The Red-Green-Blue (RGB) laser light sourcing has, for a long time, been one of the blocking factors for MEMS-based pico-projector development.
Technical challenges have been overcome by some laser manufacturers [like Osram for one example] that are now providing the three basic colors. It is expected that these lasers will be mass-produced in a single bar─ that is a platform integrating the three laser sources in one instead of three individual lasers, by early 2011.
Single bar RGB laser light source for MEMS pico projectors is expected to be much more cost effective and scalable to mass production. Not only that, there are other benefits of reduced physical size, lower energy consumption and faster modulation rates.
Laser pico projector pricing is then strongly related not only to the cost of RGB laser light source and production volumes but also to initial technology choices, the business model and product strategy.
