In our living space, static electricity is present everywhere. Electrostatic voltage is easily capable of rising to tens of thousands of volts, and even hundreds of thousands or even millions of volts. So what risks does static electricity pose to LCD screens?
The first thing you should be aware of is that the majority of LCD Ltd.'s clients are manufacturers of industrial goods, and many of these goods require an electrostatic test after they are complete. The use of static electricity is crucial for industrial goods.
In actuality, the LCD display screen itself has a low level of static electricity resistance. Even the greatest LCD screen material cannot resist the electrostatic gun's direct discharge.
The best thing we can do to prevent damage to the LCD display screen before installation is to utilize techniques that minimize the development of static electricity during the manufacture process.
To prevent static electricity produced by the human body or generated during movement, the operators in the LCD production workshop put on anti-static clothing and shoes and discharge static electricity before entering the work area.
It is strictly prohibited for any part of the human body to come into direct contact with the liquid crystal display, the interface in the module, the pins, or any other metal conductive parts during the client's assembly process. The operator is also required to operate in strict accordance with the regulations.
Maintain the production site space at a comfortable temperature and humidity level as well. The humidity is regulated at around 60%, while the temperature is kept at roughly 28 degrees. As a result, the entire area creates a discharge body, with the air serving as the electrical conductor. In this way, the static electricity produced by the various frictional actions in this area will be effectively and promptly discharged without building up.
In actuality, the layer of plastic film that covers the LCD display screen as it leaves the manufacturer serves primarily as protection against contamination and scratching caused by fingers in contact with dirt and oil during transportation and use.
It is the same whether it is a monochrome LCD display screen, LCD module, or TFT color screen, but when using it, we are more interested in the clarity of the display. Despite some transparency, the plastic coating will surely have an impact on the screen. show impact.
The LCD display screen's protective layer, on the other hand, serves solely to shield the LCD display screen till the installation is finished. In terms of durability, it cannot compare to the unique protective film. In most cases, after extensive use, there will be bubbles, warping, etc.
Other than mobile phones, LCD display panels are typically found in equipment goods. Since people rarely stare at these screens, it is preferable to improve the display effect rather than preserving the protective layer, which is prone to warping.
Therefore, to improve the clarity and dependability of the display content, we should without hesitation remove the protective film from the LCD display screen once it has been mounted and put to use. Throughout the lifespan of a typical LCD display, this protection is not necessary.
