What is Optical Bonding?
Optical Bonding use liquid gel to laminate/affix the cover glass or touchscreen on the front of the LCD panel. The air gap between the cover glass and the panel is completely filled with silicon-based gel/ adhesive. The assembly is cured in a process that affixes the panel together while solidifying the adhesive
The two main reasons for optically bonding a TFT panel to a cover plate are to improve optical performance and durability. By selecting appropriate adhesive that closely matches the index of refraction of the panel and the cover plate, it will thus reduce the number of internal reflecting surfaces that can lead to degradation of optical performance. Providing a durable adhesion between the flat panel and the cover plate improves the displays’ ability to resist shock, vibration and moisture.
Benefits–Better Viewability in bright ambient conditions
LCD Panels have plastic surfaces that are not vandal or weatherproof. To protect your display investment, most display installations require a glass to protect the LCD. Optical bonding can help solve the problem of reflection caused by glass while providing adequate bond strength to help on safety concerns on broken glass.
Benefit–Increase Anti-Shock/ Vibration Capabilities
Optical bonding increases resistance to mechanical shock and vibration!
Optical bonding is an effective means of improving resistance to shock and vibration. This is especially useful for military and transportation applications.
Filling the gap between the protective glass and panel keeps out dust and moisture. Condensation or dust can make a display unreadable.
