With the popularization of protective membranes, smart product decorations such as screen protection film and protective film have also developed rapidly, especially the protective film is more important. However, in the actual purchase of the protective film, in the face of a variety of protective film products on the market, many users do not know how to buy the appropriate ET protective film. So what are the main points of attention to the protection film? What are the characteristics that cannot be ignored?
1. Through the degree: This point is difficult to identify with the naked eye, it is best to use optical instruments; there is also a clumsy method to cut a small piece of protective membranes to be selected and put it on the middle of the computer desktop. A blank Word file, check the degree of blank Word gear in the area or different film areas or different film areas (professional point is called brightness). In contrast, you can choose the brightest material to pass through the best protective film.
2. Mist: Misty is mainly to look at the display of the display. After the protective film that is to be selected is opened in turn, the more the screen color of the screen is smaller. Of course, the better this material. The better it is. If this method is used with a black test board, it is easier to see the difference. Another method is to turn on a sunlight in a slightly darker room. After tore the protective film, take the up and down formation membrane between the eyes and the lights. Uniformly distributed in the membrane, that is, affecting the scourge that affects the mist. The more severe the fog -shaped things, the greater the foggy degree, the worse the material, the better it means that the fog will affect the permeability rate, but it will be the same as Through the rate is two different concepts!
3. Static electricity: Because the liquid crystal display is a sensitive device is afraid of static electricity, the smaller the electrostatic electrical electricity when the protective film is pasted. The ash is on the desktop, or a small piece of paper dandruff on the desktop, and then tear the top layer of the protective film of the protective film (for 3 layers of materials), and then tear the protective film with a silicone layer, tear off off drift off, tear off off dripping off off, tear off off drift off, tear off off drift off, tear off off drift off, tear off off drift off When this layer of protective film, the use layer (silicone surface) is used to go close to the ash or paper scraps to see if the protective film will absorb these things to the silicone layer of the protective film. The stronger it means that the higher the electrostatic material generated by this material, the worse the material, and the better, the better. The entire market I know that only the all -in materials of the Japanese Fuji high -quality printing will not be adsorbed at all.
4. Scratch: This point is the most concerned about everyone, and it is also a problem that all manufacturers have been solved. At present, the scratch materials in the industry are basically similar (2-3h), and the characteristics are good. Only scratching and non -scratching are divided into 3H pencils (sold in the stationery store) with the hardness of the Japanese San Ling brand at 45 degrees at 45 degrees. Hardness requirements. The simple method is to use a slightly hard metal device or a newly cut nail on the use of the material with the strength of the handwriting pen. If it is very easy to scratch, it is determined that it is not scratched. Essence The cutting processing manufacturers should pay more attention to the uniformity of the entire batch of materials, because some material manufacturers are not in place in terms of coating uniformity.
5. Whether to prevent fingerprints: Because the screen size has become larger and larger in recent years, and more and more smart machines plus capacitor screen (touch with your fingers, it is different from the old -style resistance screen to use the pen to draw it), The protective film needs to have the function of anti -fingerprints. Now these products are expected by more and more customers.
