How to Protect the LCD Display Screen?

1. The harm of static electricity to the LCD display screen

Static electricity is everywhere in our living place. Electrostatic voltage can easily reach tens of thousands of volts, even as high as hundreds of thousands or hundreds of thousands of volts. So what are the hazards of static electricity to LCD display screens?

The first thing you need to know is that most of the customers of LCD Ltd. are industrial products, and many industrial products need to do an electrostatic test after they are finished. Static electricity is very important for industrial products.

In fact, the LCD display screen itself is not very resistant to static electricity. Even the best LCD display screen material cannot withstand the direct discharge of the electrostatic gun.

What we can do is to avoid the generation of static electricity as much as possible in the process of production and use to prevent damage to the LCD display screen before installation.

Therefore, in the LCD production workshop, the operators wear anti-static clothing and anti-static shoes, and discharge static electricity before entering the site to avoid static electricity generated by the human body or generated during movement.

However, during the assembly process of the client, the operator is also required to operate in strict accordance with the regulations, and it is strictly forbidden for any part of the human body to directly contact the liquid crystal display, the interface in the module, the pins and other metal conductive parts.

In addition, maintain a reasonable temperature and humidity in the production site space. The temperature is controlled at about 28 degrees, and the humidity is about 60%. In this way, the entire space forms a discharge body with air as the electrical conductor. In this way, the static electricity generated by various frictional movements in this space will be released in a timely and effective manner without accumulating.

2. Does the original film of the LCD display screen need to be retained?

In fact, when the LCD display screen leaves the factory, the layer of plastic film on the LCD display screen is more to prevent the screen from being polluted and scratched by fingers touching dust and oil during transportation and use.

Whether it is a monochrome LCD display screen, LCD module, or TFT color screen, it is the same, but we are more concerned about the clarity of the display when using it. The plastic film has a certain degree of transparency, but it will undoubtedly affect the screen. show effect.

At the same time, the protective film of the LCD display screen itself is only to protect the LCD display screen before the installation is completed. It cannot be the same as the special protective film in terms of longevity. Usually, after a long time of use, there will be bubbles, warping, etc. 

Besides mobile phones, other LCD display screens are mostly used in equipment products, and they rarely stare at them, so instead of keeping the protective film that is easy to warp, it is better to give the equipment a better display effect.

Therefore, after the LCD display screen is installed and put into use, we should unhesitatingly remove its protective film to make the display content clearer and more reliable. Such protection is not required during the life of a normal LCD display.
