Optical Bond

AGDisplays’ optical bonding service is our best performance of all our bonding services. Optical bonding is ideal for industries such as military, avionics, and medical, because of the durability our bonding service provides. We use nothing less than the industry-standard in bonding material and in-house processes.

An LCD is made of a stack up of various types of materials that create and enhance certain optical properties of the LCD. Often, LCD build designs that add additional hardware to the LCD, such as touchscreens or front cover glass, are constructed in such a fashion that air gaps are left between the layers of its components. Internal reflections are created by the air gap created between these layers. Optical quality can be greatly affected; internal reflections decrease optical clarity, along with the leaving the LCD vulnerable to contamination and moisture collection (condensation). Optical bonding is the process of adjoining the LCD and touchscreen or cover glass together to create a single optical index. Put simply, the air gap between the LCD and the cover glass is eliminated, therefore benefiting the LCD’s optical functionality and reducing the number of reflection points.

In performing a bonding procedure on your LCD, your display is guaranteed to be more rugged and less prone to environmental vulnerabilities such as dust collection and moisture condensation. Our bonding is performed with a proprietary adhesive, which is solidified with a quick but reliable curing method.

LCDs are optically improved not only for direct sunlight environments, but in any type of ambient light conditions.

AGDisplays offers full touch screen and full cover glass optical bonding.
