LCD has a 7.0 (16:9) inch diagonally measured active display area with WVGA (800
horizontal by 480 vertical pixel) resolution.
(1) Construction: 7” a-Si TFT active matrix, White LED Backlight.
(2) Resolution (pixel): 800(R.G.B) X 480
(3) Number of the Colors : 262K colors ( R , G , B 6 bit digital each)
(4) LCD type : Transmissive , normally White
(5) Viewing Direction: 6 O’clock ( The direction it’s hard to be discolored )
(6) Interface : LVDS interface

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.

11. USE PRECAUTIONS
11.1.
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.
11.2. 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.

AMPIRE CO., LTD.
19
11.3.
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.
11.4.
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,
4)
5)
6)
7)
power voltage etc. Obtain the optimum contrast by adjusting the LC dive voltage.
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.
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.
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.
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.
11.5. 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.
