4.2 Backlight Unit Item Symbol Forward Current IF Forward Voltage VF Backlight Power Consumption WBL LED lifetime Note1: Remark 1 LED 1 LED 6 LEDs in parallel Figure below shows the connection of backlight LED. Note 2: 1LED: VF =3.2V I =20mA F Note 3: : IF is defined for one LED. Optical performance should be evaluated at Ta=25℃ only. If LED is driven by high current, high ambient temperature & humidity condition. The life time of LED will be reduced. Operating life means brightness goes down to 50% initial brightness. Typical operating life time is estimated data. 4.3 Block Diagram The information...
