New Anti-Reflective Coating

DuPont has developed a new anti-reflective coating for display applications that is cured using UV light. The coating is highly durable and has exceptional adhesion to substrates. Able to withstand heavy abrasion, even with steel wool, the coating offers reflectivity that ranges from 1.2% down to 0.5%.
The anti-reflective property of the coating is achieved in an interesting fashion. Because of its refractive index and thickness, light reflected by the underlying substrate is out of phase with light reflected from the front surface. The two phases cancel each other out, dramatically reducing reflectance and improving image clarity, especially in daylight or outdoor conditions.
DuPont has developed the anti-reflective coating to the point of commercialization, but has not yet commercialized it. Samples are available, along with extensive laboratory test data, but this technology can be licensed for displays applications only.
