9. Precautions 

Please pay attention to the followings when you use this TFT LCDmodule. 

9-1. Mounting Precautions 

(1) You must mount a module using holes arranged in four cornersor four sides. 
(2) You should consider the mounting structure so that uneven force (ex. Twisted 

stress) is not applied to the module. And the case on which a module is 
mounted should have sufficient strength so that external force is not 
transmitted directly to the module. 

(3) Please attach the surface transparent protective plate to the surface in order to 

protect the polarizer. Transparent protective plate should have sufficient 
strength in order to the resist external force. 

(4) You should adopt radiation structure to satisfy the temperature specification. 
(5) Acetic acid type and chlorine type materials for the cover case are not 

desirable because the former generates corrosive gas of attacking the 
polarizer at high temperature and the latter causes circuit break by 
electro-chemical reaction. 

(6) Do not touch, push or rub the exposed polarizers with glass,tweezers or 

anything harder than HB pencil lead. And please do not rub with dust clothes 
with chemical treatment. Do not touch the surface of polarizer for bare hand or 
greasy cloth.(Some cosmetics are detrimental to the polarizer.) 

(7) When the surface becomes dusty, please wipe gently with absorbent cotton or 

other soft materials like chamois soaks with petroleum benzine.
