Abstract:
Disclosed herein is a touch screen controller including input circuitry operating a touch screen, and processing circuitry cooperating with the input circuitry to acquire mutual touch data and self touch data from the touch screen, sum values of the mutual touch data to produce mutual sums, normalize the mutual sums and the self touch data, and calculate differences between the normalized self touch data and the normalized mutual sums. The touch screen controller enters into a floating mode if a largest difference that is positive is greater than a positive difference threshold and if a smallest difference value that is negative is less than a negative difference threshold, but enters a non-floating mode if the largest difference that is positive is less than the positive difference threshold or if the smallest difference value that is negative is less than the negative difference threshold.

Claim (Index 10):
A method, comprising:\n determining whether a ground of a touch screen device and a ground of an object touching a touch screen of the touch screen device are mismatched by:\n acquiring mutual touch data and self touch data from the touch screen, the mutual touch data being arranged into multiple rows and multiple columns, the self touch data being arranged into a single row and a single column; \n discarding self touch data values that are less than a first threshold; \n discarding mutual touch data values that are outside of an area defined by those self touch data values that are greater than the first threshold; \n discarding mutual touch data values that are less than a second threshold; \n summing remaining mutual touch data values in each column to produce mutual touch column sums; \n summing remaining mutual touch data values in each row to produce mutual touch row sums; \n normalizing remaining self touch data values, the mutual touch column sums, and the mutual touch row sums; \n calculating differences between the single row of normalized self touch data and the normalized mutual touch column sums; \n calculating differences between the single column of normalized self touch data and the normalized mutual touch row sums; \n determining a mismatch when a largest difference is greater than a positive threshold and when a smallest mutual difference is less than a negative threshold; and \n determining a lack of mismatch when the largest difference is less than the positive threshold or when the smallest mutual difference is greater than the negative threshold; \n based on determination of mismatch, switching touch sensing of the touch screen device into floating mode; and based on determination of a lack of mismatch, switching touch sensing of the touch screen device into normal mode.
