We present a high light efficiency and low power consumption projection engine for mobile device applications. Efficient light coupling and color mixing, high contrast reflective polarization & recycling, and precision molded optics were combined to achieve this high performance LED/LCOS‐based system having a 10.5 mm light engine thickness and demonstrating 8.0 lm/W.
