Zusammenfassung:A sample and hold circuit may include: a main sample and hold circuit configured to sample and hold pixel information of an organic light emitting diode (OLED) cell, and output a first output signal; and a dummy sample and hold circuit configured to sample and hold a reference voltage in synchronization with the main sample and hold circuit, and output a second output signal for offsetting a switching noise signal contained in the first output signal.
