Abstract
A touch controlling apparatus to be coupled to a touch sensor array is disclosed. The apparatus comprises a memory circuit and a controlling circuit. The memory circuit is used for recording different calibration ratios associated with different process variations. The controlling circuit is coupled to the memory circuit, and is used for calibrating or adjusting sensitivities of a plurality of cells by respectively using the different calibration ratios to calibrate or adjust sensed capacitance changes of the plurality of cells to generate and output resultant capacitance changes of the plurality of cells.
