A comparing unit compares a predetermined first reference voltage and an output voltage which is proportional to a current applied to the light emitting element. A controller compares a comparison voltage output, which is a comparison result of the comparing unit and a predetermined second reference voltage, in order to control the switch to be switched on and off. Accordingly, the present invention provides a display apparatus and control method which precisely controls a size of a current applied to a light emitting element.
