The elctro-optical characteristics of DC-EL panels under AC excitation has been improved by using inductance compensation in peripheral circuits. The brightness of the panels could be improved by a factor of three or more comparing with that without the compensation
uhder the same exciting oltages. For the same brightness level
the driving voltage of the panel with the inductance compensation could be lowered for more than 20 volts. Since the brightness of the panels varies with the excitaion frequency and the width of excitation pulss
it is possible to obtain frequency modulation or pulse-width modulation for alphanumeric or image displays.
