4.0
4.1 Signal for Lamp connector
4.2 Parameter guide line for CFL Inverter
Note 1: Duration=50 [msec]
Note 2: CCFL Frequency should be carefully determined to avoid interference between inverter and TFT LCD
Note 3: Calculator value for reference (ICFL×VCFL=PCFL)
Note 4: CCFL inverter should be able to give out a power that has a generating capacity of over 1700 voltage.
Lamp units need 1700 voltage minimum for ignition
