Abstract : The objective of this study was to determine the applicability of high contrast to both the monostable and bistable class of electroluminescent (EL) displays. An experimental display environment simulating the conditions for a Command and Control display situation was established and subject response was recorded when numerics were displayed on both a high contrast and conventional electroluminescent display panel. Controls were placed on the experimental procedures to insure against any learning effects which might occur. A 'forces choise' instruction was imposed on the subjects, compelling them to guess, to reduce differences between subjects. The data were analyzed using two criteria, one statistically equivalent to perfect performance and the other requiring actually perfect performance. Results were compared and applied to the operational display environment.
