(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 white.
(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.

7. GENERAL PRECAUTIONS
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 (Isoprophyl 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 C-MOS Gate Array IC.
(i) Use fingerstalls 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 back side.
(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.

-The storage room should provide good ventilation and temperature
control.
- Products should not be placed on the floor, but on the Pallet away
from a wall.
- Prevent products from direct sunlight, moisture nor water; Be
cautious of a build up of condensation.
- Avoid other hazardous environment while storing goods.
- If products delivered or kept in conditions of over the storage
period of 3 months, the recommended temperature or humidity
range.
we recommend you leave the at a temperature of 20 and a
humidity of 50% for 24 hours.

3. OPERATION
(a) Do not connect, disconnect the module in the Power On condition.
(b) Power supply should always be turned on/off by following 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.
(d) The standard limited warranty is only applicable when the module is used for general
notebook applications. If used for purposes other than as specified, SEC is not to be
held reliable for the defective operations. It is strongly recommended to contact SEC
to find out fitness for a particular purpose.

4. 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, 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.
(e) This module has its circuitry PCBs on the rear side and should be handled carefully in
order not to be stressed.
