Abstract

A drive circuit is provided for an OLED in a pixel array. The circuit includes input voltage signal receiving means. Output voltage signal generating means are operably connected to the pixel diode. Means are provided for processing the input voltage signal to replicate the inverse IV characteristic of the pixel diode, to form the output voltage signal.
