4dlcd - 32 qa datasheet ? 2012 4d systems www.4d systems .com .au page 11 of 14 o do not alter, modify or change the shape of the tab on the metal frame. o do not make extra holes on the printed circuit board, modify its shape or change the positions of components to be attached. o do not damage or modify the pa ttern writing on the printed circuit board. o absolutely do not modify the zebra rubber strip (conductive rubber) or heat seal connector. o do not drop, bend or twist lcm. 6.2 storage precautions ? when storing the lcd modules, the following precaution is necessary. ? store them in a sealed polyethylene bag. if properly sealed, there is no need for the desiccant. ? store them in a dark place. do not expose to sunlight or fluorescent light, keep the temperature between 0 and 35 , and keep the relative humidity between 40%rh and 60%rh. ? the polarizer surface should not come in contact with any other objects. (we advis e you to store them in the anti - static electricity container in which they were shipped. others liquid crystals solidify under low temperature (below the storage temperature range) leading to defective orientation or the generation of air bubbles (black or white). air bubbles may also be generated if the module is subject to a low temperature. ? if the lcd modules have been operating for a long time showing the same display patterns, the display patterns may remain on the screen as ghost images and a slight contrast irregularity may also appear. a normal operating status can be regained by suspending use for some time. it should be noted that this phenomenon does not adversely affect performance reliability. ? to minimize the performance degradation of the lcd modules resulting from destruction caused by static electricity etc., exercise care to avoid holding the following sections when handling the module s o exposed area of the printed circuit board o terminal electrode sections

4dlcd - 32 qa datasheet ? 2012 4d systems www.4d systems .com .au page 13 of 14 5. slight dew depositing on terminals is a cause for electro - chemical reaction resulting in terminal open circuit. usage under the maximum operating temperature, 50%rh or less is required. 6. input each signal after the positive/negative voltage becomes sta ble. 7. 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. 7.3 safety ? it is recommended to crush damaged or unnecessa ry lcds into pieces and wash them off with solvents such as acetone and ethanol, which should later be burned. ? if any liquid leaks out of a damaged glass cell and comes in contact with the hands, wash off thoroughly with soap and water. limited warranty. 7.4 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 is damaged or modified. ? pcb conductors damaged. ? circuit modified in any w ay, including addition of components. ? pcb tampered with by grinding, engraving or painting varnish. module repairs will be invoiced to the customer upon mutual agreement. modules must be returned with s ufficient description of the failures or defects. any connectors or cable installed by the customer must be removed completely without damaging the pcb eyelet, conductors and terminals.
