Back-Light Unit Characeristics
The back-light system is an edge-lighting type with 18 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 | -- | 60 | -- | mA | -- |
| Luminance(With LCD) | Lv | -- | 1000 | -- | 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.
Optical Specification
Note (1)Definition of Contrast Ratio (CR):
The contrast ratio can be calculated by the following
expressionContrast Ratio (CR)=L255/L0
L255: Luminance of gray level 255
L 0: Luminance of gray level 0
CR= CR (5)
CR (X) is corresponding to the Contrast Ratio of the point X at
Figure in Note (5)
