SID Vehicle Display Conference October 2004: 2.6 1 Low Cost Anti-Reflection Technology For Automobile Displays Bruce D. MacLeod, and Douglas S. Hobbs Abstract— Light reflecting from instrument panel and center II. BACKGROUND console automobile displays is distracting to drivers and necessitates overhanging dashboard designs that take up The concept of using surface structures in lieu of multilayer valuable interior space. A recent trend toward displaying thin film coatings to control reflections from optical surfaces increasing amounts of information with navigation and has been discussed since the 1970s. The principle is derived communication systems, has compounded the significance of from the work of Bernhard et al, who discovered that the eye light reflection. The conventional anti-reflection (AR) of the night moth reflects very little light, due to the graded technique of coating the display cover with thin-films to index nature of the moth’s cornea [1], as shown in Figures 1 reduce reflections, has generally not been employed due to and 2. It was hypothesized that the low reflectivity surface of cost, lifetime, and performance issues such as poor viewing the moth’s eye imparted a degree of stealth that protected the angle, durability, and adhesion loss. Diffuse textured surfaces moth from its predators, primarily the owl. Wilson and are sometimes used at
