*1) Table of specifications are definition of single lamp.
*2) 1.Frequency in this range , the characterisitics of electric and optics can maintain in ±10% except hues.
*3)1.Starting Lamp Voltage: Vs = initial value Vs
*4) Definition of the lamp life time：Luminance(L) under 50% of specification starting lamp voltage.
*5) Test condition of Turn on and off life : Turn on and off lamp at IL=6.0mA and (Ta=25 ±
frequency is 30 sec.(on )on/ 30 sec. (off ) and go on 100,000 times repeatedly.
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 as below:
vertical synchronous frequency),and this may cause ripple noise on the display. Therefore, please adjust
inverter frequency, and keep inverter as far from module as possible or use electronic shielding between
inverter and module to avoid the interference.

2.Lamp frequency of inverter may produce interference with horizontal synchronous frequency (or
starting voltage greater then max. voltage of starting lamp to certify starting lamp stability.
2.Definition of starting lamp voltage means max. voltage of starting lamp. We suggest the inverter
