(inverter open voltage must be more than lamp starting voltage.) otherwise, the lamps may not be turned on. the used lamp current is the lamp typical current. 4. lamp frequency may produce interface with horizontal synchron ous frequency and as a result this may cause beat on the display. therefore lamp freq uency shall be as away possible from the horizontal synchronous frequency and from its harmo nics in order to prevent interference. 5. let ? s define the brightness of the lamp after being lighted for 5 mi nutes as 100%. t s is the time required for the brightness of the center of the la mp to be not less than 95%. 6. the lamp power consumption shown above does not include loss of external inverter. the used lamp current is the lamp typical current. (p bl = v bl x i bl x n lamp ) 7. the life 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 conditio n of continuous operating at 25 ? 2 ?? c.
product specification 8 / 28 LM190E02 liquid crystal display ver 0.0 jan. 07, 2004 8. the output of the inverter must have symmetrical(negative and po sitive) voltage waveform and symmetrical current waveform (unsymmetrical ratio is less than 10%). please do not use the inverter which has unsymmetrical v oltage and unsymmetrical current and spike wave. requirements for a system inverter design, which is intended to have a better display performance, a better power effic iency and a more reliable lamp, are following.it shall help increase the lamp lifetime a nd reduce leakage current. a. the asymmetry rate of the inverter waveform should b e less than 10%. b. the distortion rate of the waveform should be within ?? 2 ?? 10%. * inverter output waveform had better be more similar to ideal sine wave. 9. the inverter which is combined with this lcm, is highly r ecommended to connect coupling(ballast) condenser at the high voltage output s ide. when you use the inverter which has not coupling(ballast) condenser, it may cause abnormal lamp lighting because of biased mercury as time goes. 10.in case of edgy type back light with over 4 parallel lamp s, input current and voltage wave form should be synchronized i p i - p * asymmetry rate: | i p ? i ? p | / i rms x 100% * distortion rate i p (or i ? p ) / i rms

product specification 27 / 28 LM190E02 liquid crystal display ver 0.0 jan. 07, 2004 9. precautions please pay attention to the following when you use this tft lcd module. 9 - 1. mounting precautions (1) you must mount a module using holes arranged in four corners or four sides. (2) you should consider the mounting structure so that uneven fo rce(ex. twisted stress) is not applied to the module. and the case on which a module is mounted should have sufficien t strength so that external force is not transmitted directly to the module. (3) please attach a transparent protective plate to the surface in order to protect the polarizer . transparent protective plate should have sufficient strengt h in order to the resist external force. (4) you should adopt radiation structure to satisfy the temperat ure specification. (5) acetic acid type and chlorine type materials for the cover c ase are not describe because the former generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break by electro - chemical reaction. (6) do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than hb pencil lead. and please do not rub with dust clothes with c hemical treatment. do not touch the surface of polarizer for bare hand or greasy cloth.(some cosmetics are determined to the polarizer .) (7) when the surface becomes dusty, please wipe gently with abso rbent cotton or other soft materials like chamois soaks with petroleum benzene. 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 possible. their lo ng time contact with polarizer causes deformations and color fading. (9) do not open the case because inside circuits do not have suf ficient strength. 9 - 2. operating precautions (1) the spike noise causes the mis - operation of circuits. it should be lower than following voltage : v= ?? 200mv(over and under shoot voltage) (2) response time depends on the temperature.(in lower temperatu re, it becomes longer.) (3) brightness depends on the temperature. (in lower temperature , it becomes lower.) and in lower temperature, response time(required time that brightness is stable after turned on) becomes longer. (4) be careful for condensation at sudden temperature change. co ndensation makes damage to polarizer or electrical contacted parts. and after fading condensation, sm ear or spot will occur. (5) when fixed patterns are displayed for a long time, remnant i mage is likely to occur. (6) module has high frequency circuits. sufficient suppression t o the electromagnetic interference shall be done by system manufacturers. grounding and shield ing methods may be important to minimized the interference. (7) please do not give any mechanical and/or acoustical impact t o lcm. otherwise, lcm can not be operated its full characteristics perfectly. (8) a screw which is fastened up the steels should be a machine screw (if not, it causes metal foreign material and deal lcm a fatal blow) (9) please do not set lcd on its edge.
product specification 28 / 28 LM190E02 liquid crystal display ver 0.0 jan. 07, 2004 since a module is composed of electronic circuits, it is not str ong to electrostatic discharge. make certain that treatment persons are connected to ground through wrist ban d etc. and don ? t touch interface pin directly. 9 - 3. electrostatic discharge control strong light exposure causes degradation of polarizer and color filter. 9 - 4. precautions for strong light exposure when storing modules as spares for a long time, the following pr ecautions are necessary. (1) store them in a dark place. do not expose the module to sunl ight or fluorescent light. keep the temperature between 5 ?? c and 35 ?? c at normal humidity. (2) the polarizer surface should not come in contact with any other object. it is recommended that they be stored in the container in w hich they were shipped. 9 - 5. storage (1) the protection film is attached to the bezel with a small maskin g tape. when the protection film is peeled off, static electricity is generated between the film and polarizer . this should be peeled off slowly and carefully by people who ar e electrically grounded and with well ion - blown equipment or in such a condition, etc. (2) when the module with protection film attached is stored for a long time, sometimes there remains a very small amount of glue still on the bezel after the prot ection film is peeled off. (3) you can remove the glue easily. when the glue remains on the bezel or its vestige is recognized, please wipe them off with absorbent cotton waste or other s oft material like chamois soaked with normal - hexane. 9 - 6. handling precautions for protection film
