*1 It is recommended that IL is no greater than 6 mArms so that the effect of heat radiation from CCFT
backlight on display quality is minimized
*2 Power consumption excluded inverter efficiency loss.
*3 The output voltage of the inverter should be set to Vs adding some margin as Vs of CCFT bulb may
be increased due to AC coupling leakage to the chassis of the LCD module.
*4 Average life time of CCFT bulb will be decreased when LCD is operated at lowtemperature.
