What is optical bonding

Optical bonding is a process of filling in the traditional air gap with optical bonding material resulting in better viewability and additional protection. One of the benefits from using our optical bonding process is the elimination of internal reflection, improved contrast and higher brightness. Through our automated equipment processing we can meet customets quantity demands while ensuring quality requirements.

At EXSON, we offer different options ranging from OCR to OCA along with different thickness's for display sizes from 2" to 98".
