PURPOSE: A video display device is provided to control a white balance by controlling an analog voltage level outputted from a digital-to-analog converter. CONSTITUTION: A digital-to-analog converter(321~323) outputs an analog voltage corresponding to a received digital color signal. A panel(330) operates a color reproduction after receiving a voltage. A controller(400) controls the level of the analog voltage. The controller controls a white balance. The controller sets the offset and the gain of an output voltage corresponding to the digital color signal.
