Precautions For Use of LCD Modules
1 Handling Precautions
If the display surface is contaminated, breathe on the surface and
gently wipe it with a soft dry cloth. If still not completely
clear, moisten cloth with one of the following solvents:
－Isopropyl alcohol
－Ethyl alcohol
Solvents other than those mentioned above may damage the polarizer.
Especially, do not use the following:
－Water
－Ketone
－Aromatic solvents
2 Transportation Precautions
The LCD modules should be no falling and violent shocking during
transportation, and also should avoid excessive press, water, damp
and sunshine.

Absolute Maximum Ratings
| Item | Symbol | Value | Unit |
| Power supply voltage for logic | VDD | 0.3~4.8 | V |
| Input voltage | Vin | VDD+0.3 | V |
| Operating temperature | Topr | -20 to 70 | °C |
| Storage temperature | Tstg | -30 to 80 | °C |
Note:
Note1: Absolute maximum rating is the limit value beyond which the
IC maybe broken.
They do not assure operations.
Note2: Background color changes slightly depending on ambient
temperature.
This Phenomenon is reversible.
Ta≦70℃: 75%RH max
Ta>70℃: absolute humidity must be lower than the humidity of
75%RH at 70℃
Note3: Ta at -30℃ will be <48hrs, at 80 ℃ will be <120hrs
