ABSTRACT:
Current flowing through a plurality of light emission diodes is individually controlled, thereby an image with a desired color is displayed according to color lights emitted from the light emission diodes. A sum of current flowing through the light emission diodes is maintained at a predetermined current, thereby brightness of the image is maintained at a predetermined brightness.
