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 forfill the conditions
under the inverter designing-stage as below:

2) a.Frequency in this range can mala the characterisitics of electric and optics maintain in +/- 10%
except hue.

b.If the lamp frequency can be maintain in 50~60KHz, the better charactristics of the electrical

and the optical can be presented.

c.If the operating frequency is 40~80 KHz, the life time and the reliability of the lamp will not

be affect.

d.Lamp frequency of inverter may produce interference with horizontal 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.

3) Definition of the lamp life timeΚ Luminance (L) under 50% of specification starting lamp

voltage or starting lamp voltage is more than 130% of the initial value

4) The condition of Turn-on and Turn-off operation is as below:

a. Lamp current is 8.0mA
b. Frequency is 10 sec.(on)/10 sec.(off)
c. Repeat it for 10 thousand times
d. The result of eye-atching of the lamp hue is normal, and can switch the lamp.

It should not have motion fail when starting lamp voltage is lower than 130% of the initial value

5) It is necessary to consider the maximal value when design inverterΔin order to asure lighting.
