Film is to protect the screen, you can wipe the dirt without affecting the screen, and if wipe directly without film, small scratches will be left on the screen,
It is better to stick film. In addition to anti-scratch, there are two benefits: The first is to protect the LCD, and the second is the visual effect; wherein protect the LCD is the priority among priorities. First clean the computer screen to be pasted, which must be clean, otherwise there will be small bubbles caused by the dust. First, take out the screen film to make sure whether its size fits the screen, then you can see the stickers marked 1 and 2 on the protective?film, folding the stickers marked 2 as shown below. Second, turn over the screen film, put the sticker marked 1 downward, which should be sticked to the screen surface. it is enough to uncover a point. Three, began to paste a shown below, try to make one side of the film parallel with computer screen shell along one side, slowly put down. Because film has electrostatic adsorption ability, it will automatically be adsorbed onto the screen. Two cases may appear during the sticking process. First, there are some little dust absorbed on the film, so there will be bubbles after sticking. Solution: using the prepared adhesive tap, finding the little dust and sticking off the dust with the tape. Second, appearing small bubbles, tear the film back a little, release the bubble and paste back. If it still doesn't work, you can use magic cloth. It can be done by slowly wiping through. Four, continue to stick with patience, dealing with small bubbles while sticking until the completion of the paste. Pay attention to finish at a corner when coming to an end, and then tearing the tag marked 2. There is likely to remain a few small bubbles after the completion of the paste, which will disappear after about a week in general conditions.
Generally the screen doesn't need to stick film, if it is anti-dazzle screen, do not stick film, because the screen will not anti-dazzle after sticking film. 15-inch film cost less than 2 yuan, whose characteristics of anti-static, anti-scratch and good heat dissipation are bluffing, tell you the price is 20 yuan,50 yuan or 80 yuan, actually the film they stick for you is the cheapest. Heat dissipation performance of dell machine is not good, 15tr has high configuration but the screen technology is the same with14r and15r , , if you want to use in relatively clean environment, and keep better maintenance for your computer, do not stick film.
