ABSTRACT:
A display device having a plurality of power supplies and a method for controlling the same are provided. A large-screen display device can be embodied using a plurality of small-capacity power supplies. The operating states of the power supplies are monitored so that the user can immediately deal with abnormal operations of the power supplies. The display device includes a Plasma Display Panel (PDP) module including a plurality of boards that are grouped into at least two groups, at least two power supplies corresponding to the at least two groups and supplying power to the grouped boards, and a controller. Upon receiving a power-on command, the controller controls the at least two power supplies to be activated and controls them to supply power to the grouped boards in the PDP module.
