ABSTRACT:
A display device includes a display area, for exhibiting a display unit, substantially surrounded by a variable color background area, which includes a color control input for uniformly controlling its color. The variable color background area includes a plurality of multi-color light emitting diodes arranged in a pattern, which are coupled to the color control input for being illuminated in a selective uniform color in accordance with a color control signal.
