[Note 3] Lamp frequency of inverter may produce interference with horizontal
synchronous frequency,and this may cause horizontal beat(Waving) 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
[Note 4] FL: 50~60KHz for best optical and electrical performance
FL: 40~80KHz for life and reliability assurance
