iPhone 15 Screen Guard (HD/ Matt/ Privacy )

•   HD tempered glass
•  Clarity: HD tempered glass offers high-definition clarity, making it a popular choice for screens and display devices.
•  Thickness: The thickness of tempered glass usually ranges from 0.3mm to 0.5mm. A good balance between thickness and sensitivity is crucial for touch screen performance.
• Hardness: Quality tempered glass should have a hardness rating of 9H, which means it is highly resistant to scratches from objects like keys or knave
• Edge Finish: The edges should be smooth and slightly rounded (2.5D or 3D curved edges), reducing the risk of chipping and making the glass more comfortable to handle.
• Touch Sensitivity: It should not interfere with the touchscreen’s responsiveness. High-quality tempered glass preserves the touch sensitivity and accuracy of the device.

Matt Glass 

• Clarity: While matte glass reduces glare, it can sometimes slightly reduce screen clarity compared to HD glass. High-quality matte tempered glass minimizes this loss of clarity, maintaining good screen visibility.
• Fingerprint Resistance: Matte glass tends to show fewer fingerprints and smudges due to its textured surface. A quality matte protector will have a coating that enhances this resistance.
• Smooth Touch: The surface of the matte glass should feel smooth to the touch, not overly rough. It should provide a comfortable and precise touch experience.
• Adhesive Quality: High-quality matte tempered glass should have strong adhesive to ensure a secure, bubble-free installation and prevent it from lifting over time.

Privacy tempered glass

• Privacy Protection: The main feature of privacy tempered glass is its ability to limit the viewing angle, typically to 60-90 degrees. Only the person directly in front of the screen should be able to see the display clearly, while those viewing from the side see a dark or obscured screen.
• Clarity and Brightness: While privacy tempered glass can reduce screen brightness and clarity slightly, high-quality protectors minimize this effect, maintaining as much clarity and brightness as possible.
• Hardness and Durability: The tempered glass should have a hardness rating of 9H to ensure it is resistant to scratches from everyday objects like keys and coins.
