(6) Mounting the touch panel
Make sure the bezel tip falls between the input area and the
transparent area. If the bezel tip extends into the input area, when
the bezel is pressed the tip may press on the touch panel and
result in input.
Provide a gap of approximately 0.5mm between the inside of the
bezel and top surface of the upper electrode of the touch panel. A
narrow gap between the bezel and the upper electrode of the touch
panel may result in unanticipated input.
When installing buffer materials between the inside of the bezel
and the upper electrode of the touch panel, provide a certain
amount of leeway to absorb differences in expansion and
contraction between the bezel and the upper electrode due to
temperature changes. If the buffer materials are firmly clamped,
they may be unable to fully absorb the expansion and contraction,
which may cause warping or deflection of the upper electrode of
the touch panel, possibly affecting both the appearance and
performance of the touch panel.
In addition, be sure to insert the buffer materials to the inside of the
insulated area.
The touch panel and the tail dimensions have tolerances of ± 0.2 to
0.3mm, so be sure to provide leeway of this amount between the
case and the connector.
Do not use a structure where the tail is strongly clamped, bent
sharply at the base, or otherwise subject to stress due to case
pressure or other factors. Otherwise, insulation defects or
disconnected circuits may result.
Be sure to use a structure that supports the touch panel from the
bottom such as by adhering the touch panel to the display. If the
structure adheres the inside of the bezel to the upper electrode of
the touch panel, the joint between the upper and lower electrodes
will be subject to stress and easily damaged.
