PRECAUTION IN DESIGN 11.1 MOUNTING METHOD SINCE THE MODULE IS SO CONSTRUCTED AS TO BE FIXED BY UTILIZING FITTING HOLES IN THE PRINTED CIRCUIT BOARD AS SHOWN BELOW, IT IS NECESSARY TO TAKE CONSIDERATION THE FOLLOWING ITEMS ON ATTACHMENT TO A FRAME. PROTTECTIVE PLATE THE MODULE SPACER CUSTOMER'S HOUSING SPACER PROTECTIVE SPACER EXAMPLE OF MOUNTING 139.0+/-0.3 69.5+/-0.3 79.0+/-0.3 37.0+/-0.3 74.0+/-0.3 30.0+/-0.3 UNIT:mm SCALE:NTS SPACER 4-φ7.0 PROTECTIVE SPACER 4-φ5.0 LOCATION OF SPACERS (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 SHOUD BE LONGER THAN 0.5mm. (3) WE RECOMMEND YOU TO USE PROTECTIVE SPACER AS FIGURE FOR PROTECTING LCD MODULE FROM ANY KIND OF SHOCK TO YOUR SET. 11.2 LC DRIVING VOLTAGE(VEE) AND VIEWING ANGLE RANGE. SETTING VEE OUT OF THE RECOMMENDED CONDITION WILL BE A CAUSE FOR A CHANGE OF VIEWING ANGLE RANGE. Sh. KAOHSIUNG HITACHI DATE FEB.10.’98 7B64PS 2711-LMG7520RPFC-4 PAGE 11-1/4 No. ELECTRONICS CO.,LTD. 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 LSI 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 POLARIZES AND ALUMINUM PLATES ARE MADE OF ORGANIC SUBSTANCES WHICH WILL BE DETERIORATED BY A CHEMICAL REACTION WITH SUCH CHEMICALS AS ACETONE, TULUENE ETHANOLE AND ISOPROPYLALCOHIL. 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. Sh. KAOHSIUNG HITACHI DATE FEB.10.’98 7B64PS 2711-LMG7520RPFC-4 PAGE 11-2/4 No. ELECTRONICS CO.,LTD. (5) IMMEDIATELY WIPE OFF SALIVA OFF SALIVA OR WATER DROP ATTACHED ON THE DISPLAY AREA BECAUSE ITS LONG PERIOD ADHERENCE MAY CAUSE DEFORMATION OR FADED COLOR ON THE SPOT. (6) FOGY DEW DEPOSITED ON THE SURFACE AND CONTACT TERMINALS DUE TO COLDNESS WILL BE 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 THEM TO BE WARMED UP IN A CONTAINER ONCE AT THE TEMPERATURE HIGHER THAN THAT OF ROOM. (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 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 BLUE COLOR IN HEM.HOWEVER THOSE PHENOMENA DO NOT MEAN MALFUNCTION OR OUT OF ORDER WITH LCD‘S WHICH WILL COME BACK IN THE SPECIFIED OPERATING TEMPER ATURE 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. Sh. KAOHSIUNG HITACHI DATE FEB.10.’98 7B64PS 2711-LMG7520RPFC-4 PAGE 11-3/4 No. ELECTRONICS CO.,LTD. (4) A SLIGHT DEW DEPOSITING ON TERMINALS IS A CAUSE FOR ELECTROCHEMICAL REACTION RESULTING IN TERMINAL OPER 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 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) PLACING IN A DARK PLACE WHERE NEITHER EXPOSURE TO DIRECT SUNLIGHT NOR LIGHT IS, KEEPING TEMPERATURE IN THE RANGE FOR 0°C TO 35°C. (3) STORING WITH NO TOUCH ON POLARIZER SURFACE BY ANYTHING ELSE. (IT IS RECOMMENDED TO STORE THEM AS THEY HAVE BEEN CONTAINED IN THE INNER CONTAINER AT THE TIME OF DELIVERY FOR 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 UP LATER. (2) WHEN ANY LIQUID LEAKED OUT OF A DAMAGED GLASS CELL IN CONTACT WITH YOUR HANDS, PLEASE WASH IT OFF WELL WITH SOAP AND WATER. Sh.
