of conducting surfaces such that the capacitance of said conducting surface is reduced relative to a proximate, essentially parallel, conducting surface.
摘要:
The invention is a system for reducing finger-coupling capacitance of a touch-sensor panel such that finger-coupled noise signals do not overwhelm the sensing circuit and render the panel unable to detect the finger position.
摘要:
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.
