i spec 210~ modei. x0. page sharp lc98312 LM8V311 2 1 i operator electrostatic shielding clothes shall be had because it is feared that the static electricity is electrified to human body in case that operator have a insulating garment. 2. equipment there is a possibility that the static electricity is charged to equipment which have a function of peeling or mechanism of friction(ex: conveyer, soldering iron, working table), so the countemxasure countermeasure(electrostaticearth:l x 10? q) should be made. 3. floor floor is a important part to leak static electricity which is generated from human body or equipment. there is a possibility that the static electricity is charged to them without leakage in case of insulating floor, so the countermeasure(electrostatic earth:1 x 10? q) should be made. 4humidity humidity of working room may lower electrostatics generating material?s resistance and have something to prevent electrifying. so, humidity should be kept over 50 % because humidity less than 50 % may increase material?s electrostatic earth resistance and it become easy to electrify. 5.transportationlstorage the measure should be made for storage materials because there is a possibility that the static electricity, which electrify to human body or storage materials like container by friction or perling, cause the dielectric charge. 6. others the laminator is attached on the surface of lcd module to prwent from scratches, fouling and dust. it should be peeled off unhurriedly with using static eliminator. and also, static eliminator should be installed to prevent lcd module from electrifying at assembling line. 8) don?t use any materials which emit gas from epoxy rcsin(amines? hardener) and silicon adhesive agent(dealcohol or deoxym) to prevent change polarizer color owing to gas. 9) since leakage current, which may be caused by routing of ccft cables, etc., may affect the brightness of display, the inverter has to be designed taking the leakage current into consideration. thorough evaluation of the lcd module/inverter built into its host equipment shall be conducted, therefore, to ensure the specified brightness. 10) avoid to expose the module to the direct sun-light, strong ultraviolet light, etc. for a long time. 11) if stored at temperatures under specified storage temperature, the lc may freeze and be deteriorated. if storage temperature exceed the specified rating. the molecular orientation of the lc may change to that of a liquid, and they may not revert to their original state. therefore, the module should be always stored at norm; room temperature. 12) disassembling the lcd module can cause permanent damage and should be strictly avoided.

spec no. model. no. page sharp lc98312 li?dsv3 11 17 data input for column electrodes and chip sekc~ of driver lsi are made as follows: the driver lsi at the left end of the display face is first selected, and the adjacent driver lsi right next side is selected when data of 240 dot (3oxck) is fed. ths process is sequentially continued until data is fed to the driver lsi at the right end of the display face. this process is followed simultaneously both at the top and bottom column drivers lsi?s. thus data input will be made through 8 bit bus line sequentially from the left end of the display face. since this display module contains no refresh ram, it requires the above data and timing pulse inputs even for static display. the timing chart of input signals are shown in fig. 4 and table 7
