product specification 33 / 34 lm240wu4 liquid crystal display ver. 1.0 apr. 21 . 2008 9. precautions please pay attention to the followin gs 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 force (ex. twisted stress) is not applied to the module. and the case on which a module is mounted sh ould have sufficient strength so that external force is not transmitted directly to the module. (3) please attach the surface transparent protective pl ate 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 polarize rs 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 gent ly with absorbent cotton or other soft materials like chamois soaks with petroleum benzene. normal-hex ane is recommended for cleaning the adhesives used to attach front / rear polarizers. do not us e 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 circ uits. it should be lower than following voltage : v= 200mv(over and under shoot voltage) (2) response time depends on the temperatur e.(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 fading condensation, smear or spot will occur. (5) when fixed patterns are displayed for a long time, remnant image is likely to occur. (6) module has high frequency circuits. sufficient supp ression 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 acoustic al 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. www..net www..net
product specification 34 / 34 lm240wu4 liquid crystal display ver. 1.0 apr. 21 . 2008 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 degrad ation 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 between the film and polarizer. this should be peeled off slowly and carefully by pe ople 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, sometime s there remains a very small amount of glue still on the bezel after the protection film is peeled off. (3) you can remove the glue easily. when the glue remain s on the bezel surface or its vestige is recognized, please wipe them off with absorbent cotton waste or ot her soft material like chamois soaked with normal- hexane. www..net www..net
