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

Note (5) The power supply capacity should be higher than the total inverter power consumption P

L

. Since

BL

the pulse width modulation (PWM) mode was applied for backlight dimming, the driving current

changed as PWM duty on and off. The transient response of power supply should be considered

for the changing loading when inverter dimming.
