Abstract: A touch sensor of multi-driving scheme includes a touch panel including input lines and output lines, the touch panel causes a change in mutual capacitance in response to touch. Processing circuitry generates transmission signals to the input lines as a result of an encoding operation on a first matrix having an inverse matrix, each of the transmission signals has a first polarity or a second polarity opposite in phase to the first polarity; outputs the transmission signals in an unbalanced period when the sum of phases of the transmission signals is greater than 0; receives receiving signals through the output lines; and decodes the receiving signals based on the first matrix, the receiving signals generated by the change in the mutual capacitance in response to the touch.

Abstract: A touch processor circuit includes a capacitance-to-voltage converter and an analog-to-digital converter. The capacitance-to-voltage converter converts an input signal transmitted from a touch sensor into a conversion signal corresponding to a capacitance of the touch sensor. The analog-to-digital converter digitizes the conversion signal transmitted from the capacitance-to-voltage converter and generates a digital value. The analog-to-digital converter includes a first converter, a second converter, and a combination logic circuit. The first converter calculates upper bits of the digital value based on the conversion signal during a first time period. The second converter calculates lower bits of the digital value based on a residue component signal transmitted from the first converter during a second time period. The combination logic circuit combines the upper bits and the lower bits and generates the digital value.
