Preliminary
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. Lamp frequency may
produce interface with horizontal synchronous frequency and as a result this may cause beat on the
display. Therefore lamp frequency shall be as away possible from the horizontal synchronous
frequency and from its harmonics in order to prevent interference.
Requirements for a system inverter design, which is intended to have a better display performance, a
better power efficiency and a more reliable lamp. It shall help increase the lamp lifetime and reduce its
leakage current.
a. The asymmetry rate of the inverter waveform should be 10% below;
b. The distortion rate of the waveform should be within √2 ± 10%;
c. The ideal sine wave form shall be symmetric in positive and negative polarities.
* Asymmetry rate:
Ip
| I p – I –p | / Irms * 100%
I -p
* Distortion rate
I p (or I –p) / Irms
10 / 25
