Precautions for using LCD screen Precautions for using LCD screen 1. Handle the protective film: There is a protective film on the surface of the finished module to prevent customers from staining the display surface during assembly. Therefore, please do not remove it before the assembly of the whole machine is completed to avoid dirtying or damaging the display surface. 2. Install a gasket: It is best to install a gasket of about 0.1 mm between the module and the front panel. The panel should also be kept flat to avoid distortion after assembly and improve its vibration resistance. 3. Strictly prevent static electricity: The control and drive circuits in the module are low-voltage, micro-power CMOS circuits, which are easily broken down by static electricity. Static electricity breakdown is an irreparable damage, and the human body sometimes generates high-voltage static electricity of up to tens of volts or hundreds of volts. Therefore, you should be extremely careful in operation, assembly and use to prevent static electricity. To this end: 1. Do not touch the external leads, circuits on the circuit board and metal frame with your hands; 2. If direct contact is necessary, keep the human body and the module at the same potential, or ground the human body well; 3. The soldering iron used for welding and the electric tools used for operation must be well grounded without leakage; 4. Do not use a vacuum cleaner for cleaning, because it will generate strong static electricity; 5. Dry air will also generate static electricity, so the humidity in the workplace should be above RH60%; 6. Be careful when taking out or putting back the packaging bag or moving the position to prevent static electricity. Do not change the packaging or discard the original packaging at will. IV. Precautions during assembly operation: 1. The module is carefully designed and assembled, so do not process or trim it at will; 2. The metal frame claws must not be twisted or disassembled at will; 3. Do not modify the shape, assembly holes, circuits and components of the PCB board at will; 4. Do not modify the conductive tape; 5. Do not modify any internal bracket; 6. Do not touch, drop, bend or twist the module. 5. Welding: When welding the external leads and interface circuits of the module, the following procedures should be followed. 1. The temperature of the soldering iron tip is less than 280°C; 2. The soldering time is less than 3-4s; 3. Soldering material: eutectic, low melting point; 4. Do not use acidic flux; 5. Repeat...
