LCD Enhancements & LCD Glass Direct Bond

The Direct Bond removes two internal reflective surfaces by eliminating the air gaps between the LCD surface and the rear side of the outer glass or plastic substrate. AR (Anti-Reflective) or AG (Anti-Glare) coatings on the front surface increase the contrast ratio even further. A 20% improvement in contrast ratio is typical with this treatment.
Ruggedization / Environmental

  • * Moisture due to condensation is eliminated between the LCD and the outer substrate
  • Impact testing has shown significant improvement with a direct bonded front surface vs. an “adhered” – frame/gasket configuration with no bonding interlayer
