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.
