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.

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.

C and IL = 6.0 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
