Abstract
A smart controller chip for controlling an active matrix display. Within the controller chip, circuitry for generating analog reference levels is incorporated alongside circuitry for generating digital timing and control signals. The combination of D/A analog circuitry and standard digital logic makes the controller uniquely suited for addressing all the panel control needs both for the normal digital functions but also for control of the analog aspects of the panel, like display gamma. The analog reference levels and the digital signals are made programmable using registers internal to the controller chip. The contents of these registers are programmed initially by digital values stored in an external PROM or in flash memory integrated into the controller chip. In addition, software in a host system is able to program these registers via an interface between the host system and the controller chip.
