发明名称 Image display device and driving method thereof
摘要 A novel driving method is provided in which source line inverting drive or dot inverting drive is performed for a case of driving a plurality of source lines by one D/A converter circuit in a source signal line driver circuit of an active matrix image display drive that corresponds to digital image signal input. In a first driving method of the present invention, two systems of grey-scale electric power supply lines are supplied to a source signal line driver circuit in order to obtain output having differing polarities from a D/A converter circuit, switches for connecting to the two systems of grey-scale electric power supply lines are prepared in each D/A converter circuit, the grey-scale electric power supply lines connected to each D/A converter circuit are switched in accordance with a control signal input to the switches, and source line inverting drive or dot inverting drive are performed.
