(1) the supply voltage of the external system for t he module input should be the same as the definition of v dd . (2) apply the lamp voltage within the lcd operation range. when the back-light turns on before the lcd operation or the lcd turns off befor e the back-light turns off, the display may momentarily become white. (3) in case of v dd = off level, please keep the level of input signals on the low or keep a high impedance.

(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 and ccft back-light. (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.

(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 cable between the back-light connector an d its inverter power supply shall be a minimized length and be connected directly . the l onger cable between the back-light and the inverter may cause lower luminance of lamp( ccft) and may require higher startup voltage (vs). (e) 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 pcbs on the rear side and should be handled carefully in order not to be stressed.
