11. precaution in design 11.1 mounting method since the module is so constructed as to be fixed by utilizing fitting holes in the module as shown below, it is necessary to take consideration the follwing items on attachment to a frame. (1 ) use of protective plate, made of an acrylic plate, etc, in order to protect a polarizer and lc cell. (2 ) to prevent the module cover from being pressed, the spacers between the module and the fitting plates should be longer than 0.5mm. (3 ) we recommend you to use protective spacer as figure for protecting the module from any kind of shock to your set. 11.2 lc driving voltage (vee) and viewing angle range. settting vee out of the recommended condition will be a cause for a change of viewing angle range. example of mounting location of spacers customer's housing cfl spacer the module protective plate unit:mm scale:nts spacer protective spacer 119.0+/-0.3 197.0+/-0.3 238.0+/-0.3 30+/-0.3 71.0 0.3 90+/- 0.3 150 .0 +/- 0.3 protective spacer 4- f 5.0 spacer 4- f 7.0 164.0 0.3 cfl side kaohsiung hitachi electronics co.,ltd. date mar.27.?98 7b64ps 2711-LMG5278XUFC-00T-2 page 11-1/3 sh. no.
11.3 caution against static charge as this module is provided with c-mos lsi, the care to take such a precaution as to grounding the operator?s body is required when handling it. 11.4 power on sequence input signals should not be applied to lcd module before power supply voltage is applied and reaches to specified voltage (5+/-0.25v). if above sequence is not kept, c-mos lsis of lcd modules may be damaged due to latch up problem. 11.5 packaging (1 ) no. leaving products is preferable in the place of high humidity for a long period of time. for their storage in the place where temperature is 35 c or higher, special care to prevent them from high humidity is required. a combination of high temperature and high humidity may cause them polarization degradation as well as bubble generation and polarizer peel-off. please keep the temperature and humidity within the specified range for use and storing. (2 ) since upper polarizers and lower aluminum plates tend to be easily damaged, they should be handled with full care so as not to get them touched, pushed or rubbed by a piece of glass, tweezers and anything else which are harder than a pencil lead 3h. (3 ) as the adhesives used for adhering upper/lower polarizers and aluminum plates are made of organic substances which will be deteriorated by a chemical reaction with such chemicals as acetone, tuluene ethanole and isopropylalcohol. the following solvents are recommended for use: normal hexane please contact us when it is necessary for you to use chemicals other than the above. (4 ) lightly wipe to clean the dirty surface with absorbent cotton waste or other soft material like chamois, soaked in the chemicals recommended without scrubbing it hardly. to prevent the display surface from damage and keep the appearance in good state, it is sufficient, in general, to wipe it with absorbent cotton. (5 ) immediately wipe off asliva or water drop attached on the display area because its long period adherance may cause deformation or faded color on the spot. (6 ) fogy dew deposited on the surface and contact terminals due to coldness will be a cause for polarizer damage, stain and dirt on product. when necessary to take out the products from some place at low temperature for test , etc. it is required for them to be warmed up in a container once at the temperature higher than that of room. kaohsiung hitachi electronics co.,ltd. date mar.27.?98 7b64ps 2711-LMG5278XUFC-00T-2 page 11-2/3 sh. no.
(7 ) touching the display area and contact terminals with bare hands and contaminating them are prohibited, because the stain on the display area and poor insulation between terminals are often caused by being touched by bare hands. (there are some cosmetics detrimental to polarizers.) (8 ) in general the quality of glass is fragile so that it tends to be cracked or chipped in handling, specially on its periphery please be careful not give it sharp shock caused by dropping down, ect. 11.6 caution for operation (1 ) it is an indispensable condition to drive lcd?s within the specified voltage limit since the higher voltage than the limit causes the shorter lcd life. an electrochemical reaction due to direct current causes lcd?s undesirable deterioration, so that the use of direct current driver should be avoided. (2) response time will be extremely delayed at lower temperature than the operating temperature range and on the other hand at higher temperature lcd?s show dark bule color in them. .however those phenomena do not mean inpediment or out of order with lcd?s which will come back in the specified operating temperature range. (3 ) if the display area is pushed hard during operation, some font will be abnormally displayed but it resumes normal condition after turning off once. (4 ) a slight dew depositing on terminals is a cause for electrochemical reaction resulting in terminal open circuit. usage under the relative condition of 40 c 50%rh less is required. 11.7 storage in case of storing for a long period of time (for instance , for years) for the purpose of replacement use , the following ways are recommended. (1 ) storage in a polyethylene bag with the opening sealed so as not to enter fresh air outside in it, and with no desiccant. (2 ) the placing in a dark room where neither exposure to direct sunlight nor light is, keeping temperature in the range from 0 c to 35 c. (3 ) storing with no touch on polarizer surface by anything else. (it is recommended to stone them as they have been contained in the inner container at the time of delivery from us.) 11.8 safety (1 ) it is recommendable to crash damaged or unnecessary lcd?s into pieces and wash off liquid crystal by either of solvents such as acetone and ethanol, which shoud be burned up later. (2 ) when any liquid leaked out of a damaged glass gall comes in contact with your hands, please wash it off well with soap and water. kaohsiung hitachi electronics co.,ltd. date mar.27.?98 7b64ps 2711-LMG5278XUFC-00T-2 page 11-3/3 sh. no.

13. precautipon for use (1 ) a limit sample should be provided by the both parties on an occasion when the both parties agreed its necessity. judgement by a limit sample shall take effect after the limit sample has been eatablished and confirmed by the both parties. (2 ) on the following occasions, the handling of the problem should be decided through discussion and agreement between responsible persons of the both parties. (1 ) when a question is arisen in the specifications. (2 ) when a new problem is arisen which is not specified in this specifications. (3 ) when an inspection specifications change or operating condition change in customer is reported to hitachi, and some problem is arisen in this specification due to the change. (4 ) when a new problem is arisen at the customer?s operating set for sample evaluation in the customer site. (3 ) regarding the treatment for maintenance and repairing, both parties will disscuss it in six months later after latest delivery of this product. the precaution that should be observed when handling lcm have been explaind above. if any points are unclear of if you have any requests, please contact hitachi. kaohsiung hitachi electronics co.,ltd. date mar.27.?98 7b64ps 2713-LMG5278XUFC-00T-2 page 13-1/1 sh. no.
