1) If the waveform of light up-driving 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 fulfill the conditions
under the inverter designing-stage as below:
2) The lamp working current (I

4) a. Frequency in this range can make the characteristics of electric and optics maintain in +/- 10%
except color coordinates.
b. Frequency in 50~60kHz can make characteristics of electric and optics better.
c. Frequency in 45~80kHz won’t damage the lifetime and reliability of lamp.
d. Lamp frequency of inverter may produce interference with horizontal(or vertical) synchronous
frequency,and this may cause horizontal beat on the display.Therefore, please adjust lamp
frequency, and keep inverter as far from module as possible or use electronic shielding
between inverter and module to avoid the interference.
5) Definition of the lamp life timeΚ
a. Luminance (L) under 50% of specification.
b. Starting Lamp Voltage: over130% of the initial value. Ta=25к
6) The condition of Turn-on and Turn-off operation is as below:
a. Lamp current is 7.5mA
b. Frequency is 10 sec.(on)/10 sec.(off)
c. Repeat it for 100 thousand times
d. The lamp hue variation must smaller than 0.03
e. It should not have motion fail when starting lamp voltage is lower than 130%of the initial
value.
7) For keeping good lighting situation, when design the inverter, it must be considered that the
voltage large than starting lamp voltage.
8) WL=IL x VL x 4Ζ(IL=7.5mAΔTa=25к)
9) The Starting Lamp Voltage (VS) of inverter must be driven large than one second.
10) The output voltage of inverter (Vn) must be the same phase of between any lamps.
11) The difference in voltage between any lamps ( V) must be smalleϦ r than 300V at the same time.
