11.Product Handling Cautions
In order to use the products properly please note the following precautions. 1) For LCD screen ? LCD particles used in LCD module is made into form of glass board. Do not apply any strong physical shock. If it cracks, handle with extra caution to avoid any harm. ? The polarizer attached on the surface of LCD particles are composed by soft materials. Please do not scratch them.
2) Handling LCD module (static electricity countermeasure) ? Please ground all human bodies and electrical facilities. Also on the operation line, anti-static electricity mat (rubber) is recommended to avoid electric shock in case of accident. ? Working uniform should avoid synthetic fiber and recommend the use of cotton or non-electrical conducting fiber. ? When removing protective film from LCD panel, please remove it slowly to avoid development of static electricity. 3) For Storing Single LCD module for long term ? Do not store under high temperature and high humidity. ? Do not expose the module to direct sunlight or intensive ultraviolet rays for many hours. ? Avoid any force applied from external environment. 4) LCD module does not have circuit for over current protection. power supply with over current protection. For in case of accident, please use
5) If LCD panel breaks, it is possible that the liquid crystal leaks from the panel. Avoid putting it into eyes or mouth. When liquid crystal sticks on hands, clothes, or feet. Wash it out immediately with soap. 6) When using product with metal holder, if metal holder and the body are not soldered, sooth electric flow is not guaranteed. To secure the flows of electricity, please consult. 7) For products that requires the use of C F L ? On the connection of CFL cable more then 1000 v high voltage is applied. Please handle with care to avoid any burn upon contact. ? Please be careful if overcoat of CFL cable is in the status of abrasion by the contact with the system. ? Continuous use of CFL at low temperature, will shorten longevity of CFL compared to it's use at room temperature. 8) For products that uses touch panel ? Do not stack panel on top of each other. There may be possibility of harm caused by the edge of panel. ? Do not place any heavy objects above panel.

9) For product that uses COG, TAB, and COF ? The back side of IC hip is exposed and has low intensity. Upon handling, do not apply powerful pressure to the IC chip. ? IC chip backside is exposed and should not be equipped with any setup that releases electrical contact to prevent electrical damage. Also to prevent unintentional function by light and to keep it's electrical characteristics, set up to avoid exposure to light. 10) For product that uses FPC, heal seal and TAB ? To maintain reliability, do not hold onto connection section. Do not bend or pull lines with strong power. It could snap the lines.
12. Condition for Guarantee.
Our product is designed and manufactured by your specification requirement as a part for final electrical products. We will guarantee the product has no sign of defect and meet all qualifications of your request. However, if the final product was not for common household use, but instead used for medical, nuclear controller, aviation, disaster prevention or any other products that require extreme reliability, we can not be held responsible for any quality guarantee issue. If the product was placed for any of the use above, we ask for revision on our contract for manufacturing this product. 1) After delivery, any modification (including restructure and taking apart) of the product we can not hold any responsibility for quality guarantee issue. 2) Any damage caused by the outside force, we can not hold any responsibility for quality guarantee issue. 3) After completing all product inspection and after delivery from the factory, any static electricity applied on product, we can not hold any responsibility for quality guarantee issue. 4) Upon using product with CFL, longevity and luminance may altar by the performance of inverter or leakage. We can not hold any responsibility for quality guarantee issue by performance or reliability of final product. 5) Any product that uses our product within, we will not hold any responsibility for any problems that has no relationship with the structure or performance of our product.
