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.
