摘要： A touch location on a capacitive touchscreen system is identified by receiving signals in response to a touch from electronic channels connected to one electrode or to a group of semi-adjacent electrodes provided on a substrate. Adjacent ones of the electrodes have substantially triangular shapes that alternate between a first and second orientation to form an interleaved arrangement such that the touch generates a signal cluster comprising the signals generated from a series of adjacent electronic channels. Weights with at least two different numerical values are applied to the signals from the series of adjacent electronic channels. The at least two different numerical values are based on levels of the signals. A location of the touch on the substrate is determined based on the weighted signals.

摘要： A touchscreen system (1 10) comprises a touch area (156). At least one transmitter (152,154) is positioned proximate to outer edges (157) of the touch area for transmitting first beams in a first direction. At least one beam splitter (162,164) is positioned proximate to the outer edges of the touch area for splitting the first beams into at least second and third beams that travel through the touch area in at least second and third directions, respectively. The at least one beam splitter comprises a plurality of deflecting elements (169). Receivers (158,160) are positioned proximate to the outer edges of the touch area for receiving the at least second and third beams.

摘要： A projected capacitive touch screen (300) is provided that comprises a substrate (302) and electrodes (310-326). The substrate defines an active touch zone (304) surrounded by edges (306-309). The active touch zone includes a central active zone (399) and an acceleration zone (391, 393, 395, 397) that is located proximate to, and extends along, at least one of the edges. The electrodes are provided on the substrate and are organized into first and second sets of electrodes that are contained within a common plane on the substrate. The first set of electrodes (310-317) is interlaced with the second set of electrodes (320-326) in a non-overlapping pattern on the substrate. At least a subset of the electrodes each has an apex and a base and a non-uniform triangular shape that extends along a longitudinal axis between the apex and the base. The subset of the electrodes is located such that at least a portion of the non-uniform triangular shape is located within the acceleration zone. The non-uniform triangular shape (370, 376, 382, 386, 390) may be formed in part by varying an electrode width more rapidly near a perimeter of the active touch zone than the variation of the electrode width near a center of the active touch zone. The non-uniform triangular shape and non-overlapping pattern provide edge acceleration to compensate for signal loss when a portion of a finger contact area moves beyond the edge outside of the active touch zone. The non-uniform triangular shape may include a first pitch (346) proximate to the base and a second pitch (350) proximate to the apex. The pitch represents a rate of change in a width of the electrode per unit of distance along the longitudinal axis of the electrode.
