How to extend the service life of LED display

The lifespan of LEDs is about 100,000 hours.

Based on the use of 10 hours a day, it can be used for about 27 years, although 100,000 hours is only a theoretical value, and not many people can use it to the end of life, usually the life of the LCD monitor is 50,000 hours, most of the time it is like dealing with CRT (big head) monitors, and it has been updated.

In fact, there is no need for the landlord to care too much about this specific use time, because the development and update cycle of the computer is very fast, but it is already quite long, and it will actually be discounted, even if it is an LCD display with a service life of only 50,000 hours.

Extending the service life of LED display is mainly to work maintenance.

1.It is required that the power supply is stable and the grounding protection is good, and it should not be used in harsh natural conditions, especially in strong lightning weather. To avoid possible problems, we can choose passive protection and active protection, try to keep the items that may cause damage to the full-color display screen away from the screen, and wipe as gently as possible when cleaning the screen to minimize the possibility of damage.

Turn off the LED display first.

Turn off your computer again.

2.Keep the humidity of the environment where the full-color led display is used for the large screen, and don't let anything with moisture properties enter your full-color led display large screen. Powering up a large full-color display screen that contains humidity can cause corrosion of the full-color display components, which can lead to permanent damage.

4.Switching sequence of led display:

A: Turn on the control computer first to make it run normally, and then turn on the large LED display screen.

B: It is recommended that the large LED screen rest time is greater than 2 hours a day, and the large LED screen screen should be used at least once a week in the rainy season. Generally, the screen is turned on at least once a month and lit for more than 2 hours.

5.**Do not be in the all-white, all-red, all-green, all-blue and other all-bright pictures for a long time, so as not to cause excessive current, excessive heating of the power cord, damage to the LED light, and affect the service life of the display.

6.Do not disassemble or splice the screen at will! The large LED full-color display screen is the most closely related to our users, and it is also very necessary to do a good job of cleaning and maintenance.

7.Exposure to the outdoor environment for a long time, wind, sun, dust, etc., is easy to be dirty, for a period of time, the screen must be dusty, Chen Zhi Technology recommends that you need to clean in time to prevent dust from affecting the surface for a long time.

8.The surface of the large screen of the LED display can be wiped with alcohol, or dusted with a brush or vacuum cleaner, and cannot be wiped directly with a damp cloth.

9.The large screen of the LED display needs to be checked regularly to see if it is working properly, whether the line is damaged, if it does not work, it should be replaced in time, and the line should be repaired or replaced in time if it is damaged. The internal circuit of the large screen of the LED display screen of Chenzhi Technology is forbidden to be touched by non-professionals, so as not to be electrocuted or cause damage to the line; If something goes wrong, have it serviced by a professional.

LCD displays have been widely used, and while we enjoy the unique high-end display effect of LCD every day, we should not forget the extremely important link of maintenance. Only when the LCD is well maintained can it serve the user for a long time without failure. Learn the following knowledge to lay a good foundation for your LCD maintenance.

Okay, let's start the maintenance of the LCD.

1.Avoid burning out the inside of the screen

As mentioned earlier, leaving the LCD on for a long time will reduce its lifespan. Therefore, in order to avoid the occurrence of such situations, the following measures can be taken when not in use: 1. Turn off the monitor when not in use;

2 Frequently change the content displayed on the screen at different intervals;

3. Reduce the brightness of the display to a darker level;

2.Maintain the warmth of the environment

Do not let anything with the nature of the liquid into the LCD, if the gas has entered the LCD, you must place the LCD in a warmer and drier place, so that the moisture and organic matter in it can evaporate, and then turn on the power. Powering an LCD with a high temperature can cause corrosion of the liquid crystal electrodes, which can cause permanent damage.

3.Avoid unnecessary vibrations

LCD can be regarded as the most sensitive electrical device in the dust, LCD contains a lot of glass and sensitive electrical components, so that the screen is very fragile, try to avoid strong shock and vibration, the impact of the strong brother He Lie is very easy to cause damage to the LCD screen and CFL unit. Be careful not to put pressure on the LCD display surface, and the bad habit of pointing in front of the screen must be corrected.

4.Do not attempt to disassemble the LCD

One rule is to never disassemble an LCD. Even after a long period of shutdown, the CFL inverter in the background lighting element can still carry a high voltage of about 1000V, which can cause serious personal injury. So never try to disassemble or alter the LCD display to avoid high pressure.

Unauthorized repairs and changes can result in the display temporarily or even permanently rendering it unfunctional. If there is a fault, it is recommended to take it to a professional repair station for repair.

5.It is usually best to use the recommended display resolution

The display principle of an LCD monitor is completely different from that of a CRT monitor. It is a direct one-to-one display of pixels. The LCD working at the best resolution converts the analog display signal output from the graphics card into a display signal with the absolute address of the pixel on the screen with specific address information, and then feeds it to the LCD board, and directly adds the display signal to the driver tube on the corresponding pixel on the screen.

For such point-to-point outputs, it is important to use the optimal resolution recommended by the display.

Summary: The maintenance of LCD display is mainly to protect it when it is usually used to achieve good results, and a little care in exchange for long-term and stable implementation.

If it is on the normal situation dao

If you work under a fixed voltage and current, you can use more than 60,000 hours according to the weight of 5% 10,000 hours of light decay, which only refers to the immortal lamp (not broken light). If it is used on the indicator light, it can be used for more than 100,000 hours and more than 20 years, but if it is used as a light source (such as LED bulbs and other lighting equipment), the life span is pitiful, and 60,000 hours is very long. It's about 7 years old, and even though it still glows, the light is weak (relatively speaking), and we say it's broken (it's just that the light is weaker, but it's still bright).

This is determined by the material used to make LED, generally a good LED is made of copper silver-plated bracket, a good light-emitting chip, welded with high-purity gold wire, a good sealant, if it is a white LED, it also requires the best phosphor, any of which will affect the quality of LED. Of course, it also affects its **.

Theoretically, it can reach 100,000 hours, but due to light decay and power supply, the current normal service life is 50,000 hours. If the power supply is very average, it can only be about 20,000 hours.

Compared with the radiation that CRT displays can't, liquid crystal displays have an innate advantage, and it basically has no radiation at all. For long-term computer workers, LCD monitors are very suitable for them. Although the LCD has low power consumption and no radiation, the lifespan of the LCD is quite short, only about 5 years, and the brightness will gradually decrease during use.

Compared with liquid crystal displays, CRT displays generally have a lifespan of 10 years, and the display effect will not be greatly affected.

However, the theoretical life of LED backlight display is as long as 100,000 hours, LED has many advantages such as high brightness, low energy consumption, no pollution, long time, suitable color temperature, bright colors, etc., which can be said to have great potential in the future lighting market and display backlight market.

I bought a laptop in 2011, the screen is an inch LED screen, the screen display color is no different from before, and the frequency of use is higher.

If the LCD screen is divided from the backlight, it is generally divided into two kinds, LCD and LED, generally speaking, the material of the LCD panel of the LCD screen is about the same, relatively speaking, LED is the replacement product of LCD, LCD is to provide a light source with the usual similar fluorescent tube, and LED is different, it may be a LED light board or a light bar, LCD general life is about 5 years, and LED LCD screen will generally be more than ten years, of course, it also depends on your specific use time, Both LCD and LED are measured in hours.

I used it for 7 years, my classmates used it for 3 years, and it depends on this, anyway, it's an average of 5 years.

1.The theoretical lifespan of LEDs in a greenhouse is 10W hours.

2.is really exposing the wind and sun to other factors, in fact, the real effect is about 5 years.

LED series products are all backlit LCD screens. The LED LCD screen can dynamically adjust the brightness of the LED in its corresponding position according to the brightness and darkness of the image and the surrounding color, resulting in the dynamic conversion of the contrast of the area according to the requirements of the picture, so that the contrast of each display part of the entire LCD screen is not the same, and the effect will be much better.

The theoretical life span is 5 years, and the actual life expectancy is a little longer.

In our world, we never give a medal to a sad laggard.

The LCD life is reduced by 3dB according to the luminous value, which is 3000-8000 hours and 50000 hours for LED depending on the brand.

Teach you how to extend the service life of LED electronic display.

First, pay attention to the problem of switching on and off the LED large screen.

Switch sequence: When turning on the display: turn on the computer first, then turn on the screen. When turning off the display: turn off the screen first, then turn off the computer (turning off the computer first and not turning off the display screen will cause the screen to appear high bright, burn the lamp, and the consequences will be serious.) )

2. Precautions for software operation and use.

Check for viruses regularly and delete irrelevant data.

Master the setting of control parameters and the modification of basic data presets.

Proficient in installation methods, original data recovery, and backup.

3. Precautions for changes and changes in the control system part of the display screen.

The power cord of the computer and control part cannot be reversed, and should be plugged in strictly according to the original position. If there are peripherals, after the connection is completed, the case should be tested to see if it is live.

When moving control equipment such as computers, check whether the connection wires and control board are loose before powering on.

The position and length of communication lines and flat connection lines cannot be changed at will.

If it is found that there is an abnormality such as short circuit, tripping, wire burning, and smoke after moving, it should not be repeatedly powered on for testing, and the problem should be found in time.
