Endurance Bond

Endurance Bond™ – Rugged Optical Bonding

Optically bonded displays offer optical characteristics and mechanical robustness superior to any other solution.

Optically Bonded “Cover Glass” can be any number of materials such as glass, polycarbonate, acrylic, touch screens, or other optically clear overlay material placed in front of the LCD. Integrated ITO Heaters and EMI/RFI shielding can be included in the bonding process if needed, providing a product that is compliant to the most extreme of requirements.

Benefits of Optical Bonding include:

Improved Optics and Glare Reduction – Optical Bonding reduces or eliminates reflection from internal and external light sources. When combined with an Anti-Reflection front surface it is possible to dramatically reduce glare and increase light transmission from the assembly yielding a most satisfying and accurate viewing experience.

Protection of the display – Displays typically have a polarizer that is a soft plastic material as the front surface. This front surface is easily scratched, even from routine cleaning. With optical bonding a protective “cover glass” is placed on the display. The optically bonded display can be further built into a system which is weatherproof, in fact we have had products which were bonded for use by divers under water.

Safety – An optically bonded display can help contain materials in the event of breakage (an impact directly to the display or crash in a vehicle). This is well suited for transportation application and is also used in zero gravity spacecraft. A display that is easily read is also a benefit where the driver/operator needs to look away momentarily to read a display before focusing back on driving or the task at hand.

Reduced Power – In a high ambient brightness environment an optically bonded display will allow you to turn down the installed backlighting system. In fact in a sunlit environment going from 12% to 1.5% reflection will have the same effect on contrast ratio as going from 500 nits to 3500 nits. This results not only in a savings in power consumption, but also less heat is generated which must be removed from the assembly.

Ergonomics – A display with reduced glare and a sharp clear image reduces eyestrain and is essential for those whom make there living from behind an LCD. The American Optometric Association lists glare as contributor to Computer Vision Syndrome (CVS) and reducing glare is effective in reducing the effects of CVS. http://www.aoa.org/x5253.xml

Dust and Moisture – By eliminating the gap between the LCD and the cover glass this area can no longer be a place where dust and moisture collect.

Vibration and Mechanical Shock – It has been demonstrated that an optically bonded display is superior at resisting the effects of vibration and mechanical shock.
