What’s the Difference Between Laser Phosphor and RGB Laser? by Barco
So you’ve decided to upgrade your fleet with new laser projectors? Great! Now the next step is choosing between the different laser technologies: RGB and laser phosphor. Let’s shed some light on the differences between these two laser solutions. And, perhaps the number one reason why you’re reading this, let’s find out which one fits your needs.
Micromirror Device) chips and directed through the lens on the projection canvas. However, instead of using three different colors, the laser phosphor projectors use just one. The majority go for only blue laser diodes. “Why blue?”, you might ask. Well, the choice for blue lasers is partly cost-driven, but also based on the high density and power efficiency of this color. The blue light from the laser shines onto a spinning yellow phosphor wheel. The chemical compound phosphor absorbs the blue light, and radiates a bright, yellow light. This broadband yellow light is captured and split into the primaries using a color wheel. These can then be used to produce the colored images on the canvas.
Laser phosphor vs. RGB laser: how does it work? The light source in an RGB projector, also called direct laser projectors, contains individual red, green and blue lasers. As we’ve all learned in kindergarten, these primary colors are the building blocks of all other colors. By combining different proportions of these three lasers, the projector can reproduce millions of different shades and hues. The laser output is mixed, What are the main differences? processed by the projector’s DMD (Digital Colors – By design, RGB is a wide color | 36
RGB projectors contain individual red, green and blue lasers. Laser phosphor projectors use just one blue laser. It shines on a yellow, spinning phosphor wheel, which is then projected through a color wheel, creating color images.
