| Screen Protector |
A screen protector is used to protect the LCD screens of digital, electronic devices. The personal digital assistant (PDA) is, perhaps, the most commonly used gadget for which screen protectors are used since PDAs are operated via a stylus. If not used carefully, the tip of the stylus can potentially mar or scratch the sensitive LCD screen surface, and so screen protectors were brought to market.
The "first generation" of screen protectors were made from very thin films based on the concept that an extra layer between the two surfaces (screen and stylus) would provide the needed protection to prolong the life of the device. These screen protectors came (and still come) in packs of 10 to 20 protectors and are hand-cut by the end consumer to fit the specific device. Such screen protectors, while offering extra protection, did not completely fill the need in the marketplace. They peeled up easily and they scratched almost as easily as the screens, causing the protector to be replaced often.
The newest generation of screen protectors are made from a much more durable film and are designed to be a more permanent part of the gadget which they protect. The material is a urethane-based film which is a little thicker than traditional screen protectors (.008 inches compared to .005 or .003),[citation needed] but the film is hardly noticeable once installed. The film originated when the U.S. military was looking for a way to protect the leading edges of their military helicopter blades from abrasive airborne particles (sand) while traveling at hundreds of miles per hour. The negative is that it is hard to remove and leaves a sticky residue. It is also made in small sizes, not recommended for bigger than four inch diagonal screens. Since the film is clear, there are problems with UV rays emanating from the display to the eyes and bounce back from the sun. It also does not provide protection from glare and hard to read outdoors.
And for the usage of the cell phone screen, there are mainly 7 kinds of screen protector:
Privacy Screen Protector
