[Note 2]

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.

The degrees of unbalance: less than 10%

The ratio of wave height: less than √2 ±10%

The degrees of umbalance = Ip-I-p /Irms*100(%)
