Back-Light Unit Characeristics
The back-light system is an edge-lighting type with 6 white LEDs. The characteristics of the back-light are shown in the following tables.
| Characteristics | Symbol | Min. | Type | Max. | Unit | Notes |
| Forward Voltage | VF | 16.8 | -- | 19.2 | V | - |
| Forward current | IF | -- | 20 | - | mA | - |
| Luminance(With LCD) | Lv | | 1500 | -- | cd/m2 | - |
| LED life time | N/A | ---- | 30,000 | -- | Hr | Note 1 |
Note:
- 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.
