How to maintain LCD in wet weather

Expert advice 1: Keep dry working environment and avoid contact with chemicals. Tentacles know that moisture is the natural enemy of liquid crystal. If the humidity is too high, dew will form inside the LCD, which will cause leakage and short circuit after condensation, and the LCD will become blurred. So don't put the LCD in a damp place, and don't let anything with moisture enter the LCD. If it is found that there is only fog on the screen surface before starting, gently wipe it with a soft cloth; If moisture has entered the LCD, you can turn off the display, turn the LCD back to the sun, or bake with a desk lamp to evaporate the moisture inside. But be careful not to point the LCD screen at the sun, which will cause aging of components. Experts remind consumers that international manufacturers such as LG attach great importance to after-sales service. If there is a serious water incident, it is safer for ordinary users to get in touch with local brand after-sales service providers and seek their help. Because severe humidity will damage the components of the LCD, when the user turns on the LCD with high humidity, it will lead to the corrosion of the LCD electrode and cause permanent damage. In addition, the hair gel that everyone uses every day and the mosquito killer that is frequently used in summer will also cause damage to liquid crystal molecules and even the whole display, shortening the life of the whole display. Therefore, contact between the monitor and chemicals should be avoided as much as possible. Expert suggestion 2: Try to avoid overloading LCD monitors for a long time. First of all, don't leave the LCD in a high brightness state for a long time. The display mode of LCD is different from CRT. If the screen is highlighted for a long time, it is easy to shorten the service life of LCD backlight lamp. Therefore, attention should be paid to turning off the monitor when it is not used for a long time. In addition, in daily use, the brightness of LCD can be appropriately reduced. These measures will greatly help to extend the life of LCD. Secondly, try to avoid displaying the same picture for a long time. Liquid crystal display will cause internal aging or burn out due to long-term work, especially when displaying the same picture for a long time. Because LCD works for a long time, it is easy to overheat some pixels. Once it exceeds the limit, it will cause permanent damage and cannot be repaired. This forms the so-called "bad point". Because the pixels of LCD display are composed of liquid crystal, it will accelerate aging and even burn out if it works continuously at full load for more than 96 hours. Therefore, experts remind consumers that if users have to work for a long time, it is best to let them rest intermittently or often change the contents displayed on the screen at different time intervals; If you just leave temporarily, start the screen saver, or turn down the brightness of the display screen, or turn it into a full white screen. This can not only delay the aging of LCD screen, but also avoid hardware damage. Expert suggestion 3: It is very fragile and delicate to reduce unnecessary touch or vibration of LCD screen. You should get rid of the bad habit of pointing your finger at the screen. Because even a slight click may produce local bad spots, even black spots, which is easy to cause the increase of bad spots, which is also an important reason why some users will find more and more bad spots after using it for a period of time. It should also be noted that the power consumption of LCD is relatively small, but the transformer voltage behind LCD is still very high. Pay special attention to safety, and don't open the back cover of the monitor when charging. Even after power failure, the instantaneous voltage is quite high, and the CFL transformer in the background lighting assembly still has a high voltage of about1000 V. It is best not to touch it at will. Not only that, the impact resistance of LCD is also very poor, even the latest products are far less than CRT monitors. This is because the LCD contains many precise glass components and sensitive and precise electrical components. Once it is strongly impacted, it will damage the LCD screen, related components or circuits. When you move the LCD, you often grab the screen carelessly and move it, which may also damage the surface of the LCD. Therefore, experts strongly suggest that we should avoid the oscillation of large impact force and put pressure on the surface of LCD screen. Expert suggestion 4: Remove the dirt on the LCD surface correctly. If dirt is found on the LCD surface, you should use the correct method to remove it. It is best to use soft, non-fibrous materials, such as absorbent cotton, lens paper or glasses cloth, which can generally be cleaned with water; However, if the cleaning effect cannot be effectively achieved, you can consider buying special cleaning products for LCD currently on the market. One expert pointed out in particular that consumers should not choose cleaning solutions containing ammonia, alcohol and inorganic salts. At present, the manufacturing technology of LCD attaches great importance to the design of low radiation, anti-reflection, anti-glare, anti-static interference and environmental protection, so the manufacturing process of each component has undergone multiple protective treatments, such as mirror treatment of multilayer films or coating with more special polymer compounds. These special chemicals are usually destroyed by some chemicals containing ammonia, alcohol and inorganic salts, which causes the display to slowly lose its real optical transmittance, or produce color distortion caused by refraction and reflection, or reduce its anti-interference and anti-static functions. This is not only bad for eyes and affects the display quality of images, but also the original protection function is destroyed, and the color and safety will be greatly reduced, so consumers have to be cautious. Expert's suggestion 5: Do not disassemble the LCD when encountering problems. Because the LCD is too precise and delicate, it is not allowed to change parts at will like ordinary CRT monitors. Therefore, no matter what kind of problems it has, don't disassemble the LCD by yourself, which is not the "game" scope of DIY; Once you suspect that the LCD monitor is not working properly, you must find a professional manufacturer to help solve it. Experts remind consumers once again that CFL alternating current in LCD backlight lighting module may still have a high voltage of 1000V (even a slight current) after it is turned off for a certain period of time. Even if it is harmless to human body, for LCD, if it is not handled well by non-professionals, it may lead to new failures of the module, and in severe cases, the screen may never work. The above are some important maintenance methods proposed by engineers of LG LCD. It can be seen that liquid crystal is indeed a very exquisite high-end product, and its quality and performance require high manufacturing technology and technology. Therefore, it is best for ordinary users to choose some well-known brands at the beginning of purchase, especially in recent years, LG has made a promise that LCD displays have no bad spots, that is, there are no bright spots and no dark spots, and Philips has also launched the same LCD products.
