Abstract
Meshed touchscreen pattern. A conductive pattern implemented within a touchscreen (e.g., using indium tin oxide (ITO) such as may be deposited on a substrate composed of polyester or some other material) provides paths for signals traveling through the touchscreen. By monitoring these signal in accordance with some means (e.g., cross point detection, zone detection, etc.) an estimate may be made as to a location of user'"'"'s interaction with the touchscreen (e.g., finger or stylus touching of the touchscreen). The conductive pattern includes a number of conductors aligned in various directions (e.g., row and column conductors) across the touchscreen, and they are separated by a dielectric layer (e.g., air, SiO2, or any other desirable dielectric layer). The conductors include a great deal of interlacing and meshing as achieved by spurs, extensions, and/or protrusions (e.g., of any desired shape) extending from one conductor into an adjacent conductor within the conductive pattern.
