Knowledge for Anti-static design

Static electricity is a relatively static charge (Electro-Static), which usually refers to the positive and negative charges on the surface of an object caused by the friction between different objects.

Electrostatic discharge refers to the transfer of electrostatic charge between objects caused by direct contact or electrostatic induction of objects with different static electricity (Electro-Static-Discharge).

Usually refers to the phenomenon of discharging after the energy of the electrostatic field reaches a certain level, breaking down the medium in between.

Causes of static electricity in bus led destination sign

From a microscopic point of view, according to the theory of atomic physics, matter is in an electrically balanced state when it is electrically neutral. Due to the contact between atoms of different substances, the gains and losses of electrons are generated, which makes the substances lose their electrical balance and generate static electricity.

From a macro perspective, the reasons are: friction between objects generates heat, which stimulates electron transfer; contact and separation between objects produce electron transfer;

electromagnetic induction causes an unbalanced distribution of charges on the surface of an object; the combined effect of friction and electromagnetic induction.

Specific anti-static measures for bus destination led display sign
