5. PRECAUTIONS FOR USING LCD MODULES
Installing LCD Modules
The hole in the printed circuit board is used to fix LCM as shown in the picture below. Attend to the following items when
installing the LCM.
1)
Cover the surface with a transparent protective plate to protect the polarizer and LC cell.
2)
When assembling the LCM into other equipment, the spacer to the bit between the LCM and the fitting plate
should have enough height to avoid causing stress to the module surface, refer to the individual specifications for
measurements. The measurement tolerance should be
±0.1mm.
Precaution for Handing LCD Modules
Since LCM has been assembled and adjusted with a high degree of precision, avoid applying excessive shocks to the module or
making any alterations or modifications to it.
1)
Cover the surface with a transparent protective plate to protect the polarizer and LC cell.
2)
Do not alter, modify or change the shape of the tab on the metal frame.
3)
Do not make extra holes on the printed circuit board, modify its shape or change the positions of components to
be attached.
4)
Do not damage or modify the pattern writing on the printed circuit board.
5)
Absolutely do not modify the zebra rubber strip (conductive rubber) or heat seal connector.
6)
Except for soldering the interface, do not make any alterations or modifications with a soldering iron.
7)
Do not drop, bend or twist LCM.
Electro-Static Discharge Control
Since this module uses a CMOS LSI, the same careful attention should be paid to electrostatic discharge as for an ordinary
CMOS IC.
1)
Make certain that you are grounded when handing LCM.
2)
Before remove LCM from its packing case or incorporating it into a set, be sure the module and your body have
the same electric potential.
3)
When soldering the terminal of LCM, make certain the AC power source for the soldering iron does not leak.
4)
When using an electric screwdriver to attach LCM, the screwdriver should be of ground potentiality to minimize
as much as possible any transmission of electromagnetic waves produced sparks coming from the commutator of
the motor.
5)
As far as possible make the electric potential of your work clothes and that of the work bench the ground
potential.
6)
To reduce the generation of static electricity be careful that the air in the work is not too dried. A relative
humidity of 50%-60% is recommended.
Precaution for soldering to the LCM
1)
Observe the following when soldering lead wire, connector cable and etc. to the LCM.
a) Soldering iron temperature : 280
°C ± 10°C.
b) Soldering time : 3-4 sec.
2)
Solder : eutectic solder.
