LCD is made of glass. Care must be exercised to avoid dropping it or subjecting it to strong mechanical shocks, and the following precautions should be taken when handling LCD.


1. If the LCD panel beaks, do not allow the liquid crystal to get in your mouth. Ifthe liquid crystal touches your skins or clothes, wash it immediately with soap and water.


2. Glass can be easily chipped or cracked from rough handling. Care must be excercised to keep the area free of unreasonable pressure.


3. The polarizer covering the display source is soft and easily scratched, handle with care.


4. Do not soil or damage LCD panel terminals.


5. Keep the display surface clean and do not touch it with your skin.


6. Do not touch the exposed polarizers with anything harder than an HB pencil lead. To clean dust off the display surface, wipe gently with cotton, chamois or other soft material soaked in petroleum benzin. Never scrub hard. Wipe off saliva, water or solvent droplets immediately. Contact with water over a prolonged period may cause polarizer to deform or its color to fade.


7. Chemicals such as acetone, toluene, ethanol and isopropyl alcohol will damage the polarizers. Avoid oil and fat. Avoid lacqueer and epoxy which might contain solvents and hardeners that erode the electrodes. Some solvents such as freon or trichloroethane will also seep into the epoxy covering the DIL pins and thereby cause corrosion of the connection.


8. When soldering DIL pins, avoid excessive heat, keep soldering temperature
between 260~C to 300~C and apply heat for more than 5 seconds. Never use
wave or refiow soldering. The LCD surface should be covered to avoid flux
spatter. Flux residues should be removed afterward.


9. Do not drive LCD with DC voltage. Keep driving voltage within specified limit. Excessive voltage shortens display lifetime. Within limit, the viewing angle can be fine tuned by varying the LCD driving voltage, particularly in the case of STN. Response time increases with decreasing temperature.


10.Dot not apply pressure to CCFL. It may be damaged.


11.LCD should be stored in a dark place at 25 ~C+ 10 ~C and 65% RH maximum. Stored away from direct sunlight and fluorescent light.


12.Do not store where there are organic solvents or corrosive gases. Dot not crush, vibrate, or jolt the module or its components.
