[operating condition: continuous operating at ta = 25 2 ] 6. the performance of the lamp in lcd panel, for example life time or brightness, is extremely influenced by the characteristics of balanced board and i/p board. all the parameters should be carefully designed as not to produce too much leakage current from high-voltage output. while you design or order the balance board, please make sure unwanted lighting caused by the mismatch of the lamp and the balanced board (no lighting, flicker, etc) never occurs. after confirmation, the lcd panel should be operated in the same condition as installed in your instrument 7. do not attach a conducting tape to lamp connecting wire. if the lamp wire attach to conducting tape, tft-lcd module have a low luminance and the inverter has abnormal action because leakage current occurs between lamp wire and conducting tape. 8. the relative humidity must not exceed 80% non-condensing at temperatures of 40 or less. at temperatures greater than 40 , the wet bulb temperature must not exceed 39 . when operate at low temperatures, the brightness of ccfl will drop and the life time of ccfl will be reduced.

(3) please attach the surface transparent protective plate 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 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 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 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 suppression to the electromagnetic interference shall be done by system manufacturers. grounding and shielding methods may be important to minimize the interface. (7) the device listed in the product specification sheets was designed and manufactured for tv application.

(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. 9-6 handling precautions for protection film for take module out carton (1) 52 module is heavy and not easy handle. please move out carton with assistant equipment and do not twist the module. 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 electricity is generated between 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 stored for a long time, sometimes there remains a very small amount of flue still on the bezel after the protection 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 soft material like chamois soaked with normal-hexane.
