Touchscreens are a rapidly evolving technology, and the market is quickly shifting to capacitive touch because of its ability to support full multitouch capability, including complex gestures. A capacitive touchscreen detects changes in measured capacitance to determine the location of one or more fingers on the surface of the touchscreen. The capacitive touchscreen consists of a sensor, a touchscreen controller, and a flexible printed circuit (FPC) that connects them all together.

Cypress holds over 100 touch-related patents that cover seven major categories of touchscreen innovation: panel construction, mutual-capacitance sensing, self-capacitance plus mutual-capacitance sensing, scanning methods, finger tracking/ID, noise immunity, and baselining. Our continued leadership in IP ensures that TrueTouch stays at the forefront of emerging touchscreen technology.

DualSense: Self-Capacitance and Mutual-Capacitance Sensing

TrueTouch is the only line of touchscreen controllers that can provide both self and mutual capacitance sensing on the same chip, and switch dynamically between the two in application. Our patented DualSense™ sensing capability (U.S. Patent Nos. 8,358,142; 8,319,505; 8,067,948) gives you the best of both technologies, enabling the development of truly advanced features for touchscreen devices like true waterproofing, passive stylus support, and hover.

Mutual Capacitance
  • Measures capacitance through intersections of horizontal and vertical sensor lines (X times Y)
  • More sensors for higher accuracy and true multitouch capability


Self Capacitance
  • Measures capacitance through individual sensor lines (X plus Y)
  • Stronger signal for greater touch sensitivity without lowering noise threshold
  • Doesn´t support multifinger functionality

Combining self plus mutual capacitance measurement with differential signal analysis in the same device delivers advanced features, like waterproofing, glove capability, passive stylus support, and hover that work in the real world for unbeatable performance.

Sensor Materials & Design

Touchscreen sensors are complex structures. They are built by sputtering indium tin oxide (ITO) onto a glass or PET (plastic film) substrate, and etching away a proprietary pattern into the ITO. The patterns and structures of layers in the sensor vary based on design need, and are custom to that individual system design.

On-stack is a traditional topology, and products are beginning to trend towards SLIM, Sensor-On-Lens, direct lamination, on-cell, or in-cell systems. TrueTouch provides the ultimate design flexibility and system cost reduction with our ability to support all of these sensor materials and stackups. Our controllers can be mounted on either the FPC or the PCB, and have configurable pinouts to suit a variety of needs.

TrueTouch Tools: Simplifying the Design Process

Cypress provides the tools you need to complete a capacitive touchscreen design from concept through mass production. Evaluation kits (EVKs) and development kits (DVKs) allow you to quickly assess solution performance, while manufacturing test kits (MTKs) and programming and debugging tools help you bring designs to production. TrueTouch Host Emulator (TTHE) software enables you to configure and tune your design, and supports all register-configurable TrueTouch products (Gen4 and later products). TrueTouch Driver Android (TTDA) and TrueTouch Driver Windows (TTDW) are software drivers available from Cypress that allows you to integrate your touchscreen design in your end product running an Android or Windows Phone operating system. Cypress touch controllers can interface to the latest processors from Qualcomm, Intel, nVidia, Mediatek, and others through the available software drivers.

TrueTouch Kits

Cypress offers EVKs and DVKs so you can evaluate, prototype, and debug complete designs. Kits are available for each product family to support your design. In addition, we offer MTK to help you test your sensor hardware both in the prototype and mass production phases; and the TT Bridge Development Kit to program and debug hardware and firmware designs. See the table below for quick links to our kits.

TrueTouch Host Emulator Software

Cypress's TrueTouch Host Emulator (TTHE) is a PC-based software application that allows you to design, configure, tune and debug TrueTouch solutions. It reduces design cycle time by eliminating the need to manually compile source code, generate a firmware image and program the device. TTHE supports all register-configurable TrueTouch products. It interfaces with the controller in one of two ways:

  1. TrueTouch Bridge: Hardware that connects a TrueTouch controller on a PCB or an FPC to a host PC running TTHE. This supports prototyping and early stages of development.
  2. Mobile Tuner: Software that connects a TrueTouch-powered end product to a host PC running TTHE, either by USB or wireless connection. This provides a non-intrusive method to configure, tune, and debug TrueTouch controllers in production devices.

TrueTouch Drivers

Cypress's TrueTouch® drivers are easy-to-integrate, high-performance, extensible software drivers that interface between the TrueTouch controller and a touchscreen device's operating system to accurately report touch input. Cypress delivers TrueTouch Driver for Android (TTDA) and TrueTouch Driver for WindowsPhone8 (TTDW). TrueTouch Driver for Android (TTDA) is also part of the Linux Kernel mainline.

TTDA and TTDW allow operating systems to recognize input from advanced features like passive stylus, face detection, and hover.
