10. PRECAUTIONS FOR USING LCD MODULES 
10.1. 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 
(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 
- Ketone 
- 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 handling 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.
