FID-533 Series
Film-Film-Plastic Touch Panel
FID-533 Series
A film-film-plastic (FFP) touch panel is lightweight, has excellent impact resistance, and
can be designed in any shape. The impact resistance is dramatically improved and
higher reliability is realized in durability and environmental-resistance features by
removing glass from structural components.
Touch panels are used in a wide range of applications as simple
and reliable means to input directly to display screen. Especially,
4-wire*1 resistive touch panels are most widely adopted because of
their simple structure and low product cost. They are now utilized
in various mobile devices such as digital video cameras, cellular
phones, portable data terminals (PDTs) and portable game
machines. It is expected that their application will further diversify
and lead to an expansion in the market scale.
As various use environments are considered especially for
PDTs and portable game machines, strict demands exist in
regard to writing endurance and environmental resistance as
well as impact resistance. For example, PDTs have been
introduced in various industries in recent years and suitable
performance is required in usage patterns for product control in
the freezer and transport industries over different areas. Because
of a variety of users, better durability than conventional levels is
essential since they may operate with a bigger input load or
other writing method such as a ballpoint pen. Furthermore, in
addition to safety, to keep original functions is required in
portable game machines even if it is handled roughly or throw
or strike them as they are likely to be used by children.
Conventional film-glass touch panels cannot support these
strict market demands; as such, touch panels with all-plastic
structures are coming to be needed. Film-film-plastic touch
panels (FFP touch panels) can be realized by just affixing a
film-film touch panel onto a plastic plate― it,s possible to
realize this technology with comparatively low cost. In this
way, Fujitsu Component Limited has commercialized the FFP
touch panel so as to satisfy market demands.

Product Features
requirements for high writing pressure or pen knocking.
The FFP touch panel mainly offers the following features:
■ Light weight
The product weight has been reduced 30% to 40% from
conventional film-glass touch panels because the specific
gravity of plastic is approximately half that of glass.
■ Excellent impact resistance
Plastic plate,s material is polycarbonate which has high impact
resistance. Because of it, the FFP touch panel can avoid to be
broken up or cracked by impact or stress and also stay away
from the shattered glass chips.
■ Constituent materials to achieve writing endurance
To respond to the market requirement which pen input is well
used, Fujitsu Component Limited selected the film material which
is suitable to achieve high writing durability and achieved an
optimal combination of top film and bottom film.
Furthermore, it is now possible to achieve operation loads that
are larger than those of conventional products by developing a
series of hard-tapped specifications in which a cover film is
affixed atop the top film to respond to the strict durability
■ High environmental resistance
PDTs are used in various industries and their use environments
are wide from extremely low-temperature to high-temperature,
high-humidity regions. To respond to such a wide range of
operating temperature, we selected appropriate constituent
materials and established a suitable bonding technology.
Consequently, a wide temperature range of −30℃ to +60℃
has been achieved.
■ Flexible shapes and designing freedom
The adoption of plastic materials with good workability allows
the flexible external shape design. As direct printing to plastic
plate is also possible, touch panels with icon sheets or numeric
key indications can easily be realized. That enables to design
touch panel to be suitable for the customer application.
■ Light operability
Optimization of the dot spacer allows light operation with a
pen or finger. In addition, the high hardness of the operation
surface (a pencil hardness of 3H) prevents flaws and provides
an anti-smudge coating that prevents fingerprint staining.

FFP touch panel is suitable for the described applications below
due to its features:
Mobile PCs
Portable data terminals
Portable game machines
Digital cameras and video cameras
To achieve these aims, we plan to explore the adoption of a
flexible organic conductive polymer material for the transparent
conductive film (ITO is currently the conventional material) to
attempt to extend the FFP touch panel lifetime. On the other
hand, we will enhance the development of the FP touch panel
(film-plastic structure touch panel) using a plastic plate on
which the transparent conductive film is directly mounted and
put it on our product lineup to make it possible to meet the
toughest environmental requirements such as automotive
*1: 4-wire touch panel:
Table 1 presents the main specifications of the newly developed
FFP touch panel. Fujitsu Component Limited also provides a
control board, a control IC, and a device driver for each interface.
Future Development
Fujitsu Component Limited will continue to promote further
product development to respond to the customer needs which are
going to diversify more. We will aim to improve the visibility,
durability and environmental resistance of plastic touch panels.
A structure in which a pair of electrodes is established on
both of the opposing transparent conductive films; there are
4 lead wires from the touch panel. Since it has the simplest
structure and a narrow frame in various types of touch
panels, it is possible to meet various sizes from small to
large and signal processing is easy. However, there is a
disadvantage in the durability of the transparent conductive
film (ITO) of the top film and therefore it has some limitations
in regard to writing and input lifetime.
