EIZO Optical Bonding Guide

Optical bonding is a method that's used to provide increased visibility and durability to LCD monitors. A layer of resin is used to fill the gap which appears between the LCD module and the cover glass of a monitor, adhering the two together.

By doing so, the transmission of light is increased, improving the visibility of the display. If the gap of air is left, there can be a loss in the light's intensity due to the light bending as it passed through the gap and panel which both have different refractive indexes which affects the screen's readability.

The increased light transmission that occurs thanks to optical bonding also means that glare is also significantly reduced. Without bonding, light from an external source passes through the panel and the gap, refraction causes some of it to be reflected back, creating glare on the screen.



The additional resin layer in optical bonding also provides increased physical durability to the screen and makes it more resistant to scratches and dust.

For touch monitors, the optical bonding maintains consistently accurate touch response making it easy to use and reliable. A monitor with optical bonding also helps prevent condensation from occurring for improved readability in environments with wide temperature ranges.
