How to solve the interference caused by static electricity to LCD splicing screen?

Browse: June 2020: June 2020

In the cold and dry winter, people often encounter this phenomenon in their daily life: when they take off their clothes and sleep in the dark, they often hear the action in the dark, accompanied by blue light. When they shake hands, their fingers just touch, and suddenly feel the pricking fingertips, which is very shocking. When you comb your hair in the morning, it tends to float. The more you break it, the more you pull the door handle, the faucet will "shock" and often send out "Pa, Pa" action, which is the static electricity in the human body. "The so-called static electricity is a charging stop or invalid, static electricity can be said to be everywhere LCD splicing screen In the operation, static electricity will also form a certain interference.

Insulation, 1
The so-called insulation is as far as possible paste LCD connector screen and metal and power connection, to avoid static electricity.
2. Separation of lines and lines
When the connection is separated, the VGA line is separated from the power line, because the ordinary VGA line has no shielding layer, so it is easy to generate static electricity with the power line.
3. Grounding
The so-called grounding connection is to directly release static electricity to the ground through the cable, which also directly and effectively prevents static electricity.

Six advantages of Weikang LCD splicing screen
Static electricity is a natural law, we can not completely eradicate it, so what we can do is to minimize the damage to the large screen. Usually, in the process of debugging and using LCD splicing screen, when several lines appear on the screen, most of the time is caused by electrostatic interference; electrostatic adsorption dust, reduce insulation resistance, discharge damage components and discharge. Electromagnetic interference is destroyed, and many of these damages are long-term and random. When the static interface of the system is relatively large, the interface of the system may be seriously damaged. Large screen other LCD splicing screens may exhibit abnormal behavior, such as unstable signal transmission and screen glare in client applications. In addition to the flexibility of line interface and cable manufacturing technology, it can also be static interference.
If we don't supply the high-voltage resistor in the machine room, we should pay attention to the high-voltage components such as the capacitor in the high-voltage cabinet.
