Thanks to the special privacy filter integrated into the protective glass, the display light is only allowed through from certain angles. This provides effective protection against side glances from, for example, neighboring passengers on trains, planes, or buses. Note: Due to the privacy filter, the fingerprint function cannot be supported. Compared to so-called 2D protective glasses, the Displex Full Cover tempered glasses (3D/Curved) cover not only the active display area but the entire display area. The Displex tempered glass has a hardness rating of 10H, making it not only more scratch, break, and shock-resistant than comparable brand products but also surpassing high-quality sapphire glass (9H) used in luxury watches. The Displex protective glass is manufactured to within 0.05 mm of the smartphone contours, ensuring a perfect fit for your smartphone. Additionally, the protective film is ultra-thin, allowing all common protective cases and covers to be used with the tempered glass. The high-tech shatter protection integrated into the Real Glass by Displex guarantees absolute safety, even in the event of breakage of the tempered glass. After the protective glass is installed, the high-performance silicone ensures optimal adhesion properties and a clear appearance. With the Easy-On Eco mounting frame and the accompanying video tutorial, the installation of the tempered glass is quick, easy, and precise. Good for the environment: The Eco mounting frame is made from 100% recyclable premium cardboard and can be safely recycled with paper waste after use.
