13. Design guidances for touch panel (T/P)
a) Example of housing design
b) Mounting on display and housing bezel
(1) Keep the gap (over 0.5mm) between the housing-bezel-edge and T/P surface, to avoid the
(2) We recommend inserting cushion material between the housing bezel and the T/P.
(3) Keep the distance (Min0.5mm) between the cushion material to transparent-insulataion-paste.
(4) There is a possibility that the electrode is left in the side edge of T/P.
(1) In all cases, the T/P should be supported from the backside of the plastic housing.
(2) Do not to use an adhesive-tape bonding T/P and the housing bezel.
(3) T/P top layer(PET-film) bulging with internal air, like a balloon. Do not expand the top layer.
(4) Top layer (PET Film) dimension may change with environmental temperature and humidity.
(5) The input to the touch panel sometimes distors touch panel itself.
Otherwise the life of the T/P will be extremely short.
contact. (See the figure above ) Otherwsie, a “short” with bottom Electrode layer may occur.
Otherwise a “short” may occur.
Please design to keep this area insulate from the perimeter to prevent mis-operation and so on.
Please avoid a stress from housing bezel to top layer, because it may cause “waving”.
