Cypress Announces TrueTouch Advances

November 9, 2011

The single-chip solution for large touchscreens enables direct lamination to sensor-on-lens technology, supporting very thin devices with reduced material costs and fewer fabrication steps.

SAN JOSE, CA /BUSINESS WIRE/ -- Cypress Semiconductor Corp. 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 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 (SNR) 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 in. 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 1 mm stylus, and hover without increased material or spatial costs."

About TrueTouch
Cypress's TrueTouch technology provides the "industry's best noise immunity, highest SNR, fastest refresh rates, lowest power consumption, and world's best accuracy and linearity." The flexible TrueTouch solution allows customers to rapidly develop leading-edge solutions without having to buy turnkey modules. They have a choice of using touch sensors (glass or film) and LCDs from preferred partners, and can develop innovative mechanical designs, ranging from flat to curved surfaces of varying thickness. In addition, TrueTouch devices offer Cypress's legendary noise immunity with patented capacitive sensing technology that enables flawless operation in noisy RF and LCD environments. Additional TrueTouch information is available online.
