Product Features

The FFP touch panel mainly offers the following features:

conventional film-glass touch panels because the specific

gravity of plastic is approximately half that of glass.

Plastic plate

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.

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

requirements for high writing pressure or pen knocking.

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.

has been achieved.

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.

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.
