Methods for repairing LCD liquid leakage
LCD screens use two polarizing materials with liquid crystal solution between them. Many users encounter the problem of LCD liquid leakage during use, and most of them have no idea how to deal with it. Today, I will explain the repair of LCD liquid leakage and also teach you how to maintain LCD screens.
The main causes of LCD liquid leakage are as follows:
Damaged seal: This mainly occurs at the four edges of the screen. If acidic or alkaline liquids such as beverages, fruit juice, soda, or tea accidentally seep into the edges of the screen, it will damage the sealant and cause liquid crystal leakage. If there is a problem with the sealant during the production process, the same fault may occur.
Surface damage due to external force: This is usually concentrated in the middle of the screen, where obvious glass cracks can be seen. When pressing the leaking area with your hand, you can see the trajectory of the liquid crystal moving along the crack.
Repairing LCD liquid leakage:
Physical phenomenon: There are very obvious block-shaped black spots (when powered on) or uneven bright and dark patches (when powered off) on the surface of laptops or LCD monitors, and there are also cracks. Some LCD screens may leak liquid without surface cracks due to minor external forces, and this fault may not be easily noticeable, especially when the LCD monitor does not turn on after being powered on. After the LCD display screen is cracked and liquid leaks, it can still display images. At the same time, there will be no new faults when the powered-on test is performed after the LCD screen leaks, so there is no need to worry.
Causes and repair: LCD displays may experience liquid leakage due to external pressure or impact, resulting in screen cracks. Solution and repair costs: This type of fault belongs to clear physical damage caused by external force, such as accidental squeezing or finger pressing on the monitor, or impact during transportation. The repair cost for a damaged LCD screen is relatively high. For LCD monitors, if the LCD screen is damaged, it is generally not recommended to repair it because the cost of replacing the LCD screen is close to the cost of a new monitor of the same model.
Causes and daily maintenance of LCD liquid leakage repair:
Daily maintenance:
If the LCD display is not used for a long time, please turn off the power or set the host to power-saving mode.
Try to minimize the use of high-brightness all-white screens for a long time. These two points can slow down the aging of the backlight lamp and extend the life of the display.
Keep the storage and usage environment clean and clean the screen surface correctly.
Stay away from high-temperature and high-humidity environments.
Do not spill liquid on the screen and the machine.
Do not squeeze or collide with the screen surface.
Avoid unnecessary vibrations.
Do not disassemble by yourself.
