Comparison between optical bonding (left) and without bonding (right)
Optical bonding is used to laminate touch screens or cover glass to display. Special glue and a unique manufacturer’s technology are required for the entire operation. Optical bonding technology also allows connecting a display with transparent layers of electromagnetic protection or with special coatings, e.g. AG (anti–glare), AR (anti–reflective), HC (hard coating) and polarizing filters.
Reduced reflections up to 65% and refractions
The adhesive used in optical bonding reduces the refraction effect, as the refractive index of the adhesive is similar to glass
Increase the brightness up to 10%
By bonding the LCD module and glass together it removes the interruptions and chances for the light to be reflected back. More light gets through to the surface of the screen and therefore the image is brighter.
Prevents from Humidity, Condensation and Dust
The most obvious benefit to adding a resin bonding layer between the glass and LCD module is that it physically prevents dust and liquid ingress from getting between the two.
Optical bonding should therefore be considered for any outdoor application as well as indoor applications e.g. production halls and warehouses, in hospitals.
