Abstract

Anti-glare coatings with irregular surface microstructures formed during a spray process have a gloss value between 50 to 100 gloss units, a pencil hardness ≥8H, and no sparkling issues on touch screen displays. Optical profiler image (with ×50.3 magnification) of the anti-glare coating surface (70 gloss units) shows irregular microstructure patterns which are random locally but uniform in large area. The light scattering on the anti-glare coating surface is caused by these irregular surface microstructures. Thus the specular reflection is significantly reduced, causing glare reduction, gloss decrease, and haze increase. * Songwei Lu slu@ppg.com Coatings Innovation Center, PPG Industries, Inc., 4325 Rosanna Drive, Allison Park, PA 15101, USA 1234567890();,: 1234567890();,: Journal of Sol-Gel Science and Technology Highlights Sol–gel based transparent functional coatings including easy-to-clean coatings, anti-glare coatings, single layer anti- reflective coatings, and anti-fingerprint coatings have been developed and commercialized for display applications by PPG Industries, Inc. ● ● ● ● ● Keywords Easy-to-clean Anti-glare Anti-reflective Anti-fingerprint Spray application Touch screen displays 1 Introduction Figure 1 shows a glass sample of half-coated EC coating.
