CAPACITIVE LOAD DRIVING METHOD, CAPACITIVE LOAD DRIVING APPARATUS, AND LIQUID CRYSTAL DISPLAY APPARATUS

摘要

When the potential at an end of a capacitive load is switched from a first power supply potential to a second power supply potential or vice versa, it is connected to a predetermined midway potential point between the first and second power supply potentials for a predetermined time period. This can reduce the current during a charging or discharging, the variation in the power supply potential to the capacitive load, and the power consumption without providing any charge storage capacitor having a large capacitance.
