How to maintain LCD

With the increasingly mature liquid crystal technology, prices gradually become more common, liquid crystal display began to stride into the common consumption field. Nowadays, many desktop monitors have been updated, and the inventory of LCD monitors in the market is rapidly increasing. Therefore, more and more consumers are concerned about how to maintain and maintain LCD monitors. In this regard, the reporter specifically interviewed LG Electronics, a professional manufacturer of LCD display, ask their engineers to give you some good suggestions worth learning.

Expert Suggestion 1: maintain a dry working environment and avoid contact with chemicals

It must be known that water is the natural enemy of Liquid Crystal. If the humidity is too high, the liquid crystal display will be exposed, leakage and short circuit will occur after condensation, and the liquid crystal display will become blurred. Therefore, do not place the liquid crystal display in a humid place, or let anything with moisture enter the liquid crystal display. If you find that only the screen surface is misty before starting the boot, use a soft cloth to gently wipe it. If moisture has already entered the LCD display, you can turn off the display and bring the LCD back to the sun, or use the lamp to bake and evaporate the water in it. However, do not expose the LCD screen to the sun, which will lead to aging of components. Experts remind consumers that major international manufacturers such as LG pay great attention to after-sales services. If there is a serious tidal event, it is best for normal users to contact the local brand after-sales service provider, ask them for help and comparison insurance. Because the serious moisture will damage the LCD components, the user will contain high humidity LCD power, will lead to liquid crystal electrode corrosion, resulting in permanent damage.

In addition, the daily use of hair gel and frequent use of mosquito killer agents in summer will also cause damage to Liquid Crystal Molecules and even the entire display, leading to the shortening of the overall display life, therefore, we should try to avoid contact between the display and chemicals.

Expert suggestion 2: Avoid overload LCD display for a long time

First, do not make the LCD High Brightness for a long time. The LCD display mode is different from the CRT mode. Long-highlighted screen can easily shorten the use life of the backlight tube of the LCD display. Therefore, when you do not need it for a long time, you should disable the display. In addition, the brightness of the LCD can be adjusted to a lower value during daily use. These measures will be of great help to extend the life of the LCD.

Second, try to avoid displaying the same screen for a long time. The LCD will cause internal aging or burn-out due to long working hours, especially when the same screen is displayed for a long time. The reason is that the LCD can easily cause some pixels to overheat after a long period of operation. Once the limit is exceeded, permanent damage will occur and cannot be repaired. This forms a common "bad point ". Because the pixels of the LCD display are composed of Liquid Crystal bodies, when working at full load for more than 96 hours, it will be accelerated to aging, severe hours or even burned out. Therefore, experts remind consumers that if they have to work for a long time, it is best to take a break intermittently or change the screen display content at different time intervals. If they just leave temporarily, the Screen Saver should be started, or the brightness of the display can be reduced to a full white screen, which not only delays the aging of the LCD screen, but also avoids hardware damage.

Expert Suggestion 3: Reduce Unnecessary touch or vibration

The LCD screen is very fragile and delicate, so you should get rid of the bad habit of pointing fingers to the screen. This is because even a slight click may generate a local bad point, which may even lead to a black point, which may easily lead to more bad points, this is why some users may discover more and more bad points over a period of time. Note that the power consumption of the LCD is relatively small, but the voltage of the transformer after the LCD is very high. Pay special attention to safety. Do not open the back cover of the LCD when the LCD is powered. Even after a power failure, the voltage remains quite high. The CFL Transformer in the background lighting component still carries a high voltage of about V, so it is best not to touch it at will.

In addition, the impact resistance of liquid crystal display is also relatively poor. Even the latest products, the impact resistance is far inferior to that of CRT display. This is because LCD displays contain many precision glass elements and sensitive and delicate electrical components. Once a strong impact occurs, the LCD screen, related components or circuit may be damaged. When you move a liquid crystal display, you often do not pay attention to moving the screen, which may damage the surface of the liquid crystal display. Therefore, experts strongly recommend that you avoid great impact and apply pressure on the surface of the LCD screen.

Expert suggestion 4: Correct cleaning of liquid crystal display surface dirt

If dirt is found on the surface of the liquid crystal display, clear it in the correct way. It is best to use soft and non-fiber materials, such as skim cotton, lens paper, or glasses cloth. Generally, water can be removed. However, if the cleaning effect cannot be effectively achieved, you can purchase commercial LCD cleaning products. One expert pointed out that consumers should not clean up with cleaning liquid containing ammonia, alcohol and inorganic salts.
At present, the liquid crystal display manufacturing technology is very focused on low-definition radiation, anti-reflection, anti-glare, anti-static interference, environmental protection and other designs, so the process of each part has undergone multiple protection measures, such as multi-layer film mirror processing, or coating more special polymers, etc. These special chemicals are often damaged by chemicals that contain ammonia, alcohol and inorganic salts, resulting in the display slowly losing the true optical transmittance, it may cause color distortion caused by reduction reflection, or reduce the effect of anti-interference and anti-static. This will not only affect the eyes, but also affect the image display quality, and the original protection functions will also be damaged, the color and security are compromised, so consumers have to be cautious.

Expert suggestion 5: you cannot disassemble the LCD display if any problem occurs.

Because the LCD is too precise and delicate, you cannot change components as you would with a common CRT. Therefore, no matter what problems it has, do not disassemble the LCD display on its own, this is not the scope of DIY "game"; once the LCD display is suspected to work abnormally, be sure to seek help from professional vendors. Experts once again reminded consumers that the CFL shunt in LCD backlight lighting components may still carry a high pressure of V (although it is a micro-current) after being shut down for a certain period of time, even if there is no harm to the human body, for LCD display, non-professional personnel may cause new component faults if they are not properly handled. In severe cases, the screen may be permanently unavailable.

The above are some important maintenance methods proposed by engineers of lg LCD. It can be seen that LCD is indeed a very delicate 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 the purchase. In particular, LG has recently made a commitment to keep liquid crystal display intact, that is, there are neither bright spots nor hidden spots, philips also launched the same LCD product. Because they are not only technically competent, but also have a large number of after-sales outlets distributed throughout the country, and their services are more professional and high-quality, users can buy more assured and more comfortable to use.
