Packing Order

26. 12. HANDLING & CAUTIONS 12.1 Mounting Method
The panel of the LCD consists of two thin glasses with polarizers which easily get
damaged. So extreme care should be taken when handling the LCD.
 Excessive stress or pressure on the glass of the LCD should be avoided. Care must be
taken to insure that no torsional or compressive forces are applied to the LCD unit
when it is mounted.
 If the customer's set presses the main parts of the LCD, the LCD may show the abnormal
display. But this phenomenon does not mean the malfunction of the LCD and should be
pressed by the way of mutual agreement.
 To determine the optimum mounting angle, refer to the viewing angle range in the
specification for each model.
 Mount a LCD module with the specified mounting parts.
12.2 Caution of LCD Handling and Cleaning
 Since the LCD is made of glass, do not apply strong mechanical impact or static load
onto it. Handling with care since shock, vibration,and careless handling may seriously
affect the product. If it falls from a high place or receives a strong shock, the glass may
be broken.
 The polarizers on the surface of panel are made from organic substances. Be very
careful for chemicals not to touch the polarizers or it leads the polarizers to be deteriorated.
 If the use of a chemical is unavoidable, use soft cloth with solvent（recommended below）
to clean the LCD‘s surface with wipe lightly.
-IPA(Isopropyl Alcohol), Ethyl Alcohol, Trichlorotriflorothane
 Do not wipe the LCD's surface with dry or hard materials that will damage the polarizers
and others. Do not use the following solvent.
-Water, Ketone, Aromatics
It is recommended that the LCD be handled with soft gloves during assembly, etc. The
polarizers on the LCD's surface are vulnerable to scratch and thus to be damaged by
sharp particles.
 Do not drop water or any chemicals onto the LCD's surface.
 A protective film is supplied on the LCD and should be left in place until the LCD is
required for operation.
 The ITO pad area needs special careful caution because it could be easily corroded.
Do not contact the ITO pad area with HCFC, Soldering flux, Chlorine, Sulfur, saliva or
fingerprint. To prevent the ITO corrosion, customers are recommended that the ITO
area would be covered by UV or silicon. 26

27. 12.3 Caution Against Static Charge
 The LCD modules use C-MOS LSI drivers, so customers are recommended that
any unused input terminal would be connected to Vdd or Vss, do not input any signals
before power is turn on, and ground you body, work/assembly area, assembly
equipments to protect against static electricity.
 Remove the protective film slowly, keeping the removing direction approximate
30-degree not vertical from panel surface, If possible, under ESD control device like
ion blower, and the humidity of working room should be kept over 50%RH to reduce the
risk of static charge.
 Avoid the use work clothing made of synthetic fibers. We recommend cotton clothing or
other conductivity-treated fibers.
 In handling the LCD, wear non-charged material gloves. And the conducting wrist to the
earth and the conducting shoes to the earth are necessary.
12.4 Caution For operation
 It is indispensable to drive the LCD within the specified voltage limit since the higher
Voltage than the limit causes the shorter LCD's life. An electro-chemical reaction due to
DC causes undesirable deterioration of the LCD so that the use of DC drive should avoid.
 Do not connect or disconnect the LCD to or from the system when power is on.
 Never use the LCD under abnormal conditions of high temperature and high humidity.
 When expose to drastic fluctuation of temperature (hot to cold or cold to hot）,the
LCD may be affected; Specifically, drastic temperature fluctuation from cold to hot,
produces dew on the LCD's surface which may affect the operation of the polarizer
and the LCD.
 Response time will be extremely delayed at lower temperature than the operating
temperature range and on the other hand at higher temperature LCD may turn black at
temperature above its operational range. However those phenomena do not mean
malfunction or out of order with the LCD. The LCD will revert to normal operation once
the temperature returns to the recommended temperature range for normal operation.
 Do not display the fixed pattern for a long time because it may develop image sticking
due to the LCD structure. If the screen is displayed with fixed pattern, use a screen saver.
Do not disassemble and/or re-assemble LCM Module. 27

28. 12.5 Packaging 12.6 Storage 12.7 Safety
 Modules use LCD element, and must be treated as such.
-Avoid intense shock and falls from a height.
-To prevent modules from degradation, do not operate or store them exposed directly
to sunshine or high temperature/humidity for long periods.
12.6 Storage
 A slight dew depositing on terminals is a cause for electro-chemical reaction resulting
in terminal open circuit. Relative humidity of the environment should therefore be kept
below 60%RH.
 Original protective film should be used on LCD’s surface (polarizer). Adhesive type
protective film should be avoided, because it may change color and/or properties of
the polarizers.
 Do not store the LCD near organic solvents or corrosive gasses.
 Keep the LCD safe from vibration, shock and pressure.
 Black or white air-bubbles may be produced if the LCD is stored for long time in the
lower temperature or mechanical shocks are applied onto the LCD.
 In the case of storing for a long period of time for the purpose or replacement use,
the following ways are recommended.
-Store in a polyethylene bag with sealed so as not to enter fresh air outside in it.
-Store in a dark place where neither exposure to direct sunlight nor light is.
-Keep temperature in the specified storage temperature range.
-Store with no touch on polarizer surface by the anything else. If possible, store the LCD
in the packaging situation LCD when it was delivered.
12.7 Safety
 For the crash damaged or unnecessary LCD, it is recommended to wash off liquid crystal
by either of solvents such as acetone and ethanol an should be burned up later.
 In the case the LCD is broken, watch out whether liquid crystal leaks out or not. If your
hands touch the liquid crystal, wash your hands cleanly with water an soap as soon
as possible.
 If you should swallow the liquid crystal, first, wash your mouth thoroughly with water,
then drink a lot of water and induce vomiting, and then, consult a physician.
 If the liquid crystal should get in your eyes, flush your eyes with running water for at
least fifteen minutes.
 If the liquid crystal touches your skin or clothes, remove it and wash the affected part
of your skin or clothes with soap and running water. 28
