20 12. Precautions and Warranty 12.1.Safety The liquid crystal in the LCD is poisonous. Do not put it in your mouth. If the liquid crystal touches your skin or clothes, wash it off immediately using soap and water Since the liquid crystal cells are made of glass, do not apply strong impact on them. Handle with care Handling Reverse and use within ratings in order to keep performance and prevent damage Do not wipe the polarizer with dry cloth, as it might cause scratch. If the surface of the LCD needs to be cleaned, wipe it swiftly with cotton or other soft cloth soaked with petroleum IPA, do not use other chemicals Storage Do not store the LCD module beyond the specified temperature ranges Strong light exposure causes degradation of polarizer and color filter Metal Pin (Apply to Products with Metal Pins) Pins of LCD and Backlight Solder tip can touch and press on the tip of Pin LEAD during the soldering Recommended Soldering Conditions Solder Type: Sn96.3~94-Ag3.3~4.3-Cu0.4~1.1 Maximum Solder Temperature: 370 Maximum Solder Time: 3s at the maximum temperature Recommended Soldering Temp: 350±20 Typical Soldering Time: 3s Solder Wetting Solder Pin Lead Solder Pin Lead Recommended Not Recommended Pins of EL Solder tip can touch and press on the tip of EL leads during soldering No Solder Paste on the soldering pad on the motherboard is recommended Recommended Soldering Conditions Solder type: Nippon Alimit Leadfree SR-34, size 0.5mm Recommended Solder Temperature: 270~290 Typical Soldering Time: 2s Minimum solder distance from EL lamp (body):2.0mm No horizontal press on the EL leads during soldering bend EL leads three times is not allowed. 20/23

21 Solder Wetting Recommended The type of the solder iron: Not Recommended Solder Pad Recommended Not Recommended 12.5.Operation Do not drive LCD with DC voltage Response time will increase below lower temperature Display may change color with different temperature Mechanical disturbance during operation, such as pressing on the display area, may cause the segments to appear fractured Do not connect or disconnect the LCM to or from the system when power is on Never use the LCM under abnormal condition of high temperature and high humidity Module has high frequency circuits. Sufficient suppression to the electromagnetic interface shall be done by system manufacturers. Grounding and shielding methods may be important to minimize the interference Do not display the fixed pattern for long time(we suggest the time not longer than one hour)because it may develop image sticking due to the TFT structure Static Electricity CMOS LSIs are equipped in this unit, so care must be taken to avoid the electro-static charge, by ground human body, etc The normal static prevention measures should be observed for work clothes and benches The module should be kept into anti-static bags or other containers resistant to static for storage Limited Warranty Our warranty liability is limited to repair and/or replacement. We will not be responsible for any consequential loss If possible, we suggest customer to use up all modules in six months. If the module storage time over twelve months, we suggest that recheck it before the module be used After the product shipped, any product quality issues must be feedback within three months, otherwise, we will not be responsible for the subsequent or consequential events. 21/23
