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	V_F	16.8	--	19.2	V	--

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 I_L=20mA/LED. The LED life time could be decreased if operating I_L 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)
