ABSTRACT:
An electrical display and method in which the least significant digit is moved or scrolled in mechanical counter fashion are disclosed. Only the least significant digit is scrolled, and the more significant digits change instantaneously when an adjacent less significant digit changes between its highest and lowest values, unlike mechanical counters. The disclosed display and method include a rounding-off feature according to which the least significant digit is rounded off when the input signal variable is unchanging and displayed in alignment with the display of the more significant digits.
