1.2 Illumination

DLP technology is compatible with all visible light illumination sources, such as HID lamps, RGB LEDs, direct laser, laser/LED hybrid, and laser-phosphor illumination. DLP Display projection optical modules use RGB LED illumination because of the compact size and high brightness efficiency, while laser phosphor illumination is used to achieve even higher brightness levels with compact optical designs. Additionally, direct laser illumination is employed to achieve wider color gamuts and higher contrast in an optical module.

Optical module manufacturers assist in choosing the appropriate illumination type based on system requirements. For more detailed information regarding light source illuminators and the impact on optical systems, refer to slides 31 - 45 of the DLP Optical Design Guidelines presentation.
