【Note6】The performance of the backlight, for example life time or brightness, is much influenced
【Note7】It is required to have the inverter designed so that to allow the impedance deviation of the two CCFT
【Note8】Under the environment of 10 lx or less, miss-lighting delay may occur.
【Note9】A lamp waveform should satisfy the following conditions.
8. Timing characteristics of input signals

【Note】 In case of using the long vertical period, the deterioration of display quality, flicker etc. may occur.
by the characteristics of the DC-AC inverter for the lamp. When you design or order the inverter,
please make sure that a poor lighting caused by the mismatch of the backlight and the inverter
(miss-lighting, flicker, etc.) never occur. when you confirm it, the module should be operated in the
same condition as it is installed in your instrument.
Be sure to use a back light power supply with the safety protection circuit such as the detection circuit
for the excess voltage, excess current and or electric discharge waveform.
Be sure to use the detect circuit by which one side of the CCFT lamps can be controlled independently.
Otherwise, when one side of the CCFT is open, the excess current may possibly be applied to the other
side of the lamp.
