(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.

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 к at normal humidity without condensation.
(b) The module shall be stroed in dark place. Do not store the TFT-LCD module in direct sunlight or fluorescent
light.

Note (1) The power supply capacity should be higher than the total converter 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 converter dimming.
Note (2) The measurement condition of Max. value is based on 37" backlight unit under input voltage 24V,
average LED current 127.2 mA and lighting 1 hour later.
Note (3) The duration of Input Rush Current is about 30ms.
Note (4) 5% minimum duty ratio is only valid for electrical operation.
