PVA Solidifies Optical Bonding Expertise with New Patent

Halfmoon, NY – PVA, a global supplier of automated dispensing and coating equipment, is pleased to announce that it has been awarded a new patent for optical bonding. The patent is an addition to PVA’s original bonding patent, “Machine for Optical Bonding, System and Method of Use Thereof.”

The new patent is an expansion on the methods developed for optical bonding which are utilized for the manufacturing of LCD touch screens in a variety of industries including automotive and military. This patent addition solidifies PVA’s optical bonding technology and expertise, and furthers development in optical bonding technology.

Optical bonding of a transparent substrate, such as a sheet of glass, to another transparent Substrate, or to a video screen, such as an electronic display, may improve the ruggedness and enhance the optical clarity in ambient light. Bonding transparent Substrates to each other presents many difficulties, including maintaining the structural integrity of the bonded Substrates and manipulating the fill material used to bond the substrates. Specifically, air pockets may form in the fill material between the two substrates during the placement and bonding process.

The presence of air pockets between the bonded substrates results in cracks at locations where air pockets are present. Accordingly, a need exists for an optical bonding machine, system and method that address these issues.

PVA’s focus on optical bonding software and hardware tools demonstrate the company’s commitment to developing technology to reduce setup times and take the guesswork out of process and application development for the growing display bonding market.

PVA is a world-class innovator of high quality, repeatable dispensing and conformal coating systems. The company manufactures turnkey solutions that help customers improve their competitiveness, such as coating inspection, optical bonding and curing ovens.
