Abstract
In an image display apparatus and image display method suppress the degradation of display function and the shortening of service life due to long-term use, measurement of a current value is carried out and the measured current value each time a certain time elapses is stored. The integrated value of the current is calculated, and a comparator compares the integrated value with a reference value stored in a storage section for determining whether or not the result is greater than a prescribed value. If the result is affirmed to differ by prescribed value, a recovery voltage is applied, and it is determined whether or not a recovery time has exceeded a stored recovery time. If the excedance of the recovery time is affirmed, the application of the recovery voltage is terminated. If a negation is given at the determination of the greater difference value, the flow is ended. If a negation is given at the determination of the recovery time, the recovery voltage is applied.
