In situ tribometry with real-time imaging for assessing durability and wear mechanisms of easy-to-clean coatings on glass for touchscreen substrates

•An in situ tribomery system with real-time imaging capability was developed;•An easy-to-clean (ETC) coating for touchscreens and/or display substrates was characterized using this technique;•The durability and wear mechanisms of ETC coatings on glass were investigated;•The in situ real-time observations clearly correlate with the ex situ analyses;
