Note: The waveform of the voltage output of inverter must be area-symmetric and the design of the
inverter must have specifications for the modularized lamp. The performance of the Backlight,
such as lifetime or brightness, is greatly influenced by the characteristics of the DC-AC inverter
for the lamp. All the parameters of an inverter should be carefully designed to avoid producing too
much current leakage from high voltage output of the inverter. When designing or ordering the
inverter please make sure that a poor lighting caused by the mismatch of the Backlight and the
inverter (miss-lighting, flicker, etc.) never occurs. If the above situation is confirmed, the module
should be operated in the same manners when it is installed in your instrument.
