Characteristics
2.2
Backlight Unit
Following characteristics are measured under a stable condition at 25°C (Room Tem-
perature):
Note 1
Ta means ambient temperature of TFT-LCD module.
Note 2
VCC, Ivcc, PVCC, Irush LED are defined for LED B/L.(100% duty of PWM
dimming).
Note 3
IF, VF , PLED are defined for LED Light Bar.
Note 4
If IDK-1119R-35SXA1E module is driven by high current or at high ambient
temperature & humidity condition. The operating life will be reduced.
Note 5
Operating life means brightness goes down to 50% initial brightness. Mini-
mum operating lifetime is estimated data.
