Back-Light Unit Characeristics
The back-light system is an edge-lighting type with 4 white LEDs. The characteristics of the back-light are shown in the following tables.
| Characteristics | Symbol | Min. | Type | Max. | Unit | Notes |
| Forward Voltage | VF | 2.8 | -- | 3.2 | V | -- |
| Forward current | IF | -- | 80 | -- | mA | -- |
| Luminance(With LCD) | Lv | -- | 450 | -- | cd/m2 | -- |
| LED life time | N/A | -- | 30,000 | -- | Hr | Note 1 |
Note:
(1)The “LED life time” is defined as the module brightness decrease to 50% of original brightness at IL=20mA/LED. The LED life time could be decreased if operating IL is larger than 25mA/LED.
