For notebooks, digital cameras and digital cameras, LCD screen it is the lives of these digital products should be properly maintained and maintained so as to prolong their service life. However, the use of the Shijianyichang, some on the LCD screen cleaning problems will follow. On computers, digital cameras, digital cameras, if the LCD screen LCD panels to replace broken the price of the total cost of digital equipment 2 / 3 or more, so here is focused on the LCD screen clean and maintenance programme. LCD Material: LCD screen appears on the surface of a solid black screen, in fact, in this layer on the screen manufacturers will add a special coating. This special coating of the main functions is to prevent users from being used by other sources of glare and reflection, while strengthening its own color LCD screen contrast. But because the manufacturers used by this layer coating materials also vary, of course, the degree of its durability will also vary. Thus users in a clean, must not use any free alkaline solution or chemical solution wipe the screen surface. Wu Ji LCD panels can be divided into two, one is because over time by the stick to stay in the air, dust, is a user inadvertently left the fingerprint and oil pollution. LCD panel itself because of the physical structure of complex design, so in time to wipe the LCD panel, do not use an unknown cleaning solution, not the use of water and alcohol solution. Mistakes here are threefold: Mistakes 1, with a soft cloth or paper towel to wipe LCD screen We can not be with a cloth and paper towels to clean LCD screen, it is easy to scratch "Jiaoqi" LCD screen. For the first category of dust, we can use the LCD panel Lupi lightly polished, can generally choose high-end glasses cloth, but effect is not the best. Fingerprints and oil pollution as the former can not easily remove. Mistakes 2, with water clean LCD screen The use of water, liquid vulnerable infusion liquid crystal displays and equipment within this short circuit will cause equipment to burn expensive electronic equipment. The fingerprints and oil pollution, water still powerless. Mistakes three, with alcohol and other chemical solvent cleaning LCD screen Generally speaking, alcohol is a common organic solvents, can not easily wipe dissolved some of the dirt, if it is only used to clean display case, it's adverse effects. However, we do not use alcohol to clean LCD screens, because the LCD screen, all on the screen coated with a special coating so that the screen has better effect, once the use of alcohol polished display screen, will be dissolved this special layer of Coating, the effect of adverse effects. Chemical solvent is even more undesirable, such chemical agents "Jiaoqi" LCD panel is simply devastating blow, so only choose a safe and effective cleaning agent is the "right path."
