and slave board.
Note (2) The lamp starting voltage V
should be applied to the lamp for more than 1 second after startup.
S
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 its 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 of lamp.) as the time in which it continues to operate under the condition at Ta = 25 2к
