Abstract
A controller for controlling the intensity of an electroluminescent display is disclosed. The controller controls a number of skipped cycles in a cycle set of an applied waveform to the electroluminescent display to vary the average duty cycle, and thereby adjust the intensity of the electroluminescent display. The controller is further configured to adjust the intensity of individual channels within the electroluminescent display to provide compensation for display aging, color variation, as well as for varying intensity for various operating modes.
