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≦60℃: 75%RH max
Ta>60℃: absolute humidity must be lower than the humidity of 75%RH at 60℃
Note3: Ta at -20℃ will be <48hrs, at70 ℃ will be <120hrs

7-2 Backlight Electrical-optical Characteristics
1. Stander Lamp Styles (Edge Lighting Type):
The LED chips are distributed over the edge light area of the illumination unit, which gives the
less power consumption:
2. The Main Advantages of the LED Backlight are as following:
2.1 The brightness of the backlight can simply be adjusted by a resistor or a potentiometer.
