The magnitude of the first voltage has a first level and a second level that is different from the first level, and the magnitude of the second voltage is constant. A time period for maintaining the first voltage at the second level in a interval for reading the sensing signal is at least 1H, and the sensing signal is generated while maintaining the first voltage at the second level. Accordingly, a time for outputting the sensing signal is increased and sensitivity of the sensing unit is improved, thereby increasing reliability of the sensing signal.
