Optical bonding is no longer a new technology for enhancing displays. There are many vendors who offer bonding, so what are the differences? Why choose Luminary Optics over the others? Consider the issues associated with bonding. Consider the years required to get good at bonding. In theory, bonding is simple; you merely glue a piece of glass to a display. You may be asking yourself - "what's so difficult about that?" Bonding takes years to master and years of discovery as to what to do and not to do in the process. Bonding is easy if you expect and pay for broken and contaminated displays. Try doing it correctly for over 10 years and keep failed displays below 1%. Suddenly, bonding becomes much more challenging.
Luminary uses silicone based materials in a proprietary formulation utilized in a direct “Over-the Bezel” style of bonding. Why? It's superior. The formulation is not merely silicone. Our years of study and formulation development has created a tried and true material that has been subjected to the most stringent tests. Our proprietary material has the highest adhesion and cohesion of most bonding materials and is superior to any “off-the-shelf” silicone formulation. It can pass full Mil testing, including the “high altitude, rapid decompression” test.
Using the "over-the-bezel" gasket and fill method for bonding keeps the cover glass and display attached to each other throughout shock, vibration and most important, torsion stress. In torsion stress, displays and cover glass naturally try to bend in separate directions. This causes delamination. Our method will not delaminate in most severe torsion conditions.
Bonding subjects the display to ESD and other handling issues. Experience has shown that relative newcomers to bonding consider display failures of 2% or higher to be reasonable and common. This “fallout” is unacceptable at Luminary. Our years of bonding experience have taught us to have less than .5% failure. Our failure rate is so low that we offer 100% coverage for the display if it should fail under our care.
Many bonding companies have merely licensed themselves with bonding material companies. These material companies are more interested in selling material than training and supporting their new licensees. Moreover, these materials have properties that are known to have production issues with displays and applications.
Optical Bonding offers the lowest overall reflection over any other method. By eliminating or reducing reflective loss, a display can maintain a high contrast ratio even in bright ambient conditions.
