Abstract
A method of compensated touch data values disclosed herein includes acquiring touch data values about a dead sensing zone of a touch screen, and determining a peak value of those touch data values. Then, a new peak value is calculated as a function of an average of the peak value and another value of the touch data value, and a sharpness value for the dead sensing zone is generated if a second highest value of the touch data values is less than the new peak value. Thereafter, compensated touch data values are generated for the dead sensing zone if the second highest value is greater than the new peak value.
