  • 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.
