[Precaution on light]
[Precautions when installing the COG]
Property of semiconductor devices may be affected
when they are exposed to light, possibly resulting in
malfunctioning of the ICs. To prevent such
malfunctioning of the ICs mounted on the boards or
products, make sure that:
(1) Your design and mounting layout done are so that
the IC is not exposed to light in actual use.
(2) The IC is protected from light in the inspection
process.
(3) The IC is protected from light in its front, rear and
side faces.
When installing the COG, it is necessary to duly
consider the fact that there exists a resistance of the
ITO wiring occurring between the driver chip and the
externally connected parts (such as capacitors and
resistors). By the influence of this resistance, non-
conformity may occur with the indications on the
liquid crystal display.
Therefore, when installing the COG design the module
paying sufficient considerations to the following three
points.
1. Suppress the resistance occurring between the
2. Suppress the resistance connecting to the power
3. Make various COG module samples with different
driver chip pin to the externally connected parts
as much as possible.
