About 60,000 hours, even if you open 8 hours a day, a LCD TV can be used for more than 20 years. However, the color cast problem may be caused by the aging of the backlight source of the LCD TV. Similar to a light bulb, this light source cannot generally be used for 20 years, and when the basic life span reaches an ordinary time, the phenomenon that the light intensity weakens will appear. But this can be replaced. Then it is reasonable maintenance.
Relative maintenance and maintenance of LCD TVs is relatively simple, and it is advisable to prevent too much production from accumulating. Lightning and thunderstorms should be protected from lightning and moisture, indoor humidity should not be too high, and machines should not be covered with cloths, at least in the boot state. Because the LCD screen will produce more heat when it is working. It is not possible to contact the LCD screen with a corrosive liquid.
LCD TV adopts the principle of backlight and uses a lamp tube as a backlight source. The auxiliary optical module and the liquid crystal layer control the light to achieve an ideal display effect. Liquid crystal is a regularly arranged organic compound, which is a substance interposed between a solid and a liquid. At present, a nematic liquid crystal liquid crystal having a molecular arrangement most suitable for manufacturing a liquid crystal display is generally used. The liquid crystal itself cannot be configured to emit light. It mainly displays images by changing the arrangement of liquid crystal molecules due to an electric field generated by a change in voltage.
LCD screen material:
The liquid crystal panel is mainly composed of two pieces of sodium-free glass sandwiched by a sandwich composed of a polarizer, a liquid crystal layer and a color filter. The surface of the LCD screen looks like a solid black screen. In fact, manufacturers will add a special layer of coating on this screen. The main function of this special coating is to prevent the user from being reflected and glare by other light sources while using it, and at the same time enhancing the color contrast effect of the LCD screen itself.
However, because the coating materials used by various manufacturers are not the same, of course, its durability will be different. Therefore, the user must not wipe the surface of the screen with any alkaline or chemical solution when cleaning.
1) The method of correctly removing the dirt on the surface of the LCD TV The LCD screen is the core part of the LCD TV, and it is naturally the focus of cleaning. The LCD display surface is covered with glass. If you find dirt on the surface of the LCD monitor, use the correct method to remove the dirt.
There are two types of stains on the LCD panel. One is the dust in the sticky air that accumulates over time, and the other is fingerprints and oils that the user inadvertently left behind. To remove dirt from the LCD screen, the media used is preferably a soft, non-fibrous material such as absorbent cotton, lens paper, or a soft cloth, which is then gently wiped with a small amount of glass cleaner (wipe when lightly applied) , otherwise the screen will be short-circuited due to damage), prohibit the use of chemical solutions such as alcohol, do not use a hard towel to scrub the surface of the screen, so as not to wipe the screen surface and affect the display, can not use rough cloth or paper items Because this type of material is prone to scratches.
Do not spray cleaner directly onto the surface of the screen. It can easily flow into the screen and cause a short circuit inside the LCD screen, causing unnecessary loss. Cleaning the screen also requires regular quantification, and frequent scrubbing is also wrong, as it can also cause some adverse effects on the TV screen.
2) Put an end to some bad habits When not watching TV, please turn off the LCD screen (not limited to the remote control's closed state) to prevent the accumulation of dust; do not use your fingertips (usually hand pointing to the screen) or sharp objects Slide the LCD surface to avoid scratching the surface.
3) Keep the use environment dry and away from some chemicals Do not put the LCD TV in a damp place. If the moisture has entered the LCD TV, you must put it in a warm place to allow the moisture to evaporate. The current LCD screens are coated with a special coating on the screen to make the screen have a better display effect. The hair spray, alcohol, and anti-mosquito agents frequently used in summer are sprayed on the screen and dissolve the layer. The special coating causes damage to the liquid crystal molecules and even the entire screen, resulting in a shortened life span of the entire TV. Therefore, contact with moisture and chemicals is avoided as much as possible.
4) Safety Tips: Do not disassemble the body LCD TV is the new favorite of the recent home appliances, not only looks good, life expectancy is much longer than ordinary TV. However, LCD TVs can only be used without problems for a long period of time if they are well-maintained. Never disassemble the LCD TV. Because the CFL inverter in the backlight unit may still have a high voltage of about 1000V even after a long period of time, this high voltage can cause serious personal injury. So never try to disassemble or change the LCD display to avoid high voltage.
Relative maintenance and maintenance of LCD TVs is relatively simple, and it is advisable to prevent too much production from accumulating.
