Note (1) Temperature and relative humidity range is shown in the figure below.
(a) 90 %RH Max. (Ta 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 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 (3) 11 ms, half sine wave, 1 time for ± X, ± Y, ± 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.

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 35 at 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.

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 ±2 and IL = (8.5~ 11.0) mArms. 
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 42" backlight unit under input voltage 24V, average lamp current 9.3 mA and 10.8 mA and lighting 30 minutes later.

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.
Note (3) While system is turned ON or OFF, the power sequences must follow as below descriptions: Turn ON sequence: VBL → PWM signal → BLON
Turn OFF sequence: BLOFF → PWM signal → VBL
