Abstract
A display apparatus, that can prevent thermal destruction and burning with a simple structure, has been disclosed. In the apparatus it is judged that there is possibility of a pattern, whose area with high brightness is small, being displayed frequently, when a state in which the total light emission pulse number remains large occurs with high frequency, and if such a state is detected, the total light emission pulse number (sustain frequency) is reduced to prevent the thermal destruction and burning.
