11. PRECAUTION IN DESIGN
11.1 LC DRIVING VOLTAGE (VEE) AND VIEWING ANGLE RANGE
Setting VEE out of the recommended condition will be a cause for a change of
viewing angle range.
11.2 PRECAUTIONS AGAINST STATIC CHARGE
As this module contains C-MOS LSIs , it is not strong against electrostatic discharge.
Make certain that the operator’s body is connected to the ground through a list
band etc. And don’t touch I/F pins directly.
11.3 POWER ON SEQUENCE
Input signals should not be applied to LCD module before power supply voltage is
applied and reaches to specified voltage (VDD).
If above sequence is not kept, C-MOS LSIs of LCD modules may be damaged due
to latch up problem.
11.4 PACKAGING
(1) No leaving product is preferable in the place of high humidity for a long period of
time. For their storage in the place where temperature is 35 ℃ or higher ,special care
t o p r e v e n t t he m f r o m hi gh h um i d ity i s r e q ui r e d. A c om b in a t io n of high temperature and
high humidity may cause them polarization degradation as well as bubble generation
and polarizer peel-off. Please keep the temperature and humidity within the specified
range for use and storage.
(2) Since polarizers tend to be easily damaged, They should be handled full
with care so as not to get them touched, pushed or rubbed.
(3) As the adhesives used for adhering polarizers are made of organic substances
which will be deteriorated by a chemical reaction with such chemicals as acetone, toluene ,
ethanol and isopropyl alcohol. The following solvents are recommended for use:
normal hexane
Please contact us when it is necessary for you to use chemicals.
(4) Lightly wipe to clean the dirty surface with absorbent cotton waste or other soft
material like chamois , soaked in the chemicals recommended without scrubbing it
hardly. To prevent the display surface from damage and keep the appearance in good
s t a t e , i t i s s u f f ici e n t , in g ene r a l , t o w ip e it with absorbent cotton.
(5) Immediately wipe off saliva or water drop attached on the display area because its
long period adherence may cause deformation or faded color on the spot.
(6) Foggy dew deposited on the surface due to coldness will be caused for polarizer
damage, stain and dirt on product. When necessary to take out the products from
some place at low temperature for test, etc. It is required for them to be warmed
up in a container once at the temperature higher than that of room.
(7) Touching the display area and contact terminals with bare hands and contaminating
them are prohibited, because the stain on the display area and poor insulation
between terminals are often caused by being touched by bare hands.
(Some cosmetics are detrimental to polarizers.)
