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.
