Overview

This reference design provides an electronics subsystem designed to drive an automotive augmented reality (AR) head-up display (HUD). DLP® technology enables bright, crisp, highly saturated head-up displays that project critical driving information onto the windshield of the car, reducing driver distraction and increasing situational awareness. This design uses the DLP3030-Q1 chipset, which includes the DLP3030-Q1 0.3" DMD, the DLPC120-Q1 Automotive DMD controller, and the Piccolo™ TMS320F28023 microcontroller operating as an LED driver and illumination controller.

Features
  • When paired with an optical system, this reference design can output up to 90 lumens with 7.1W input power
  • Greater than 80 pixel per degree HUD resolution at 10° FOV
  • 3.3A LED drive output
  • Over 5000:1 dimming ratio
  • Reduced System Cost
