Note (2) The voltage shown above should be applied to the lamp for more than 1 second after startup.
Otherwise the lamp may not be turned on normally. It is the value output voltage of NF circuit.
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

C and IL = 7.5 mA rms until one of the following events occurs:
(a) When the brightness becomes 50% of its original value.Љ
(b) When the effective ignition length becomes 80% of its original value.Љ
(The effective ignition length is a scope that luminance is over 80% of that 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
