Lamp life time *1)
[Note]
*1) The time that module luminance reduced to 50% of initial value, Base on Ta=25℃, I
*2)“Life time” is defined as the lamp brightness decrease to 50% original brightness at I
*3) For starting the backlight unit,the output voltage of DC/AC’s transformer should be larger than the
*4) If the driving waveform of Lamp is asymmetric, the distribution of mercury inside the lamp tube will
become unequally or will deplete the Ar gas in it. Then it may cause the abnormal phenomenon of lighting-
up. Therefore, designers have to try their best to for fill the conditions under the inverter designing-stage
