Abstract:
In a display device including a driver that drives load lines in an electro-optical panel through capacitor charge redistribution, load capacitance among the load lines of the electro-optical panel differs depending on parasitic capacitance of a board on which the load lines are mounted, the type of the panel, and so on, and the accuracy of driving voltages drops due to such variations. The driver is provided with a adjusting capacitance group that corrects variation in load capacitance, and by adjusting a driving capacitance on the driver side, a ratio with the load capacitance is increased and accuracy of a post-driving potential is increased.
