(3) refer to i l v l to calculate. (4) life time (hr) of a lamp can be defined as the time in which it continues to operate under the condition ta= 25 2 c and i l = 6.0 ma rms until one of the following event occurs. 1. when the brightness becomes 50% or lower than the original. 2. when the effective ignition length becomes 80% or lower than the original value. (effective ignition length is defined as an area that has less than 70% brightness compared to the brightness in the center point.) (5) the inverter open voltage - this voltage should be measured behind ballast capacitor- has to be larger than the lamp startup voltage. otherwise, backlight may have blinking for a moment after being turned on, or not be turned on. if an inverter has shutdown function, it should keep its open voltage for longer than 1 second even if a lamp connector is open. note) the waveform of the inverter output voltage must be area symmetric and the design of the inverter must have specifications for the modularized lamp. the performance of the backlight, for example life time or brightness, is much influenced by the characteristics of the dc-ac inverter for the lamp. so all the parameters of an inverter should be carefully designed so as not to produce too much leakage cu rrent from high-voltage output of the inverter. when you design or order the inverter, please make sure that a poor lighting caused by the mismatch of the backlight and the inverter(miss lighting, flicker, etc.) never occur. when you confirm it, the module should be operated in the same condition as it is installed in your instrument. note (1) lamp current is measured with a high frequency current meter as shown below. ta= 25 2 c the backlight system is an edge-lighting type with a single ccft ( cold cathode fluorescent tube ). the characteristics of a single lamp are shown in the following table. lcd module 1 2 a inverter hot : ( pink ) cold : ( white ) 25 c, (5) vrms 1120 - - v s startup voltage 0 c, (5) vrms 1345 (4) hour - - 15,000 hr operating life time (3) i l = 6.0ma w 4.6 4.3 - p l power consumption (2) khz 65 60 50 f l frequency i l = 6.0ma vrms - 665 - v l lamp voltage (1) marms 6.5 6.0 3.0 i l lamp current note unit max. typ. min. symbol item - inverter : foxconn / sumida www.datasheet.co.kr datasheet pdf - http://www..net/

(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 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. if you leave t he droplets for a long time, staining and discoloration may occur. (e) if the surface of the polarizer is dirty, clean it using some absorb ent cotton or soft cloth. (f) the desirable cleaners are water, ipa (isoprophyl alcohol) or hexane. do not use ketone type material s(ex. acetone), ethyl alcohol, to luene, ethyl acid or methyl chloride. it might permanent damage to the polarizer d ue to chemical reaction. (g) if the liquid crystal material leaks from the pa nel, 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 ma y cause damage to the c-mos gate array ic. (i) use fingerstalls with soft gl oves in order to keep displa y clean during the incoming inspection and assembly process. (j) do not disasse mble the module. (k) do not pull or fold the lamp wire. (l) do not adjust the variable resi stor 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 connector shall not be touched directly with bare hands. www.datasheet.co.kr datasheet pdf - http://www..net/

(b) do not store the tft-lcd 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 connect,disconnect t he module in the ? power on? condition. (b) power supply should always be tu rned on/off by following item 6.3 ? power on/off sequence ?. (c) module has high frequenc y circuits. sufficient suppre ssion 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 and its invert er power supply shall be a minimized length and be connec ted directly . the longer cable between the back-light and the inverter may cause lo wer luminance of lamp(ccft) and ma y require higher startup voltage (vs). (e) the standard limited warranty is only app licable when the module is used for general notebook applications. if used fo r purposes other t han 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. 4. others (a) ultra-violet ray filter is necessary for outdoor operation. (b) avoid condensation of water. it may result in improper operat ion or disconnection of electrode. (c) do not exceed the absolute maximum rating va lue. ( the supply volt age variation, input voltage variation, variation in part contents and environme ntal temperature, so on) otherwise the module may be damaged. (d) if the module displays the sa me 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. www.datasheet.co.kr datasheet pdf - http://www..net/
