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