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
