ABSTRACT:
A variable color display systems sequentially exhibits digital values in a color in accordance with the relation of the presently exhibited digital value to a past digital value. A memory, controlled by a timer, is provided for storing data representing the past digital value. A comparator compares the presently exhibited digital value with the data stored in the memory and develops a comparison signal accordingly, which is then used to control the color of the presently exhibited digital value.
