Sony picoprojector teardown shows ST, Microvision inside
The picoprojector measures 6-inch by 3-inch and is 0.5-inch thick (145mm by 77mm by 13mm), weighs 210 grams and provides a 1920 by 720 pixel full color display, Chipworks reports. The 32 lumen brightness level is good for producing a 40-inch display in a darkened room, Chipworks asserts.

The project subsystem is labeled Microvision Inc. with the MEMS die on the underside marked ST. Chipworks reports the MEMS die itself as measuring 4.5mm by 7.3mm with the dual-axis mirror measuring 1.1mm by 1.2mm.
Next: The MEMS
Chipworks describes the MEMS as a "sophisticated" design although its use for laser beam steering is just one way to produce a projection display. Chipworks name the other methods include liquid crystal on silicon (LCoS), digital light processing (DLP) and holographic laser projection (HLP).
