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

| Input leakage current | IIL | -1.0 | - | 1.0 | mA | VIN=VDD or VSS |
Note: Voltage greater than above may damage the module.
All voltages are specified relative to VSS=0V.
2) Driving Backlight
