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 I LED of
the LED back-light should be follow :

White chromaticity
Note 1: Note 1:Ambient temperature=25℃,and lamp current I LED =20mA.To be
measured in the dark room.
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 V i =V i50 +1.5V
Black V i =V i50 +2.0V
“±”means that the analog input signal swings in phase with V COM signal.
“ “ means that the analog input signal swings out of phase with V COM signal.
V i50 : 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.

11 QUALITY AND RELIABILITY
11.1 TEST CONDITIONS
Tests should be conducted under the following conditions:
Ambient temperature: 25 ± 5°C
Humidity
: 60 ± 25% RH.
11.2 SAMPLING PLAN
Sampling method shall be in accordance with MIL-STD-105E, level II,
normal single sampling plan .
11.3 ACCEPTABLE QUALITY LEVEL
A major defect is defined as one that could cause failure to or materially
reduce the usability of the unit for its intended purpose. A minor defect is one that
does not materially reduce the usability of the unit for its intended purpose or is an
infringement from established standards and has no significant bearing on its
effective use or operation.
11.4 APPEARANCE
An appearance test should be conducted by human sight at approximately
30 cm distance from the LCD module under fluorescent light. The inspection area of
LCD panel shall be within the range of following limits.

12 USE PRECAUTIONS
12.1 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.
12.2 Installing precautions
1) 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.
12.3 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.
12.4 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.

12.5 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 warrantee for all products and three months
warrantee for all repairing products.
