The ESD Privacy 28° Premium Glass is a high-end tempered glass screen protector designed to provide both privacy and electrostatic discharge protection. With a 28° narrow-viewing-angle privacy filter, it ensures that screen content is clearly visible when looking straight on but becomes dark or obscured when viewed from the sides, helping protect sensitive or private information. The “ESD” (Electrostatic Discharge) feature means the glass has a special conductive or dissipative coating or layer that helps drain static electricity — this reduces dust attraction and protects delicate electronics from electrostatic shocks. Made from 9H-hardness glass, it offers strong resistance to scratches, wear, and everyday impacts. The glass is generally about 0.3–0.33 mm thick, balancing durability with good touch sensitivity. An oleophobic (oil-repelling) coating further helps keep the surface clean from fingerprints and smudges. Installation is often designed to be smooth and bubble-free (with air-release or strong adhesive), and the full-glue bonding ensures the glass adheres well to the screen for better clarity and durability.
28° Privacy Filter: Limits viewing angle so side-viewers can’t easily see your screen
ESD / Anti-Static Coating: Helps dissipate static electricity and reduce dust
Hardness: 9H — strong scratch resistance
Thickness: Typically ~0.3–0.33 mm — plenty of protection without sacrificing touch sensitivity
Durable Material: Tempered glass designed for impact resistance
Oleophobic Layer: Resists fingerprints, oil, and smudges
Good Installation: Usually uses full-glue or strong adhesive for bubble-free application
Strong Adhesion: Full glue helps keep the glass firmly attached to screen
Balanced Clarity: Despite the privacy filter, offers good visual clarity when viewed from front
