(3) refer to i l x v l x2ccfl 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 ma rms until one of the following event occurs. 1. when the brightness becomes 50% or lower than it?s original. 2. when the effective ignition length becomes 80% or lower than it?s 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 voltage above this value should be applied to the lamp for more than 1 second to startup otherwise the lamp may not be turned on. 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 back-light, 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 current 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 back-light 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. 3.2 backlight unit the back-light 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 tables. ta=25 2 c note (1) lamp current is measured with a high frequency current meter as shown below. no 2 pin is v low . lcd module 1 2 a inverter hot : (pink) cold : (white) item symb min typ max unit note lamp current i l (1) startup voltage v s - - v rms (5) ma rms operating life time h r 20,000 hour -- (4) 1000 (25 c) lamp voltage v l frequency f l khz -w power consumption p l -(3), i l =6ma (2) 1300 (0 c) v rms i l =6ma 3.5 6.0 7.0 500 - - 55 70 45 6.0 1 2 a hot : (pink) cold : (white)

(1) the supply voltage of the external system for the 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 before 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. (4) t4 should be measured after the module has been fully discharged between power off and on period. (5) interface signal shall not be kept at high impedance when the power is on. 0 t 1 10 msec 0 t 2 50 msec 0 t 3 50 msec 1sec t 4 power supply v dd 0v 0 v valid power on power off interface signal t 2 t 3 0.9 v dd 0.9 v dd 0.1 v dd t 1 0.1 v dd t 4 power on/off sequence 0.5 v cc t 5 t 6 0.5 v cc power supply for b/l unit 500 msec t 5 100 msec t 6

doc.no. rev.no page LTA104S1-L01 / 22 21 05-000-g-031217 7. general precautions 1. 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 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 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 c-mos 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 connector shall not be touched directly with bare hands.
doc.no. rev.no page LTA104S1-L01 / 22 22 05-000-g-031217 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 0 to 35 cand relative humidity of less than 70%. (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 the module in the ? power on? condition. (b) 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. (c) the cable between the backlight connector and its inverter power supply shall be a minimized length and be connected directly . the longer cable between the backlight and the inverter may cause lower luminance of lamp(ccft) and may require higher startup voltage(vs). 4. others (a) ultra-violet ray filter is necessary for outdoor operation. (b) avoid condensation of water. it may result in improper 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 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.
