LuphiTouch® Backlighting Solutions for Membrane Switches

Illuminate Your Interface with Optimal Backlighting Technology

Proper backlighting is essential for membrane switch functionality, ensuring clear visibility in all lighting conditions while maintaining the sleek, durable qualities that make membrane switches valuable. At LuphiTouch®, we engineer high-performance backlighting solutions tailored to your specific operational requirements.

Backlighting Technology Comparison

LED Backlighting

• Best for: Status indicators and localized illumination

• Key Features:

  • High-intensity point lighting

  • Energy efficient operation

  • 50,000+ hour lifespan

• Considerations:

  • Requires diffusers for even panel illumination

  • Ideal for button backlighting rather than full panels

Electroluminescent (EL) Backlighting

• Best for: Ultra-thin full-panel lighting

• Key Features:

  • Uniform glow across entire surface

  • Minimal thickness (under 0.5mm)

• Considerations:

  • Limited to single-color output

  • Requires high-voltage driver (90-120V AC)

  • Typical lifespan of 3,000-5,000 hours

Fiber Optic Backlighting

• Best for: Premium applications demanding perfect uniformity

• Key Features:

  • Exceptionally even light distribution

  • Cool operation with no hotspots

• Considerations:

  • Highest cost option

  • More complex installation process

  • Limited brightness compared to LEDs

Light Guide Film (LGF) Backlighting - Our Recommended Solution

• Superior Advantages:

  • Perfect balance of cost and performance

  • Excellent uniformity across all switch areas

  • Multiple color options available

  • Energy efficient low-power operation

  • 50,000+ hour lifespan

• Customization Options:

  • Adjustable brightness levels

  • Zoned lighting configurations

  • Custom color matching

  • Environmental sealing
