spec no. lcy-1210401a model no. LS027B7DH01 page 2 [for handling and system design] (1) handle with care as glass is used in this lcd panel. dropping or contact against hard object may cause cracks or chips. (2) be careful to handle this lcd panel in order to avoid inju ry 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 i mmediately as they may cause color changes, or other defects if remained for a long time. (5)do not leave the lcd panel in direct sun or under ultraviolet ray. (6) to clean lcd panel surface, wipe cl ean with absorbent cotton or soft cloth. if further cleaning is needed, use ipa (isopropyl alcohol) and wipe cle an lightly on surface only. do not use or ganic solvents as it may damage the lcd panel terminal area which uses organic material. also, do not directly touch with finger. when 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 t he 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 designed to av oid stress that exceeds specif ication on glass surface. (10) when handling lcd module and assembling them into cabi nets, 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 corros ion and discoloration of lcd modules. (11)to avoid picture uniformity failure, do not put a se al 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. (13) protective film is attached to both of surface polariz er films (front polarizer and rear polarizer) on lcd panel to prevent scratches or other damages. remove these protective films before use. in addition, do not attach the protective films which are removed from lcd module again. when the lcd panel which has the reattached protective film is needed to storage for a long time, the polar izer film might have a damage with picture quality failure. (14) panel is susceptible to mechanical stress and such stress may affect the display. place the panel on flat surface to avoid stress caused by twist, bend, etc. (15) when transporting lcd panels, secure them in lcd panel tray to avoid mechanical stress. the tray should be conductive 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 qua lity of polarizer film. do c onfirm compatibility with user materials. (16) as this lcd module is composed electronic circuits, it is sensitive to electrostatic discharge of 200v or more. handle with care using cautions for the followings: z operators operators must wear anti-static wears to prevent electrostatic charge up to and discharge from human body.
spec no. lcy-1210401a model no. LS027B7DH01 page 3 z equipment and containers process equipment such as conveyer, soldering iron, working bench and containers may possibly generate electrostatic charge up and discharge. equipmen t must be grounded through 100mohms resistance. use ion blower. z floor floor plays an important role in leaking static electr icity generated in human body or equipment. if the floor is made of insulated material (such as polymer or rub ber material), such static electricity may charge. proper measure should be taken to avoid static electric ity charge (electrostatic earth: 100mohms).there is a possibility that the static electricit y is charged to them without leakage in case of insulating floor, so the electrostatic earth:110 8 ? should be made. z humidity humidity in work area relates to surface resist ance of the persons or objects that generate electrostatics, and it can be manipulated to prevent electrostatic charge. humidity of 40% or lower increases electrostatic earth resistance and promotes electrostatic charging. therefore, the humidity in the work area should be kept ab ove 40%. specifically for film peeling process or processes that require human hands, humidit y should be kept above 50% and use electricity removal blower. z transportation/storage 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 electrostatic measure should be taken for containers and storage material.
spec no. lcy-1210401a model no. LS027B7DH01 page 4 [for operating lcd module] (1) do not operate the lcd panel under outside of electric al specification. otherwise lcd panel may be damaged. (2) do not use the lcd panel under outside of specifi ed 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 order to avoid sticking image on lcd panel. (4) if lcd module takes a static electric ity, as the display image which is wr itten into pixel memory might not be displayed, data update should be executed frequently. [precautions for storage] (1) after opening the package, do not leave the lcd panel in di rect sun or under strong ultraviolet ray. store in dark place. (2) in temperature lower than specified rating, liquid crysta l material will coagulate. in temperature higher than specified rating, it isotropically liquifies. in either condi tion, the liquid 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-1210401a model no. LS027B7DH01 page 5 [other notice] (1) operation outside specified environment al conditions cannot be guaranteed. (2) as power supply (vdd-gnd vdda-gnd) impedance is lowered during use, bus controller should be inserted near lcd module as much as possible. (3) polarizer 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 under strong ultraviolet ray for prolonged period of time even with the polarizer film. (4) disassembling the lcd module will cause permanent dam age 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 production processes of this product. (7) observe all other precautionary requirement s in handling general electronic components. discarding liquid crystal modules lcd panel : dispose of as glass waste. this lcd module contains no harmful substances. the liquid 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 w ill not leak even if the panel should break. its median lethal dose (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.
