14. 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 handing,
(1). Keep the temperature within range of use and storage.
Excessive temperature and humidity could cause
polarization degredation, polarizer peel off or bubble.
(2). Do not contact the exposed polarizers with anything
harder than an HB pencil lead. To clean dust off the
display surface, wipe gently with cotton, chamois or other
soft material soaked in petroleum benzin.
(3). Wipe off saliva or water drops immediately. Contact
with water over a long period of time may cause polarizer
deformation or color fading, while an active LCD with
water condensation on its surface will cause corrosion of
ITO electrodes.
(4). Glass can be easily chipped or cracked from rough
handling, especially at corners and edges.
(5). 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 modifications. The following should be noted.
(1). Do not tamper in any way with the tabs on the metal
frame.
(2). Do not modify the PCB by drilling extra holes,
changing its outline, moving its components or modifying
its pattern.
(3). Do not touch the elastomer connector, especially
insert an backlight panel (for example, EL).
(4). 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.
(5). 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
(1). 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.
(2). The modules should be kept in antistatic bags or other
containers resistant to static for storage.
(3). Only properly grounded soldering irons should be
used.
(4). If an electric screwdriver is used, it should be well
grounded and shielded from commutator sparks.
(5) The normal static prevention measures should be
observed for work clothes and working benches; for the
latter conductive (rubber) mat is recommended.
(6). Since dry air is inductive to static, a relative
humidity of 50-60% is recommended.
2.3
(1). Solder only to the I/O terminals.
(2). Use only soldering irons with proper grounding
and no leakage.
(3). Soldering temperature : 280°C ± 10°C
(4). Soldering time: 3 to 4 sec.
(5). Use eutectic solder with resin flux fill.
(6). If flux is used, the LCD surface should be covered
to avoid flux spatters. Flux residue should be removed
after wards.
2.4 Operation
(1). The viewing angle can be adjusted by varying the
LCD driving voltage V0.
(2). Driving voltage should be kept within specified
range; excess voltage shortens display life.
(3). Response time increases with decrease in
temperature.
(4). Display may turn black or dark blue at
temperatures above its operational range; this is
(however not pressing on the viewing area) may cause
the segments to appear “fractured”.
(5). Mechanical disturbance during operation (such as
pressing on the viewing area) may cause the segments to
appear “fractured”.
2.5 Storage
If any fluid leaks out of a damaged glass cell, wash off
any human part that comes into contact with soap and
water. Never swallow the fluid. The toxicity is extremely
low but caution should be exercised at all the time.
2.6 Limited Warranty
Unless otherwise agreed between DATA IMAGE and
customer, DATA IMAGE will replace or repair any of its
LCD and LCM which is found to be defective
electrically and visually when inspected in accordance
with DATA IMAGE acceptance standards, for a period
on one year from date of shipment. Confirmation of such
date shall be based on freight documents. The
warranty liability of DATA IMAGE is limited to repair
and/or replacement on the terms set forth above. DATA
IMAGE will not responsible for any subsequent or
consequential events.
