What is laser phosphor?

Laser illumination falls into 2 categories: laser phosphor and RGB pure laser. Although both are solid-state technologies that use laser diodes as the light sources, each processes light in a different way, and both offer a variety of benefits to the customer.

Here’s how it works:

• Laser phosphor exclusively uses blue laser diodes as the primary light source. Blue light from the laser diodes shines onto a yellow phosphor-coated spinning wheel exciting the phosphor-producing yellow light
• The yellow light is then separated using dichroic coatings to create red and green light, while the blue light component directly passes through a diffusion segment in the phosphor wheel
• The separated red, green, and blue colors are then sent to an imaging surface like a DLP^® chip, which then sends the light through a lens and onto the projection surface

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

Christie BoldColor^™ technology creates the color balance needed to accurately reproduce colorful visuals without sacrificing brightness.

BoldColor achieves this with blue and red laser diodes and specialized saturation software that produces enhanced color and saturation compared to typical laser phosphor projectors. BoldColor eliminates the perception that 1DLP^® laser phosphor projector manufacturers must choose between accurate color and high brightness. Through finely tuned color algorithms, BoldColor accurately reproduces color with stunning brilliance and full brightness.

Unlike other products in the market, there’s no need to oversaturate, boost greens, crush whites or blacks, or play with gamma tables. Now that we can achieve even contribution from primary colors, we are able to simultaneously produce accurate color and high brightness.

Top 4 benefits of BoldColor technology

1. Achieves color balance, with even contribution from primary colors
2. Removes the need to use color manipulations like oversaturated greens or crushed whites
3. Accurately reproduces color with stunning brilliance, without sacrificing brightness
4. Produces enhanced color, saturation, and more lifelike visuals compared to typical laser phosphor projectors
