Note (1) Lamp current is measured by utilizing AC current probe and its value is average by measuring master
and slave board.
Note (2) The lamp starting voltage VS should be applied to the lamp for more than 1 second after startup.
Otherwise the lamp may not be turned on.
Note (3) The lamp frequency may produce interference with horizontal synchronous frequency of the display input
signals, and it may result in line flow on the display. In order to avoid interference, the lamp frequency
should be detached from the horizontal synchronous frequency and itó harmonics as far as possible.
Note (4) The life time of a lamp is defined as when the brightness is larger than 50% of its original value and the
effective discharge length is longer than 80% of its original length (Effective discharge length is defined
as an area that has equal to or more than 70% brightness compared to the brightness at the center point
