product specification lp154wp4 liquid crystal display 9. precautions please pay attention to the followings 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 uneve n force (ex. twisted stress) is not applied to t h e module. and the case on which a module is mounted should have s ufficient 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 for the cove r case are not desirable because the former generates corrosive gas of attacking the polarizer at high t emperature and the latter causes circuit break by electro-chemical reaction. (6) do not touch, push or rub the exposed polarizers with glas s, 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 c loth.(some cosmetics are detrimental to the polarizer.) (7) when the surface becomes dusty, please wipe gently with a bsorbent cotton or other soft materials like chamois soaks with petroleum benzene . normal - hexane is recommended for cleaning the adhesives ver. 0.2 apr. 07, 2009 25 / 30 chamois soaks with petroleum benzene . normal - hexane is recommended for cleaning the adhesives used to attach front / rear polarizers. do not use acetone, to luene and alcohol because they cause chemical damage to the polarizer. (8) wipe off saliva or water drops as soon as possible. their l ong 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 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 time that brightness is stable after turned on) becomes longer. (4) be careful for condensation at sudden temperature chang e. condensation makes damage to polarizer or 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 suppres sion to the electromagnetic interference shall be done by system manufacturers. grounding and shielding meth ods may be important to minimized the interference. www.datasheet.co.kr datasheet pdf - http://www..net/
product specification lp154wp4 liquid crystal display since a module is composed of electronic circuits, it is not s trong to electrostatic discharge. make certain 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 9-5. storage (1) when the protection film is peeled off, static electricity is generated between the film and polar izer. this should be peeled off slowly and carefully by p eople who are electrically grounded and with well 9-6. handling precautions for protection film 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 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 contac t with any other object. it is recommended that they be stored in the contai ner in which they were shipped. ver. 0.2 apr. 07, 2009 26 / 30 this should be peeled off slowly and carefully by p eople who are electrically grounded and with well ion-blown equipment or in such a condition, etc. (2) the protection film is attached to the polarize r with a small amount of glue. if some stress is ap plied to rub the protection film against the polarizer du ring the time you peel off the film, the glue is ap t to remain on the polarizer. please carefully peel off the protection film witho ut rubbing it against the polarizer. (3) 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 polarizer af ter the protection film is peeled off. (4) you can remove the glue easily. when the glue r emains on the polarizer surface or its vestige is recognized, please wipe them off with absorbent cot ton waste or other soft material like chamois soaked with normal-hexane. www.datasheet.co.kr datasheet pdf - http://www..net/
