HMI Backlighting & Light Guide Technologies

When designing a Human-Machine Interface (HMI), it is important to carefully evaluate the application and requirements of an HMI before determining the type of backlighting that should be used.

Inside our HMI Backlighting and Light Guide Technologies Ebook we will review the pros and cons of what type of backlighting best suites your application.

• Capacitive Touch Membrane Switches
• Tactile Membrane Switches
• Silicone Rubber Keypads
  • Using Tactile Switches or Conductive Carbon Pills

As technology evolves, customers across all industries are seeking thinner and more advanced lighting solutions in their designs to produce sleek user interface products. Engineering and marketing teams have shifted towards HMI designs with backlighting requirements that common existing technologies can fulfill at a low cost.

With advances in backlighting technology in recent years, light guide film technology has become more efficient and affordable than ever. Both backlighting and light guide film technology have low tooling and unit costs which renders fiber optic and EL backlighting nearly obsolete in the HMI industry.
