What is laser phosphor?

Laser phosphor uses dedicated laser diodes that are filtered through a phosphor wheel and color wheel to produce accurate DCI-P3 color patterns on screen. The lasers vary based on source. For our purposes on this site, we will refer to RB-laser phosphor where red and blue lasers are filtered through a yellow phosphor wheel to complete the color spectrum. The light produced from here is then separated using dichroic coatings to create green light. Direct red and blue light from the lasers directly pass through a diffusion segment in the phosphor wheel. The separated red, green, and blue colors are then sent to an imaging surface, which then sends the light through a lens onto the screen. With instant on/off capabilities and long operational life, laser phosphor projection offers minimal maintenance and a low cost of ownership.

Laser phosphor variants

Employs blue laser diodes shining through a phosphor wheel

Same as a typical laser phosphor projector, but adds a red LED light source to boost the red color component

Similar to a laser hybrid but employs a red laser diode instead of an LED to produce better overall saturation and realistic color. This approach forms the basis of Christie BoldColor™ technology.

Why choose laser phosphor?

Laser phosphor projection offers many benefits:

Saves time and money – solid state illumination eliminates the need to replace lamps and filters, reduces consumables and waste, effectively lowers maintenance by reducing downtime, therefore lowering your total cost of ownership
Long operational life – 20,000 hours to 50% brightness
24/7 operation for demanding applications
Reduced energy consumption
Instant on/off capabilities

Ideal for high-use applications

Boardrooms

Classrooms

Auditoriums

Retail locations

Houses of worship

Location-based entertainment venues
