How long is the life of a liquid crystal monitor?

Liquid crystal display with thin fuselage, save space; do not produce high temperature, low radiation, good health, the screen is not to hurt the advantages of the eye is now widely used, that everyone on the life of the liquid crystal display is not understand how long, the following small series to introduce the life of the LCD display is how long, 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 according to the brightness down to the factory value of the specification of half the definition of life.

2. Other factors

(1) Backlight CCFL (cold cathode lamp) is prone to aging, air leakage, broken and so bad.

(2) Screen drive circuit because of electrical components prone to poor electrical, such as IC, capacitance and so on.

(3) screen due to electrostatic, foreign bodies, such as easy to appear bright dark spots, lines and other defects.

3, lamp Aging is mainly based on the brightness and color to distinguish, the aging brightness will be reduced, white light color yellow. LCD screen aging is often difficult to distinguish, serious will have bright dark spots or line defects appear.

4, the LCD screen will be aging, because there are semiconductor components, and the LCD will also be aging.

5, the two are separate, but must not repair themselves, because the screen and backlight assembly and dismantling is in the clean room and anti-static environment, the general environment is not, and the replacement of the lamp to the backlight will also be removed, no demolition may cause optical material damage. can find manufacturers to repair, only to change the tube is not very expensive, but if the optical material inside the damage can be more expensive.

Other knowledge:

First, the Life of LCD display

LCD display power Consumption is small and no radiation, for the long-term use of computer workers, liquid crystal display is very suitable. Insufficient is, the life of the liquid crystal display is quite short, now the market most of liquid crystal display's nominal service life is 2~3 million hours (it is said that ViewSonic Liquid crystal display can reach 5~6 million hours). That is, if you turn on 24 hours a day, you can only use 833-1250 days, less than 3.5 years, and in the course of use, the brightness will gradually weaken. Compared with the liquid crystal display, CRT display life is generally up to 10 years, and the display effect will not be affected too much. However, for it products, it is good to use 5 years, it should be replaced.

The core component of the liquid crystal display is the LCD layer and the top and bottom two pieces of polarizer and backlight components, backlight components of the main components are backlight lamp and guide plate two parts, the life of the main decision is the life of the backlight lamp, after reaching a certain period of time, backlight lamp will appear aging, brightness with the decrease, when the lamp brightness attenuation to 50% When the use of time is defined as lamp life.

LCD display brightness reduced to a certain time, there will be less obvious scan line, this is because the display automatically reduces the frequency of the tube.

Second, the resolution of the liquid crystal display

Resolution refers to the number of pixels per unit area displayed. LCD panel as if arranged a small door, used to allow light through the LCD screen can represent the pixel is the unit area of the "small door" number to determine, which determines the physical resolution of the liquid crystal display is fixed. The ordinary CRT display, as long as the adjustment of the electron beam deflection voltage, you can change the different resolution.

Resolution is the main parameter, whether it is an LCD or a general CRT display. The display must be able to support the application of hardware and software required resolution, but the LCD only supports the so-called real resolution, can be likened to the general CRT display the highest resolution, only the real resolution to show the best image.

The display mode of the LCD display with lower resolution is presented in two ways: the first is centered. The whole picture looks as if the image is centered, and the outer edge of the display pixel surrounds the shadow, and the second is the extended display. Although there is no shaded edge wrapping, the sharpness can be affected. So when choosing a flat panel monitor, it is not as high as the resolution that you want to be able to support the original resolution of the application software and hardware you are using. As a general user, can support 1024*768 enough.

Three, the resolution and the life of the liquid crystal display

Ordinary 17-inch LCD default resolution is 1280*1024, such as for 1024*768 (algorithm simulation of the resolution), in addition to affect the definition, the life has no effect.

Four, the use of liquid crystal display notice

1, recommended at room temperature/Chang environment work, high temperature/high humidity will affect the life of LCD display.

2, the intense temperature fluctuation will affect the performance of the liquid crystal display, especially the low temperature will affect the brightness and response time. Recommended to work in a smooth, clean environment, dust will cause internal circuit failure.

3, do not let the liquid splash into the monitor inside, if need to clean, please turn off the power, the detergent spray on the soft cloth and then gently wipe. 4, liquid crystal display is glass products, moving should avoid collision, vibration.

5, liquid crystal display surface has multilayer film, is strictly prohibited with sharp device engraved.

6, forbid to disassemble the liquid crystal display at will, in case of trouble must please professional maintenance.

7, long time display fixed screen, will make the brightness drop, image retention phenomenon increase, we recommend the use of screen saver program.

8, long time do not need to turn off the monitor power, unplug the power plug.

The above is small series for everyone to clean up the life of the liquid crystal display is how long, I hope that more and more computer users have reference!
