SPECIFICATIONS FOR LIQUID CRYSTAL DISPLAY MODULE
MODEL NO: 12864-12
3) If soldering flux is used, be sure to remove any remaining flux after finishing to soldering operation. (This does
not apply in the case of a non-halogen type of flux.) It is recommended that you protect the LCD surface with a
cover during soldering to prevent any damage due to flux spatters.
4) When soldering the electroluminescent panel and PC board, the panel and board should not be detached more
than three times. This maximum number is determined by the temperature and time conditions mentioned above,
though there may be some variance depending on the temperature of the soldering iron.
5) When remove the electroluminescent panel from the PC board, be sure the solder has completely melted, the
soldered pad on the PC board could be damaged.
Precautions for Operation
1) Viewing angle varies with the change of liquid crystal driving voltage (VO). Adjust VO to show the best contrast.
2) Driving the LCD in the voltage above the limit shortens its life.
3) Response time is greatly delayed at temperature below the operating temperature range. However, this does not
mean the LCD will be out of the order. It will recover when it returns to the specified temperature range.
4) If the display area is pushed hard during operation, the display will become abnormal. However, it will return to
normal if it is turned off and then back on.
5) Condensation on terminals can cause an electrochemical reaction disrupting the terminal circuit. Therefore, it
must be used under the relative condition of 40°C , 50% RH.
6) When turning the power on, input each signal after the positive/negative voltage becomes stable.
Safety
• If the LCD panel breaks, be careful not to get the liquid crystal in your mouth. If the liquid crystal touches your skin
or clothes, wash it off immediately using soap and plenty of water.
Handling
• The display panel is made of glass. Do not subject it to a mechanical shock by dropping it or impact.
• If the display panel is damaged and the liquid crystal substance leaks out, be sure not to get any in your mouth. If the
substance contacts your skin or clothes, wash it off using soap and water.
• Do not apply excessive force to the display surface or the adjoining areas since this may cause the color tone to vary.
• The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle this polarizer
carefully.
• If the display surface becomes contaminated, breathe on the surface and gently wipe it with a soft dry cloth. If it is
heavily contaminated, moisten cloth with one of the following solvents :
o Isopropyl alcohol
o Ethyl alcohol
• Solvents other than those above-mentioned may damage the polarizer. Especially, do not use the following.
o Water
o Ketone
o Aromatic solvents
• Exercise care to minimize corrosion of the electrode. Corrosion of the electrodes is accelerated by water droplets,
moisture condensation or a current flow in a high-humidity environment.
• Install the LCD Module by using the mounting holes. When mounting the LCD module make sure it is free of
twisting, warping and distortion. In particular, do not forcibly pull or bend the I/O cable or the backlight cable.
• Do not attempt to disassemble or process the LCD module.
• NC terminal should be open. Do not connect anything.
• If the logic circuit power is off, do not apply the input signals.
