Patent ID: 6972741

Claim:
An image display apparatus comprising: a display panel for displaying an image by irradiating a fluorescent substrate with electrons from an electron source; an acceleration potential supply circuit for supplying to said display panel an acceleration potential for accelerating electrons from the electron source; a scanning circuit for supplying a scanning signal to said display panel; a modulation circuit for supplying a modulation signal to said display panel; and a control circuit for outputting a signal for stopping output of the signal from said scanning circuit and/or said modulation circuit to said display panel, wherein supply of power to said scanning circuit and/or said modulation circuit is stopped in a state in which the output of the signal from said scanning circuit and/or said modulation circuit to said display panel is stopped by said signal for stopping in turning off a power source while an image based on a video signal is displayed by outputting a signal from said scanning circuit and/or said modulation circuit to said display panel.
