Note (2) The voltage that must be larger than Vs 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 synchronization frequency from the
display, which might cause line flow on the display. In order to avoid interference, the lamp
frequency should be detached from the horizontal synchronization frequency and its harmonics as
far as possible.
Note (4) PL = IL ͪ VL ͪ 2 (for 2 lamps)
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 Љ 50% of its original value.
(b) When the effective ignition length becomes Љ 80% of its original value.
(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 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.(Unsymmetrical ratio is less than 10%) Please do not use the inverter
which has unsymmetrical voltage and unsymmetrical 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
