Abstract: Disclosed is a display apparatus capable of preventing and/or reducing overheating of driving switches due to a malfunction during varying of a driving voltage. The display apparatus includes: a light emitting diode; a power supply configured to apply a driving voltage to the light emitting diode; a driving switch configured to control the driving current of the light emitting diode; a voltage sensor configured to detect the driving voltage; and a driving controller configured to control the driving switch so that the driving current of the light emitting diode follows a current reference. The driving controller may be configured, based on the driving voltage detected by the voltage sensor being greater than a predetermined voltage, to decrease the current reference to decrease the driving current of the light emitting diode.
