When the security system set up basic installation is complete, the number of projects after installing LCD wall during debugging screen will generate multiple lines ripple. Do not worry, here we will conduct a detailed analysis
Symptoms: how the screen lines ripple
Causes: static actions.
Static electricity causes:
From the micro to say, according to the theory of atomic physics, electrical power balance in the neutral state when substance, since the electronic contact with the pros and cons of different substances produced by electrons, so that the material loss of power balance, the phenomenon of static electricity.
From a macro perspective, the object between friction and heat, to stimulate electron transfer, contact and separation between objects generate electron transfer, electromagnetic induction caused by uneven distribution of surface charge, friction and the combined effect of electromagnetic induction.
