4.4 Illumination Type

DLP technology can be used with any illumination type. Lamps, LEDs, and laser illumination are all potential options when designing optical modules with DLP chips. Currently, most DLP Pico projection optical modules use RGB LED illumination due to their small size and high brightness efficiency. DLP Pico projection systems also use laser illumination to achieve higher brightness levels and smaller optical designs. Optical module manufacturers can help choose an appropriate illumination type based on the system requirements.
