A display apparatus having a capacitive load (Cij), clamp circuits ( 103, 104 ) for clamping the potential of the capacitive load to high and low levels, power recovering circuits ( 103, 104 ) including coils for recovering power from the capacitive load and supplying the recovered power to the capacitive load, a display load rate determining part ( 111 ) for determining a display load rate, and a control part ( 112 ) is provided. When the determined display load rate is smaller than a first threshold value, the control part does not use the power recovering circuits but uses the clamp circuits to control the potential of the capacitive load. When the determined display load rate is larger than the first threshold value, the control part uses the power recovering circuits and clamp circuits to control the potential of the capacitive load.
