12.0 PRECAUTION FOR USING LCM
1. When design the product with this LCD Module, make sure the viewing angle matches to its purpose of usage.
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. Although the polarizer of this LCD Module has the anti-glare coating, always be careful not to scratch its
surface. Use of a plastic cover is recommended to protect the surface of polarizer.
4. If the LCD module is stored at below specified temperature, the LC material may freeze and be deteriorated. If
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 off immediately as those may leave stains or cause color changes 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 latchup
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 modify the PCB by drilling extra holes, changing its outline, moving its components or modifying its
pattern.
d) Do not touch the elastomer connector; especially insert a backlight panel (for example, EL).
e) When mounting a LCM makes 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.
f) Avoid pressing on the metal bezel, otherwise the elastomer connector could be deformed and lose
contact, resulting in missing pixels.
9. Static Electricity
a) Operator
Ware 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: 1x108 ohm).
