Abstract
A character display in which failures are evident. Selected segments of a seven-segment LCD are activated by control signals supplied through selected fore plane and back plane traces. By coupling specific ones of the fore plane and back plane control signals to selected segments, any failure in the control signal or circuitry providing the signal to the segments of the display character becomes immediately evident to an operator when the character represented by the display is not one of a predefined set of characters.
