Note 2: The waveform of lamp driving voltage should be as closed to a perfect sine wave as possible. Note 3: The Max. of starting voltage means the minimum voltage of inverter to turn on the CCFl and it should be applied to the lamp for more than 1 second to start up. Otherwise the lamp may not be turned on. Backlight Power Consumption Item Specifications Unit Typ. Max.
