“Moth’s Eye” Approach Will Reduce Screen Reflections and Glares

Sony’s water and dust-resistant Xperia Z smartphone and tablet are two examples off marvelous technology that consumers will have access to this year. While smartphones are hot commodities that rack up sales for retailers, smartphones also serve as personal assistants (PDAs), calendar planners and reminders, alarm setters, and so on. While all these features allow consumers the opportunity to use their smartphone in the small events of life, consumers also want to know that their products are protected and safe from the earth elements. What does it benefit consumers if they cannot take pictures out on the beach without fear of losing (or killing) their smartphones? How can you have genuine pictures of life underwater if there is no waterproof technology available so that you can snap photos underwater? These technologies may be considered to be a waste of money and time by some, but their greatest importance comes with the outdoors and even the indoors.

The Moth’s Eye Approach is a strategy employed by Asahi Glass Co., a Japanese company known for glass production. The strategy is called the Moth’s Eye because moths are not troubled by sun glares and reflections. The reason? Moths have an eye covering that improves their night sight and day sight. Can you imagine looking at your smartphone or tablet without the sun blocking your phone or tablet screen? If Asahi has its way, consumers will no longer struggle to keep their phone outside in sunny weather or in darkness. The “Moth’s Eye” approach, in honor of moth sight, will use a nano coating to cover the displays of smartphone screens so as to block out more sunlight than phone displays do currently. Asahi Glass Company will work on the anti-reflective and anti-glare coating along with Rolling Mask Lithograpy, a nano coating company founded in 2008 by Dr. Boris Kobrin, Dr. Mark Brongersma, and Julian Zegelman. Rolith not only develops nano coatings based upon the Moth Eye, but also the Lotus Leaf, Strider on Water, and other natural phenomena.

The Moth’s Eye nano coating was discovered by C.G Bernhard (1967), when he discovered that the moth cornea emits a smaller amount of light than the human cornea. Sharp, Apple’s glass display maker, announced the use of Moth Eye technology back in October 2012 as a nano coating to apply to its liquid crystal display (LCD) screens. Sharp will not only use the Moth Eye technology for its smartphones and tablets, but also its 3D television sets.

While Moth Eye technology has been developed for electronics, it is also being considered as a source to improve the formation of current plastics and safer X-rays. Sony filed a patent (US Patent 7,633,045) to use Moth Eye to produce a unique set of optical devices that will come out under the company name at some indefinite point of time in the future. Moth Eye technology will be far more advanced than Apple’s Retina display, which develops screens based on the highest threshold of human sight that can distinguish between the pixels on a screen. While Steve Jobs touted Retina display technology as the maximum threshold of human sight, a recent rumor has it that Samsung Electronics will use diamond-shaped pixels in its soon-to-be Galaxy S4 instead of the usual Pentile-Matrix pixel display (while also producing a pixel density of 440ppi, or pixels per inch).
