Blue laser diodes
To generate the three primary colours in a 1DLP® laser phosphor projector, the laser diode shines blue laser light onto a phosphor wheel. The wheel creates yellow and green light, while blue laser light passes through an opening in the phosphor wheel.
The projector then sends the yellow and green light through a colour wheel to generate red or further enhance green, while the blue laser light passes through a diffusion window in the colour wheel.
These red, green, yellow and blue colours are then directed onto an imaging surface, such as a DLP chip which directs the light through a lens and onto the projection screen.
Typical laser phosphor
Employs blue laser diodes shining
onto a phosphor wheel.
Laser phosphor hybrid
Same as a typical laser phosphor projector
but adds a red LED light source to boost
the red colour component.
Laser phosphor with red laser
Similar to a laser hybrid, but employs a red laser
diode instead of an LED to produce better
overall saturation and realistic colours.
