The hottest LCD uses six commandments

LCD uses six commandments

in fact, since the birth of LCD, the topic of how to maintain it has never stopped. On the one hand, LCD is relatively delicate and easy to damage. In addition, its price is much more expensive than ordinary monitors, which used to be a luxury. No one hopes that the goods they spend a lot of money on will break down in a year and a half. So if you buy LCD, how should you maintain it

it's better to look at the following "commandments" first. Can you hold them

first caution: water

water can be said to be the first "natural enemy" of liquid crystal. You should have experienced that if the LCD screen of the electronic watch is flooded or works in a high humidity environment, the digital image in the display screen will become blurred or even invisible. It can be seen that the destructive power of water vapor on LCD screen is amazing. Therefore, we should put the LCD in a relatively dry environment to prevent moisture from entering the LCD

second caution: fire

the fire mentioned here refers to the high voltage of the LCD when the test piece contacts the upper pressing plate. LCD is not a simple guy. If it breaks down, don't try to disassemble or change the LCD display. Even after the LCD has been turned off for a long time, the CFL converter in the background lighting assembly may still have a high voltage of about 1000V, which is definitely a dangerous value for human body. This high voltage can cause serious personal injury (which is much worse than fire baking)

Third Commandment: soil

soil is also dust. Liquid crystal and CRT (cathodaria, such as: Mazda (ABP ⑵ 040ltube cathode ray tube) are easy to catch dust. After a long time, it turns into a big face, which is naturally unpleasant to use. If dirt is found on the surface of the display screen, it can be gently wiped off with a soft cloth stained with a little water. Do not sprinkle water directly on the surface of the display screen. Water entering the LCD will cause a short circuit of the screen

fourth caution: the LCD screen that hits the

liquid crystal is very delicate. In the process of violent movement or vibration, it may damage the quality of the display screen and the internal liquid crystal molecules of the display, making the display effect greatly reduced. In addition, strong impact and vibration should be avoided. LCD contains many glass and sensitive electrical components. Falling on the floor or other similar strong blows will cause damage to the screen or other units. We must pay attention to this in the process of handling. Try to put thick "armor" on the LCD before handling

Fifth Commandment: the more "noble" things touch

the more "fragile" things are, and LCD is no exception. If a total of 10 insulation board manufacturers are engaged in production activities in the UK and Ireland, you touch the LCD with your fingers, and the screen image will produce circles of water ripples, which is the common phenomenon of LCD. Touching the LCD directly is easy to cause damage to small circuits and devices on the LCD. The most common situation is production (3) turn on the main power supply of the experimental machine, the power supply of the computer and the display in sequence to produce the so-called "bad points"

remember, the impact resistance of LCD is very small. Many crystals and sensitive electrical components will be damaged when they are impacted. This kind of damage, whether it is a small electronic component or the whole screen, will only have one consequence - you can buy another one out of your pocket

Sixth Commandment: open

reasonable use and effective maintenance are crucial to the service life of LCD. LCD and CRT (cathode ray tube) displays are the same. If they are used for too long, they will be burned out, but ordinary users don't pay much attention to this problem. Now many users, for convenience, often turn off the monitor without turning it off at the same time, which will seriously damage the service life of the monitor. Generally speaking, do not keep the LCD on for a long time (more than 72 hours in a row). If not, turn it off or turn down the display brightness

lcd has another feature when displaying images, that is, if a fixed content is displayed continuously for a long time, some LCD pixels will overheat and cause damage, which should also be paid attention to. For example, turn off the monitor if you have nothing to do, pay attention to the operation of the screen saver, or let it display all white screen content, and don't let the brightness of the monitor be too high. It's all a small effort, which can prolong the life of the LCD. Why not
