As mobile devices become more advanced, the display screens are getting larger and larger. It is inevitable that scratches will damage these transparent plastic screens. Most handset manufacturers do not offer replacements for displays and those that do, are expensive. These scratches can give your new expensive Smartphone a shabby appearance. Displex has the solution for this common problem. To use Displex just apply the polishing paste to the damaged display screen and apply heavy pressure for a couple of minutes with a soft, clean cotton cloth. For deeper scratches feel free to repeat application. Please note: Apply only to transparent sections of the display NOT coated surfaces! Displex actually dissolves the plastic lens and is polished with fine particles. The corners of the scratch are rounded off and the bottom is filled with the dissolved material. This item is non-returnable and non refundable. Displex is not for use with touch screens. For use on cell phones, PDA, iPods, mP3 players, PsP LCD displays.
