Abstract:
A display system comprising:a plurality of adjacent variable color digital display elements, each said display element including a plurality of display segments and a decimal point segment for selectively exhibiting a plurality of strings of digits with a decimal point, each said display element including a color control input for illuminating it in a color in accordance with a color control signal, the color control inputs of all said display elements being interconnected;decoder means having a plurality of inputs for receiving input codes defining a string of digits with or without a decimal point, a plurality of decoder outputs for developing drive signals for selectively energizing said display segments, and a plurality of decimal point outputs for developing drive signals for energizing a certain of said decimal point segments, if the decimal point is present in said string of digits;means responsive to said decoder outputs and to said decimal point outputs for exhibiting on said display means the string of digits which may include a decimal point;means for interrogating said decimal point outputs to determine whether there is a decimal point in the string of digits and for developing an output signal accordingly; andcolor control means for coupling said output signal to the interconnected color control inputs for illuminating all digits in the string in a first color when said decimal point was detected, and in a second color when said decimal point was not detected.
