Abstract: A variable color complementary display device includes a plurality of display areas arranged in a pattern for selectively exhibiting a plurality of display units. Each display area includes a plurality of pairs of light emitting diodes for emitting, when forwardly biased, light signals of respective primary colors and a device for combining the light signals in the display area to obtain a light signal of a composite color. Each pair includes a first light emitting diode and a second light emitting diode, both of the same color, connected in an anti-parallel fashion such that their polarities are opposite. A device is provided for selectively forwardly biasing the first light emitting diodes, for illuminating certain of the display areas in a display color. The second light emitting diodes in the remaining display areas are automatically illuminated in a complementary color.

Abstract: A variable color display device comprises a plurality of display areas arranged in a 7-segment font. Each display area includes at least two light emitting diodes for emitting upon activation light signals of respectively different primary colors and means for blending the light signals within the display area to obtain a composite light signal of a composite color. The light emitting diodes are selectively activated by pulses of substantially constant amplitude to display desired characters. Color control selectively controls the durations of the pulses to control the portions of the primary colors, to thereby control the color of the composite light signal.
