General Digital offers optical bonding and optical film laminating services to enhance the optical performance of an LCD, OLED or Plasma display.

Optically bonding an LCD, OLED or Plasma display improves both optical performance and durability. Optical Bonding is the affixing of two optical elements to one another using a liquid adhesive. Typically, one of the optical elements has an antireflective, ITO (Indium Tin Oxide), or other coating. Typical bonded overlays include contrast enhancement filters, EMI/RFI filters, vandal shields, touch screens, and thermal heaters.

Practical Use

• Augmentation of Optical Performance of Flat Panel Display and Overlay
• Increased Luminance
• Increased Contrast
• Reduced Internal Reflections

• Improved Ruggedization
• Bonded display assemblies are able to withstand the high shock and vibration typically associated with MIL-STD-901 and MIL-STD-810 applications
• Vandal Prevention

• Extended Operating Temperature Range Through the Use of Bonded LCD, OLED or Plasma Display Heaters

• Elimination of Condensation and Moisture Between LCD, OLED or Plasma Display and Overlay

Types of Filter Coatings/Etchings

• Antireflective (AR)
• Single-Sided (recommended for bonded filters)
• Double-Sided (recommended for non-bonded filters)

• Antiglare (AG)
• Chemically Etched
• Mechanically Etched

• Easy-Clean (smudge resistant)
