PICTURE DISPLAY DEVICE AND ITS DRIVING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a new driving method performing a source line inversion driving method and a dot inversion driving method when plural source lines are driven with a D/A converting circuit in the source signal line driving circuit of an active matrix type picture display device coping with a digital video signal input. SOLUTION: In a first driving method, two systems of gradient power source lines are supplied to a source signal line driving circuit in order to obtain outputs whose polarities are different from D/A converting circuits and respective D/A converting circuits are provided with switches switching connection with the two systems of gradient power source lines and the source line inversion drive and the dot inversion drive are performed by switching the gradient power source line which is to be connected to the respective D/A converting circuits by a control signal to be inputted to the switches.
