Cover glass is a protective glass layer placed over the display surface to safeguard the delicate internal components. The cover glass shields the panel from scratches, impacts, dirt, and environmental factors. It can be made from standard glass, hardened/tempered glass, or specialized materials (like Gorilla Glass).
In industrial and medical devices, cover glass is often thicker (e.g. 2 mm) or equipped with functional coatings (anti-reflective, anti-bacterial, anti-UV, etc.). It may also serve decorative or input purposes, containing printed logos or embedded touch buttons. The choice of cover glass critically affects the display’s optical performance, appearance, and how it integrates with touch technology.
