Outdoor LCD

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.
