TO BE VERY CAREFUL !
The LCD driver ICs are made by CMOS process, which are very easy to be damaged
by static charge, make sure the user is grounded when handling the LCM.

Reset can be initialized system by setting RES terminal at low level when turning power on.
receiving instruction from MPU. When RES become low, following procedure is occured.
1.Display OFF
2.Display start line register become set by 0.
While RES is low, any instruction except status read can be accepted. Reset status appers at
DB4. After DB4 is low, any instruction can be accepted.

HANDLING PRECAUTION
1. Mounting Method
The panel of the LCD Module consists of two thin glass plates with polarizes 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.
2. Caution of LCD handling & 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 polarize
surface.
Do not use the following solvent:
-Water
-Kettle
-Aromatics
3. Caution against static charge
The LCD Module use C-MOSLSI drivers, so we recommend end 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.
4. Packaging
-Modules use LCD elements, and must be treated as such. Avoid in tense 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.

SUNLIKE DISPLAY
Model No :SG12864A
5. Caution for operation
-It is indispensable to drive LCD’s with in the specified voltage limit since the higher voltage
than the limit shorten LCD life.
An electrochemical reaction due to direct current causes LCD deterioration, Avoid the use of
direct current drive.
-Response time will be extremely delayed at lower temperature than the operating temperature
range and on the other hand at higher temperature LCD's show 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 operating temperature range.
- 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 relative condition of 40 ℃, 50%RH or less is required.
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 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 is. Keeping
temperature in the specified 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)
7. Safety
- It is recommendable 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 well with soap and water.
