Abstract
An image display apparatus includes a display panel having an electron source, an acceleration electrode for accelerating electrons emitted from the electron source and phosphors for emitting light by collision of electrons accelerated by the acceleration electrode, and a detector for detecting a current flowing through the acceleration electrode during a non-display period. In addition, a controller is provided to decrease the luminance level, stop display driving or transmit warning information when the current detected becomes more than a predetermined value.
