Screen Protector vs. Tempered Glass — What's the Difference?

Difference Between Screen Protector and Tempered Glass


Key Differences

A screen protector is typically a thin, plastic film or a polyurethane material that adheres to the screen of a device to guard against scratches and minor abrasions. Tempered glass, on the other hand, is a type of safety glass processed by controlled thermal treatments to increase its strength, providing superior protection against impacts and deep scratches.
The installation process of a screen protector usually involves carefully aligning the film and smoothing out any air bubbles. In contrast, tempered glass protectors are more rigid and are applied using a silicone adhesive, which makes them easier to align and less prone to air bubbles.
Screen protectors offer a virtually invisible layer of protection and usually don't affect the touch sensitivity or clarity of the display. Tempered glass protectors are thicker, offering more noticeable protection, and can sometimes slightly affect the feel and responsiveness of the screen.
In terms of durability, a screen protector may need to be replaced more frequently due to wear or peeling. Tempered glass, being more robust, generally lasts longer but may shatter upon strong impact, necessitating replacement.
Price-wise, basic screen protectors are generally cheaper than tempered glass options. However, the latter offers better value in terms of the level of protection and longevity it provides for the device's screen.
