. GENERAL PRECAUTIONS. Handling (a) When the module is assembled, It should be attached to the system firmly using every mounting holes. Be careful not to twist and bend the modules. (b) Refrain from strong mechanical shock and / or any force to the module. In addition to damage, this may cause improper operation or damage to the module and CCFT backlight. (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. If you leave the droplets for a long time, Staining and discoloration may occur. (e) If the surface of the polarizer is dirty, clean it using some absorbent cotton or soft cloth. (f) The desirable cleaners are water, IPA (Isoprophyl Alcohol) or Hexane. Do not use Ketone type materials(ex. Acetone), Ethyl alcohol, Toluene, Ethyl acid or Methyl chloride. It might permanent damage to the polarizer 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 clothes, it must be washed away thoroughly with soap. (h) Protect the module from static, it may cause damage to the CMOS Gate Array IC. (i) Use fingerstalls with soft gloves in order to keep 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 located on the back side. (m) Protection film for polarizer on the module shall be slowly peeled off just before use so that the electrostatic charge can be minimized. (n) Pins of I/F confujitsutor shall not be touched directly with bare hands. Doc.No. LTN56AT4F Rev.No 4AS76 Page 28 / 32
2. STORAGE (a) Do not leave the module in high temperature, and high humidity for a long time. It is highly recommended to store the module with temperature from to 35 C and relative humidity of less than 7%. (b) Do not store the TFTLCD module in direct sunlight. (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 confujitsut,disconfujitsut the module in the Power On condition. (b) Power supply should always be turned on/off by following item 6.3 Power on/off sequence. (c) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall be done by system manufacturers. Grounding and shielding methods may be important to minimize the interference. (d) The cable between the backlight confujitsutor and its inverter power supply shall be a minimized length and be confujitsuted directly. The longer cable between the backlight and the inverter may cause lower luminance of lamp(ccft) and may require higher startup voltage (Vs). (e) The standard limited warranty is only applicable when the module is used for general notebook applications. If used for purposes other than as specified, SEC is not to be held reliable for the defective operations. It is strongly recommended to contact SEC to find out fitness for a particular purpose. ( f ) When you confujitsut a signal cable to LCD, remove an AC adapter by all means. In addition, to confujitsut with keep the correct sequence, not to occur the short by left voltage. 4. OTHERS (a) Ultraviolet ray filter is Fujitsuessary for outdoor operation. (b) Avoid condensation of water. It may result in improper operation or disconfujitsution 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 continuously 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. Doc.No. LTN56AT4F Rev.No 4AS76 Page 29 / 32
