MODULE NO.: GS-GGGS-GG1286456FFWJ-A/R 7. HANDLING PRECAUTION 7.1 Handling precautions 1.The display panel is made of glass. Do not subject it to a mechanical shock or impact by dropping it. 2.If the display panel is damaged and the liquid crystal substance leaks out, be sure not to get any in your mouth. If the substance contacts your skin or clothes, wash it off using soap and water. 3.Do not apply excessive force to the display surface or the adjoining areas since this may cause the color tone to vary. 4.The polarizer covering the display surface of the LCD module is soft and easily scratched. Handle this polarizer carefully. 5.If the display surface becomes contaminated, breathe on the surface and gently wipe it with a soft dry cloth. If it is heavily contaminated, moisten a cloth with one of the following solvents: - Isopropyl alcohol -Ethyl alcohol 6.Solvents other than those above mentioned may damage the polarizer. Especially, do not use the following: water, ketene, aromatic solvents. 7.Extra care to minimize corrosion of the electrode. Water droplets, moisture condensation or a current flow in a high-humidity environment accelerates corrosion of the electrode. 8.Install the LCD module by using the mounting holes. When mounting the LCD module, make sure it is free of twisting, warping and distortion. In particular, do not forcibly pull or bend the I/O cable or the backlight cable. 9.Do not attempt to disassemble or process the LCD module. 10.NC terminal should be open. Do not connect anything. 11.If the logic circuit power is off, do not apply the input signals. 12.To prevent destruction of the elements by static electricity, be careful to maintain an optimum work environment. Be sure to ground the body when handing he LCD module. Tools required for assembling, such as soldering irons, must be properly grounded. To reduce the amount of static electricity generated, do not conduct assembling and other work under 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. 7.2 STORAGE CONDITIONS When storing. avoid the LCD module to be exposed to direct sunlight of fluorescent lamps. For stability, to keep it away form high temperature and high humidity environment (The best condition is :23±5, 45±10%RH). ESD protection is necessary for long-term storage also. 7.3 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 module have been operating for a long time showing the same display patterns may remain on the screen as ghost images and a slight contrast irregularity may also appear. A normal operating status can be recovered by suspending use for some time. It should be noted that this phenomenon does not adversely affect performance reliability. P.6
To minimize the performance degradation of the LCD Module resulting from destruction caused by static electricity etc. exercise care to avoid holding the following sections when handling the modules. -Exposed area of the printed circuit board. -Terminal electrode sections. 8. ELECTRICAL CHARACTERISTIC MAXIMUM ABSOLUTE LIMIT Characteristic Symbol Value Unit Supply voltage rage V DD -0.3 to +7.0 V V lcd -0.3 to +17 V Input voltage rage VIN -0.3 to V DD +0.3 V Operating temperature T OPR -20 to +70 C Storage temperature T STG -30 to +80 C NOTES: 1) VDD and VLCD are based on VSS=0V 2) Voltages V0 V1 V2 V3 V4 VSS must always be satisfied(vlcd=v0-vss) 3) If supply voltage exceed its absolute maximum range.this LSI may be damaged permanently. It Is desirable to use this LSI under electrical characteristic conditions during general operation. Otherwise,This LSI may malfunction or reduced LSI reliability may result. P.7
