LD to replace LED in automotive HUD systems

Posted: 07 Jul 2014     Print Version  Bookmark and Share

Keywords:laser diode  LED  HUD 

Nichia Corporation is set to commercialise blue and green semiconductor laser diode models specifically designed for automotive head-up display (HUD) systems.

Semiconductor LDs are excellent light sources that offer high luminance and excellent colour reproducibility.

By replacing LEDs, which are currently the most common light sources for automotive HUD systems, with semiconductor LDs, the following benefits can be expected:

  • Larger head-up display field of view,
  • Lower energy consumption,
  • Higher contrast,
  • Extended range of reproducible colours
  • Nichia has achieved improved reliability and quality for the new LD models. Aφ5.6mm can package (i.e. metal package) was chosen for its high performance for semiconductor LD packages, and the LD die has an improved conversion efficiency from electric power to light.

    Nichia plans to start shipping test samples from October 2014 and mass production from October 2015.
