Abstract: Compensation of pixels that generate erroneous readings (so-called “negative pixels”), produced when multiple touch events are generated by the same poorly grounded object on a touch sensor panel is disclosed. To minimize negative pixels, a thicker cover material and/or a lower dielectric constant can be used. Alternatively, narrower drive and sense lines can be employed. To compensate for negative pixels, a predicted negative pixel value can be computed as an indicator of pixels that are likely to be distorted.

The predicted negative pixel value is added to the measured touch output value for the pixel to compensate for artificially negative readings.
