2.2 Package storage
When storing modules as spares for a long time, the following precaution is necessary.
(a) Do not leave the module in high temperature, and high humidity for a long time. It is highly recommended to
store the module with temperature from 0 to 35кat normal humidity without condensation.
(b) The module shall be stored in dark place. Do not store the TFT-LCD module in direct sunlight or fluorescent
light.

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 (6) The measurement condition of Max. value is based on 42" backlight unit under input voltage 24V,
average lamp current 6.1 mA and lighting 30 minutes later.
Note (7) The power consumption refers to the condition that Dynamic CR has been turned on.

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.
Note (3) The power sequence and control signal timing must follow the figure below. For a certain reason,
the inverter has a possibility to be damaged with wrong power sequence and control signal
timing.
