75.4L: Late‐News Paper: The Path to 100 lm/W in Embedded Projection: a New DLP‐Based Imaging Architecture using MEMS Spatial Light Modulator‐Based Diffractive Illumination and UV Laser‐Pumped Phosphor or Quantum Dot Down‐Conversion

Low efficiency (< 20 lm/W) and brightness are critical problems to solve before embedded projection in consumer electronics devices can become mainstream. Here we present a novel DLP-based projection architecture offering efficiencies approaching 100 lm/W using a MEMS-based diffractive spatial light modulator backlight and UV laser-pumped phosphor/quantum dot down-conversion.
