Parameter guideline for CCFL Inverter
Note 1: Typ are AUO recommended Design Points.
Note 2: It should be employed the inverter which has “Duty Dimming”, if ICCFL is less than 4mA.
Note 3: CCFL discharge frequency should be carefully determined to avoid interference between inverter and
TFT LCD.

*2 In case of using an inverter other than listed, it is recommended to check the inverter carefully.
Sometimes, interfering noise stripes appear on the screen, and substandard luminance or flicker at low power
may happen.
*3 In designing an inverter, it is suggested to check safety circuit very carefully. Impedance of CCFL, for
instance, becomes more than 1 [M ohm] when CFL is damaged.
*4 Generally, CCFL has some amount of delay time after applying kick-off voltage. It is recommended to
keep on applying kick-off voltage for 1 [Sec] until discharge.
*5 CCFL discharge frequency must be carefully chosen so as not to produce interfering noise stripes on the
screen.
*6 Reducing CCFL current increases CCFL discharge voltage and generally increases CCFL discharge
frequency. So all the parameters of an inverter should be carefully designed so as not to produce too much
leakage current from high-voltage output of the inverter.
