ABSTRACT:
A color printing system including thin film electroluminescent (TFEL) edge emitter devices and an electronic interface for driving the TFEL devices. The TFEL edge emitter devices form a multi-color TFEL edge emitter structure operable for emitting a plurality of different colors of light onto a media. The electronic interface receives gray scale data for pixels and converts it into a serial data stream used to drive pixels in the TFEL edge emitter structure. The electronic interface further includes a compensation memory for compensating for pixel variations in the TFEL structure. The compensation memory can be periodically recalibrated "in place" during the life of the printing apparatus.
