6. PRECAUTION FOR USING LCM
1. When desi
nthe
roduct with this LCD Module, make sure the viewin
an
le matches to its
ur
ose o
usa
e.
2. As LCD panel is made of glass substrate, Dropping the LCD module or banging it against hard objects may cause
cracking or fragmentation. Especially at corners and edges.
3.
lthou
h the polarize
o
this LCD Module has the anti-
lare coatin
,alwa
s be careful not to scratch its surface.
Use of a plastic cover is recommended to protect the surface of polarizer.
4. I
the LCD module is stored at below specified temperature, the LC material ma
freeze and be deteriorated. I
it is
stored at above specified temperature, the molecular orientation of the LC material may change to Liquid state and it
may not revert to its original state. Excessive temperature and humidity could cause polarizer peel off or bubble.
Therefore, the LCD module should always be stored within specified temperature range.
5. Saliva or water droplets must be wiped of
immediatel
as those ma
leave stains o
cause colo
chan
es if
remained for a long time. Water vapor will cause corrosion of ITO electrodes.
6. If the surface of LCD panel needs to be cleaned, wipe it swiftly with cotton or other soft cloth. If it is not still clean
enough, blow a breath on the surface and wipe again.
7. The module should be driven according to the specified ratings to avoid malfunction and permanent damage.
Applying DC voltage cause a rapid deterioration of LC material. Make sure to apply alternating waveform by
continuous application of the M signal. Especially the power ON/OFF sequence should be kept to avoid latch-up of
driver LSIs and DC charge up to LCD panel.
8. Mechanical Considerations
a) LCM are assembled and adjusted with a high degree of precision. Avoid excessive shocks and do not make
any alterations or modifications. The following should be noted.
b) Do not tamper in any way with the tabs on the metal frame.
c
Do not modif
the PCB b
drillin
extra holes, chan

its outline, movin
its components o
modif
in
its
pattern.
d
Do not touch the elastome
connector; especiall
insert a backli
ht panel
fo
example, EL
.
e
When mountin
a LCM makes sure that the PCB is not under an
stress such as bendin
o
twistin
.
Elastomer contacts are very delicate and missing pixels could result from slight dislocation of any of the
elements.
f
void pressin
on the metal bezel, otherwise the elastomer connecto
could be deformed and lose contact,
resulting in missing pixels.
9. Static Electricit
a) Operator
Wear the electrostatics shielded clothes because human body may be statically charged if not ware shielded clothes.
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
Equipment
There is a possibility that the static electricity is charged to the equipment, which has a function of peeling or friction
action (ex: conveyer, soldering iron, working table). Earth the equipment through proper resistance (electrostatic earth:
1x108ohm).
Only properly grounded soldering irons should be used.
If an electric screwdriver is used, it should be well grounded and shielded from commutator sparks.
The normal static prevention measures should be observed for work clothes and working benches; for the latter
conductive (rubber) mat is recommended.
c) Floor
Floor is the important part to drain static electricity, which is generated by operators or equipment.
There is a possibility that charged static electricity is not properly drained in case of insulating floor. Set the electrostatic
earth (electrostatic earth: 1x108ohm).
d
Humidit
Proper humidity helps in reducing the chance of generating electrostatic charges. Humidity should be kept over 50%RH.
e
Transportation/stora
e
The storage materials also need to be anti-static treated because there is a possibility that the human body or storage
materials such as containers may be statically charged by friction or peeling.
The modules should be kept in antistatic bags or other containers resistant to static for storage.
f
Solderin
Solder only to the I/O terminals. Use only soldering irons with proper grounding and no leakage.
Soldering temperature : 280°C±10°C
Soldering time: 3 to 4 sec.
Use eutectic solder with resin flux fill.
If flux is used, the LCD surface should be covered to avoid flux spatters. Flux residue should be removed afterwards.
