ABSTRACT:
SUMMARY OF THE INVENTION
It is the principal object of this invention to provide an improved multicolor display device.
It is another object of the invention to provide a multi-element multicolor display system using two primary color LEDs.
It is still another object of the invention to provide a multi-element multicolor display system using three primary color LEDs.
It is still another object of the invention to provide a multi-element multicolor display system having a plurality of color control inputs which are respectively interconnected.
It is still another object of the invention to provide a multicolor display device having an enable control input.
It is still another object of the invention to provide a multi-element multicolor display system in which the color control signals may be presented to all display elements simultaneously, and the enable control signal determines which display element illuminates.
Other objects of the invention will be obvious from the appended drawings and their description.
In summary, a multi-element display system of the invention includes a plurality of multicolor light emitting diode display elements, each display element having a plurality of color control inputs and an enable input. The like color control inputs of all display elements are interconnected.
The invention resides in commonly presenting the color control signals to the interconnected color control inputs of all display elements, and in individually controlling the display elements by their enable inputs, either to extinguish them or to illuminate them in a color in accordance with the color control signals.
