31/33 page LTM220M1-L02 model product information product information (a) when the module is assembled, it s hould be attached to the system firmly using all mounting holes. be carefu l not to twist and bend the module. (b) because the inverter uses high volt ages, it should be disconnected from power source before it is assembled or disassembled. (c) refrain from strong mechanical s hock and / or any force to the module. in addition to damage, it may cause improper operation or damage to the module and ccft back light. (d) note that polarizer films are ve ry fragile and could be damaged easily. do not press or scratch the surfac e harder than a hb pencil lead. (e) wipe off water droplets or oil immediat ely. if you leave the droplets for a long time, staining or discoloration may occur. (f) if the surface of the polarizer is dirty, clean it using absorbent cotton or soft cloth. (g) desirable cleaners are water, ip a (isopropyl alcohol) or hexane. do not use ketone type materials (ex. acetone), ethyl alcohol, toluene, ethyl acid or methyl chloride. it might cause perm anent damage to the polarizer due to chemical reaction. (h) if the liquid crystal mate rial leaks from the panel, it should be kept away from the eyes or mouth . in case of c ontact with hands, legs or clothes, it must be washed away with soap thoroughly. (i) protect the module from static, or the cmos gate array ic would be damaged. (j) use finger-stalls with soft gloves in order to keep display clean during the incoming inspection and assembly process. (k) do not disassemble the module. (l) do not pull or fold the lamp wire. (m) do not adjust the variable resistor located on the module. (n) protection film for polarizer on the modul e should be slowly peeled off just before use so that the electrostati c charge can be minimized. (o) pins of i/f connector should not be touched directly with bare hands. 8. general precautions 8.1 handling www.datasheet.co.kr datasheet pdf - http://www..net/
32/33 page LTM220M1-L02 model product information product information 8.2 storage (a) do not leave the module in high temper ature, and high humidity for a long time. it is highly recommended to store the module with temperature from 0 to 35 ? and relative humidity of less than 70%. (b) do not store the tft-lcd m odule in direct sunlight. (c) the module should be stored in a dark place. it is prohibi ted to apply sunlight or fluorescent light in storing. 8.3 operation (a) do not connect or disconnect the m odule in the "power on" condition. (b) power supply should always be turned on/off by the item 6.3 "power on/off sequence" (c) module has high frequency circuits. su fficient suppression to the electromagnetic interference should be done by system manufacturers. grounding and shielding methods may be important to minimize the interference. (d) the cable between the back light connec tor and its inverter power supply should be connected directly with a minimi zed length. a longer cable between the back light and the inverter may caus e lower luminance of lamp(ccft) and may require higher startup voltage(vs). 8.4 operation condition guide (a) the lcd product should be operated under normal conditions. normal condition is defined as below; - temperature : 20 ? 15 ? - humidity : 65 ? 20% - display pattern : continually changing pattern (not stationary) (b) if the product will be used in extreme conditions such as high temperature, humidity, display patterns or operati on time etc.., it is strongly recommended to contact sec for application engineeri ng advice. otherwise, its reliability and function may not be guaranteed. extreme conditions are commonly found at airports, transit stations, banks, stock market, and controlling systems. www.datasheet.co.kr datasheet pdf - http://www..net/
33/33 page LTM220M1-L02 model product information product information 8.5 others (a) ultra-violet ray filter is necessary for outdoor operation. (b) avoid condensation of water. it may resu lt in improper operation or disconnection of electrode. (c) do not exceed the absolute maximum ra ting value. ( supply voltage variation, input voltage variation, variation in part contents and environmental temperature, and so on) otherwise the module may be damaged. (d) if the module keeps displaying the sa me pattern for a long period of time, the image may be "sticked" to the screen. to avoid image sticking, it is recommended to use a screen saver. (e) this module has its circuitry pc b's on the rear side and should be handled carefully in order not to be stressed. (f) please contact sec in advance when you display the same pattern for a long time. www.datasheet.co.kr datasheet pdf - http://www..net/
