What is optical bonding?
While optical bonding is just one of the display enhancement
elements offered by E3 Displays, it is perhaps the most critical.
The optical bonding of displays for ruggedization purposes
serves as the foundation for all enhancements. Without a quality
bond using an application specific adhesive, at some point the
display will be rendered unreadable through delamination,
yellowing, clarity degradation or excessive “glow marks”.
Optical bonding is the process of attaching a glass/plastic/filter
substrate or touch panel to an LCD module. Optically clear
adhesive (OCA) is placed between the cover substrate and LCD
to completely fill the air gap. The assembly is cured via a
UV-light process which fixes the display/substrate together
while solidifying the gel, creating an optically brilliant and
ruggedized display solution.
