Causes and preventive measures of electrostatic interference of LCD splicing screen
Electrostatic voltage
Electrostatic voltage is produced by the contact and separation of different substances, commonly known as triboelectrification. The voltage that can be generated depends on the characteristics of different materials. In the process of construction, the human body inevitably comes into direct or indirect contact with the relevant parts of the LCD splicing screen to generate static electricity, which leads to the appearance of strip waves during the power-on test.
Grounding anti-static
By grounding, static electricity can be conducted to the ground through wires, which is also the most direct and effective way to prevent static electricity. The main way is to connect a wire to the ground through the cabinet and LCD splicing screen.
Insulating tape dressing
In the center of the whole installation, the metal parts or power lines that can be directly contacted by the whole LCD splicing screen are wrapped with insulating tape to prevent static electricity.
The VGA cable and the power cable are arranged separately.
Please pay attention to the separate arrangement of VGA cable and power cord during construction, because VGA cable for LCD splicing screen generally has no shielding layer, and it is easy to generate static electricity if it is arranged together with power cord.
Building safety matters
Construction personnel should also carry out construction in accordance with relevant laws, regulations and safety matters, and try to release their own static electricity when contacting equipment to prevent static electricity from damaging the LCD splicing screen panel.
