Uncompromised Performance for Interactive Digital Signage
3M™ Multi-Touch System PCT2420PX
With more than 30 years of capacitive touch sensing expertise, 3M
has developed a scalable multi-touch system for digital signage
applications that demand high-performance multi-touch functionality
with sophisticated bezel-free designs delivering a truly unique touch
experience. The 3M™ Multi-Touch System PCT2420PX portfolio
provides customers with a leading-edge solution that resolves up to
60 simultaneous touches (with palm rejection) at an ultra-fast 12ms
response time for digital signage from 37 to 47 inches. This multi-touch
solution enables display designers to develop cuting-edge interactive
signage solutions that create collaborative spaces for multiple users or
an engaging experiences for single users.
The PCT2420PX multi-touch system exemplifies 3M’s strong system
solution focus by combining 3M proprietary touchscreen manufacturing
technology with the patented 3M™ Multi-Touch Controller PX400 to
overcome existing design challenges in scaling projected capacitive
technology (PCAP) solutions beyond common portable device sizes
(3.5 to 11.6 inches). This system has been designed and engineered
specifically for 37- to 47-inch displays so OEM’s and integrators can
use its unique feature set without settling for scaled-up versions of
mobile handheld electronics and manufacturing processes. With the
PCT2420PX multi-touch system, 3M now offers a wide range of multi-
touch system products that use advanced sensing techniques to address
the unique needs of digital signage applications.
The PCT2420PX system’s non-active, chemically-strengthened cover
glass offers a durable surface that protects the underlying conductive
elements while allowing the touchscreen to remain functional with even
the most severe surface scratches. This same cover glass goes through
an anti-glare treatment process that helps provide an enhanced user
experience by limiting the effects of both touch friction and ambient
light pollution on the sensor. The PCT construction also enables
modern industrial design techniques, such as flat front surfaces, that

to protect any active surface touch components. In addition to adding
sophisticated industrial design, the flat front surface solution eliminates
dust and debris build-up at the edges of the display and also helps
increase overall system reliability by not having critical components on
the touchscreen surface that can be damaged or obstructed.
