Cypress Semiconductor Corp. (NASDAQ:CY) today unveiled a
breakthrough feature for its Gen4 TrueTouch® touchscreen
controllers that dramatically improves system performance without
added cost. Cypress has developed a new proprietary technology
based on Gen4’s patent-pending high-voltage Tx drivers. Tx-Boost™
extends Gen4’s performance leadership by delivering three times
higher signal-to-noise ratio (SNR) than previously possible. This
is accomplished without the use of performance-robbing digital
filters or external components, enabling manufacturer’s to produce
the industry’s thinnest handsets and tablets with low material
costs.
The key to excellent touchscreen performance in noisy
environments is high SNR. Gen4 already delivers up to four times
the raw SNR of the competition through its internally generated 10V
Tx circuitry; whereas competitive offerings require customers to
use large, expensive, and noisy external switching regulators to
generate high-voltage Tx signaling. The Tx-Boost feature, now
available on all TrueTouch Gen4 devices, uses specialized hardware
acceleration to triple the already best-in-class SNR of the Gen4
family. This high SNR enables manufacturers to employ
sensor-on-lens with direct lamination to displays and in-cell
architectures with flawless performance for the thinnest products
in the market.
In addition, Tx-Boost efficiently parallelizes multiple
operations in hardware, without burdening the CPU with costly
digital filtering. This significantly increases Gen4’s scan speed,
making the world’s fastest touchscreen controller even faster.
These parallel operations also further improve Gen4’s
industry-leading power consumption by increasing the amount of idle
time during each scan period.
“We understand that touchscreen customers are in highly
competitive markets and need constantly improving technology to
stay ahead,” said Dhwani Vyas, Vice President of Cypress’s User
Interface Business Unit. “We’re pleased to provide Tx-Boost to
enable the industry’s best controller family to extend its
leadership against competitive offerings. Customers who have seen
this technology in action have been universally impressed.”
Availability
The Tx-Boost solution is now available on all Gen4 TrueTouch
devices.
