12. Design guidance for touchpanel(T/P)
12 - 1.
12 - 2.
(1)If an consumer will put a palm on housing in normal usage, care should be taken as follows.
(3)Insertion a cushion material is recommended.
(4)The cushion material should be limited just on the busbar insulation paste area.
(5)There is one where a resistance film is left in the T/P part of the end of the pole.
(4)Top layer, PET, dimension is changing with environmental temperature and humidity.
(5)The input to the Touchpanel sometimes distorts touch panel itself.
(2)Keep the gap, for example 0.3 to 0.7mm,between bezel edge and T/P surface.
(1)In all cases, the T/P should be supported from the backside of the glass.
(2)Do not to use an adhensive-tape to bond it on the front of T/P and hang it to the housing bezel.
(3)Never expand the T/P top layer(PET-film) like a balloon by internal air pressure.
Insulation Paste
If it is over the transparent insulation paste area, a ”short” may be occurred.
Design to keep insulation from the perimeter to prevent from mis-operation and so on.
Avoid a stress from housing bezel to top layer, because it may cause “waving”.
The reason is to avoid the bezel edge from contacting T/P surface that may cause a “short”
The life of the T/P will be extremely short.
