Thermal management should be considered in final product design to prevent the surface temperature of
display area from being over 65 ºC. The range of operating temperature may degrade in case of improper
thermal management in final product design.

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 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 and I
Note (5) The power supply capacity should be higher than the total inverter power consumption P
= 7.1~ 8.1mArms.
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.
Note (6) The measurement condition of Max. value is based on 26" backlight unit under input voltage 24V,
average lamp current 7.9 mA and lighting 30 minutes later.
Note (7) 10% minimum duty ratio is only valid for electrical operation

Note (1) The Dimming signal should be valid before backlight turns on by BLON signal. It is inhibited to
change the internal/external PWM signal during backlight turn on period.
Note (2) The power sequence and control signal timing are shown in the following figure. For a certain
reason, the inverter has a possibility to be damaged with wrong power sequence and control
signal timing.
