While enjoying the unique display effect of LCD every day, don't forget the extremely important part of maintenance. Only when the LCD is well maintained can it serve users for a long time without failure. Here we invited Philips LCD display engineers to introduce us to some precautions for LCD displays.

I've heard that CRT monitors have phosphor burnouts, do LCDs have them? CRTs can burn out due to long-term operation, and this is also a problem for LCDs. So be sure to pay attention to turn off the display if you are not using it, or reduce the display brightness of the display.

Otherwise, it will lead to internal burnout or aging over time. This damage, once it occurs, is permanent and irreparable. In addition, if a fixed content is displayed continuously for a long time, it may cause some LCD pixels to overheat, which may cause internal burnout.

I've heard that LCD is very demanding on air humidity, is there such a thing? This statement is inaccurate, generally the humidity is kept between 30% and 80%, and the display can work normally, but once the indoor humidity is higher than 80%, condensation will occur inside the display. The internal power transformer and other coils are also prone to leakage when wet, and may even cause a short circuit in the wiring.

Therefore, the LCD display must pay attention to moisture-proof, and the display that has not been used for a long time can be powered on regularly for a period of time, so that the heat generated by the display when it is working will drive out the moisture in the machine. My LCD screen is dirty, how do I clean the surface of the display? If you find that there are stains on the surface of the display, you can gently wipe it off with a soft cloth with a little water, do not spill water directly on the surface of the display, water entering the LCD will cause a short circuit on the screen.

Is there anything else I need to pay attention to when using LCD monitors? LCD screens are very fragile, so avoid strong shocks and vibrations, LCDs contain a lot of glass and sensitive electrical components, falling to the floor or other similar strong blows can cause damage to the LCD screen and some other units. Also be careful not to put pressure on the LCD display surface.

There is one rule: never disassemble an LCD. Even after being turned off for a long time, the CFL inverter in the background lighting component can still carry a high voltage of about 1000V, which can cause serious personal injury.

So never try to disassemble the LCD display to avoid high pressure. Unauthorized repairs and changes can result in the display temporarily or even permanently rendering it unfunctional. So when your hands and feet are really idle, don't touch the delicate and dangerous LCD!
