Touch-screen panel with multiple sense units and related methods

摘要

This document discloses, systems, methods, and articles of manufacture, related to position sensors and uses of such sensors. Multiple panels can be arranged in close proximity to one another and one or more sense or drives lines associated with each respective panel can be associated with a control circuit of the other adjacent panel.

1. A panel for a touch position sensor, comprising:
a first panel region including a plurality of first touch sense channels for communication with a first sense unit; and a second panel region adjacent to the first panel region, the second panel region including a plurality of second touch sense channels for communication with a second sense unit, wherein: at least one touch sense channel associated with the first panel region and at least one touch sense channel associated with the second panel region are configured for communication with each of the first sense unit and the second sense unit; a processor operable, when the at least one touch sense channel associated with the first panel region and the at least one touch sense channel associated with the second panel region detect a touch in different sensed positions, to select one of the different sensed positions as a position of the touch; and wherein the processor is further operable to select said one of the different sensed positions as the position of the touch by determining which of the touch sense channels that detect the touch is located farthest from an edge of a channel set defined by the touch sense channels that are configured for communication with each of the first sense unit and the second sense unit.
