(2) do not touch the polarizing plate surf ace with bare hands so as not to make it dirty. if the surface or other related part of the polariz ing 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, to luene and isopropyl alcohol. failure to do so may bring chemical r eaction 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 stuf f leaks, do not suck or lick it. also if lc stuff is stuck on your skin or cl othing, wash thoroughly with soap and water immediately. 9-2 installing precautions (1) the pcb has many ics that may be da maged easily by static electricity. to prevent breaking by static electricit y from the human body and clothing, earth the human body properly using the high resistance and discharge static electricity during the operation. in th is case, however, the resistance value should be approx. 1m ? and the resistance should be placed near the human body rather than the ground surface. when the indoor space is dry, static electricity may occur easily so be ca reful. we recommend the indoor space should be kept with humidity of 60% or more. when a soldering iron or other similar tool is used for asse mbly, be sure to earth it. (2) when installing the module and ics, do not bend or twist them. failure to do so may crack lc element and cause circuit failure. (3)to protect lc element, especially po larizing plate, use a transparent protective plate (e.g., acrylic plat e, glass etc) for the product case. (4) do not use an adhesive like a both-side adhesive tape to make lcd surface (polarizing plate) and product ca se stick together. failure to do so may cause the polarizing plate to peel off 9-3 storage precautions (1) avoid a high temperature and humidit y area. keep the temperature between 0c and 35c and also the humidity under 60%. (2) choose the dark spaces where the prod uct is not exposed to direct sunlight or fluorescent light. (3) store the products as they are put in the boxes provided fr om us or in the same conditions as we recommend.
date : 2009/01/08 ampire co ., ltd. 18 9-4 operating precautions (1) do not boost the applied drive volt age abnormally. failure to do so may break ics. when applying power voltage, che ck 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 fa ilure; this will be restored if it is within the normal standard. (3) the lcd contrast varies depending on t he visual angle, ambient temperature, power voltage etc. obtain the optimum contrast by adjusting the lc dive voltage. (4) when carrying out the 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 connec t 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 t he input signal open while the power is on. (7) the characteristic of the semiconduc tor element changes when it is exposed to light emissions, therefore ics on t he lcd may malfunction if they receive light emissions. to prevent these ma lfunctions, design and assemble ics so that they are shielded from light emissions. (8) crosstalk occurs because of characteri stics of the lcd. in general, crosstalk occurs when the regularized display is ma intained. 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 ta ke the lc module into pi eces. the lc modules once disassembled or taken into piec es are not the guarantee articles. (2) the residual image may exist if the sa me 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. (3) amipre will provide one year warr antee for all products and three months warrantee for all repairing products.
