ABSTRACT:
Provided is an image display apparatus including: a vacuum container having an electron source enclosed therein for displaying an image; an ion pump communicating with the vacuum container for discharging air therefrom and decreasing pressure therein; and a resistor connected in series with the ion pump with respect to a power supply for driving the ion pump. Even if internal resistance of the ion pump undergoes order-of-magnitude changes according to its operating state, current consumption can be suppressed and the ion pump can be driven efficiently.
