摘要: 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.

摘要: A multicolor optical device having at least three optically stable states includes a plurality of pairs of associated light sensors and light sources for emitting light of respectively different colors when activated. Each light source is divided by an opaque wall into a first light emitting portion and a second light emitting portion. The light signals from the first light emitting portions of all light sources are blended to obtain a composite light signal of a variable color. Separate optical feedbacks are established between the second light emitting portions and light sensors in pairs tending to stabilize the light sources in their conditions to thereby maintain the color of the composite light signal.
