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
