20120070603 | SCREEN PROTECTIVE STICKER - A screen protective sticker structure comprises a plurality of screen protectors overlaying each other. Each screen protector has an optical film and an adhesion layer disposed on the optical film. Each adhesion layer has certain stickiness, and the stickiness of the adhesion layers is increasing or equal from the top layer to the bottom layer. The adhesion layer of the outer layer is overlayingly disposed on the top surface of the optical film of the inner protector. Thus, the instant disclosure can be used easily and improved protective ability for a display screen. | 03-22-2012 |
20130309433 | SCREEN PROTECTIVE FILM STRUCTURE - The instant disclosure relates to a screen protective film structure for disposing on an outer surface of an electronic device. The electronic device has a display portion and a frame portion. The screen protective film structure has a light-permitting film and an adhesive portion. The light-permitting film is disposed on one side of the display portion. A central space is formed between the light-permitting film and the display portion. The adhesive portion is connected to the light-permitting film and having a plurality of adhesive protrusions. The adhesive protrusions are abutted to the frame portion, and a gap is formed between the adhesive protrusions. The gap is in communication with the central space and the ambient. Thus, trapped air between the screen protective film structure and the electronic device can be relieved. | 11-21-2013 |
