LCD screen manufacturers tell about the use of liquid crystal display module to pay attention to what the details, now a lot of places will use LCM-LCD module this new product, I believe we understand it also have a certain understanding. In order to ensure that you buy the product to play the product should have the performance, you use my company's LCD module should pay attention to the following matters, in order to ensure that the LCD module to bring you the best display, the following Xiaobian To bring you a deep understanding of the use of liquid crystal display module to pay attention to the details.
First, the anti-static: the module control, drive voltage is very low, micro-power CMOS circuit, easily susceptible to static breakdown, static breakdown is a repair can not be damaged, and the human body sometimes produce up to tens of volts High voltage static electricity, so in the operation, assembly and use of liquid crystal display module should be extremely careful to prevent static electricity. to this end:
1. If you have to be in direct contact, keep the body at the same potential as the module or ground the body well;
2. The soldering iron used for welding and the electric tools for operation must be well grounded without leakage;
3. Do not hand to touch the outside lead, circuit board circuit and metal frame;
4. Do not use a vacuum cleaner for cleaning, because it will produce a strong static;
5 .. air drying, will also produce static electricity, therefore, the work room humidity should be RH60% or more;

Second, the welding: In the welding module outside the lead, the interface circuit should be the following procedures to operate.
1. The tip temperature is less than 280 ° C.
2. Welding time is less than 3 ~ 4s.
3. Welding materials: eutectic, low melting point.
4. Do not use acid flux.
5. Repeat the welding not more than 3 times, and each need to be repeated 5 minutes interval.
Third, the industrial flat panel LCD screen assembly operation LCM-LCD module Note:
1. Do not modify the machined PCB board shape, mounting holes, lines and other parts.
2. The module is carefully assembled after assembly, do not arbitrarily self-processing, dressing.
3. Metal frame claws are not free to twist, disassemble.
4. Do not modify the conductive tape.
5. Do not touch, throw, bend, twist the module.
6. Do not modify any internal support; if necessary, should be given to professionals.
Handle the protective film: in the installed module finished table and affixed with a protective film, is to prevent customers in the assembly when the stain is not the surface of the screen, the customer before the end of the assembly is best not to tear, so as not to get dirty or damaged LCD screen surface. If you encounter bad products, the same after the demolition, still put the protective film back to prevent scratching the LCD screen surface.
