Note3 : Background color changes slightly depending on ambient
temperature. This phenomenon is reversible.
Note4 : The response time will be slower at low temperature.
Note5 : Only operation is guarantied at operating temperature. Contrast ,
response time, another display quality are evaluated at +25℃
Note6 : When LCM is operated over 40℃ ambient temperature, the ILED

Note 2:To be measured on the center area of panel with a viewing cone of 1°by
Topcon luminance meter BM-7,after 10 minutes operation.
Note 3.Definition of response time:
The output signals of photo detector are measured when the input signals
are changed from “black“ to “white”(falling time) and from”white” to “black”
(rising time),respectively.The response time is defined as the time interval
between the 10% and 90% of amplitudes. Refer to figure as below.

Note 4.Definition of contrast ratio:
Contrast ratio is calculated with the following formula.
Contrast ratio(CR)=
Photo detector output when LCD is at ”White” state
Photo detector Output when LCD is at “Black” state
Note 5:White Vi=Vi50 +1.5V
Black Vi=Vi50 +2.0V
“±”means that the analog input signal swings in phase with VCOM signal.
“ “ means that the analog input signal swings out of phase with VCOM
signal.
Vi50 : The analog input voltage when transmission is 50%.The 100%
Transmission is defined as the transmission of LCD panel when all the
Input terminals of module are electrically opened.
Note 6.Definition of viewing angle,Refer to figure as below.

9 USE PRECAUTIONS
9.1
Handling precautions
1) The polarizing plate may break easily so be careful when handling it. Do not
touch, press or rub it with a hard-material tool like tweezers.
2) Do not touch the polarizing plate surface with bare hands so as not to make it
dirty. If the surface or other related part of the polarizing plate is dirty, soak a
soft cotton cloth or chamois leather in benzine and wipe off with it. Do not use
chemical liquids such as acetone, toluene and isopropyl alcohol. Failure to do
so may bring chemical reaction phenomena and deteriorations.
3) Remove any spit or water immediately. If it is left for hours, the suffered part
may deform or decolorize.
4) If the LCD element breaks and any LC stuff leaks, do not suck or lick it. Also if
LC stuff is stuck on your skin or clothing, wash thoroughly with soap and water
immediately.
9.2
Installing precautions
1) The PCB has many ICs that may be damaged easily by static electricity. To
prevent breaking by static electricity from the human body and clothing, earth
the human body properly using the high resistance and discharge static
electricity during the operation. In this case, however, the resistance value
should be approx. 1MΩ and the resistance should be placed near the human
body rather than the ground surface. When the indoor space is dry, static
electricity may occur easily so be careful. We recommend the indoor space
should be kept with humidity of 60% or more. When a soldering iron or other
similar tool is used for assembly, be sure to earth it.
2) When installing the module and ICs, do not bend or twist them. Failure to do
so may crack LC element and cause circuit failure.
3) To protect LC element, especially polarizing plate, use a transparent protective
plate (e.g., acrylic plate, glass etc) for the product case.
4) Do not use an adhesive like a both-side adhesive tape to make LCD surface
(polarizing plate) and product case stick together. Failure to do so may cause
the polarizing plate to peel off.
9.3
Storage precautions
1) Avoid a high temperature and humidity area. Keep the temperature between
0°C and 35°C and also the humidity under 60%.
2) Choose the dark spaces where the product is not exposed to direct sunlight or
fluorescent light.

3) Store the products as they are put in the boxes provided from us or in the
same conditions as we recommend.
9.4
Operating precautions
1) Do not boost the applied drive voltage abnormally. Failure to do so may break
ICs. When applying power voltage, check the electrical features beforehand
and be careful. Always turn off the power to the LC module controller before
removing or inserting the LC module input connector. If the input connector is
removed or inserted while the power is turned on, the LC module internal
circuit may break.
2) The display response may be late if the operating temperature is under the
normal standard, and the display may be out of order if it is above the normal
standard. But this is not a failure; this will be restored if it is within the normal
standard.
3) The LCD contrast varies depending on the visual angle, ambient temperature,
power voltage etc. Obtain the optimum contrast by adjusting the LC dive
voltage.
4) When carrying out the test, do not take the module out of the low-temperature
space suddenly. Failure to do so will cause the module condensing, leading to
malfunctions.
5) Make certain that each signal noise level is within the standard (L level:
0.2Vdd or less and H level: 0.8Vdd or more) even if the module has functioned
properly. If it is beyond the standard, the module may often malfunction. In
addition, always connect the module when making noise level measurements.
6) The CMOS ICs are incorporated in the module and the pull-up and pull-down
function is not adopted for the input so avoid putting the input signal open
while the power is ON.
7) The characteristic of the semiconductor element changes when it is exposed
to light emissions, therefore ICs on the LCD may malfunction if they receive
light emissions. To prevent these malfunctions, design and assemble ICs so
that they are shielded from light emissions.
8) Crosstalk occurs because of characteristics of the LCD. In general, crosstalk
occurs when the regularized display is maintained. Also, crosstalk is affected
by the LC drive voltage. Design the contents of the display, considering
crosstalk.

9.5
Other
1) Do not disassemble or take the LC module into pieces. The LC modules once
disassembled or taken into pieces are not the guarantee articles.
2) The residual image may exist if the same display pattern is shown for hours.
This residual image, however, disappears when another display pattern is
shown or the drive is interrupted and left for a while. But this is not a problem
on reliability.
3) AMIPRE will provide one year warranty for all products and three months
warrantee for all repairing products.
