10.Precautions Relating Product Handling
The Following precautions will guide you in handling our product correctly.
1) Liquid crystal display devices
The liquid crystal display device panel used in the liquid crystal display module is ma d e of plate
glass. Avoid any strong mechanical shock. Should the glass break handle it with care.
The polarizer adhering to the surface of the LCD is made of a soft material.
Guard against scratching it.
2) Care o f the liquid crystal display module against static electricity discharge.
When working with the module, be sure to ground your body and any electrical equipment you may
be using. We strongly recommend the use of anti static mats ( made of rubber ), to protect work
tables against the hazards of electrical shock.
Avoid the use of work clothing made o f synthet ic fibers. We recommend cotton clothing or other
conductivity-treated fibers.
Slowly and carefully remove the protective film from the LCD module, since this operation can
generate static electricity.
3) When the LCD module alone must be stored for long periods of time:
Protect the modules from high temperature and humidity.
Keep the modules out of direct sunlight or direct exposure to ultraviolet rays.
Protect the modules from excessive external forces.
4) Use the module with a power supply that is equipped with an overcurrent protector circuit,
since the module is not provided with this protective feature.
5) Do not ingest the LCD fluid itself should it leak out of a damaged LCD module. Should hands
or clothing come in contact with LCD fluid, wash immediately with soap.
6) Co nduc1tivity is not guaranteed for models that use me tal hold ers where solder connections
between the metal holder and the PCB are not used. Please contact us to discuss appropriate
ways to assure conductivity.
7) For models which use CFL:
High voltage of 1000V or greater is applied to the CFL cable connector area.
Care should be taken not to touch connection areas to avoid burns.
Protect CFL cables from rubbing against the unit and thus causing the wire jacket to become worn.
The use of CFLs for extended periods of time at low temperatures will significantly shor ten their
service life.
DMC16433N (AO) No.2000-0120 OPTREX CORPORATION Page 15/15
OPTREX
8) For models which use touch panels:
Do not stack up modules since they can be damaged by components on neighboring modules.
Do not place heavy objects on top of the product. This could cause glass breakage.
9) For models which use COG,TAB,or COF:
The mechanical strength of the product is low since the IC chip faces out unprotected from the rear.
Be sure to protect the rear of the IC chip from external forces.
Given the fact that the rear of the IC chip is left exposed, in order to protect the unit from electrical
damage, avoid installation configurations in which the rear of the IC chip runs the risk of making
any electrical contact.
10) Models which use flexible cable, heat seal, or TAB:
In order to maintain reliability, do not touch or hold by the connector area.
Avoid any bending, pulling, or other excessive force, which can result in broken connections.
