2) Exercise care to minimize corrosion of the electrodes. Corrosion of the electrodes is
accelerated by water droplets or a current flow in a high humidity environment.
10.3 Design Precautions
1) The absolute maximum ratings represent the rated value beyond which LCD module
can not exceed. When the LCD modules are used in excess of this rated value, their
operating characteristics may be adversely affected.
2) To prevent the occurrence of erroneous operation caused by noise, attention must
be paid to satisfy VIL, VIH specification values, including taking the precaution of
using signal cables that are short.
3) The liquid crystal display exhibits temperature dependency characteristics. Since
recognition of the display becomes difficult when the LCD is used outside its
designated operating temperature range, be sure to use the LCD within this range.
Also, keep in mind that the LCD driving voltage levels necessary for clear displays
will vary according to temperature.
4) Sufficiently notice the mutual noise interference occurred by peripheral devices.
5) To cope with EMI, take measures basically on outputting side.
6) If DC is impressed on the liquid crystal display panel, display definition is rapidly
deteriorated by the electrochemical reaction that occurs inside the liquid crystal
display panel. To eliminate the opportunity of DC impressing, be sure to maintain the
AC characteristics of the input signals sent to the LCD Module.
10.4 Others
1) Liquid crystals solidify under low temperatures (below the storage temperature range)
leading to defective orientation or the generation of air bubbles (black or white).
Air bubbles may also be generated if the LCD module is subjected to a strong shock
at a low temperature.
2) If the LCD modules have been operating for a long time showing the same display
patterns, the display patterns may remain on the screen as ghost images and a
slight contrast irregularity may also appear. A normal operating status can be
regained by suspending use for some time. It should be noted that this phenomenon
does not adversely affect performance reliability.
3) To minimize the performance degradation of the LCD modules resulting from
destruction caused by static electricity, etc., exercise care to avoid touching the
following sections when handling the module:
· Terminal electrode sections.
· Part of pattern wiring on TAB, etc.
