16 DLP Laser system design considerations
Laser phosphor light source (typically with RGB color wheel) Color wheel motor operation is tied to DMD control (duty cycle fixed to RGB segment sizes) Special attention should be given to optical and thermal system design to ensure optimal size and cooling

17 Laser TV optical engine considerations
