Abstract:
A touch sensor includes a controller to detect a touch on a screen. The controller includes a voltage analyzer and a calculator. The voltage analyzer measures an output voltage of a sensing electrode of a touch sensor. The calculator calculates a capacitance between the sensing electrode and a driving electrode. The calculator calculates the capacitance based on a voltage matrix and the output voltage for one or more time periods. The voltage matrix is based on a code matrix of a plurality of code matrices.
