- Optical bonding is a process which attaches the touch panel directly to the LCD, filling a small air gap between the front of the display and the back of the touch panel.
- The reason you would chooses optical bond is because it is easier to read the display through the overlay, especially in sunlight, and is to make the LCD assembly more rugged.
- The different between the two Optical Bonding techniques is that Liquid Optical Bonding uses UV radiation while Dry Optical Bonding uses heat and pressure.
