Abstract:
1. A method for driving an image display apparatus including a rear plate including electron-emitting devices, a face plate including an anode electrode, a voltage applying unit configured to apply a voltage to the anode electrode, and a switching unit configured to switch between a display state of displaying an image and a non-display state of displaying no image, the method comprising: after a non-display time exceeds a referenced first time, and if the switching unit sets the non-display state before a display time exceeds a reference second time, after the non-display time exceeds a time shorter than the first time in accordance with the display time, the voltage applying unit applies, to the anode electrode, a second voltage lower than a first voltage to be applied in the display state, to enable the electron-emitting devices to emit electrons, wherein the non-display time is a time when the switching unit allows the non-display state to continue, and the display time is a time when the switching unit allows the display state to continue.
