5.2 Backlight Unit
5.2.1 Parameter guideline for LED
Following characteristics are measured under stable condition using a LED driving board at 25
LED Forward Current
VF LED Forward Voltage
- 80 84 mA Ta = 25oC
- Volt IF = 80mA, Ta = -30oC
Volt IF = 80mA, Ta = 25oC
- Volt IF = 80mA, Ta = 85oC
Hrs IF = 80mA, Ta = 25oC
Note 1: Ta means ambient temperature of TFT-LCD module.
Note 2: If G150XG01 V2 module is driven by high current or at high ambient temperature & humidity condition. The
operating life will be reduced.
Note 3: Operating life means brightness goes down to 50% initial brightness. Typical operating life time is estimated
G150XG01 V2 rev 0.0
