OPTICAL BONDING

 Optical bonding is the process of laminating cover glass or touchscreens to the LCD cell. It is a process that applies a layer of transparent material such as OCA (Optically Clear Adhesive) or OCR (Optically Clear Resin) between the layers to completely fill the air gap.

What is "Optical Bonding”?

Optical bonding is the process of laminating cover glass or touchscreens to the LCD cell. It is a process that applies a layer of transparent

material such as OCA (Optically Clear Adhesive) or OCR (Optically Clear Resin) between the layers to completely fill the air gap.

The adhesive is completely transparent, the structure and colour of the adhesive will not transform through the use of time. Any display in

an outdoor environment or high ambient light conditions can be improved with our matured technology and experience. EDT provides

optical bonding solutions to a wide variety of applications like handheld device for outdoor use, navigation systems, industrial, medical

displays, and ATM equipment, for clear visibility under sunlight or in bright environment.

Optical bonding advantages

Optical bonding has some the following advantages,

(1) Enhanced sunlight readability (5–10 times, depending on application).

(2) Increased impact resistance (3–8 times, depending on the bonded cover glass).

(3) High shock and vibration tolerance.

(4) Very low reflectance for touch screens in desired applications.

(5) Greatly enhanced life by protecting the display materials from the humidity.

(6) High-quality optical bonding of performance-enhancing auxiliary components, such as AR, AG, AR/AG/hard coat/anti-smudge

     and heater glasses, touch screens, and UV, EMI, and sunlight filters.
