Laser Phosphor

Laser phosphor projection

Laser phosphor projectors are the ideal choice for corporate spaces, educational institutions, retail, entertainment venues and government facilities where long life, minimal maintenance and a low cost of operation are paramount.

​​​​​​​​​What is laser phosphor?

Laser phosphor is a lampless projection illumination platform that uses blue laser diodes as the primary light source. To generate the three primary colors – red, blue, green – the blue light from the laser diodes shines onto a spinning wheel that is coated in a phosphor compound. The blue light excites the phosphor, emitting yellow light. The yellow light is then segmented using dichroic coatings to create red and green light while the blue light component directly passes through a diffusion segment in the phosphor wheel. In some cases, designs can include one wavelength of low-cost blue laser diodes to excite the phosphor wheel and a different wavelength of blue laser diodes to inject directly into the optical path. The projector then sends the separated red, green and blue colors onto an imaging surface, such as a DLP® chip, which then sends the light through a lens and onto the projection screen. Eliminating the need fo​r lamp and sometimes filter replacements, laser phosphor projection means reduced consumables, low maintenance and reduced downtime. Learn more »

Typical laser phosphor illumination

 

Christie BoldColor Technology

In a survey Christie® conducted with rAVe Publications, members of the commercial AV industry were asked what the most important factor is when choosing solid state illumination projectors like laser phosphor and RGB laser, to which 78% of the respondents indicated “color fidelity.” Christie BoldColor Technology creates the color balance needed to accurately reproduce colorful visuals without sacrificing brightness. It achieves this by employing blue and red laser diodes as well as a patented optical chamber and specialized saturation software to produce enhanced color and saturation compared to typical laser phosphor projectors.

With Christie BoldColor, the perception that manufacturers of 1DLP laser phosphor projectors have to choose between accurate color and high brightness is eliminated. Christie BoldColor accurately reproduces colors 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 the primary colors, we are able to produce accurate colors and high brightness simultaneously.

As a developer of premium projectors, it is important for Christie to take a leadership position in accurately replicating color as it was intended while delivering full brightness capabilities. Other manufacturers choose to distort and modify the video information to achieve higher brightness and target more pleasing visuals (albeit inaccurate reproduction) by crushing whites and blacks and oversaturating colors. At Christie, we believe it isn’t our place to modify the content. We believe that we should display content precisely as it was created so it appears exactly as intended. We’ve achieved the most natural, accurate colors at very high brightness levels through our proprietary BoldColor Technology. Learn more »
