Corrosive Gas Not Acceptable Not Acceptable
CFL Life Time 50,000 h
(Average) (Note 11) - at 25℃ , IL=4.0mA max.
Note 1 : Ta≦40℃ : 85%RH max.
Ta>40℃ : Absolute humidity must be lower than the humidity of 85%RH at 40℃.
Note 2 : For storage condition Ta at -30℃ < 48h , at 80℃ < 100h.
For operating condition Ta at -20℃ < 100h
Note 3 : Background color changes slightly depending on ambient temperature.
This phenomenon is reversible.
Note 4 : 5Hz~100Hz(Except resonance frequency)
Note 5 : This LCM will resume normal operation after finishing the test.
Note 6 : The response time will be slower at low temperature.
Note 7 : Only operation is guarantied at operating temperature. Contrast, response time,
another display quality are evaluated at +25℃.
Note 8 : When LCM is operated over 60℃ ambient temperature , the ICFL of LCM should
be adjusted to 3mA max.
Note 9 : Pulse Width : 10ms
Note 10 : This is panel surface temperature , not ambient temperature.
Note 11 : When brightness reached 50% of initial brightness.
Note 12 : When LCM be operated less than 0℃ , the life time of CFL will be reduced .
The rise time of CFL ON will be longer when the ambient temperature below 0℃
and confirming the characteristics of inverter is necessary .
