12. Backlight Characteristic Measurement Conditions
13. Backlight Uniformity Measurement Method
14. Backlight Life Measurement Method
15. Backlight Dark Lighting Characteristics Measurement Method
1) Test inverter operating conditions (using a Stanley 13585A inverter)
2) Ambient temperature and humidity
3) Luminance and chromaticity measurement
Start each measurement 10 minutes after the backlight is lit.
Luminance uniformity of the backlight is obtained by measuring the luminance at the 9 points shown below
and calculating Min. luminance ÷ Max. luminance
Definition or life: When the center luminance drops to 50% of the initial value during continuous lighting, or
when normal lighting becomes impossible.
Lighting conditions: 25 ± 5°C, CCFL current: 2.4mArms
Shelf conditions: Leave for 70 hours or more in the dark at each temperature (25°C, –10°C) condition.
Lighting conditions: 0.5 lx or less at each temperature (25°C, –10°C) condition.
Lighting time: Time from power-on until the backlight is lit.
Driving frequency: 58.4kHz
Input voltage: 6.1V
Input current: 0.105mA
Input power: 0.64W
Tube current: 2.4mA
Tube voltage: 200V
Tube power: 0.48W
Temperature: 25 ± 1°C
Humidity: 30 to 85%
(Start measurement after leaving the module in the above environment for one hour.)
Measurement should be performed in a dark room with a luminance of 10 lx or less and which is not
subject to the effects of reflective or external light.
There should be no heat insulating objects around the module unit, and measurement should be
performed in a draftless condition.
Measurement equipment: TOPCON BM-5A, viewing angle: 0.1°, distance: 500mm
Measure 10 minutes after the backlight is lit.
