Abstract:
A display apparatus is provided which optimally restores decreased luminance and extends a life of a light emitting element. The display apparatus includes a memory that stores a plurality of trap levels in association with a plurality of use durations of the light emitting element. An obtainer determines one of the plurality of use durations of the light emitting element. A controller reads, from the memory, one of the plurality of trap levels associated with the one of the plurality of use durations, and removes a charge from the light emitting element by application of a reverse bias voltage having a level associated with the one of the plurality of trap levels. The controller changes the level of the reverse bias voltage which is applied to the light emitting element so that as the one of the plurality of use durations increases, the level of the reverse bias voltage increases.
