<p>PROBLEM TO BE SOLVED: To easily reduce an image display system that makes a number of modules show a diversified image or a moving image. SOLUTION: The dual voltage power apparatus comprises a dual voltage power supply apparatus, that biases an anode voltage to a load comprising a plurality of paired light-emitting diodes in the forward direction, and puts bias on a cathode voltage in the reverse direction, and a multicolor emission diode driver for controlling the operation of the dual voltage power supply section for supplying an anode and/or cathode voltage to a load, which is outputted by a single module.</p> |
