Privacy Glass is a thin coating that has been hardened to 9H during manufacturing and curing. This makes it scratch-resistant, even when in contact with sharp objects like keys or a knife. The glass is coated with an oleophobic and hydrophobic layer that prevents fingerprints and other contaminants from affecting the screen. It is crystal clear and perfectly reflects the displayed colors. It also does not interfere with touch sensitivity and is exceptionally smooth, making it a pleasure to glide your finger across the screen. Its additional function is privacy protection - the glass blocks the light emitted from the display at a certain angle, creating an effect similar to that of ATM screens. The glass primarily serves to protect the screen from scratches and minimizes the risk of screen damage in the event of an unexpected drop.
