(a) When the module is assembled,It should be attached to the system firmly

il lead

with soap.

(j) Do not disassemble the module

thatth

9. GENERAL PRECAUTIONS

1. Handling

using selected 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 backlight.

(c) Note that polarizers are very fragile and could be easily damaged. Do not press or scratch

the surfaceharder than a HB penc

(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.

.

Approval

(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

(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.

.

(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

e electrostatic charge can be minimized.

(n) Pins of I/F connector shall not be touched directly with bare hands.

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 35qC and

.

(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.

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.

Approval

(d) The cable between the backlight connector and its inverter power supply shall be a

minimized len
and the inverter may cause lower luminance of lamp(CCFT) and may require higher
startup voltage(Vs).

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 PCB’s on the rear side and should be handled carefully in

order not to be stressed.
