l Contrast ratio should be greater than 50% of the initial value.

10 USE PRECAUTIONS

10.1 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.

Company Confidential Ver

MB-TFT-35-S4-S

4) If the LCD element breaks and any LC stuff leak, do not suck or lick it. Also

if LC stuff is stuck on your skin or clothing, wash thoroughly with soap and

water immediately.

10.2 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.

10.3 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.

10.4 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

Company Confidential Ver

MB-TFT-35-S4-S

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, the LC

drive voltage affects crosstalk. Design the contents of the display, considering

crosstalk.

10.5 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.
