Note 2 The voltage that must be larger than Vs should be applied to the lamp for more than 1 second
1
after startup. Otherwise, the lamp may not be turned on normally.
Note 3 The lamp frequency may produce interference with horizontal synchronous frequency from the
display, and this may cause line flow on the display. In order to avoid interference, the lamp
frequency should be detached from the horizontal synchronous frequency and its harmonics as far
as possible.

Note 5 The lifetime of lamp can be defined as the time in which it continues to operate under the condition
Ta = 25 2 oC and IL = 7.0 mArms until one of the following events occurs:
a When the brightness becomes or lower than 50% of its original value.
b When the effective ignition length becomes or lower than 80% of its original value. Effective
ignition length is defined as an area that has less than 70% brightness compared to the
brightness in the center point.
Note 6 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.

The output of the inverter must have symmetrical negative and positive voltage waveform and
symmetrical current waveform. Asymmetrical ratio is less than 10% Please do not use the inverter
which has asymmetrical voltage and asymmetrical current and spike wave. Lamp frequency may
produce interface with horizontal synchronous frequency and as a result this may cause beat on the
display. Therefore lamp frequency shall be as away possible from the horizontal synchronous
frequency and from its harmonics in order to prevent interference.
Requirements for a system inverter design, which is intended to have a better display performance, a
better power efficiency and a more reliable lamp. It shall help increase the lamp lifetime and reduce its
leakage current.
a. The asymmetry rate of the inverter waveform should be 10% below;
b. The distortion rate of the waveform should be within 2 ± 10%;
c. The ideal sine wave form shall be symmetric in positive and negative polarities.
* Asymmetry rate:

| I p – I –p | / I
