confidential document page: 19 / 21 14. precaution for using lcm 1. liquid crystal display (lcd) lcd is made up of glass, organic sealant, organic fluid, and polymer based polarizers. the following precautions should be taken when handing, (1). keep the temperature within range of use and storage. excessive temperature and humidity could cause polarization degredation, polarizer peel off or bubble. (2). do not contact the exposed polarizers with anything harder than an hb pencil lead. to clean dust off the display surface, wipe gently with cotton, chamois or other soft material soaked in petroleum benzin. (3). wipe off saliva or water drops immediately. contact with water over a long period of time may cause polarizer deformation or color fading, while an active lcd with water condensation on its surface will cause corrosion of ito electrodes. (4). glass can be easily chipped or cracked from rough handling, especially at corners and edges. (5). do not drive lcd with dc voltage. 2. liquid crystal display modules 2.1 mechanical considerations lcm are assembled and adjusted with a high degree of precision. avoid excessive shocks and do not make any alterations or modifications. the following should be noted. (1). do not tamper in any way with the tabs on the metal frame. (2). do not modify the pcb by drilling extra holes, changing its outline, moving its components or modifying its pattern. (3). do not touch the elastomer connector, especially insert an backlight panel (for example, el). (4). when mounting a lcm make sure that the pcb is not under any stress such as bending or twisting . elastomer contacts are very delicate and missing pixels could result from slight dislocation of any of the elements. (5). avoid pressing on the metal bezel, otherwise the elastomer connector could be deformed and lose contact, resulting in missing pixels. 2.2. static electricity lcm contains cmos lsi?s and the same precaution for such devices should apply, namely (1). the operator should be grounded whenever he/she comes into contact with the module. never touch any of the conductive parts such as the lsi pads, the copper leads on the pcb and the interface terminals with any parts of the human body. (2). the modules should be kept in antistatic bags or other containers resistant to static for storage. (3). only properly grounded soldering irons should be used. (4). if an electric screwdriver is used, it should be well grounded and shielded from commutator sparks. (5) the normal static prevention measures should be observed for work clothes and working benches; for the latter conductive (rubber) mat is recommended. (6). since dry air is inductive to static, a relative humidity of 50-60% is recommended. 2.3 soldering (1). solder only to the i/o terminals. (2). use only soldering irons with proper grounding and no leakage. (3). soldering temperature : 280 c 10 c (4). soldering time: 3 to 4 sec. (5). use eutectic solder with resin flux fill. (6). if flux is used, the lcd surface should be covered to avoid flux spatters. flux residue should be removed after wards. 2.4 operation (1). the viewing angle can be adjusted by varying the lcd driving voltage v0. (2). driving voltage should be kept within specified range; excess voltage shortens display life. (3). response time increases with decrease in temperature. (4). display may turn black or dark blue at temperatures above its operational range; this is (however not pressing on the viewing area) may cause the segments to appear ?fractured?. (5). mechanical disturbance during operation (such as p ressing on the viewing area) may cause the segments to appear ?fractured?. 2.5 storage if any fluid leaks out of a damaged glass cell, wash off any human part that comes into contact with soap and water. never swallow the fluid. the toxicity is extremely low but caution should be exercised at all the time. 2.6 limited warranty unless otherwise agreed between data image and customer, data image will replace or repair any of its lcd and lcm which is found to be defective electrically and visually when inspected in accordance with data image acceptance standards, for a period on one year from date of shipment. confirmation of such date shall be based on freight documents. the warranty liability of data image is limited to repair and/or replacement on the terms set forth above. data image will not responsible for any subsequent or consequential events.
