10.In case of edgy type back light with over 4 parallel lamps, input current and voltage
9. The inverter which is combined with this LCM, is highly recommended to connect

8. The output of the inverter must have symmetrical(negative and positive) voltage
* Inverter output waveform had better be more similar to ideal sine wave.
waveform and symmetrical current waveform (Unsymmetrical ratio is less than 10%).
Please do not use the inverter which has unsymmetrical voltage and unsymmetrical
current and spike wave. Requirements for a system inverter design, which is intended to
have a better display performance, a better power efficiency and a more reliable lamp,
are following.It shall help increase the lamp lifetime and reduce leakage current.
coupling(ballast) condenser at the high voltage output side. When you use the inverter
which has not coupling(ballast) condenser, it may cause abnormal lamp lighting because
of biased mercury as time goes.
a. The asymmetry rate of the inverter waveform should be less than 10%.
b. The distortion rate of the waveform should be within √2 ±10%.
