1. A display apparatus, comprising:

  • a light emitting element;

    a power line that supplies a current to the light emitting element;

    a capacitor that stores a charge;

    a driver that flows the current through the power line to the light emitting element, the current corresponding to the charge stored in the capacitor;

    a memory that stores a plurality of trap levels in association with a plurality of use durations of the light emitting element, each of the plurality of trap levels corresponding to an energy level generated in the light emitting element as the current is supplied to the light emitting element;

    a first obtainer configured to determine one of the plurality of use durations of the light emitting element; and

    a controller configured to read, from the memory, one of the plurality of trap levels associated with the one of the plurality of use durations of the light emitting element, and to remove a charge generated in the light emitting element by application of a reverse bias voltage to the light emitting element, the reverse bias voltage being associated with the one of the plurality of trap levels read from the memory,wherein, as the one of the plurality of use durations of the light emitting element increases, a level of the reverse bias voltage increases.
