product specification 25 / 26 lc320wxn ver. 1.0 please pay attention to the followings when you use this tft lcd module. 9-1. mounting precautions (1)you must mount a module using specified mounting holes (details refer to the drawings). (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 (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) it is recommended to avoid the signal cable an d conductive material over the inverter transformer for it can cause the abnormal display and temperatu re rising. (11) 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. 9. precautions www..net www..net
product specification 26 / 26 lc320wxn 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. www..net www..net
