Optical Bonding


What is optical bonding?


Optical Bonding is a process where a layer of resin(OCR) or film(OCA) is applied between the glass or touchscreen and TFT LCD TFT panel of a monitor, bonding them to make a solid laminate with no gaps or pockets of air. When choosing a screen for any project, you should evaluate the environment and operating conditions the screen will have to endure. Industrial grade screens and panel PCs are made rugged with all types of features available to withstand any type of application. One such feature available to consider is optical bonding.


Optical bonding is popular among the medical, military, transportation and retail sectors whereby a higher performing display is required due to the harsh environments. Optical Bonding is suited to industries that tend to use rugged displays in high reliability environments or industries where displays need to be seen in high ambient light conditions. The process of Optical Bonding is particularly well suited and much more effective when applied to devices that operate outdoors or in heavily lighted environments.
