Handling Precautions
Mounting method
The LCD panel of SC LCD LCD module consists of two thin glass plates with polarizes which
easily be damaged. And since the module in so constructed as to be fixed by utilizing fitting holes
in the printed circuit board.
Extreme care should be needed when handling the LCD modules.
8.2 Caution of LCD handling and cleaning
When cleaning the display surface, Use soft cloth with solvent
[recommended below] and wipe lightly
? Isopropyl alcohol
? Ethyl alcohol
Do not wipe the display surface with dry or hard materials that will damage the polarizer
surface.
Do not use the following solvent:
? Water
? Aromatics
Do not wipe ITO pad area with the dry or hard materials that will damage the ITO patterns
Do not use the following solvent on the pad or prevent it from being contaminated:
? Soldering flux
? Chlorine (Cl) , Salfur (S)
If goods were sent without being sili8con coated on the pad, ITO patterns could be damaged
due to the corrosion as time goes on.
If ITO corrosion happen by miss-handling or using some materials such as Chlorine (CI),
Salfur (S) from customer, Responsibility is on customer.
8.3 Caution against static charge
The LCD module use C-MOS LSI drivers, so we recommended that you:
Connect any unused input terminal to Vdd or Vss, do not input any signals before power is
turned on, and ground your body, work/assembly areas, assembly equipment to protect against
static electricity.
8.4 packing
? Module employ LCD elements 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 direct to
sunshine or high temperature/humidity
8.5 Caution for operation
? It is an indispensable condition to drive LCD’s within the specified voltage limit since the
higher voltage then the limit cause the shorter LCD life.
? An electrochemical reaction due to direct current causes LCD’s undesirable deterioration, so
that the use of direct current drive should be avoided.
? Response time will be extremely delayed at lower temperature then the operating
temperature range and on the other hand at higher temperature LCD’s how dark color in
them. However those phenomena do not mean malfunction or out of order with LCD’s,
which will come back in the specified operation temperature.
? If the display area is pushed hard during operation, some font will be abnormally displayed
but it resumes normal condition after turning off once.
? A slight dew depositing on terminals is a cause for electro-chemical reaction resulting in
terminal open circuit.
Usage under the maximum operating temperature, 50%Rh or less is required.
8.6 storage
In the case of storing for a long period of time for instance, for years for the purpose or
replacement use, the following ways are recommended.
? Storage in a polyethylene bag with the opening sealed so as not to enter fresh air outside in
it . And with no desiccant.
? Placing in a dark place where neither exposure to direct sunlight nor light’s keeping the
storage temperature range.
? Storing with no touch on polarizer surface by the anything else.
[It is recommended to store them as they have been contained in the inner container at the
time of delivery from us
8.7 Safety
? It is recommendable to crash damaged or unnecessary LCD’s into pieces and wash off liquid
crystal by either of solvents such as acetone and ethanol, which should be burned up later.
? When any liquid leaked out of a damaged glass cell comes in contact with your hands, please
wash it off well with soap and water
9. Precaution For Use
9.1
A limit sample should be provided by the both parties on an occasion when the both parties
agreed its necessity. Judgment by a limit sample shall take effect after the limit sample has been
established and confirmed by the both parties.
9.2
On the following occasions, the handing of problem should be decided through discussion and
agreement between responsible of the both parties.
? When a question is arisen in this specification
? When a new problem is arisen which is not specified in this specifications
? When an inspection specifications change or operating condition change in customer is
reported to SC LCD , and some problem is arisen in this specification due to the change
? When a new problem is arisen at the customer’s operating set for sample evaluation in the
customer site.
