Note the use of A. LCD
1，Make sure that is in power down state plug cable.
2，On the LCD screen for fixed installation, pay attention to the LCD screen to keep smooth, avoid external cause LCD screen "bending", "twist". 3，Surface Polaroid 3 must be careful LCD screen, avoid the hard object (not scratch hard objects placed in the liquid crystal screen).
4，If the water a long time remain in the liquid crystal module, may cause discoloration or staining, so be sure to clean module.
5，When the screen surface stains, use cotton or soft cloth to wipe the dirt if or above, can blow and then wipe.
6，Should get / put the LCD module, because the liquid crystal box for glass products, is fragile, drop, beat may lead to broken glass.
7，LCD module uses CMOS-LSIs, so the processing of liquid crystal module, we must prevent the electrostatic, the operator must have effective grounding measures.
8，Plug the inverter, do not force pulling back light. 9，Don't be LCD module for long periods of time in direct sunlight or ultraviolet light.
10，Because the visual characteristics of liquid crystal module will change because of different perspectives. So in the assembly, should fully consider the user at the best angle position.
11 ，If the LCD is stored in the storage temperature is lower than the specified limit, the damage may be caused due to liquid crystal can not be restored. If the temperature in the environment exceeds the limit storage temperature, liquid crystal may become isotropic liquid which can not recover the liquid crystal.
12，Do not remove the LCD module, it may damage the LCD module.
13，Epoxy resin using 13 equipment or in packaging materials (amine hardener), silicon resin adhesive (alcohol binder or oxime adhesive) degradation from gas may cause polarizer. So it is necessary to check the use of material compatibility
14，In the back of the liquid crystal module of electronic components, so avoid extrusion at the back of the design, assembly, the disposal process, otherwise you may damage electronic components.
15，The other 15 to comply with the relevant electronic components of the matters needing attention, suggested as close as possible to the actual operation condition check the LCD module.
16，Because the LCD module is the outer packaging, so the design of small and medium heart attachment.
17，The 17 inserting interface connector, connector and liquid crystal module to maintain at the same level and parallel direction。
18，In the disposal of liquid crystal module or contained in equipment, if long time placed in oxidizing or reducing gas in the air, or the use of reagents, solvents, adhesives, resins and other produce this type gas material, may lead to corrosion, color LCD module
19，The module is placed in a high temperature environment 19 don't attach protective film protective film, otherwise it will stick to the surface of the module can't pull down
20，The 20 best at any time, do not touch LCD polarizers, stain easily leave blotch.
21，Any time (including time out of the package box) don't pull the backlight lamp wires, or easy to damage the wire.
22，Suggestions for disposal of liquid crystal module operators wear anti-static clothing, and wearing grounded wrist strap.
23，Of the rear of the module TCP, don't put too much pressure, otherwise it will damage the TCP.
The B. module processing considerations
Outer lead 1 LCD module must not be allowed to take the wrong, or it may cause overcurrent, overvoltage and cause damage to the module device.
The 2 module using the access to power and disconnect the power, must be in the positive supply (5 ± 0.25V) stable access, to the input signal level. As in a stable power supply before or after disconnecting the input signal level, there may be damage to IC circuit module.
The 3 solder iron temperature: 280 ± 10 ℃ welding time: <3-4S; welding material: eutectic type, low melting point; repeated welding shall not be more than 3 times.
4 press the display part, have unusual display, then disconnect the power, wait a moment, re power, returned to normal
The C. module storage note
If the long-term (such as a few years) storage, we recommend the following way:
1 into the polyethylene bag (the best antistatic coating) and the seal
In 2 place, avoid light
3 never put anything in the surface pressure
4 strictly avoid storage in over limit temperature, humidity environment
