9. precautions for use of lcd modules 9.1. handling procedures a) the display panel is made of glass. do not subject it to a mechanical shock. b) if the display panel is damaged, the liquid crystal substance inside may leak out. avoid contact with the mouth. if the substance comes into contact with the your skin or clothes, promptly wash the area thoroughly using soap and water. c) do not touch or apply excessive force on the surface of the display or the adjoining area of the lcd module since this may cause the color tone/contrast ratio to vary. d) under the protective film the polarizer covering the display surface of the lcd module is soft and easily scratched. handle this polarizer ca refully and keep in a dust free environment. e) if the display surface of the lcd module becomes contaminated, breathe on the surface and gently wipe it with a soft dry cloth. if it is heavily contaminated, moisten cloth with one of following solvents, either isopropyl or ethyl alcohol solvents other than those mentioned above may damage the polarizer. do not use water, acetone, and aromatic solvents. f) when positioning the lcd module, ensure that it is free of twisting, warping, and tension. strain has a great influence upon display quality. also, ensure that enough room is left for possible shifting of the outer case/housing. g) when installing the lcd module, do not forcibly pull or bend the i/o cable. h) do not touch the ic of the lcd module, as this may cause abnormal readings that cannot be corrected. i) do not attempt to disassemble or modify the lcd module. j) no connection terminals should be left open. do not connect anything. k) if the logic circuit power is off, do not try to apply input signals. l) to prevent damage to the various components of t he display from static electricity, normal anti static techniques must be used. tools required for assembly, such as soldering irons, must be properly earthed to minimize the amount of static electricity generated. try to avoid assembly and other work under very dry conditions. the lcd module is coated with a film to protect the display surface. exercise care when peeling off this protective film since static electricity may be generated. m) avoid handling the lcd glass, as the edges are sharp. 9.2 storage precautions a) exercise care to minimize possible corrosion or contamination of the electrical contacts. moisture condensation or a current flow in a high humidity environment accelerates corrosion of the contacts. b) when storing the lcd module, avoid exposure to di rect sunlight or to the light of fluorescent lamps. keep the lcd module in bags designed to prevent static electricity build up under low ambient temperature/normal humidity conditions. avoid high temperature /high humidity and low temperatures, below 0 oc. whenever possible, the lcd module should be stored in the same packaging in which they were palm technology co., ltd. t el:886-7-3983966 fax:886-7-3982966 PFG38A-SCF-1 page:23/26
shipped from our company. 9.3 design precautions a) the absolute maximum ratings represent the rated value beyond which the lcd module must not be used. if the lcd module is used in excess of the rated values, their operation characteristics may be adver sely affected permanently. b) to prevent the occurrence of erroneous or poor operation caused by electromagnetic noise, attention must be paid to the vil, vih specification values, including taking the precaution of using short signal cables whenever possible. c) the liquid crystal display characteristics are temperature dependent. viewing clarity of the display becomes poorer when the lcd is used outside its designated operating temperature range. it is therefore recommended that the lcd be used within this range. d) we recommend that power supply lines (vdd or vcc) have over-current protection precautions. (fuse etc.) e) to minimize electro magnetic interference, designs using lcd modules should recognize the effect of components elsewhere, especially from adjacent peripheral devices. f) the tape carrier package fixes the lcd module, consisting of a glass panel, inside the housing. if the pcb is fixed, it could be disconnected when subjected to stress. 9.4. cog precautions a) although these modules have a built-in protection terminal against static electricity for all pins, this may not be sufficient if higher levels of static electricity are encountered, possibly leading to a short circuit. therefore, care in anti static handling is very important, including using earthen straps for the operators b) generally, irradiating it with a strong light will change the characteri stics of a semiconductor device. this may adversely affect the operational characteristics of the ic in the modules. we recommend whenever possible that: handling, preparation, assembly, and testing involving lcd are carried out in the lowest possible lighting conditions, consistent with operator comfort. 9.5. other considerations a) liquid crystal material solidifies at low temperatures (below the storage temperature range) leading to defective orientation of the liquid crystal or the generation of air bubbles. air bubbles may also be generated if the lcd module is subjected to a strong shock at a low temperature. b) if the lcd module has been operating for a long time showing the same display patterns, there may be retention of the display pattern on the screen as ghost images and a slight contrast irregularity may also appear. normal operating status can be regained by suspending use for some time to rest the display if possible. it should be noted that this phenomenon does not adversely affect the performance reliability. c) to minimize performance reduction of the lcd modules resulting from the adverse effects of static electricity, avoid touching the following areas when handling the modules: ? terminal connections ? parts of pattern wiring on tcp palm technology co., ltd. t el:886-7-3983966 fax:886-7-3982966 PFG38A-SCF-1 page:24/26
9.6. w arranty a) acceptance inspection period the period is one month after the arrival of contracted commodity at the customer's factory site. b) general w arranty period the general warranty period is one year from the date when the product was shipped out from palm technology co., ltd however, the warranty is applicable only when the product has been handled and/or stored under normal conditions that at no time violate above-mentioned precautions. c) the warranty liability of palm techology co., ltd. is limited to repair and/or replacement. the disregard of any one of above precautions invalidates the warranty in its entirety. d) palm technology co., ltd.is not to be held responsible for any subsequent or con sequential events. palm technology co., ltd. t el:886-7-3983966 fax:886-7-3982966 PFG38A-SCF-1 page:25/26
