Abstract : Previous electroluminescent cell pulse-response data have been collected using equilibrium values for a constant repetition rate pulse train. The present investigation concerns the response of El cells to individual rectangular pulses. Measurements of light output were made on each successive pulse, starting with the first pulse, until the equilibrium values were reached. The variation of this response with changes in pulse excitation rise and fall times has been explored, and the double light output peak occurrence caused by selected rectangular pulses has been observed and measured for peak level and rate of decay. The visibility of the light output for initial and successive pulses has been evaluated under constant ambient conditions. The above aspects of electroluminescent response have been correlated for several El cell designs with dissimilar phosphors, widely different cell thicknesses, and binder matrix materials of plastic or soft glass.
