*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.
*3) Lamp life time is defined as the time either when the brightness becomes 50% of the initial value, or
when the starting lamp voltage does not meet the value specified in this table.
*4) The life time of the backlight depends on the ambient temperature. The life time will decrease under
low/high temperature.
