Provider of PicoP display technology platform, Microvision has successfully combined direct green laser samples, obtained from major manufacturers, into the benchtop pico projector prototypes. The integration represents a crucial step towards commercializing PicoP display engines by utilizing direct green lasers. The display engine is anticipated to provide substantial commercial benefits in performance, power, size, and price.
The existing pico projection engine of Microvision utilizes a synthetic green laser, and blue and red laser diodes to generate a complete color image. The green lasers are IR lasers, which are manipulated to decrease the wavelength to deliver a green light. The conversion procedure generates a complex system with many units held to rigid tolerances, hence making the manufacturing more difficult.
The direct green lasers have the potential to create green light natively, helping in simplifying the laser manufacturing and design processes. With lower cost, lower power, and smaller size, direct green lasers are an ideal alternative for synthetic green lasers.
Microvision’s VP of R&D and Applications, Sid Madhavan stated that the direct green laser diodes would have the potential to meet the performance needs for integrating into the PicoP display platform.
