2: Recommended value of “F0.”
3: The asymmetric ratio of working waveform for lamps (Power supply voltage peak ratio, power supply
• F0 is within the specification.
• F0 = ¼ th × (2n − 1)
If F0 is out of the recommended value, interference between F0 frequency and Hsync frequency may
cause beat on the display.
current peak ratio and waveform space ratio) should be less than 5 % (See the following figure.). If
the waveform is asymmetric, DC (Direct current) element apply into the lamp. In this case, a lamp
lifetime may be shortened, because a distribution of a lamp enclosure substance inclines toward one
side between low voltage terminal (Cold terminal) and high voltage terminal (Hot terminal).
