Model No.: V270W - L03
Approval
Otherwise the lamp may not be turned on.
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.

= (4.35) ~ (4.95) mArms until one of the following events occurs:
(a) When the brightness becomes equal or less than 50% of its original value.
(b) When the effective discharge length becomes equal or less than 80% of its original value.
(Effective discharge length is defined as an area that has equal or more than 70% brightness
compared to the brightness at 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.
