ABSTRACT:
An electroluminescent display panel formed of phosphor and dielectric layers sandwiched between opposing mutually intersecting arrays of drive electrodes, has the thickness of the phosphor layer set to a value which provides minimum power consumption, for a given level of display brightness. This is achieved by determining a value of capacitance per unit area of the panel which results in a maximum allowable value of time being required to charge each display element, then determining a value of phosphor layer thickness providing minimum power consumption, using the latter value of capacitance and the known value of light emission efficiency of the display.
