However, as with anything of great value, we must concern ourselves with maintenance and upkeep. The PSP screen has a delicate beauty that can be marred by any number of unfortunate accidents. Furthermore, the size of the screen and the glossy black background only draw attention to the eventual fingerprints, dents, scratches, and other imperfections that find their way onto the screen.
Sony does not offer a screen protector accessory, but third-party accessory manufacturers have created a plethora of screen protectors to meet the demand of fearful PSP owners interested in protecting their displays. Screen filters, or protectors, are thin pieces of transparent plastic that act as a second skin to protect the PSP screen from scratches, fingerprints, and any other types of markings. However, not all screen protectors are created equal. These covers come in different forms and sizes, as well as thicknesses and materials, but they all aim to protect the PSP screen with varying degrees of success.
The filters themselves can introduce a variety of problems, ranging from difficult installations to degraded image quality, which could make them more trouble than they're worth. You have to be careful to avoid trapping any air bubbles while applying the filter to the PSP. Several filters we've seen come with a squeegeelike, plastic card, which can be used to flatten out the filter and squeeze out air bubbles as you apply the protector. Also, remember to clean your PSP before applying the screen protector, as removing existing blemishes and random particles ahead of time will greatly reduce the number of trapped air bubbles.
It is also important to realize that application of a screen protector is not a one-time occurrence, as they are designed to be replaced after a period of time as marks and scratches accrue. You'll likely go through a number of screen protectors over the lifetime of your PSP.
