Abstract: A light emitting diode display device includes a variable color display area, for exhibiting a selective display unit, substantially surrounded by a variable color background area. The light emitting diodes in the display area are commonly coupled to a plurality of display buses, in accordance with their display colors. Similarly, the light emitting diodes in the background area are commonly coupled to a plurality of background buses, in accordance with their background colors. A display color control is provided for selectively activating the display buses, for illuminating a desired display unit in a selective color. A background color control is further provided for activating the background buses, for illuminating the background area in a uniform color different from the color of the display area.
