5. 2 ELECTRICAL CHARACTERISTICS OF BACKLIGHT
ITEM
(Note 1) Please design your lamp driving circuit (inverter) according to the above specifications,
and inform Hitachi of it.
(Note 2) Starting discharge voltage is increased w hen LCM is operating at lower temperature.
Please check the characteristics of your inverter before applying to your set.
(Note 3) Average life time of CFL w ill be decreased w hen LCM is operating at lower temperature.
(Note 4) Under low er driving frequency of an inverter, a certain backlight system (CFL & CFL
reflection sheet) may generate a sound noise. Before designing the inverter, please
consider the driving frequency and the noise.
(Note 5) Under low er temperature, please check CFL characteristics on your inverter.
