  • Cost-effective Solution to Eliminate Ghost Images in Head-up Displays
    • Download Technology Summary  

      Head-up display (HUD) systems in automobiles are in increasingly high demand because they can project a substantial amount of critical information onto the windshield, enabling drivers to obtain information more quickly and naturally and thus significantly enhancing driving safety.

      However, HUD systems produce two overlapped reflected images, thus generating a ghost image. This causes difficulty in identifying the image. The most prevalent current solution to address this problem is a wedge-shaped windshield configuration. However, this method requires high manufacturing costs due to the need for a specialized wedge windshield.

      360ip’s Partner has developed an optical film that can be applied on normal windshield for eliminating ghost images. The benefits of the Partner’s technology as compared to alternative solutions include:

      • Better image quality
      • Easy fabrication
      • Compatible for all kinds of light sources
  • Light Guide

      Head-up display (HUD) systems in vehicles are in increasingly high demand because they can project a substantial amount of critical information onto the windshield, enabling drivers to obtain information more quickly and naturally, and thus significantly enhancing driving safety and efficiency.

      Convention systems use halogen or arc lamps as light sources. These have major disadvantages such as high power consumption, short lifetimes and high temperatures. Light-emitting diode (LED) light sources have been introduced as an alternative. These devices have lower power consumption, longer life and lower thermal energy. One major challenge with such multiple-LED systems is ensuring the uniformity of the light sources. Optical systems comprised of multiple lenses have been developed to tackle this problem. However, these systems are typically complicated in design and comparably expensive because each lens requires great precision in fabrication.

      360ip’s Partner has developed an illumination and image projection device with multiple light sources that achieves uniformity through a tapered light guide which projects the light onto a liquid-crystal display (LCD). Since the system uses multiple light-emitting modules, various low power-consuming light sources can be used. The benefits of the Partner’s technology as compared to alternative solutions include:

      • Long lifetime
      • Low fabrication cost
      • Uniform illumination
      • High efficiency
      • Use of low power luminescence
      • Flexibility to use a variety of light sources
