8. The output of the inverter must have symmetrical(negative and positive) voltage 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.

a. The asymmetry rate of the inverter waveform should be less than 10%.

b. The distortion rate of the waveform should be within v2 ±10%.

* Inverter output waveform had better be more similar to ideal sine wave.

Ip

I -p

* Asymmetry rate:

| I p – I –p | / Irms x 100%

* Distortion rate

I p (or I –p) / Irms

9. The inverter which is combined with this LCM, is highly recommended to connect 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.

10.In case of edgy type back light with over 4 parallel lamps, input current and voltage wave form should

be synchronized
