  • Patent number: 8237068
    Abstract: A touch-sensitive panel is described herein that includes a first sensor layer and a second sensor layer and at least one shield electrode integrated into the first sensor layer and/or the second sensor layer. The at least one shield electrode is operable to cancel parasitic capacitance between at least one sense electrode in the first sensor layer and at least one sense electrode in the second sensor layer. The integrated shield electrode(s) in the first sensor layer and/or the second sensor layer can be used in place of an additional shield layer to combat parasitic capacitance in the touch-sensitive panel, thereby reducing the cost and materials necessary to manufacture the touch-sensitive panel. A touch-screen display that includes such a touch-sensitive panel and a method of operating such a touch-sensitive panel are also described.

  • Patent number: 7875814
    Abstract: An electromagnetic digitizer having a sensor segment that includes a generally longitudinal network of conductive lines. Two or more conductive lines are coupled in parallel. To enhance sensitivity, the adjacent lines are interconnected along the longitudinal structure, using interconnections in the form of short lines, oriented at an angle. The sensor segments may be miniaturized, to facilitate integration into a display module using semiconductor fabrication processes. Various sensor array structures may be implemented using the sensor segment structures. The sensor array may include longitudinal sensor segments arranged in a parallel array. To further enhancing sensitivity of the sensor array, additional lines may be provided between adjacent longitudinal sensor segments. The sensor array may also include half loop (or U-shaped) sensor segments arranged in an overlapping parallel array, or full loop sensor segments arranged in an overlapping parallel array.

    Abstract: An untethered stylus is configured to cooperate with a location sensor. The location sensor is configured to generate a magnetic field comprising a number of frequencies and communicatively couple to the stylus. The stylus is configured to include a housing having a tip and a shield. An antenna arrangement, provided at the housing, includes a number of coil resonant circuits each tuned to a different frequency of the magnetic field. Each of the coil resonant circuits is configured to be energized in response to the magnetic field. The coil resonant circuits of the antenna arrangement may each include an inductive coil disposed about a ferrite rod in a spaced relationship. A connection couples the coil resonant circuits between the tip and shield of the housing to define separate channels for communicatively coupling the stylus tip and the location sensor.
