Inspect under 2x20W or 40W fluorescent lamp (approximately 3000 lux) leaving 25 to  
30 cm between the module and the lamp and 30 cm between the module and the eye  
(measuring position).  
Appearance is inspected at the best contrast voltage (best contrast is adjusted  
considering clearness and crosstalk on screen).

Inspect the module at 45° right and left, top and bottom.  
Use the optimum viewing angle during the contrast inspection.

HANDLING PRECAUTIONS  
Safety  
If the LCD panel breaks, be careful not to get the liquid crystal fluid in your mouth or in your eyes.  
If the liquid crystal touches your skin or clothes, wash it off immediately using soap and plenty of  
water.  
Mounting and Design  
Place a transparent plate (e.g. acrylic, polycarbonate or glass) on the display surface to protect the  
display from external pressure. Leave a small gap between the transparent plate and the display  
surface. When assembling with a zebra connector, clean the surface of the pads with alcohol and keep  
the surrounding air very clean. Design the system so that no input signal is given unless the power  
supply voltage is applied.  
Caution during LCD cleaning  
Lightly wipe the display surface with a soft cloth soaked with Isopropyl alcohol, Ethyl alcohol or  
Trichlorotriflorothane. Do not wipe the display surface with dry or hard materials that will damage the  
polariser surface. Do not use aromatic solvents (toluene and xylene), or ketonic solvents (ketone and  
acetone).  
Caution against static charge  
As the display uses C-MOS LSI drivers, connect any unused input terminal to VDD or VSS. Do not  
input any signals before power is turned on.  
Also, ground your body, work/assembly table and assembly equipment to protect against static  
electricity.  
Packaging  
Displays use LCD elements, and must be treated as such. Avoid strong shock and drop from a height.  
To prevent displays from degradation, do not operate or store them exposed directly to sunshine or  
high temperature/humidity.  
Caution during operation  
It is indispensable to drive the display within the specified voltage limit since excessive voltage  
shortens its life. Direct current causes an electrochemical reaction with remarkable deterioration of the  
display quality. Give careful consideration to prevent direct current during ON/OFF timing and during  
operation. Response time is extremely delayed at temperatures lower than the operating temperature  
range while, at high temperatures, displays become dark. However, this phenomenon is reversible and  
does not mean a malfunction or a display that has been permanently damaged. If the display area is  
pushed on hard during operation, some graphics will be abnormally displayed but returns to a normal  
condition after turning off the display once. Even a small amount of condensation on the contact pads  
(terminals) can cause an electro-chemical reaction which causes missing rows and columns. Give  
careful attention to avoid condensation.  
Storage  
Store the display in a dark place where the temperature is 25°C ± 10°C and the humidity below  
50%RH.Store the display in a clean environment, free from dust, organic solvents and corrosive gases.  
Do not crash, shake or jolt the display (including accessories).
