    摘要: An electroluminescent display having reversible polarity and a method for reducing latent images in the electroluminescent panel is provided. The electroluminescent display includes a waveform generator for supplying voltage pulses to illuminate pixels within the electroluminescent panel. The electroluminescent display according to the invention periodically reverses the polarity of the voltage pulses to reduce latent images in the electroluminescent panel. The electroluminescent display preferably utilizes an asymmetrical drive scheme to provide a brighter electroluminescent display.
