10.P recautions Relating Pr oduct 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 made 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 of 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 of synthetic 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) Conduc1tivity is not guaranteed for models that use metal holders 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 shorten their service life.

Page 17/18
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.

If the product is to be used in any of the above applications, we will need to enter into a separate product liability agreement.
We cannot accept responsibility for any defect, which may arise from additional manufacturing of the product (including disassembly and reassembly), after product delivery. We cannot accept responsibility for any defect, which may arise after the application of strong external force to the product. We cannot accept responsibility for any defect, which may arise due to the application of static electricity after the product has passed your company's acceptance inspection procedures. When the product is in CFL models, CFL service life and brightness will vary according to the performance of the inverter used, leaks, etc. We cannot accept responsibility for product performance, reliability, or defect, which may arise. We cannot accept responsibility for intellectual property of a third party, which may arise through the application of our product to your assembly with exception to those issues relating directly to the structure or method of manufacturing of our product. Optrex will not be held responsible for any quality guarantee issue for defect products judged as Optrex-origin longer than 2 (two) years from Optrex production or 1(one) year from Optrex, Optrex America, Optrex Europe, Display LC delivery which ever comes later.
