The liquid crystal display has a thin body and saves space; it saves electricity, does not generate high temperature; low radiation, benefits health; the picture is soft and does not hurt the eye, etc. Now it is widely used by everyone, then how long do you know about the life of the liquid crystal display? The following small series will introduce how long the life of the LCD monitor is, I hope to help everyone. The following is an introduction to how long the life of a liquid crystal display is. 1, about 50,000 hours, mainly based on the brightness down to half of the factory value specifications to define the life. 2, other factors (1) CCFL (cold cathode lamp) of the backlight is prone to aging, air leakage, broken and so on. (2) The screen drive circuit is prone to electrical defects such as ICs and capacitors due to electrical components. (3) The display screen is prone to defects such as bright spots and lines due to static electricity and foreign matter. 3, the aging of the lamp is mainly based on the brightness and color to distinguish, the aging brightness will be reduced, the white light color is yellow. The aging of the LCD screen is usually difficult to distinguish, and there are serious dark spots or line defects. 4, the LCD screen will age, because there are also semiconductor components inside, and the LCD will also age. 5, the two are separate, but must not be repaired by themselves, because the assembly and disassembly of the screen and backlight are carried out in a clean room and anti-static environment, the general environment is not acceptable, and the replacement of the lamp should be backlit It is also removed, and it may cause damage to the optical material without being removed. Can be found by the manufacturer to repair, only the lamp is not very expensive, but if the optical material inside is broken, it is more expensive. Other knowledge: First, the life of liquid crystal display LCD display power consumption is small and no radiation, for long-term use of computer workers, liquid crystal display is very suitable. The shortcoming is that the life of LCD monitors is quite short. The current life expectancy of most LCD monitors on the market is 20,000 to 30,000 hours (it is said that ViewSonic LCD monitors can reach 50,000 to 60,000 hours). In other words, if you turn it on 24 hours a day, you can only use 833 to 1250 days, less than 3.5 years, and the brightness will gradually decrease during use. Compared with liquid crystal displays, CRT monitors generally last for 10 years, and the display effect is not affected too much. However, for IT products, it has been good to use for 5 years, and it should be replaced. The core components of the liquid crystal display are the liquid crystal layer and the two polarizing plates and the backlight assembly. The main components of the backlight assembly are the backlight tube and the light guide plate. The life of the backlight tube is mainly determined by the life of the backlight tube. After the deadline, the backlight tube will be aging, and the brightness will decrease. When the brightness of the tube is attenuated to 50%, the usage time is defined as the lamp life. When the brightness of the LCD monitor is reduced to a certain time, a less noticeable scan line will appear because the display automatically reduces the frequency of the lamp. Second, the resolution resolution of a liquid crystal display refers to the number of pixels displayed per unit area. The LCD panel is like a small door arranged to let the light pass through. The pixels that the LCD screen can represent are determined by the number of “small doors” on the unit area, which determines the LCD. The physical resolution of the display is fixed. In a normal CRT display, as long as the deflection voltage of the electron beam is adjusted, different resolutions can be changed. Regardless of whether it is an LCD liquid crystal display or a general CRT display, resolution is the main parameter. The display must be able to support the resolution required to apply the software and hardware, but the LCD only supports the so-called true resolution, which can be compared to the highest resolution of a typical CRT display, and the best image can be displayed only at the real resolution. The LCD display presents two modes of presentation in a lower resolution display mode: the first is a centered display. The whole picture looks like the image is centered and zoomed out, and the outer periphery of the display pixel is surrounded by a shadow; the second is an extended display. Although there is no shadow edge wrapping, the sharpness is affected. Therefore, when choosing a liquid crystal display, it is not the higher the resolution, the better the original resolution of the application software and hardware used to ensure support. As a general user, it can support 1024*768. Third, the resolution and LCD monitor life relationship The default resolution of the ordinary 17-inch LCD monitor is 1280 * 1024, such as for 1024 * 768 (resolution of algorithm simulation), in addition to affecting the clarity, has no effect on the life. Fourth, the use of liquid crystal display precautions 1, it is recommended to work in normal temperature /normal humidity environment, high temperature /high humidity will affect the life of the liquid crystal display. 2. Intense temperature fluctuations can affect the performance of liquid crystal displays, especially low temperatures can affect brightness and response time. It is recommended to work in a stable and clean environment, and dust can cause internal circuit failure. 3. Do not let liquid splash into the inside of the monitor. If you need to clean, turn off the power, spray the cleaner on a soft cloth and wipe gently. 4. The liquid crystal display is a glass product, and should avoid collision and vibration when moving. 5, the surface of the liquid crystal display has a multi-layer film, it is strictly prohibited to use a sharp marker. 6. It is strictly forbidden to disassemble the LCD monitor at will. If it is faulty, please ask the professional to repair it. 7. Displaying the fixed screen for a long time will reduce the brightness and increase the image retention. It is recommended to use the screen saver. 8. Do not turn off the monitor and unplug the power cord for a long time. This article comes from [System Home] www.xp85.com
