What Are The Specifications For The LCD Module Assembly?

- Aug 14, 2018-




The LCD module is now widely used and used in many high-tech industries. So since it will be used so widely, everyone will want to do it right when they use and install it. This will make the LCD module work better. The LCD module is simply a screen + backlight + PCB + iron frame. The liquid crystal display module is a component that assembles the liquid crystal device with the control, the drive circuit, and the circuit board PCB. It can be connected directly to a computer. When using this kind of liquid crystal module, in addition to the precautions when using the general liquid crystal display device, pay attention to the following items during assembly and use:


1. Adding a pad: It is better to install a pad of about 0.1MM between the module and the front panel. The panel should also remain absolutely flat. One guarantees no distortion force after assembly. And improve seismic performance.


Second, the treatment of the protective film on the surface of the finished module liquid crystal display device has a protective film to prevent contamination of the surface during assembly. Do not remove it before the end of the assembly to avoid soiling or staining the display surface.


Third, the control and drive circuit in the anti-static module is a low-voltage, micro-power CMOS circuit, which is easily broken down by static electricity, and the human body sometimes generates high-voltage static electricity of up to several volts or hundreds of volts, so it is operated and assembled. And be careful during use to prevent static electricity. to this end:


1. If direct contact is required, keep a module of the human body at the same potential or ground the human body well. The most important thing is not to touch the outer leads, the circuit board and the metal frame on your board.


2. Electric operation The tool such as the cone must be well grounded and there is no leakage. The main thing is that the soldering iron used in soldering must be well grounded and there is no leakage.


3, the ground, workbench, chairs, shelves, carts and tools should be formed with electrical resistance to maintain the same potential, otherwise static electricity will also be generated.


4. Do not use a vacuum cleaner for cleaning. Because it produces a strong static electricity. When taking it out or putting it back in the bag or moving it, be careful not to generate static electricity. Do not change or discard the original packaging at will.


5, the air is dry, it will also generate static electricity, therefore, the humidity in the workplace should be above RH60%.
