13. RELIABILITY 14. USING LCD MODULES 14-1. Liquid Crystal Display Modules LCD is composed of glass and polarizer. Pay attention to the following items when handling. 1. Please keep the temperature within specified range for use and storage. Polarization degradation, bubble generation or polarizer peel-off may occur with high temperature and high humidity. 2. Do not touch, push or rub the exposed polarizers with anything harder than an HB pencil lead (glass, tweezers, etc). 3. N-hexane is recommended for cleaning the adhesive used to attach front/rear polarizers and reflectors made of organic substances which will be damaged by chemicals such as acetone, toluene, ethanol and isopropylalcohol. 4. When the display surface becomes dusty, wipe gently with absorbent cotton or other soft material like chamois soaked in petroleum benzin. Do not scrub hard to avoid damaging the display surface. 5. Wipe off saliva or water drops immediately, contact with water over a long period of time may cause deformation or color fading. 18
6. Avoid contacting oil and fats. 7. Condensation on the surface and contact with terminals due to cold will damage, stain or dirty the polarizers. After products are tested at low temperature they must be warmed up in a container before coming is contacting with room temperature air. 8. Do not put or attach anything on the display area to avoid leaving marks on. 9. Do not touch the display with bare hands.this will stain the display area and degradate insulation between terminals (some cosmetics are determinated to the polarizers). 10. As glass is fragile. It tends to become or chipped during handling especially on the edges. Please avoid dropping or jarring. 14-2. Precaution for Handling LCD Modules Since LCM has been assembled and adjusted with a high degree of precision, avoid applying excessive shocks to the module or making any alterations or modifications to it. 1. Do not alter, modify or change the shape of the tab on the metal frame. 2. Do not make extra holes on the printed circuit board, modify its shape or change the positions of components to be attached. 3. Do not damage or modify the pattern writing on the printed circuit board. 4. Absolutely do no modify the zebra rubber strip (conductive rubber) or heat seal connector. 5. Except for soldering the interface, do not make any alterations or modifications with a soldering iron. 6. Do not drop, bend or twist LCM. 14-3. Electro-Static Discharge Control Since this module uses a CMOS LSI, the same careful attention should be paid to electrostatic discharge as for an ordinary CMOS IC. 1. Make certain that you are grounded when handing LCM. 2. Before remove LCM from its packing case or incorporating it into a set, be sure the module and your body have the same electric potential. 3. When soldering the terminal of LCM, make certain the AC power source for the soldering iron does not leak. 4. When using an electric screwdriver to attach LCM, the screwdriver should be of ground potentiality to minimize as much as possible any transmission of electromagnetic waves produced sparks coming from the commutator of the motor. 5. As far as possible make the electric potential of your work clothes and that of the work bench the ground potential. 6. To reduce the generation of static electricity be careful that the air in the work is not too dried. A relative humidity of 50%~60% is recommended. 19
14-4. Precaution for soldering to the LCM 1. Observe the following when soldering lead wire, connector cable and etc. to the LCM. - Soldering iron temperature: 280 ±10 - Soldering time: 3-4 sec. - Solder: eutectic solder. If soldering flux is used, be sure to remove any remaining flux after finishing to soldering operation. (This does not apply in the case of a non- halogen type of flux.) It is recommended that you protect the LCD surface with a cover during soldering to prevent any damage dug to flux spatters. 2. When soldering the electroluminescent panel and PC board, the panel and board should not be detached more than three times. This maximum number is determined by the temperature of the soldering iron. 3. When remove the electroluminescent panel form the PC board, be sure the solder has completely melted, the soldered pad on the PC board could be damaged 14-5. Precaution for Operation 1. Viewing angle varies with the change of liquid crystal driving voltage (Vo). Adjust Vo to show the best contrast. 2. Driving the LCD in the voltage above the limit shortens its life. 3. Response time is greatly at temperature below the operating temperature range. However, this does not mean the LCM will be out of the order. It will recover when it returns to the specified temperature range. 4. If the display area is pushed hard during operation, the display will become abnormal. However, it will return to normal if it is turned off and then back on. 5. Condensation of terminals can cause an electrochemical reaction disrupting the terminal circuit. Therefore, it must be used under the relative condition of 40,50%RH. 6. When turning the power on, input each signal after the positive/negative voltage becomes stable. 20
14-6. Storage When storing LCD as spares for some years, the following precaution are necessary. 1. Store them in a sealed polyethylene bag. If properly sealed, there is no need for dessicant. 2. Store them in a dark place. Do not expose to sunlight or fluorescent light, keep the temperature between 0 and 35. 3. The polarizer surface should not come in contact with any other objects. (We advise you to store them in the container in which they were shipped.) 4. Environmental conditions: - Do not leave them for more than 168hrs. at 60. - Should not be left for more than 48hrs. at -20. 14-7. Safety 1. It is recommended to crush damaged or unnecessary LCD into pieces and wash off with solvents such as acetone and ethanol, which should later be burned. 2. If any liquid leak out of a damaged glass cell and comes in contact with the hands, wash off thoroughly with soap and water. 14-8. Limited Warranty Unless agreed between CCT and customer, CCT will replace or repair any of its LCD modules which are found to be functionally defective when inspected in accordance with CCT LCD acceptance standards(copies available upon request) for a period of one year from date of shipments. Cosmetic/ visual defects must be returned to CCT within 90 days of shipment. Confirmation of such date shall be based on freight documents. The warranty liability of CCT limited to repair and/or replacement on the terms set forth above. CCT will not be responsible for any subsequent or consequential events. 14-9. Return LCM under warranty No warranty can be granted if the precautions stated above have been disregarded. The typical examples of violations are: - Broken LCD glass. - PCB eyelet s damaged. - PCB conductors damaged. -Circuit modified in any way, including addition of components. - PCB tampered with by grinding, engraving or painting varnish. -Soldering to or modifying the bezel in any manner. Module repairs will be invoiced to the customer upon mutual agreement. Modules must be returned with sufficient description of the failures or defects. Any connectors or cable installed by the customer must be removed completely without damaging the PCB eyelet s conductors and terminals 21
