There are several main reasons for the liquid leakage of the LCD liquid crystal screen

The LCD liquid crystal display uses two polarized materials, and between them is a liquid crystal crystal solution. Many users will encounter the problem of liquid leakage from the LCD screen during use, and most users have no clue about it and don't know what to do. Today, the editor will popularize the repair problem of LCD screen leakage for everyone, and teach you how to maintain the LCD screen by the way.

The main reasons for liquid leakage on the LCD screen are as follows:

Damaged seal: it will mainly appear on the four edges of the screen. If acidic and alkaline liquids such as beverages, juices, soft drinks, tea, etc. accidentally flow into the edge of the screen from the outside to soak, the sealant will be damaged, and the LCD inside will be damaged. Leakage. If there is a problem with the sealant in the production process of the screen, such a failure will also occur.

The surface of the screen is damaged by external force: it is generally concentrated in the middle of the screen, and obvious traces of glass cracks can be seen. At this time, press the leaking part with your hand, and you can see that the trajectory of the liquid crystal force movement moves along the direction of the crack.

LCD liquid crystal screen leakage repair

Physical phenomenon: There are very obvious blocky black spots on the surface of the notebook or LCD (in the case of power on), or there are patches of uneven light and shade (in the case of no power on) and there are cracks at the same time. Some LCD screens are not subjected to too much external force. Although the liquid crystal screen leaks, there is no crack on the surface. This fault phenomenon is not easy to find, especially when the LCD screen is powered on and does not light up. After the liquid crystal display breaks and leaks, the image can still be displayed. At the same time, after the liquid crystal screen leaks, the power-on test machine will not produce new faults, so we don't have to worry about it.

Causes and repairs: The liquid crystal display is squeezed or impacted by external force, causing the liquid crystal screen to break and leak. Solution and maintenance cost: This type of failure is a very clear man-made physical damage, because the display is accidentally squeezed or pressed by a child's finger, or it may be caused by impact during transportation. The maintenance cost of damaged LCD screen is relatively high. If the LCD screen is damaged, it is generally not repaired, because the cost of replacing the LCD screen is close to the cost of an LCD monitor of the same model.

Daily maintenance:

1. If the LCD monitor is not used for a long time, please turn off the power or set the host to power saving mode.

2. Minimize the use of high-brightness all-white screens for a long time as much as possible. These two points can slow down the aging of the lamp tube and prolong the service life of the display.

3. Keep the storage and use environment clean, and clean the screen surface correctly.

4. Keep away from high temperature and high humidity environment.

5. It is strictly forbidden to pour liquid on the screen and the machine.

6. It is strictly forbidden to squeeze the surface of the collision screen.

7. Avoid unnecessary vibration.

8. Do not disassemble or assemble by yourself.
