LCD monitor maintenance and use skills

        While enjoying the high-end display of the LCD every day, don't forget the extremely important part of maintenance. Only when the LCD is well maintained can the LCD serve the user for a long time without any problems. If you already have an LCD or flat panel display, here are some tips that are very useful to you. It should be clear that the expensive LCD, as long as you follow some simple maintenance steps, can be loyal and long-term service, the only part of the LCD that is gradually consumed is the backlight of the display. After long-term use, you will find that the screen becomes dim or simply does not light up. In both cases, the LCD can be brought back to life and replaced with the new one.

1. Avoid burnout inside the screen

Remember, CRT monitors can burn out due to long-term work, as well as LCDs. So be sure to remember that if you don't use it, be sure to turn off the display or lower the display brightness of the display. Otherwise, it will cause internal burnout or aging. Once this damage occurs, it is permanent and cannot be recovered. So we must pay enough attention. In addition, if a fixed content is continuously displayed for a long time, it may cause some LCD pixels to overheat, thereby causing internal burnout.

To avoid this internal burnout, take the following measures when not in use:

1) Turn off the monitor when nothing happens; 2) Change the screen often at different time intervals Display on (eg running a screen saver)

; 3) Reduce the brightness of the display to a darker level; 4) Display an all-white screen content.

2. Keeping the humidity of the environment

All users who have suffered keyboard damage caused by spilling drinks onto the keyboard know this common sense. Do not let anything with moisture properties enter the LCD. If there is fog, wipe it gently with a soft cloth before turning on the power. If the moisture has entered the LCD, the LCD must be placed in a warm, dry place to allow the moisture and organics to evaporate. Applying power to an LCD containing humidity can cause corrosion of the liquid crystal electrode and cause permanent damage.

3. Cleaning the display surface properly

If you notice a smudge on the surface of the display, gently wipe it off with a soft cloth dampened with a little glass cleaner. Do not spill the cleaner directly onto the display surface. The cleaning agent entering the LCD will cause the screen to be shorted.

4. Avoid unnecessary vibrations

The LCD screen is very fragile, so avoid strong shock and vibration. The LCD is almost the most sensitive electrical device in the user's home or office. The LCD contains a lot of glass and sensitive electrical components that fall to the floor or other similar strong blows can cause damage to the LCD screen and the CFL unit. Also be careful not to apply pressure to the LCD display surface.

5. Do not disassemble

There is a rule that never remove the LCD. Even after a long period of shutdown, the CFL inverter in the backlight assembly may still have a high voltage of approximately 1000V, which can cause severe personal injury. So never attempt to disassemble or change the LCD display to avoid high voltages. Unauthorized repairs and changes can cause the display to temporarily or even permanently not work.

Nowadays, the market for liquid crystal displays has gone from hot spots to boiling points. The price of LCD monitors has plunged, making it easy for ordinary people to use the LCD screen of “noble consumption”. I believe that many friends have already purchased their favorite one. The next question is how to use and maintain, now I will talk about how to maintain our LCD monitor? What are the skills in terms of use?

6. Try to avoid displaying the same picture for a long time

Like the CRT display, the LCD display will also cause internal aging or burnout due to long-term work, especially bad in the long The same screen is displayed in time. If a fixed content is continuously displayed for a long time, it may cause some pixels to overheat, which may cause internal burnout and cause a bad point. This damage is irreversible and cannot be repaired. Therefore, we should pay attention when using it: when there is nothing to do, turn off the display; if it is only temporary, then choose the screen saver. Or the brightness of the display can be lowered a bit, or the screen can be completely white; but this only protects the LCD, the light tube at the back is still working, so I am more in favor of directly turning off the display, one hundred.

7, it is best to use the recommended best resolution

This is very different from CRT! The display of the traditional CRT display adopts the progressive scanning method, and there is no big problem in the resolution; the display principle of the liquid crystal display is completely different from the CRT display. It is a direct pixel-to-one display. The liquid crystal display operating at the optimal resolution passes the analog display signal outputted by the graphics card to a display signal with specific address information (the absolute address of the pixel on the screen), and then sent to the liquid crystal panel to directly display the signal. Some of the drive tubes added to the corresponding pixels are similar to the addressing and writing of the memory. If the DVI interface on the graphics card is directly output to the digital interface of the LCD, this new display mode does not have any pixel loss, and the signal output from the graphics card is perfectly displayed. However, when displaying a picture smaller than the optimal resolution, the liquid crystal display is displayed in two ways, one is a center display, for example, the liquid crystal display with an optimum resolution of 1024×768 is displayed at 800×600 resolution. Just use the 800×600 pixels in the middle to display the picture, and the surrounding is the shadow. This way, because the signal resolution is also one-to-one correspondence, the picture is clear, the only regret is that the picture is too small; the other is to expand The method is to enlarge the 800×600 picture to 1024×768 resolution by calculation. Since the processed signal does not correspond to the pixel one by one, although the picture is large, it is rather blurred. No matter which display method is not ideal, I highly recommend using the recommended maximum resolution!

8, put an end to some bad habits

The biggest bad habit is to often point to the screen by hand, the LCD monitor is very delicate, thousands of dollars of monitors do not move her casually. Generally speaking, the liquid crystal display is relatively light and accidentally knocked down, which is not a joke. Another point to note is that the power consumption of the liquid crystal display is relatively small, but the voltage of the transformer behind the liquid crystal display is still very high; pay special attention to safety, do not open the back cover of the display under power. Even after the power is turned off, the instantaneous voltage remaining is quite high, and the CFL transformer in the backlight unit still has a high voltage of about 1000V. In a liquid crystal display, the only part that is gradually consumed is the backlight of the display. After a long period of use, you may find that the screen is no longer so bright, or it is simply dark. This is not a serious problem, just change to a new background light. Note that DIYer is best not to handle the unusual products of LCD monitors. It is best to get a computer company or a professional repair station for repair. In short, don't re-demonize the use of CRT monitors on LCD monitors.

9, LCD screen cleaning

Baby LCD monitor has been used for a long time, the screen will become dirty, how to do? The correct way to clean it is to use a soft cloth dampened with a little glass cleaner to carefully wipe off the stains (use water without a detergent). Wipe hard when it is wiped, otherwise the monitor screen will be short-circuited. Do not allow water to flow into the interface between the screen and the screen frame during this process to avoid short-circuiting the display. Also, do not use a hard towel to scrub the surface of the screen to avoid rubbing the surface of the screen and affecting the display. Cleaning the display should be timed quantitatively, and frequent scrubbing is not correct, which will also have some adverse effects on the display. In addition, I have some secrets to deal with some oil stains that can't be wiped off. I use a transparent glue to stick it on the screen, and then peel it off. The place where the screen is pasted is very clean, and the oil stains are glued to the transparent glue. (For reference only!) 10: Don't use screen saver screen saver for LCD monitor

First, let's introduce the working principle of LCD (Liquid Crystal Display):

The core structure is composed of two pieces. The middle of the glass substrate is filled with moving liquid crystal molecules. The signal voltage directly controls the switching state of the thin film crystal, and then the liquid crystal molecules are controlled by the transistor. The liquid crystal molecules have obvious optical anisotropy, and can modulate the light emitted from the backlight tube to realize image display. A complete display consists of a number of pixels, each of which looks like a transistor that can be switched. This will control the resolution of the display. If an LCD has a resolution of 1024 x 768 (XGA), it represents both 1024 x 768 pixels for display. This means that the optimal resolution of the LCD is fixed, and why the refresh rate of the LCD is only 60 Hz.

So, an LCD that is displaying images, its liquid crystal molecules are always in the working state of the switch. For a LCD with a response time of 20ms, the liquid crystal molecules have been switched for a while. About a hundred times. The number of switching of liquid crystal molecules is naturally limited by the life, and the aging phenomenon of the LCD will appear, such as dead pixels. Therefore, when we stop the operation of the computer, the screen saver that displays the colorful repetitive motion on the screen undoubtedly makes the liquid crystal molecules still in the repeated switching state.

Because many screensavers nowadays have made it as an animation in order to improve their expressiveness and color change, some even 3D animations require the processing of graphics processors, so many huge The screensaver came into being. Such screensavers have become a big burden on the hardware of the computer, which has caused a serious deviation from the original intention of maintaining the computer. In addition, due to the need to cope with the ever-changing screens with rich color details, the CPU, hard disk and graphics card workload may be higher than usual applications. If you use a battery-powered notebook, such a screen saver will undoubtedly become a battery killer.

At the end of the day, monitors with different principles should use different maintenance methods. The best way to rest your LCD monitor is to turn off the monitor.

In short, in the use of the LCD monitor, we must take care of her, abandon the original use of CRT monitors, and keep the original good habits. Use the recommended best resolution for the best display. If the maintenance is better, a liquid crystal display can be used for more than ten years. Finally, I hope that you can use your LCD monitor to make your work and life more fun!
