What is Optical Bonding?
The process of applying an optical clear liquid to a digital display, such as LCD or plasma, to bond a cover glass and/or touch sensor to eliminate the air gap between each layer. This provides improved image clarity, especially in outdoor or bright light environments.
When to Use Optical Bonding
The optical bonding process is ideal for producing screens that are highly durable and will stand up to harsh environments. Screens that are assembled using an optical bonding process will also have increase touched reliability. This is a result of higher pressure accuracy through the substrate.
Benefits of Optical Bonding
- Better bonding
- Decreased refraction
- Improved touch responsiveness
- Increased durability
- Eliminates air pockets
- Reduced glare
