electrical characteristics of inverter are bas ed on high-high driving type. the performance of the lamps in lcm, for example li fe time or brightness, is extremely influenced by the characteristics of the dc-ac inverter. so, all the parameters of an inverter should be carefully designed so as not to produce too much leakage curr ent from high-voltage output of the inverter. when you design or order the inverter, please make sure unwanted lighting caused by the mismatch of the lamp and the inverter (no lighting, flicker, etc) has never been occurred. when you confirm it, the lcdC assembly should be operated in the same con dition as installed in your instrument. do not attach a conductive tape to lamp connecting wire. if you attach conductive tape to the lamp wire, not only luminance level can be lower than typical one but also inverter operate abnormally on account of leakage current which is generated between lamp wir e and conductive tape. 1. specified values are defined for a backlight ass embly.( ibl : 18 lamp, 7.5ma/lamp) 2. operating voltage is measured at 25 2 c(after 2hr.aging). the variance range for operati ng voltage is 10%. 3. the established starting voltage [ v s ] should be applied to the lamps for more than stri king time (s time ) for start-up. inverter open voltage must be more th an established starting voltage. otherwise, the lamp s may not be turned on. the used lamp current is typical value. 9 % 100 20 pwm duty burst dimming duty 1000 - - v s 25 9 hz 182 98 1/t burst dimming frequency 0 1 ma rms 140 135 130 i bl 3 sec 1.5 - - s time striking

cause beat on the display. therefore, lamp frequenc y shall be as away possible from the horizontal synchronous frequency and its harmonics range in or der to prevent interference. 5. the brightness of the lamp after lighted for 5mi nutes is defined as 100%. t s is the time required for the brightness of the cent er of the lamp to be not less than 95% at typical c urrent. the screen of lcd module may be partially dark by t he time the brightness of lamp is stable after tur n on. 6. maximum level of power consumption is measured a t initial turn on. typical level of power consumption is measured afte r 2hrs aging at 25 2 c. 7. the life time is determined as the time at which brightness of the lamp is 50% compared to that of initial value at the typical lamp current on condition of c ontinuous operating at 25 2 c, based on duty 100%. 8.the output of the inverter must have symmetrical( negative and positive) voltage and current waveform (unsymmetrical ratio is less than 10%). please do n ot use the inverter which has not only unsymmetrica l voltage and current but also spike wave. requirements for a system inverter design, which is intended to achieve better display performance, power efficiency and more reliable lamp characteris tics. it can help increase the lamp lifetime and reduce l eakage current. a. the asymmetry rate of the inverter waveform shou ld be less than 10%. b. the distortion rate of the waveform should be wi thin 2 10%. * inverter output waveform had better be more simil ar to ideal sine wave. product specification 9 /37 LC420WUF ver. 1.0 9. the reference method of burst dimming duty rati o. it is recommended to use synchronous v-sync frequen cy for prevent waterfall(vsync x 1 =burst frequency) we recommend not to be much different between pwm duty and iout duty . minimum pwm duty ratio should be defined based on t he minimum luminance. dimming current output rising and falling time may produce humming and inverter trans sound noise. burst dimming duty should be 100% for 1second after turn on equipment oscilloscope :tds3054b(tektronix) current probe : p6022 ac (tektronix) high voltage probe: p5100(tektronix) 11. the operating current must be measured as near as backlight assembly input. 12. the operating current unbalance between left an d right must be under typ 10% . 10. the cable between the backlight connector and i ts inverter power supply should be connected direct ly with a minimized length. the longer cable between t he backlight and the inverter may cause the lower luminance of lamp and may require more higher starti ng voltage ( vs ). pwm output of inverter to lamp a i-out 90% point a point b pwm duty={ a/t } * 100 point a : rising time 90% of iout point . point b : falling starting

(2) you should consider the mounting structure so t hat uneven force (ex. twisted stress) is not applie d to the module. and the case on which a module is mounted s hould have sufficient strength so that external force is not transmitted directly to the module. (3) please attach the surface transparent protectiv e plate to the surface in order to protect the pola rizer. transparent protective plate should have sufficient strength in order to the resist external force. (4) you should adopt radiation structure to satisfy the temperature specification. (5) acetic acid type and chlorine type materials fo r the cover case are not desirable because the form er generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit b reak by electro-chemical reaction. (6) do not touch, push or rub the exposed polarizer s with glass, tweezers or anything harder than hb pencil lead. and please do not rub with dust clothe s with chemical treatment. do not touch the surface of polarizer for bare hand or greasy cloth.(some cosmetics are detrimental to the polarizer.) (7) when the surface becomes dusty, please wipe gen tly with absorbent cotton or other soft materials l ike chamois soaks with petroleum benzine. normal-hexane is recommended for cleaning the adhesives used to attach front / rear polarizers. do not use acetone, toluene and alcohol because they cause chemical damage to the polarizer. (8) wipe off saliva or water drops as soon as possi ble. their long time contact with polarizer causes deformations and color fading. (9) do not open the case because inside circuits do not have sufficient strength. 9-2. operating precautions 9. precautions (1) the spike noise causes the mis-operation of cir cuits. it should be lower than following voltage : v= 200mv(over and under shoot voltage) (2) response time depends on the temperature.(in lo wer temperature, it becomes longer.) (3) brightness depends on the temperature. (in lowe r temperature, it becomes lower.) and in lower temperature, response time(required ti me that brightness is stable after turned on) becom es longer. (4) be careful for condensation at sudden temperatu re change. condensation makes damage to polarizer o r electrical contacted parts. and after fading conden sation, smear or spot will occur. (5) when fixed patterns are displayed for a long ti me, remnant image is likely to occur. (6) module has high frequency circuits. sufficient suppression to the electromagnetic interference sha ll be done by system manufacturers. grounding and shieldi ng methods may be important to minimized the interference. (7) please do not give any mechanical and/or acoust ical impact to lcm. otherwise, lcm cant be operate d its full characteristics perfectly. (8) a screw which is fastened up the steels should be a machine screw. (if not, it causes metallic foreign material and de al lcm a fatal blow) (9) please do not set lcd on its edge. (10) partial darkness may happen during 3~5 minutes when lcm is operated initially in condition that luminance is under 40% at low temperature (under 5 ). this phenomenon which disappears naturally after 3~5 minutes is not a problem about reliabili ty but lcd characteristic. product specification 28 /37 LC420WUF ver. 1.0 since a module is composed of electronic circuits, it is not strong to electrostatic discharge. make c ertain that treatment persons are connected to ground through w rist band etc. and dont touch interface pin direct ly. 9-3. electrostatic discharge control strong light exposure causes degradation of polariz er and color filter. 9-4. precautions for strong light exposure when storing modules as spares for a long time, the following precautions are necessary. (1) store them in a dark place. do not expose the m odule to sunlight or fluorescent light. keep the te mperature between 5 c and 35 c at normal humidity. (2) the polarizer surface should not come in contac t with any other object. it is recommended that they be stored in the contai ner in which they were shipped. 9-5. storage 9-6. handling precautions for protection film (1) the protection film is attached to the bezel wi th a small masking tape . when the protection film is peeled off, static elec tricity is generated between the film and polarizer . this should be peeled off slowly and carefully by p eople who are electrically grounded and with well i on- blown equipment or in such a condition, etc. (2) when the module with protection film attached i s stored for a long time, sometimes there remains a very small amount of glue still on the bezel after the p rotection film is peeled off. (3) you can remove the glue easily. when the glue r emains on the bezel surface or its vestige is recog nized, please wipe them off with absorbent cotton waste or other soft material like chamois soaked with norma l- hexane. product specification 29 /37 LC420WUF ver. 1.0 # appendix-i-1 required signal assignment for flat link (thine : t hc63lvd103) transmitter(pin7=l) notes :1. the lcd module uses a 100 ohm[ ] resistor between positive and negative lines of e ach receiver input. 2. refer to lvds transmitter data sheet for detail descriptions.
