A screen protector is a sheet that is applied onto a screen to prevent damage to it. After all, scratching the screen not only ruins the viewing experience, but also the response of the device in the damaged part of the screen. With the advent of touch-screen technology, it became easier to scratch the screens, ruining both the viewing and the sensory response of the device. The earliest screen protectors were just thin films applied onto screens to serve as the surface subject to dust, fingerprints and other dirt or damage.
When we say that more advanced technologies are needed, it does not mean that the entire product needs to be redesigned. In essence, the screen protector is a clear thin film that is stuck onto the screen with an adhesive, serving as the outermost layer and taking most of the damage instead of the screen itself. The first screen protectors were quite thin so as to remain transparent, and not affect the picture quality, focus or coloration. When personal digital assistants (PDAs) entered the market, they were essentially the first consumer-oriented touch-screen devices. This required stronger and harder protection due to touch-screen activities, while still retaining the responsiveness of the device.
The newest screen protection material is made of very thin tempered glass. This was the easiest way to have a protective layer that is both transparent and easy to manipulate. They were also very easy to stick onto screens. Tempered glass screen protectors are fairly new, and there may still be potential improvements to the technology. In recent years, tempered glass screen protectors have emerged on the market. Tempered glass can still break, as it is a solid piece that can be shattered with sufficient force. Fortunately (and this can be verified with car windshields), tempered glass does not shatter, but stays in one piece that can be easily removed.

More innovations have been introduced in other areas relating to screen protectors. An example of this is pre-cut sizes for popular devices, so that you don’t need to do any tedious measurement and cutting to have an exact fit to your screen. It used to be very difficult to stick the screen protector on the device. Air bubbles could be trapped under the plastic layer, creating a gap that looks unappealing and affects the operation of the touch-screen. These are eliminated with rigid screen protectors which can easily be pressed down as one piece onto the device. Click here for more info about iPhone 5 screen protector.
If you are going to buy a screen protector, consider the three most important aspects: material, thinness and adhesive. A thin screen allows for good response and transparency. A strong protector will keep your screen free from any damage, and can be useful if you buy and sell devices often. Lastly, the adhesive strength will make it difficult to remove the protector, and will keep it attached throughout its useful life. The adhesive strength will keep it properly attached for a long time.
