How to maintain liquid crystal display

If you have a laptop or a desktop LCD on hand, you must be pampering, right? But for that faint liquid crystal display, have you taken good care of it? Do you often touch the lovely blue screen with your hands? In fact, we often do not pay attention to the use of LCD monitor maintenance. Although the service life of LCD is up to more than 10 years, it is very important to keep careful maintenance at ordinary times.

To understand how to maintain a flat panel monitor, you need to know a little bit about how it is displayed. Liquid crystal display (liquid Crystal display, known as LCD) as the name suggests, is the use of "liquid crystal" (liquid Crystal) as the material of the display, "Liquid crystal" is a material between the solid and liquid, the heating will appear transparent state (transparent liquid), and cooling will crystallize (chaotic solid-state), is a regular molecular arrangement of organic compounds; from the chemical point of view, liquid crystal is an organic compound, composed of long rod-shaped molecules, in a natural state, these rod molecules of the long axis is roughly parallel. Now on the market of liquid crystal display, mostly refers to thin film crystal display TFT (Thin Film transistor), its display principle is to use the physical characteristics of liquid crystal: In the LCD panel contains two pieces of sodium-free glass material, called substrates, sandwiched between a layer of liquid crystal, When the beam is passing through this layer of liquid crystals, the liquid crystal itself will be controlled by the voltage is irregular state, so that the beam is blocked or passed smoothly. Liquid crystal display principle as shown in the diagram, liquid crystal display is through the characteristics of the liquid crystal (molecular arrangement or voltage reasons to pass or obstruct the principle of light), to achieve the goal of saving electricity and health.

According to the principle of liquid crystal display and practical operation experience, I suggest that we should pay attention to the following points in the use process:

　Maintain a dry working environment

According to the working principle of liquid crystal display, it is very harsh to the air humidity, so it is necessary to ensure l it can work in a relatively dry environment. In particular, it is not possible to bring moisture into the interior of the display, so this is especially critical for some of the more humid users in the environment, such as the humid areas of the southern air. I think Chongqing's users should have more experience. If so, the author suggests that it is best to prepare some desiccant (pharmacies are sold), to keep the micro-environment around the monitor drying, or to prepare a clean soft cloth, at any time to keep the screen dry. If the water has entered the liquid crystal display, it is necessary to place the display in the dry place, so that the water slowly evaporate, do not open the power supply, otherwise the display of the LCD electrode will be eroded, which makes a blunder.

　　Pay attention to your operating habits

Bad working habits can also damage the health of the LCD monitor. For example, some people like to work while drinking tea, coffee or milk. As we all know, this often endangers the "health" of the keyboard, which in the same way endangers the delicate display. If you accidentally pour tea and other on the monitor, you will not use your own mouth to fight. In addition, some people in the use, open notebook computer does not pay attention to, often led to the scratches on the LCD screen, damage to the display of protective film and so on all back to affect its life. Therefore, good work habits not only on your physical and mental health, but also on the healthy display, are closely related.

　　Avoidance of the abuse of volatile chemicals

Through the introduction of the internal material and display principle of the liquid crystal display, we should recognize the fragility of the liquid crystal display to some chemicals. No matter what the monitor, the liquid is to avoid the three homes, not to mention the chemical agent. Here, I would like to emphasize the need to pay attention to other volatile chemicals on the LCD display. For example, we often use hairspray, summer frequently used mosquito repellent, etc. on the liquid crystal molecules and even the entire display will cause damage, resulting in the entire display life of the shortened.

Fixed-time quantitative cleaning screen because of dust and other unclean substances, LCD display on the display often appear some unsightly stain scar, so to regularly clean the display. If you find stains on the display screen, the correct way is to take a little glass detergent with a soft cloth carefully wipe off stains, wipe the intensity to light, otherwise the monitor screen will be short circuit damage. Cleaning the display also to the regular quantitative, frequent scrubbing is also wrong, that will also cause some adverse effects on the display.
