LP141X3 liquid crystal display product specification revision ver 1.0 05/ february /1998 page 15 /19 11. handling precautions please pay attention to the followings when you use this tft/lcd module with back-light unit. 11.1.mounting preacaution 1)you must mount module using mounting holes arranged in 4 corners. be sure to turn off the power when connecting or disconnecting the circuit. 2) note that the polarizers are easily damaged. pay attention not to scratch or press this surface with any hard object. 3) when the lcd surface become dirty, please wipe it off with a soft material. (ie.cotton ball) 4) protect the module from the esd as it may damage the electronic circuit (c-mos). make certain that treatment person ? s body are grounded thru wrist bend. 5) do not disassemble the module and be careful not to incur a mechanical shock that might occur during installation. it may cause permanent damage. 6) do not leave the module in high temperatures, particularly in areas of high humidity for a long time.
lg electronics, inc. LP141X3 liquid crystal display product specification revision ver 1.0 05/ february /1998 page 16 /19 7) the module not be expose to the direct sunlight. 8) avoid contact with water as it may a short circuit within the module. 11.2 operating precaution 1) the spike noise causes the mis-operation of circuits. be lower the spike noise as follows : vdd=+- 200mv, v1=+- 200mv( over and under shoot voltage.) 2) response time depends on the temperature. (in lower temperature, it becomes longer.) 3) brightness depends on the temperature. (in lower temperature, it becomes lower.) and in lower temperature, response time (required time that brightness is stable after turn on)becomes longer. 4) be careful for condensation at suddern temperature change. condensation make damage to polarizer or electrical contact part. and after fading condensation, smear or spot will occur. 5) when fixed pattern are displayed at long times, remnant image is likely to occur. 6) module has high frequency circuit. if you need to shield the electromagnetic noise. please do in yours. 7) when back-light unit is operating, it sounds. if you need to shield the noise, please do in yours. 11.3 electrostatic discharge control since module is composed with electronic circuit, it is not strong to electrostatic discharge. make certain that treatment persons are connected to ground through list band etc.. and don ? t touch i/f pin directly. 11.4 precaution for strong light exposure. strong light exposure causes degradation of polarizer and color filter.
lg electronics, inc. LP141X3 liquid crystal display product specification revision ver 1.0 05/ february /1998 page 17 /19 11.5 storage when storing module as spares for long time, the following precautions are necessary. 1) store them in a dark place : do not expose then to sunlight or fluorescent light. keep the temperature between 5 and 35 at normal humidity. 2) the polarizer surface should not come in contact with any other object. it is recommended that they be stored in the container in which they were shipped. 11.6 handling precautions for protection film 1) when the protection film is pealed off, static electricity is generated between the film and the polarizer. this film should be pealed off slowly and carefully by people who are electrically grounded and with well ion- blown equipment or in such a condition. etc. 2) the protection film is attached the polarizer with a small amount of glue.if some stress is applied to rub the protection film against the polarizer during the time you peal off the film, the glue is apt to remain more on the polarizer. so please carefully peal off the protection film without rubbing it against the polarizer. 3) when the module with protection film attached is stored for long time, sometimes there remains a very small amount of glue still on the polarizer after the protaction film is pealed off. please refrain from storing the module at the high temperature and high humidity for glue is apt to remain in these condition. 4) the glue may be taken for the modules failure, but you can remove the giue easily. when the glue remains on the polarizer surface or its vestige is recognized, please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normal-hexane. 11.7 safety 1) if module is broken, be careful to handle not to injure. (tft/lcd and lamp are made of glass) please wash hands sufficiently when you touch the liquid crystal coming out from broken lcds. 2) as it is possible for pcb or other electronic parts of module to small to smoke and to take fire becauseof the short circuit. please design the circuit of your instrument not to flow the electric current to tft/lcd module more than 500ma. (by apply the fuse for example) 3) as back-light unit has high voltage circuit internal, do not open the case and do not insert foreign materials in the case.
