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.
