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 (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

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 VS should be applied to the lamp for more than 1 second under starting

up duration. Otherwise the lamp could not be lighted on completed.

Note (3) The lamp frequency may produce interference with horizontal synchronous frequency from the

display, and this may cause 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.) as the time in which it continues to operate under the condition Ta = 25 2к and
