Application Example Optical Bonding

Optical Bonding Adhesive for Better Image Quality

Optical bonding is the joining of two layers of material with a liquid optical clear adhesive. This optical bonding adhesive is applied with a dispenser. This method allows a significantly improved display performance compared to other methods. The optical bonding manufacturing process eliminates air gaps between the glass and the bonding display. This process and our exceptional optical bonding equipment lead to an increased durability and an excellent image quality.
