4.2 Resetting the LCD module
The LCD module should be initialized bu using /RES terminal.
While turning on the VDD and VSS power supply, maintain /RES terminal at LOW level, After the
Power supply stabilized, release the reset terminal(/RES = High)

6. Handling Precautions
6.1 Mounting method
A panel of LCD module made by our company consists of two thin glass plates with polarizers that easily get damaged.
And since the module in so constructed as to be fixed by utilizing fitting holes in the printed circuit board (PCB), extreme care
should be used when handling the LCD modules.
6.2 Cautions of LCD handling and cleaning
When cleaning the display surface, use soft cloth with solvent (recommended below) and wipe lightly.
-Isopropyl alcohol
-Ethyl alcohol
-Trichlorotriflorothane
Do not wipe the display surface with dry or hard materials that will damage the polarizer surface.
Do not use the following solvent:
-Water
-Ketene
-Aromatics
6.3 Caution against static charge
The LCD module use C-MOS LSI drivers. So we recommend 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.
6.4 Packaging
-Module employs 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.
6.5 Caution for operation
-It is an indispensable condition to drive LCD module within the limits of the specified voltage since the higher voltage over the
limits may cause the shorter life of LCD module.
-An electrochemical reaction due to DC (direct current) causes LCD undesirable deterioration so that the uses of DC (direct
current) drive should be avoided.
-Response time will be extremely delayed at lower temperature than the operating temperature range and on the other hand at
higher temperature LCD module may show dark color in them. However those phenomena do not mean malfunction or out of
order of LCD module, which will come back in the specified operating temperature.
6.6 Storage
In the case of storing for a long period of time, the following ways are recommended:
-Storage in polyethylene bag with the opening sealed so as not to enter fresh air outside in it. And with not desiccant.
-Placing in a dark place where neither exposure to direct sunlight nor light is. Keeping the storage temperature range.
-Storing with no touch on polarizer surface by any thing else.
6.7 Safety
-It is recommendable to crash damaged or unnecessary LCD into pieces and to 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 at once with
soap and water.
