Abstract
There is provided a power supply for a light emitting diode display using a light emitting diode as a backlight unit that unites a DC power supply provided from outside the light emitting diode display and a driving power supply provided inside the light emitting diode display. A power supply of a light emitting diode display according to an aspect of the invention may include: a power conversion unit converting commercial AC power into at least one driving power having a predetermined voltage level; and a backlight driving unit generating a backlight driving signal using the driving power from the power conversion unit, wherein the power conversion unit and the backlight driving unit are mounted onto one printed circuit board.
