1. Handling Precaution
1-1. MOUNTING METHOD
The panel of the LCD module consists of two thin glass plates with polarizers which easily get damaged since the module is fixed by utilizing fitting holes in the printed circuit board. Extreme care should be taken when handling the LCD modules.
1-2. CAUTION OF LCD HANDLING & CLEANING
When cleaning the display surface. Use soft cloth with solvent (recommended as below) and wipe lightly.
-Isopropyl alcohol
-Ethyl alcohol
Do not wipe the display surface with dry or hard materials that will damage the polarizers surface.
Do not use the following solvents:
-Water
-Ketones solvents
-Aromatics solvents
1-3. CAUTION AGAINST STATIC CHARGE
The LCD modules use C-MOS LSI drivers. So we recommend 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 table and assembly equipment to protect against static electricity.
1-4. PACKAGING
Modules use LCD elements, Do not subject to excessive shocks by dropping the units.
-To prevent modules from degradation, do not operate or store them in sunshine or at high temperature/humidity.
1-5. CAUTION FOR OPERATION
It is indispensable to drive LCM within the specified voltage limit since the higher voltage than the limit will shortens LCM life.
Response time will be extremely delayed at lower temperature than in the specified operating temperature range and on the other hand at higher temperature LCD will show dark color in them.
However those phenomena do not mean malfunction or out of order with LCD, which will come back in the specified operating temperature range.
If the display area is pushed hard during operation. Some font will be abnormally displayed but it resumes normal condition once turning off.
A slight dew depositing on terminals may cause Electro-chemical reaction resulting in terminal open circuit. Under the maximum operating temperature, 50%RH or less is required.
1-6. STORAGE
In the case of storing for a long period of time (for instance, for years) for the purpose of replacement use， the following ways are recommended.
-Storage in a anti-static 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 to light, keeping temperature in the specified storage temperature range.
-Storing with no touch on polarizers surface by anything else. (it is recommended to store them as they have been contained in the inner container ).
1-7. SAFETY
It is recommended to crash damaged or unnecessary LCD into pieces and wash off liquid crystal by using solvents such as acetone and ethanol, which should be burned up later.
When any liquid crystal leaked out of a damaged glass cell comes in contact with your hands, please wash it off immediately with soap and water.
2. Precaution for Use
2-1. A limit sample should be provided by the both parties on the occasion when the both parties agree its necessity.
Judgment by a limit sample shall take effect after the limit sample has been established and confirmed by the both parties.
2-2. On the following occasions, the handling of problem should be decided through discussion and agreement between representative 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 specification change or operating condition change in customer is reported to manufacturer 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 size.
