date : 2005/04/25 ampire co., ltd. 17 9 use precautions 9.1 handling precautions 1) the polarizing plate may break easily so be careful when handling it. do not touch, press or rub it with a hard-material tool like tweezers. 2) do not touch the polarizing plate surface with bare hands so as not to make it dirty. if the surface or other related part of the polarizing plate is dirty, soak a soft cotton cloth or chamois leather in benzine and wipe off with it. do not use chemical liquids such as acetone, toluene and isopropyl alcohol. failure to do so may bring chemical reaction phenomena and deteriorations. 3) remove any spit or water immediately. if it is left for hours, the suffered part may deform or decolorize. 4) if the lcd element breaks and any lc stuff leaks, do not suck or lick it. also if lc stuff is stuck on your skin or clothing, wash thoroughly with soap and water immediately. 9.2 installing precautions 1) the pcb has many ics that may be damaged easily by static electricity. to prevent breaking by static electricity from the human body and clothing, earth the human body properly using the high resistance and discharge static electricity during the operation. in this case, however, the resistance value should be approx. 1m ?
date : 2005/04/25 ampire co., ltd. 18 9.4 operating precautions 1) do not boost the applied drive voltage abnormally. failure to do so may break ics. when applying power voltage, check the electrical features beforehand and be careful. always turn off the power to the lc module controller before removing or inserting the lc module input connector. if the input connector is removed or inserted while the power is turned on, the lc module internal circuit may break. 2) the display response may be late if the operating temperature is under the normal standard, and the display may be out of order if it is above the normal standard. but this is not a failure; this will be restored if it is within the normal standard. 3) the lcd contrast varies depending on the visual angle, ambient temperature, power voltage etc. obtain the optimum contrast by adjusting the lc dive voltage. 4) when carrying out t he test, do not take the module out of the low-temperature space suddenly. failure to do so will cause the module condensing, leading to malfunctions. 5) make certain that each signal noise level is within the standard (l level: 0.2vdd or less and h level: 0.8vdd or more) even if the module has functioned properly. if it is beyond the standard, the module may often malfunction. in addition, always connect the module when making noise level measurements. 6) the cmos ics are incorporated in the module and the pull-up and pull-down function is not adopted for the input so avoid putting the input signal open while the power is on. 7) the characteristic of the semiconductor element changes when it is exposed to light emissions, therefore ics on the lcd may malfunction if they receive light emissions. to prevent these malfunctions, design and assemble ics so that they are shielded from light emissions. 8) crosstalk occurs because of characteristics of the lcd. in general, crosstalk occurs when the regularized display is maintained. also, crosstalk is affected by the lc drive voltage. design the contents of the display, considering crosstalk. 9.5 other 1) do not disassemble or take the lc module into pieces. the lc modules once disassembled or taken into pieces are not the guarantee articles. 2) the residual image may exist if the same display pattern is shown for hours. this residual image, however, disappears when another display pattern is shown or the drive is interrupted and left for a while. but this is not a problem on reliability.
