What is the cause of static electricity in LED rental screen?
For LED rental screen, many people may not know much about it. LED rental screen as a custom die-casting aluminum box design, light, thin, fast installation for its important characteristics. BoxThe thinness and lightness of the body and the ability to be quickly installed, removed and transported make it suitable for large area rentals as well as fixed installation applications. However, inLED rental screenThe use of the process, sometimes static electricity, what is the cause of this? The following Vishay editorial will address this issue to introduce.
Electrostatic voltage is generated by different kinds of substances touching and separating from each other. The onset of the voltage depends on the characteristics of the materials themselves in conflict with each other. Because the LED rental screen in the practice of production process is mainly the human body and the relevant meta-equipment direct touch and direct touch static electricity, and therefore based on the combination of its relevant features to take a certain approach.
Static electricity in the LED rental screen production process damage, if the production of any part of the neglect of anti-static, it will cause electronic equipment failure and even make it damaged. When the semiconductor equipment alone or loaded into the circuit, even if there is no electricity, because static electricity may also form permanent damage to these devices.LED rental screen is a semiconductor product, if the LED two pins or more pins between the voltage beyond the breakdown strength of the component dielectric, it will form damage to the components. The thinner the oxide layer, the greater the sensitivity of the LED rental screen and driver IC to static electricity. Both will occur severe leakage pathway, and then form a devastating damage.
Another reason is because the node temperature beyond the melting point of semiconductor silicon (1415 ℃) caused by. Even if the voltage is lower than the breakdown voltage of the medium, will also have this problem. LED rental screen itself or drive circuit in the IC by the impact of static electricity, may not immediately present functional damage, so the impact on the life of the display are fatal. Therefore, like the same regular LED rental screen manufacturers with the same electronics in the production process will be layers of control, and then ensure that the production of LED rental screen quality is certainly qualified.
The above about the LED rental screen static electricity what is the reason for you to share here, I hope this article is helpful to you. If there is anything you do not understand you can leave a message to the editor, we will answer for you as soon as possible.
