(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 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.

Unit Note

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 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

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 itó 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 =4.5~

5.5mArms.
