A. LCD matters need attention
1. Ensure that is in the power of the state in closed out cable

2. The LCD screen of fixed installation, pay attention to make whole LCD screen saver the level off, avoid external forces lead to LCD screen "bending," "distorted"
  

  3. Be careful of liquid crystal screen surface of polarizing, avoid being hard object scratches (never put hard goods in LCD screen above)
4. If water droplets long time stuck in LCD module, may lead to change color or appeared blotch, so be sure to clean module

  5. When the screen surface is smear, must use pure cotton or soft cloth to wipe if still have dirt on it, and can blow first and then to wipe

  6. Should take/put LCD module, because LCD box as glass products, is a fragile, drop, beating could lead to broken
7. LCD module used the CMOS-LSIs, so deal with LCD module, be sure to prevent electrostatic, the operator shall be effective grounding measures
 

8. Pull plug inverter, don't force ye pull backlighting line

9. Don't will LCD module too long time in the sun or the ultraviolet ray

10. Because LCD module visual characteristics will be different because of the Angle of change. So in the assembly, should be fully considered the best Angle in the position of the users.

11. If LCD stored in storage temperature under the lower provisions below, may cause crystallization can lead to restore and liquid crystal of damage. If placed in storage temperature more than the temperature of the upper limit environment, liquid crystal can become isotropic liquid and no recovery liquid crystal state.

12. Do not remove LCD module, which is very possible damage to the LCD module
13. Equipment or packaging materials used in the epoxy resin (amine sclerosis content), silicon resin adhesives (take off alcohol adhesive or latter adhesives) from a gas may cause the PianZhenPian degradation. It is necessary to check the use of material compatibility
14. In the back of the LCD module have electronic components, so in design, assembly, and the disposal process to compress the back, or you could damage the electronic components
15. Abide by relevant electronic components of other matters need attention, the proposal as far as possible in close to the real operating environment conditions check LCD module

16. Because LCD module is outside the box package, so be careful to use in the design of the attachment

17. Plug-and-socket interface connectors to keep and LCD module of connectors at the same level and parallel direction
18. In the disposal LCD module or installed in equipment, if long placed in oxidation reduction in the air or gas, or use of the reagents, solvent, adhesives, resin will produce this kind of gas material, can lead to LCD module corrosion, become can not put it off.

19. Don't adhere to the high temperature environment protective film module, or protective film sticks to the module off the surface not come down

20. The best at any time, don't touch the LCD module of the polarization, get dirty leave blotch .

21. Any time (including take out from the packing of the time) don't slam drag a backlight wire, otherwise easy to damage the wires .
22. Suggest the operator disposal when LCD module wearing anti-static uniform, and wear the grounding bracelets

23. On the back of the module of the TCP, don't put any pressure, can damage otherwise TCP

B. Module processing the matters needing attention
1. The LCD module should never be allowed to pick the wrong lead, otherwise may cause the flow, over-voltage, etc and the module components produce damage.
2. Use access power and module off the power, must be in positive supply (5 + /-0.25 V) stable access later, can input signal level. As in stable power supply before or after disconnect input signal level, may damage the IC module circuit.
3. Solder iron temperature: 280 + 10 ℃ welding time: < 3-4 S; Welding materials: eutectic type, low melting point; Repeat welding shall not be more than three times.
4. You push hard on the show place, can produce abnormal display, then disconnect the power supply, wait a moment for a while, to electricity, the is back to normal
C. Module storage precautions
If long-term (such as a few years) store, we recommend the following ways:
1. Into polyethylene bag (had better have antistatic coating) and sealing mouth
2. Put the dark place, avoid strong light
3. Never put anything in surface pressure
4. Strictly avoid in more than limit temperature, humidity conditions for the environment
