Kind Code:
A1
Abstract:
A display device, according to one embodiment, comprises: a plurality of display modules; and at least one power supply device for supplying power to the plurality of display modules. The at least one power supply device comprises: a rectifier circuit which converts AC power to DC power; a plurality of reference converters which each transform the DC power to a first voltage and output the first voltage between a reference ground node and a reference output node; a plurality of floating converters which have a plurality of floating output nodes connected in parallel, and which each transform the DC power to the first voltage and output the first voltage between the floating output node and a floating ground node connected to the reference output node; and a plurality of load share circuits which are respectively provided to the plurality of floating output nodes and are mutually connected so that respective output currents of the plurality of floating converters are equalized.
