Abstract
The voltage-luminous intensity transfer function for DC electroluminescence (DCEL) ZnS:Mn,Cu powder display panels has been determined by impulse response testing using crosscorrelation techniques. The investigation has revealed a signature characteristic featuring evidence of an internal feedback mechanism which is a function of the mean voltage causing luminescence. It has further shown that the time constant of the system is also a function of the mean voltage. Fourier transforms of the domain data indicate a second-order mechanism dominating the transfer function
