Notes 1) Temperature and Humidity should be applied to the LCD surface of a TFT module,

not to the system installed with a module.
Function of module is guaranteed in above operating temperature range,
but optical characteristics is specified for only 25°C operating condition.
The brightness of a CCFL tends to drop at low temperature. Besides, the life-time becomes
shorter at low temperature.

2) Ta d 40°C ……… Relative humidity should be less than 85%RH max. Dew is prohibited.
Ta > 40°C ……… Relative humidity should be lower than the moisture of the 85%RH at 40°C.

3) Frequency of the vibration is between 15Hz and 50Hz. (Remove the resonance point)

4) Pulse width of the shock is 3 ms.

2. OPTICAL CHARACTERISTICS

The following optical characteristics are measured when the LCD is set alone (apart from driving
circuits and monitor cabinets) and under stable conditions. It takes about 30 minutes to reach stable
conditions. The measuring point is the center of display area otherwise noted.
The optical characteristics should be measured in a dark room or equivalent state.

Measuring equipment: KONICA MINOLTA:CS-1000, or equivalent.

6) Distribution difference of CCFLs surface temperature should be less than 5°C.

7) When the lighting wave form of the inverter is asymmetry, the inclination of mercury is
generated. Therefore, please adjust the imbalance factor (|IP-I-P|/Irms×100) of the lighting
current wave form to 10% or less, and adjust the crest factor (IP (or I-P)/Irms) to 1.2~1.6.

8) The lighting wave form of the inverter is in-phase in a lamp unit.
