3. Product Overview The projector consists of DLP projector controller, Lamp controller, Power supply system, and System cooling controller. The DLP controller captures digital PC data and video data and then converts them into the DMD display device. The Lamp controller dominates the lamp’s power and synchronizes its frequency with color display sequence. The Power supply unit controls the AC line power factor and converts primary voltage to secondary low voltages for digital board. The System cooling controller drives the airflow to quench the lamp’s heat and electrical component’s heat.
