How Does Optical Bonding Work?

September 8, 2021

The optical bonding process is crucial when it comes to the manufacturing of LCD’s and touch screen systems.. Without optical bonding, screens would have lower brightness and contrast resulting in diminished readability and be less durable. , 

What is Optical Bonding?

Optical bonding consists of adhering the touch sensor or cover glass to an LCD panel.  This process secures the two parts together to create a solid bond between them without any pockets of air or air gap between the layers. 

Some benefits that optical bonding provides include:

  • Reduced parallax issues
  • Improved touch accuracy
  • Increased durability
  • Dust and moisture protection
  • Brighter visuals
  • Higher contrast and readability

The Optical Bonding Process at Apollo 

Here at Fortec US, we’re experts when it comes to optical bonding. Our process, VacuBond®, leads the industry and is the most advanced form of optical bonding. We use a dry process utilizing a pure silicone gel sheet with the bonds performed in a vacuum chamber which yields perfect results every time. The VacuBond® process can be used for display sizes up to 32 inches with all touchscreens and cover glasses. As well, it is particularly beneficial in smaller displays with no bezels that are often difficult to bond.
