Color liquid crystal module, because the circuit in the module, the drive control is low voltage, and the circuit with micro power consumption is very easy to be broken down by static electricity.
The normal human body sometimes generates high-voltage static electricity of up to tens of volts or hundreds of volts. Be extremely careful in operation, assembly, and use, and it is necessary to strictly prevent static electricity.
Do not use a vacuum cleaner for cleaning, because it generates strong static electricity.
Dry air will also generate static electricity, so the humidity in the workplace should be above RH60%.
The ground, workbenches, chairs, shelves, carts and tools should all be in resistive contact to keep them at the same potential.
Take out or put it back to the moving position of the packaging bag, and be extra careful not to generate static electricity, and do not change the packaging or discard the packaging bag at will.
Electrostatic breakdown is an irreparable damage, so be careful not to be careless.
Do not touch the outer leads on the circuit, the circuit and the metal frame on the circuit board with your hands.
If direct contact is necessary, keep the human body and the module at the same potential.
The soldering iron used for soldering must be well grounded and there is no leakage.
The power tools used for operation must be well grounded and there is no leakage.
