A Japanese company by the name of Oji has developed the fabrication technology of patterned sapphire substrates (PSS) for LEDs which improves the performance of front luminance of LEDs by more than double compared to that of LEDs with non-structured sapphire substrate, by applying the technique of precise coating with fine particles. The technology will come to market in 2016. Some of the applications for this material include LED backlighting, a means of providing large displays with a way of increasing the number of colors it can display, car lighting, military applications and much more. Whether this technology will ever be used by Apple in future products is unknown at this time. However, the benefits of it just might catch Apple's R&D team's interest enough to get them to do a little more investigating into how this could apply to future sapphire applications that they may have in mind.
