13. Precaution for using LCM
1. Liquid Crystal Display (LCD)
LCD is made up of glass, organic sealant, organic fluid and
polymer based polarizers. The following precautions should
be taken when handling.
b) Keep the temperature within the range of use and
storage. Excessive temperature and humidity
could cause polarization degredation, polarizer
peel off or bubble.
c) Do not contact the exposed polarizer with
anything harder than HB pencil lead. To clean
dust off the display surface, wipe gently with
cotton, chamois or other soft material soaked in
petroleum benzin.
d) Wipe off saliva or water drops immediately.
Contact with water over a long period of time
may cause polarizer deformation or colour
fading, while an active LCD with water
condensation on its surface will cause corrosion
of ITO electrodes.
e) Glass can be easily chipped or cracked from
rough handling, especially at corners and edges.
f) Do not drive LCD with DC voltage.
2. Liquid Crystal Display Modules.
2.1 Mechanical Considerations
LCM are assembled and adjusted with a high
degree of precision. Avoid excessive shocks and
do not make any alterations or modification. The
following should be noted.
a) Do not tamper in any way with the tabs
on the metal frame.
b) Do not modify the PCB by drilling
extra holes, changing its outline,
moving its component or modifying its
pattern.
c) Do not touch the elastomer connector,
especially insert a backlight panel (for
example, EL)
d) When mounting a LCM make sure that
the PCB is not under any stress such as
bending or twisting. Elastomer contacts
are very delicate and missing pixels
could result from slight dislocation of
any of the elements.
a) Avoid pressing on the metal bezel,
otherwise the elastomer connector
could be deformed and lose contact,
resulting in missing pixels.
2.2 Static Electricity
LCM contains CMOS LSI’s and the same
precaution for such devices should apply, namely
a) The operator should be grounded whenever
he/she comes into contact with the module.
Never touch any of the conductive parts
such as the LSI pads, the copper leads on the
PCB and the interface terminals with any
parts of the human body.
b) The modules should be kept in antistatic
bags or other containers to static for storage.
c) Only properly grounded soldering irons
should be used.
d) If an electric screwdriver is used, it should
be well grounded and shielded from
commutator spark.
e) The normal static prevention measures
should be observed for work clothes and
working benches, the latter conductive
(rubber) mat is recommended.
f) Since dry air is inductive to statics, a relative
humidity of 50-60% is recommended.
2.3 Soldering
a) Solder only to the I/O terminals.
b) Use only soldering irons with proper
grounding and no leakage.
c) Soldering temperature: 280 °C
d) Soldering time: 3 to 4 sec
e) Use eutectic solder with resin flux fill.
f) If flux is used, the LCD surface should be
covered to avoid flux spatters. Flux residue
should be removed afterwards.

2.4 Operation
a) The contras can be adjusted by varying the
LCD driving voltage V0
b) Driving voltage should be kept within
specified range, excess voltage shortens
display life.
c) Response time increases with decrease in
temperature.
d) Display may turn black or dark blue at
temperature above its operational range, this
is (however not pressing on the viewing
area) may cause the segments to appear
“fractured”.
