2137803 9401855 PCTABScor01 A power supply for providing a symmetric drive for an AC electroluminescent (EL) display panel includes a single power supply which provides two voltage signal values of opposite polarity Vpos, Vneg to the panel's row drivers. The supply also corrects the difference between the two voltage signal values Vpos, Vneg as a function of the difference between the maximum column driver voltage value Vcol and its nominal value to reduce latent images on the display panel. By utilizing a single switching regulator to generate the opposite polarity row voltages Vpos, Vneg the circuit complexity and cost associated with providing a symmetric drive for an EL panel is reduced.
