Zusammenfassung:A source driver may include: a transmission line configured to transmit an output signal of a sample and hold circuit which stores pixel information of an organic light emitting diode (OLED) cell; an amplifier is formed a first offset voltage at an input terminal by a parasitic capacitor of the transmission line; and an offset voltage storage unit configured to store the first offset voltage outputted from the amplifier as a second offset voltage while the transmission of the output signal of the sample and hold circuit through the transmission line is turned off, and offset the first offset voltage by providing the second offset voltage to the input terminal of the amplifier when the output signal of the sample and hold circuit is transmitted through the transmission line.
