Note (1) Temperature and relative humidity range is shown in the figure below.
(a) 90 %RH Max. (Ta Љ 40 ºC).
(b) Wet-bulb temperature should be 39 ºC Max. (Ta > 40 ºC).
(c) No condensation.
Note (2) The maximum operating temperature is based on the test condition that the surface temperature of
display area is less than or equal to 65 ºC with LCD module alone in a temperature controlled chamber.
Thermal management should be considered in your 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 your product design.
Note (3) 11 ms, half sine wave, 1 time for ± X, ± Y, and ± Z.
Note (4) 10 ~ 200 Hz, 10 min, 1 time each X, Y, Z.
Note (5) At testing Vibration and Shock, the fixture in holding the module has to be hard and rigid enough so that
the module would not be twisted or bent by the fixture. The module would not be twisted or bent by the
fixture.

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 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 IL = 9.7~ 10.7mArms.
Note (5) The power supply capacity should be higher than the total inverter power consumption PBL. Since
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 46" backlight unit under input voltage 24V,
average lamp current 10.5 mA and lighting 30 minutes later.
