Traditionally, various vacuum‐based processes have been used for producing interference‐type anti‐reflection (AR) coatings on large area substrates for different commercial applications. In this paper, the development of sol‐gel derived AR coating on large plastic substrates for display application is presented. The sol‐gel dip coating process was used to deposit thin films on large size plastic panels. By developing solutions with different refractive indices, multi‐layer thin‐film AR coating stacks were designed and fabricated. Optical constants of the coating materials were characterized by using spectroscopic ellipsometry. Optical, mechanical and environmental tests were performed on the sol‐gel derived AR coating stack. These coatings possess good uniformity and meet stringent automotive specifications. This technology has been commercialized successfully for dashboard instrument panel application in Toyota Prius, a new hybrid car. The sol‐gel derived AR coating possesses equivalent or superior properties when compared to the major commercially available AR coating products. These AR coated panels are also useful for other commercial applications.
