spec no. lcy - 12t09 602c model no. ls027b4d h 01 page 2 [for handling and system design] (1) handle with care as glass is used in this lcd panel. dropping or contact against h ard object may cause cracks or chips. (2) be careful to handle this lcd panel in order to avoid injury yourself by panel`s edge as this panel is made of glass and might be a sharp edge. ( 3 ) do not scratch the surface of the polarizer film as it is easily damaged. ( 4 ) water droplets on the polarizer film must be wiped off immediately as they may cause color changes, or other defects if remained for a long time. (5)do not leav e the lcd panel in direct sun or under ultraviolet ray. ( 6 ) to clean lcd panel surface, wipe clean with absorbent cotton or soft cloth. if further cleaning is needed, use ipa (isopropyl alcohol) and wipe clean lightly on surface only. do not use organic solvents as it may damage the lcd panel terminal area which uses organic material. also , do not directly touch with finger. w hen the terminals cleaning are needed, those should be wiped by a soft cloth or a cotton swab without directly touching by hand. ( 7 ) do not expose gate driver, etc. on the panel (circuit area outside panel display area ) to light as it may not operate properly. design that shields gate driver, etc. from light is required when mounting the lcd module. (8) to avoid circuit failure, do not touch panel terminal area. ( 9 ) support for the lcd panel should be carefully designe d to avoid stress that exceeds specification on glass surface. (10) when handling lcd module and assembling them into cabinets, be noted that storage in the environment of oxidization or deoxidization gas and the use of such materials as reagent, solvent, adhesive, resin , and etc. which generate these gasses, may cause corrosion and discoloration of lcd modules . (11)to avoid picture uniformity failure, do not put a seal or an adhesive material on the panel surface. (12) do not use chloroprene rubber as it generates chlorine gas and affects reliability in lcd panel connective area. (1 3 ) protective film is attached to the surface of polarizer film on lcd panel to prevent scratches or other damages. remove this protective film before use. in addition, do not attach the protective film which is removed from lcd module again. when the lcd panel which has the reattached protective film is needed to storage for a long time, the polarizer film might have a damage with picture quality failure. (14) p anel is suscepti ble to mechanical stress and such stress may affect the display. place the panel on flat surface to avoid str ess caused by twist, bend, etc. (15) when transporting lcd panels, secure them in lcd panel tray to avoid mechanical stress. the tray should be c onductive to protect lcd panels from static charge. material used in set or epoxy resin (amine type hardening agent) from packaging, and silicon adhesive (dealcoholized or oxime) all release gas which may affect quality of polarizer film . do confirm compa tibility with user materials. (16) as this lcd module is composed electronic circuit s, it is sensitive to electrostatic discharge of 200v or more. handle with care using cautions for the followings: ? operators operators must wear anti - static wears to preve nt electrostatic charge up to and discharge from human body.
spec no. lcy - 12t09 602c model no. ls027b4d h 01 page 3 ? equipment and containers process equipment such as conveyer, soldering iron, working bench and containers may possibly generate electrostatic charge up and discharge. equipment must be grounded t hrough 100mohms resistance. use ion blower. ? floor floor plays an important role in leaking static electricity generated in human body or equipment. if the floor is made of insulated material (such as polymer or rubber material), such static electricity ma y charge. proper measure should be taken to avoid static electricity charge (electrostatic earth: 100mohms). there is a possibility that the static electricity is charged to them without leakage in case of insulating floor, so t he electrostatic earth:110 8 should be made. ? humidity humidity in work area relates to surface resistance of the persons or objects that generate e lectrostatics, and it can be manipulated to prevent electrostatic charge. humidity of 40% or lower increases electrostatic earth resist ance and promotes electrostatic charging. therefore, the humidity in the work area should be kept above 40%. specifically for film peeling process or processes that require human hands, humidity should be kept above 50% and use electricity removal blower . ? transportation/ s torage containers and styroform used in transporation and storage may charge electrostatic (from friction and peeling) or electrostatic charge from human body, etc. may cause containers and styroform to have induced charge. proper elect rostatic measure should be taken for containers and storage material.
spec no. lcy - 12t09 602c model no. ls027b4d h 01 page 4 [for operating lcd module] (1) do not operate the lcd panel under outside of electrical specification. otherwise lcd panel may be damaged. (2) do not use the lcd panel under outside o f specified driving timing chart. otherwise lcd panel may not have proper picture quality. (3) a still image should be displayed less than two hours, if it is necessary to display still image longer than two hour, display image data must be refreshed in or der to avoid sticking image on lcd panel. (4) if lcd module takes a static electricity, as the display image which is written into pixel memory might not be displayed, data update should be executed frequently . [precautions for storage] (1) after open ing the package, do not leave the lcd panel in direct sun or under strong ultraviolet ray. store in dark place. (2) in temperature lower than specified rating, liquid crystal material will coagulate. in temperature higher than specified rating, it isotro pically liquifies. in either condition, the l iquid crystal may not recover its original condition. store the lcd panel in at or around room temperature as much as possible. also, storing the lcd panel in high humidity will damage the polarizer. store in normal room temperature as much as possible. (3) keeping method a no direct sun light b store in trays and in dark room
spec no. lcy - 12t09 602c model no. ls027b4d h 01 page 5 [other notice] (1) operation outside specified environmental conditions cannot be guaranteed. (2) as power supply (vdd - gnd vdd a - gnd) impedance is lo wered during use, bus controller should be inserted near lcd module as much as possible. (3) p olarizer film is applied over lcd panel surface. liquid crystal inside lcd panel deteriorates with ultraviolet ray. the panel should not be left in direct sun or un der strong ultraviolet ray for prolonged period of time even with the polarizer film . (4) disassembling the lcd module will cause permanent damage to the module. do not disassemble the module. (5) if lcd panel is broken, do not ingest the liquid crystal from the broken panel. if hand, leg, or clothes come in contact with liquid crystal, wash off immediately with soap. (6) ods (specific chlorofuorocarbon, specific halon, 1 - 1 - 1 trichloroethane, carbon tetrachloride) are not used or contained in material or all producti on processes of this product. (7) observe all other precautionary requirements in handling general electronic components. discarding liquid crystal modules lcd panel : dispose of as glass waste. this lcd module contains no harmful substances. the liq uid crystal panel contains no dangerous or harmful substances. this liquid crystal panel contains only an extremely small amount of liquid crystal (approximately 100mg) and therefore it will not leak even if the panel should break. it s median lethal do se (ld50) is greater than 2,000 mg/kg and a mutagenetic (aims test: negative) material is used. fpc : (1) fpc bend r should be 0.45mm or greater and r should be even. in lcd panel an connective area, do not bend fpc into polarizer film side. (2) do not hang lcd module by fpc or apply force to fpc.
