Screen protectors are a thin film of sticky plastic that you can use to protect the glass (or plastic) screen of your gadgets. Most current mobile phones and tablets have large touch-screen interfaces. Such a large screen is very prone to getting scratched, scuffed or otherwise marked. Having this extra layer of protection means that your gadget remains in excellent condition, and the plastic film gets scratched instead.
What’s special about screen protectors for touch-screens?
The screen protectors are made from plastic, which is an electrical insulator. Touch screens usually work by a capacitive matrix, which basically means it detects the conductivity of a human finger, rather than being pressure sensitive. For this reason, screen protectors for touch screens need to be conductive, to allow the screen to detect your finger.
Therefore screen protectors for touch-screens are likely to contain various compounds to ensure that the screen can detect your finger, such as metallic and graphite-based mixtures. If you just used a sticky-back plastic film, then touch-sensitive device would not respond to touch anymore.
What gadgets can I protect?
Essentially, any gadget with a screen. This usually includes mobile phones, ebook readers, games consoles, tablets and laptops. Some of the typical gadgets you can protect with a screen protector include:
- Amazon Kindle eBook Reader
- Apple iPad and Apple iPad 2
- Apple iPhone (all versions)
- HTC Desire
- Sony Ericsson Play
- Sony PSP
- Nintendo DSi and Nintendo DS
- Apple iPod Touch
