Note 1) Test Equipment Setup
After stabilizing and leaving the panel alone at a given temperature for 30 min ,the
measurement should be executed. Measurement should be executed in a stable, windless, and
dark room. 30 min after lighting the back-light. This should be measured in the center of
screen.
A single lamp current : 5.0mA
Environment condition : Ta = 25 ± 2 ° C

NOTE.
(1)The supply voltage of the external system for the module input should be the
same as the definition of VDD.
(2) Apply the lamp voltage within the LCD operation range. When the back-light turns
on before the LCD operation or the LCD turns off before the back-light turns off,
the display may momentarily become abnormal screen.
(3) In case of VDD = off level, please keep the level of input signals on the low or
keep a high impedance.
(4) T4 should be measured after the module has been fully discharged between
power off and on period.
(5) Interface signal shall not be kept at high impedance when the power is on.

10. General Precautions
Product Information
10.1 Handling
(a) When the module is assembled, It should be attached to the system firmly
using every mounting holes. Be careful not to twist and bend the modules.
(b) Refrain from strong mechanical shock and / or any force to the module. In
addition to damage, this may cause improper operation or damage to the module
and CCFT back-light.
(c) Note that polarizers are very fragile and could be easily damaged. 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 and discoloration may occur.
(e) If the surface of the polarizer is dirty, clean it using some absorbent cotton or
soft cloth.
(f) The 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 permanent damage to the polarizer due to
chemical reaction.
(g) If the liquid crystal material leaks from the panel, it should be kept away
from the eyes or mouth . In case of contact with hands, legs or clothes, it must
be washed away thoroughly with soap.
(h) Protect the module from static , it may cause damage to the CMOS Gate Array IC.
(i) Use finger-stalls with soft gloves in order to keep display clean during the
incoming inspection and assembly process.
(j) Do not disassemble the module.
(k) Do not pull or fold the lamp wire.
(l) Do not adjust the variable resistor which is located on the module.
(m) Protection film for polarizer on the module shall be slowly peeled off just before use
so that the electrostatic charge can be minimized.
(n) Pins of I/F connector shall not be touched directly with bare hands.

10.2 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 35C
and relative humidity of less than 70%.
(b) Do not store the TFT-LCD module in direct sunlight.
(c) The module shall be stored in a dark place. It is prohibited to apply sunlight or
fluorescent light during the store.
10.3 Operation
(a) Do not connect,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 interference shall be done by system manufacturers. Grounding
and shielding methods may be important to minimize the interference.
Product Information
(d) The cable between the back-light connector and its inverter power supply shall
be a minimized length and be connected directly . The longer cable between
the back-light and the inverter may cause lower luminance of lamp(CCFT) and
may require higher startup voltage(Vs).
10.4 Operation Condition Guide
(a) LCD product supposed to be operated under circumstance of normal condition.
Normal condition
- Temperature : 20
- Humidity : 65·20%
- Display pattern : continually changing pattern (Not stationary)
(b) When the product is used for special application where operates LCD products in a
special condition - sever then normal temperature or humidity or operation time or
display pattern -that may happen at Airport, Transit Station, Stock market, Bank, and
Controlling system Etc, please contact SEC and take application AMLCD engineers
advice. Otherwise, it may not be guaranteed its life time and function.

10.5 Others
(a) Ultra-violet ray filter is necessary for outdoor operation.
(b) Avoid condensation of water. It may result in improper operation or disconnection
of electrode.
(c) Do not exceed the absolute maximum rating value. ( the supply voltage variation,
input voltage variation, variation in part contents and environmental temperature,
and so on) Otherwise the module may be damaged.
(d) If the module displays the same pattern continuously for a long period of time,it
can be the situation when the image "Sticks" to the screen.
We recommend that you should discuss SEC when you want the module to be

Product Information
operated in displaying the same pattern for a long time.
(e) This module has its circuitry PCB's on the rear side and should be handled
carefully in order not to be stressed.
