(b) refrain from strong mechanical shock and / or a ny force to the module. in addition to damage, this may cause improper operation or damag e to the module. (c) note that polarizers are very fragile and could be easily damaged. do not press or scratch the surface harder than a hb pencil lead. (d) wipe off water droplets or oil immediately. i f you leave the droplets for a long time, staining and discoloration may occur. (e) if the surface of the polarizer is dirty, cl ean it using some absorbent cotton or soft cloth. (f) the desirable cleaners are water, ipa (isoprop hyl alcohol) or hexane. do not use ketone type materials(ex. acetone), ethy l alcohol, toluene, ethyl acid or methyl chloride. it might permanent damage to the polarize r due to chemical reaction. (g) if the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth . in case of contact with hands, legs or clot hes, it must be washed away thoroughly with soap. (h) protect the module from static , it may cause d amage to the c-mos gate array ic. (i) use fingerstalls with soft gloves in order to k eep display clean during the incoming inspection and assembly process. (j) do not disassemble the module. (k) do not pull or fold the lamp wire. (l) do not adjust the variable resistor which is lo cated on the back side. (m) protection film for polarizer on the module s hall be slowly peeled off just before use so that the electrostatic charge can be minimized. (n) pins of i/f connector shall not be touched dir ectly with bare hands. www.datasheet.co.kr datasheet pdf - http://www..net/
doc.no. rev.no page / 30 ltn140at07-b/w01 27 04-a00-g-100324 samsung secret approval 2. storage (a) do not leave the module in high temperature, an d high humidity for a long time. it is highly recommended to store the module with t emperature from 0 to 35 c and relative humidity of less than 70%. (b) do not store the tft-lcd module in direct sunli ght. (c) the module shall be stored in a dark place. it is prohibited to apply sunlight or fluorescent light during the store. 3. operation (a) do not connect,disconnect the module in the ? power on? condition. (b) power supply should always be turned on/off b y following item 6.3 ? power on/off sequence ?. (c) module has high frequency circuits. sufficien t suppression to the electromagnetic interference shall be done by system manufacturers. grounding and shielding methods may be important to minimize the interference. (d) the standard limited warranty is only applicabl e when the module is used for general notebook applications. if used for purposes other t han as specified, sec is not to be held reliable for the defective operations. it is s trongly recommended to contact sec to find out fitness for a particular purpose. 4. others (a) ultra-violet ray filter is necessary for outdoo r operation. (b) avoid condensation of water. it may result in i mproper operation or disconnection of electrode. (c) do not exceed the absolute maximum rating value . ( the supply voltage variation, input voltage variation, variation in part contents and environmental temperature, so on) otherwise the module may be damaged. (d) if the module displays the same pattern continu ously for a long period of time,it can be the situation when the image ?sticks? to the screen. (e) this module has its circuitry pcb?s on the rear side and should be handled carefully in order not to be stressed. www.datasheet.co.kr datasheet pdf - http://www..net/
