Abstract: A video display interface adapted for use with D.C. electroluminescent display panels and constant current display drivers is disclosed. The video display interface receives serial video data at a frame rate of 60 Hz, converts it into eight bit words and stores it in a double-buffered video memory according to a memory map having ten sections corresponding to ten logical display sections. The video display interface reads stored video data out of the memory map, converts it to ten bit parallel output words and outputs the ten bit words to display drivers to drive multiple sections of the display simultaneously at an output frame rate of 240 Hz. The video display interface also generates constant current and pre-charge control signals that are used by the display drivers to generate constant current and pre-charge signals for driving the display.
