RGB pure laser is capable of achieving High Dynamic Range
One of the most exciting aspects of RGB pure laser projection is the ability to achieve High Dynamic Range (HDR). Because lasers have a tightly focused emission angle, it allows them to achieve higher contrast. Dolby Vision projectors, which use Christie 6P modular RGB laser light sources, are a perfect example of the spectacular visuals that are possible with HDR and RGB pure laser projection.
With blue only laser phosphor projectors, the high contrast benefits of a narrow angle are lost since the laser light gets dispersed and diffused through a phosphor wheel and a yellow notch filter.
