Overview

This reference design details the design of a control board for the DLP5531-Q1 DMD. The DLP5531-Q1 DMD is a spatial light modulator with over 1.3 million pixels that can steer light to create digitally controlled illumination distributions. The design shows a simplified power architecture with a reduced component count to save space and reduce cost. When combined with optics, an input video sources, and a computer or other means of control, this design can be use to demonstrate Adaptive Driving Beams, Glare-Free Beam Steering, Reflective Traffic Sign Dimming, Pedestrian Dimming, Symbol Projection, and OEM Branding.

Features
  • OpenLDI video input
  • Brownout detection with safe DMD parking
  • Spread spectrum to support automotive EMI requirements
  • LED enable signals to synchronize LED illumination with the DMD

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
