quality ? all rights reserved 12/14 rev a z ethyl alcohol do not wipe the display surface with dry or hard materials that will damage the polarizer surface. do not use the following solvent: z water z aromatics do not wipe ito pad area with the dry or har d materials that will damage the ito patterns do not use the following solvent on t he pad or prevent it fr om being contaminated: z soldering flux z chlorine (cl) , salfur (s) if goods were sent without bei ng sili8con coated on the pad, ito patterns could be damaged due to the corrosion as time goes on. if ito corrosion happen by miss-handling or using some materials such as chlorine (ci), salfur (s) from customer, responsibility is on customer. 11.3 caution against static charge the lcd module use c-mos lsi driver s, so we recommended that you: connect any unused input terminal to vdd or v ss, do not input any signals before power is turned on, and ground your body, work/assembly areas, assembly equipment to protect against static electricity. 11.4 packing z module employ lcd elements and must be treated as such. z avoid intense shock and falls from a height. z to prevent modules from degr adation, do not operate or stor e them exposed direct to sunshine or high temperature/humidity 11.5 caution for operation z it is an indispensable condition to drive lcd?s within the specified voltage limit since the higher voltage then the limit cause the shorter lcd life. z an electrochemical reaction due to direct cu rrent causes lcd?s undesir able deterioration, so that the use of direct curr ent drive should be avoided. z response time will be extremely delayed at lower temperature then the operating temperature range and on the other hand at hi gher temperature lcd?s how dark color in them. however those phenomena do not mean ma lfunction or out of order with lcd?s, which will come back in the s pecified operation temperature. z if the display area is pushed har d during operation, some font will be abnormally displayed but it resumes normal condition after turning off once. z a slight dew depositing on termi nals is a cause for electro-c hemical reaction resulting in terminal open circuit. usage under the maximum operating temper ature, 50%rh or less is required. 11.6 storage in the case of storing for a long period of ti me for instance, for years for the purpose or replacement use, the followi ng ways are recommended. z storage in a polyethylene bag with the opening sealed so as not to enter fresh air outside in it . and with no desiccant. z placing in a dark place where neither exposure to direct sunlight nor light?s keeping the storage temperature range. z storing with no touch on polarizer surface by the anything else. [it is recommended to store them as they have been contained in the inner container at the time of delivery from us 11.7 safety z it is recommendable to crash damaged or unneces sary lcd?s into pieces and wash off liquid
quality ? all rights reserved 13/14 rev a crystal by either of solvents such as ac etone and ethanol, which should be burned up later. z when any liquid leaked out of a damaged glass cell comes in contact with your hands, please wash it off well with soap and water 12. precaution for use 12.1 a limit sample should be provided by the both parties on an occasion when the both parties agreed its necessity. judgment by a limit sample s hall take effect after the limit sample has been established and confirmed by the both parties. 12.2 on the following occasions, the handing of pr oblem should be decided through discussion and agreement between responsible of the both parties. z when a question is arisen in this specification z when a new problem is arisen which is not specified in th is specifications z when an inspection specificat ions change or operating cond ition change in customer is reported to skyworthlcd , and some problem is arisen in this specific ation due to the change z when a new problem is arisen at the customer?s operating set for sample evaluation in the customer site.
