(2) you should consider the mounting structure so that uneven force (ex. twisted stress) is not applied to the module. and the case on which a module is mounted should have sufficient strength so that external force is not transmitted directly to the module. (3) please attach the surface transparent protective plat e to the surface in order to protect the polarizer. 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 for the cover case are not desirable 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 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 gently with absorbent cotton or other soft materials like 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 possib le. 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 (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 temperature, 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. condensation makes damage to polarizer or electrical contacted parts. and after fadi ng condensation, smear or spot will occur. (5) when fixed patterns are displayed for a l ong time, remnant image is likely to occur. (6) 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 minimized the interference. (7) please do not give any mechanical and/or acoustical impact to lcm. otherwise, lcm can?t be operated 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 deal lcm a fatal blow) (9) please do not set lcd on its edge. 9. precautions product specification 28 / 30 LC420WU1 liquid crystal display ver. 1.0 july. 22, 2005 since a module is composed of electronic circuits, it is not strong to electrostatic discharge. make certain that treatment persons are connected to ground through wris t band 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 precautions are necessary. (1) store them in a dark place. do not expose the module to sunlight 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 which they were shipped. 9-5. storage 9-6. handling precautions for protection film (1) the protection film is attached to the bezel with a small masking tape . when the protection film is peeled off, static el ectricity is generated betw een the film and polarizer. this should be peeled off slowly and carefully by people who are electrically grounded and with well ion- blown equipment or in such a condition, etc. (2) when the module with protection film attached is st ored for a long time, sometimes there remains a very small amount of glue still on the bezel af ter the protection film is peeled off. (3) you can remove the glue easily. when the glue remains on the bezel surface or its vestige is recognized, please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normal- hexane. appendix a : inverter input voltage protection circuit the cas is only defined as spec-i n parameters, so lpl and philips agr ee to make an appendix for inverter input voltage circuit application in terms of LC420WU1-sl01 1.input voltage protection circuit definition input voltage protection circuit perceive abnormal input voltage coming at the master & slave inverter. in case the inverter input voltage level is under 19.v or over 27.5v, this circuit operates for preventing inverter?s abnormal operation. if inverter input voltage come back normal conditi on, this protection circuit will be reset and inverter works properly. 2. input voltage protection circuit contents the original purpose of inverter input voltage protection circuit is only for preventing inverter?s damage. please don?t regard this circuit and voltage level as the parameters which should be controlled. 1) high voltage protection : over 27.5v 2) low voltage protection : under 19v 3. agreement the protection circuit can?t be eliminated without both of lpl and philips agreement < 7 > < 7 > p o 0 ' ' 3 f t f u 0 / 0 ' ' 3 f t f u 0 / 0 ' ' 3 f t f u 0 / 0 ' ' 29 / 30 ver. 1.0 july. 21, 2005 appendix b : black level and black uniformity a : h / 4 mm b : v / 4 mm h : 697.685 mm v : 392.256 mm @ h,v : active area h a v b y ? t it is not available to be specified bl ack level and black uniformity on the spec at this moment. so lpl will get more actual data for the future production(LC420WU1-sl01). 1. black level : surface luminance of black (l black ) is the luminance value at center 1-point. 2. black uniformity the variation of surface luminance of black , black is defined as : black = maximum(l on1 ,l on2 , l on3 , l on4 , l on5 ) / minimum(l on1 ,l on2 , l on3 , l on4 , l on5 ) 3. sampling size : regular rv event test quantity ( 5 pcs ) 4. measurement method : follow same rule as optical characteristics measurement. 5. measurement location: refer to below. 6. current status below is actual data of production on rv (4 jul 2005 ~ 5 jul 2005 ). this is only useful for reference. 1) light leakage & stitch limit sample : # 177 2) touch limit sample : #148 no. luminance black level 1 639 606 623 619 647 2 0.75 0.76 0.78 0.75 3 4 50.78 7. plan to review black level and black uniformity lpl will continue to monitor the black level and unif ormity. both lpl and philips will review black level as well as black uniformity together. this spec will be discussed sooner or later.
