摘要： An electronic apparatus and method of controlling the electronic apparatus are provided, in which a power supply supplies a driving voltage to a system; and a controller sequentially outputs a control signal controlling a level of the driving voltage to the power supply until a level of a usage voltage corresponding to the driving voltage in the system becomes substantially identical to a predetermined reference level, if the level of the usage voltage is not substantially identical to the reference level. Accordingly, the electronic apparatus and control method thereof automatically adjusts a size of driving power supplied to respective parts of the electronic apparatus.

摘要： The present invention relates to a display apparatus comprising a light emitting element supplying light, and a switch to switch on and off power, which is supplied to the light emitting element. 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.
