(a) When the module is assembled, it should be attached to the system firmly
(e) If the surface of the polarizer is dirty, clean it using absorbent cotton or soft cloth
(g) If the liquid crystal material leaks from the panel
should be kept
away

8. General Precautions
PRODUCT INFORMATIONPRODUCT INFORMATION
8.1 Handling
using all mounting holes. Be careful not to twist and bend the module.
(b) Refrain from strong mechanical shock and / or any force to the module.
In addition to damage, it may cause improper operation or damage to the module
and LED back light.
(c) Note that polarizer films are very fragile and could be damaged easily.
Do not press or scratch the surface harder than a HB pencil lead.
(d) Wipe off water droplets or oil immediately. If you leave the droplets for a long
time, staining or discoloration may occur.
.
(f) Desirable cleaners are water, IPA (Isopropyl Alcohol) or Hexane.
Do not use Ketone type materials (ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid
or Methyl chloride. It might cause permanent damage to the polarizer due to chemical
reaction.
, it
from the eyes or mouth . In case of contact with hands, legs or clothes, it must
be washed away with soap thoroughly.
(h) Protect the Module from static, or the CMOS Gate Array IC would be damaged.
(i) Use finger-stalls with soft gloves in order to keep display clean during the
ncoming inspection and assembly process.
(j) Do not disassemble the Module.
(k) Protection film for polarizer on the Module should be slowly peeled off just before use
so that the electrostatic charge can be minimized.
(l) Pins of I/F connector should not be touched directly with bare hands.

PRODUCT INFORMATIONPRODUCT INFORMATION
8.2 Storage
(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
and relative humidity of less than 70%.
(b) Do not store the TFT-LCD Module in direct sunlight.
(c) The Module should be stored in a dark place. It is prohibited to apply sunlight or
fluorescent light in storing.
8.3 Operation
(a) Do not connect or disconnect the Module in the "Power On" condition.
(b) Power supply should always be turned on/off by the item 6.3
"Power on/off sequence"
(c) Module has high frequency circuits. Sufficient suppression to the electromagnetic
erence should be done by system manufacturers. Grounding and shie
methods may be important to minimize the interference.
(d) The cable between the back light connector and its converter power supply should
be connected directly with a minimized length. A longer cable between
the back light and the convertor may cause lower luminance of LED
8.4 Operation Condition Guide
(a) The LCD product should be operated under normal conditions.
Normal condition is defined as below;
- Temperature : 20·15
-
- Display pattern : continually changing pattern (Not stationary)
ng
(b) If the product will be used in extreme conditions such as high temperature,
humidity, display patterns or operation time etc.., It is strongly recommended
to contact SEC for Application engineering advice. Otherwise, its reliability and
function may not be guaranteed. Extreme conditions are commonly found at
Airports, Transit Stations, Banks, Stock market, and Controlling systems.

Otherwise the Module may be damaged.
(d) If the Module keeps displaying the same pattern for a long period of time,
the image may be “stuck" to the screen.

(e) This Module has its circuitry PCB's on the rear side and should be handled
carefully in order not to be stressed.
(f) Please contact SEC in advance when you display the same pattern for a long time.
