Cypress’s TrueTouch® Single-Chip Solution for Large Touchscreens Enables Direct Lamination to Sensor-on-Lens Technology

Cypress Semiconductor Corp. (NASDAQ:CY) today announced that its
single-chip TrueTouch® controllers for large touchscreens, the
CY8CTMA884 family, enables large-screen sensor-on-lens technology
with direct lamination to the LCD. With this technology,
manufacturers can deposit the conductive Indium Tin Oxide (ITO)
sensor lines directly onto the cover glass. It only requires one
panel, so tablets can be made much thinner, with less material
costs and fewer manufacturing steps.
The CY8CTMA884 enables the cover glass to be directly laminated
to the LCD with a very thin adhesive layer and no added shield
layer. Many other solutions fail in this configuration because the
increased electrical noise from proximity to the screen interferes
with the ability to correctly interpret touches. Cypress’s
proprietary noise immunity technology and high signal-to-noise
ratio enable flawless performance in this configuration.
“We’re pleased to enable our customers to enjoy the benefits of
sensor-on-lens technology, including thinner devices and lower
costs,” said Derek Richardson, Senior Director of Cypress’s Large
Touchscreen Business Unit. “TrueTouch led the industry by providing
the first single-chip solution for large touchscreens, and we are
doing so again with superior noise immunity and signal-to-noise
ratio enabling economical and sleek new tablets.”
The high-performance, single-chip CY8CTMA884 TrueTouch solution
for large multitouch touchscreens up to 11.6 inches offers 60
sensing I/O channels with support for up to 884 nodes on the
screen, more than any other single-chip solution. Additional
sensing channels are essential for greater accuracy, linearity,
support for smaller sized fingers and the ability to resolve
multiple fingers close together. The CY8CTMA884 offers all the
benefits users have come to expect from TrueTouch devices,
including 10-finger touch support, low power consumption, grip and
palm rejection, high accuracy, and fast scan times. Cypress’s
large-screen TrueTouch platform expands its leadership position in
small-screen portable electronics – such as handsets and portable
navigation devices – into large-screen portable PC products and
tablets. The devices are in full production today.
Touchscreen Leadership
Cypress’s touch sensing portfolio is the industry’s broadest and
most well adopted, encompassing both TrueTouch and CapSense®
solutions. Cypress is the acknowledged industry leader in touch
sensing. Examples include:
- Cypress was the first to deliver
tracking of unlimited touches.
- Cypress was the first to deliver a true
single-layer sensor solution for capacitive performance at
resistive prices.
- Cypress offers the world’s smallest CSP
packages for important space savings.
- Cypress is still the only company to
offer the patent-pending self and mutual capacitance sensing on the
same chip, enabling the development of advanced features like
waterproofing, support for 1mm stylus, and hover without increased
material or spatial costs.
About TrueTouch
