"should be included in the instruction manual of the system which may be issued by your organization. for safety warning (1) toshiba matsushita display technology's standard lcd modules have not been customized for operation in extreme environments or for use in applications where performance failures could be life-threatening or otherwise catastrophic. since they must never be installed in aircraft navigation control systems (such as, but not limited to traffic collision system and air traffic indicator), in military defense or w eapons systems, in critical industrial process-control systems (e.g., those involved in the production of nuclear energy), or in critical medical device or patient life-support systems. (2) disconnect power supply before handling lcd module. do not touch the parts inside lcd module and the fluorescent lamp's (hereinafter called "fl") connector or cable in order to prevent electric shock, because high voltage is supplied to these parts from the inverter unit while power supply is turned on. (3) make sure to insert the module fl connector to the inverter connector in correct position. do not insert in irregular position. if incorrect, this may cause smoke or burn of electrical parts by high voltage of fl circuit. if there is a possibility that the connector has been inserted incorrectly, please re-insert the connector only after you confirm the module and fl power is completely off. when disconnecting connector, do not pull on the cable. do not use the mating fl connector which toshiba matsushita display technology does not specify. otherwise, toshiba matsushita display technology shall not be liable for any damages caused by the connector. caution (1) do not disassemble or modify the module. sensitive parts inside lcd module may be damaged, and dusts or scratches may mar the displays. toshiba matsushita display technology does not warrant the modules, if customer disassembled or modified them. ? (2) do not ingest liquid crystal material, do not inhale th is material, and do not permit this material to contact the skin, if glass of lcd panel is broken. if liquid crystal material contacts the skin, mouth or clothing, take the following actions immediately. in case contact to the eye or mouth, rinse with large amount of running water for more than 15 minutes. in case contact to the skin or clothing, wipe it off immediately and wash with soap and large amount of running water for more than 15 minutes. the skin or closing may be damaged if liquid crystal material is left adhered. in case ingestion, rinse out the mouth well with water. after spewing up by drinking large amount of water, get medical treatment. ? (3) be careful with chips of glass that may cause in juring fingers or skin, when the glass is broken. since fl is also made of glass, when fl is built in, handle it with due caution a well. (4) be careful with handling the metal flame (bezel) of a module. even though burr disposal treatment is performed, it may cause injuring. be careful with edges of glass parts and touch panel identically. for designing the system, give special consideration that the wiring and parts do not touch those edges. (5) do not exceed the absolute maximum rating values under the worst probable conditions caused by the supply voltage variation, input voltage variation, variation in parts' constants, ambient temperature, etc., otherwise lcd module may be damaged. www..net www..net

(the lcd panel should be used within ?the recommended operation conditions?.) the performance and quality of the lcd panel are warranted only when the lcd panel is used within ?the recommended operation conditions?. toshiba matsushita display technology never warrants the performance and quality of the lcdpanel when you use the lcd panel over ?the recommended operation conditions?, although within ?the absolute maximum rating?. to use the lcd panel over ?the recommended operation condi tions? may have bad influence on the characteristics and reliability of the lcd panel and may shorten the life of the lcd panel. therefore, when designing the whole set, not to be over ?the recommended operation conditions?, you should fully take care of supply voltage change, characteristic of c onnection parts, serge of input-and-output line , and surrounding temperature. (7) suitable protection circuit should be applied for each system design. do not modify the fuse used in the module. it may cause overheat and/or burning if dusts or metal particles are on the pcbs in the lcd module. (8) be sure that power supply output from the system shou ld be limited to smaller values than listed shown below. (for example quick arcing fuse with listed ratings can be used.) it is because this lcd module explained in this specification has a current limiter, with such function at power input line(s). but it may be some possibility of overheat and/or burning of lcd module and its peripheral devices before current limiter of the module when open-short test of the module is performed by using power supply higher than following recommended value. power supply recommended maximum output current of power supply recommended fuse rating (in case of using fuse for current limiter) built-in fuse rating (for reference) v dd 4.0 a 0.5-3.0 a 1.25 a (9) always comply with all applicable environmental regulations, when disposing of lcd. (10) when fl becomes extremely dark and its color changes from white to pink, stop the use of the module immediately. fl, at the end of its life with its discharge color turns into pink as the characteristics of fl, may adversely affect the module a t the end part of fl due to temperature raising caused by depl etion of the mercury which is contained in fl tube, or may have a possibility of breakage. for designing the system (1) toshiba matsushita display technology always endeavor to maintain sufficient quality of the lcd panel in process of designing and manufacturing, however, to avoid causing extended damages such as accidents resulting in injury or death, fire accidents, or social damages if the lcd panel fails, please adopt safe design as a whole set, by adoptingredundant design , taking measure in set design to prevent fire-spreading, over-current, or incorrect operation, etc. (2) lcd module should be assembled to the system by using all mounting holes specified in this specification and with the specified screws. in addition, some modules may not be necessary to use all the mounting holes. make comprehensive judgments on the entire system. www..net www..net

(4) do not give high voltage to "low voltage" side of the fl. for example, do not use a floating inverter which gives high voltage to "low voltage" side. it may cause insufficient brightness or unstable operation of fl, and smoke or burn of the parts. (5) make sure to connect correctly high-voltage wire and low-voltage wire between fl tube and inverter unit. (6) input fl starting voltage( v sfl ) should not be less than two second. if it were less than two second, it may cause unstable operation of fl. inverter should be design to stop output when the inverter is no-load to fl tubes (due to breakage of fl, etc.) to prevent high-voltage generation. when high voltage is applied to fl continuously without normal operation of fl (due to output leakage within fl wiring circuit, etc.) it may cause smoke or burn. to prevent excess current, design the inverter with a protection circuit such as a current limiter (excess current dete ction) to stop inverter output. please adjust inverter circuit parameters, such as capaci tor, resistor, to assure the display quality is maintained. there is a possibility that flicker is observed by the interference of lcd operating signal timing and fl driving condition (especially driving frequency). (7) in case of severe environmental condition like outdoor usage, a proper transparent protective cover(lens) over lcd module is recommended to apply in order to prevent scratches, and invasion of dust, water, etc., from the system's window onto lcd module. ultra-violet ray cut filter is recommended to apply onto lcd module for outdoor operation. strong ultra-violet ray may cause damage the panel. however, in that case, transmittance-luminance will decrease. careful selection of material is required. (8) design the system not to display same pattern for a long time in order to prevent image sticking on the panel. note that incorrect sequence of power supplies and input signals may cause the sticking on the panel, too. (9) some plastic materials and shock absorbing materials (rubber) used in the system may generate gases that may cause the deterioration of the polarizer laminated on lcd?s panel or internal parts of the module. prior confirmation is required. (10) some materials used for packaging (for which sulfuric acid is used in the recycling process) generate gases that may cause the deterioration of the polarizer laminated on lcd?s panel or internal parts of the module. prior confirmation is required. for installation in assembly (1) the c-mos lsis used in lcd module are very sensitive to esd (electro-static discharge). ambient humidity of working area is recommended to be higher than 50%(rh). person handling lcd modules should be grounded with wrist band. tools like soldering iron and screw driver, and working benches should be grounded. the grounding should be done through a resistor of 0.5-1m ? in order to prevent spark of esd. (2) when remove protection film from lcd panel, peer off the film slowly (more than three seconds) from the edge of the panel, using a soft-pointed tweezers covered by teflon or adherent tape. www..net www..net

(4) when lcd panel becomes dirty, wipe off the panel surface softly with absorbent cotton or another soft cloth. if necessary, breathe upon the panel surface and then wipe off immediately and softly again. if the dirt can not be wiped off, absorbent cotton wetted a little with normal-hexane or petroleum benzine can be used for wiping the panel. be careful not to spill this solvent into the inside of lcd module. driver ics and pcb area used inside lcd module may be damaged by the solvent. ? (5) avoid the condensation of water wipe off a spot or spots of water of mist and chemicals of mist on lcd panel softly with absorbent cotton or another cloth as soon as possible if happened, otherwise discoloration or stain may be caused. if water invade into lcd module, it may cause lcd module damages. ? (6) do not expose lcd module to the gas (which is not normally contained in the atmosphere), it may cause mis-operation or defects. ? (7) do not apply mechanical forces. do not bend or twist lcd module even momentary when lcd module is installed an enclosure of the system. bending or twisting lcd module may cause its damages. make sure to design the enclosure that bending/twisting forces are not applied to lcd module when it is installed in the system. refrain from strong mechanical shock like dropping from the working bench or knocking against hard object. these may cause glass of the panel crack, damage of fl or other miss-operation. ? (8) refrain from excessive force like pushing the surface of lcd panel. this may cause damage of the panel or electrical parts on pcb. ? (9) do not put heavy object such as tools, books, etc., and do not pile up lcd modules. be careful not to touch surface of the polarizer laminated to the panel with any hard and sharp object. the polarizer is so soft that it can easily scratched, even the protect film covers it. (10) when inserting or disconnecting the connectors to lcd module, be sure not to apply force against pcb, nor connecting cables, otherwise internal connection of pcb and tab drivers may be damaged. do not fasten screws while putting cables like those for interface or fl between lcd module and the enclosure. make sure to insert the module fl connector to the inverter connector in correct position. if incorrect, this may cause smoke or burn of electrical parts by high voltage of fl circuit. (11) be careful not to pull the fl cables of the backlight in order to avoid mechanical damage in fl lamp and soldering area. be careful not to pull or not to hurt the fpc (flexible printed circuit) cables. (12) power supplies should always be turned off in assembling process. do not connect or disconnect the power cables and connec tors with power applied to lcd module. this may cause damage of module circuit. the signal should be applied after power are turned on. and the signal should be removed before power supplies are turned off. (refer to "for designing the system"(2).) ? (13) in case of lcd long period operation, discoloration of light guide or optical sheet will be happened due to ultra violet and heat from ccfl. as the result, there is possibility to have out of specification for the optical characteristic as ?5.2?. but this is not irregular phenomena. moreover, ccfl also has the characteristic of color shift by long period operation. www..net www..net
