The bulk of the touchscreen market has shifted to projected capacitive touch because of its ability to support multitouch tracking and reporting, and complex gestures. A capacitive touchscreen measures changes in capacitance and processes those measurements 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 multiple categories of touchscreen innovation including 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

Cypress pioneered the mixed use of self and mutual capacitance sensing. 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 at intersections of horizontal and vertical sensor electrodes (X times Y)
  • Per-intersection measurement allows higher reporting 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 a standard or proprietary pattern into the ITO. The patterns and stackup of layers in the sensor vary based on design need, and are often customized to that system design.


On-stack is a traditional sensor construction where the sensor is implemented separate from the display. To improve optical and mechanical characteristics, this separate sensor is often laminated to the display with an optically clear adhesive (OCA). To reduce cost and overall display/sensor thickness, newer products trend towards SLIM, Sensor-On-Lens, on-cell, or in-cell designs. 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.

Evolving to Meet Your Needs as Quickly as They Change

Tap. Swipe. Zoom. Rotate. Type. Different devices can use all, some, or only one of these gestures. But whether you need full multi-finger input or a simple single touch, TrueTouch has the solution. Our platform of single-chip solutions supports a wide range of displays, screen sizes, and applications. We can deliver advanced features for a unique user experience, including glove support, passive stylus capability, face detection, and hover functionality. TrueTouch also supports multiple stackup options for the most flexible and cost-reduced designs, including sensor-on-lens, display integrated, and direct lamination.

We provide more than just a touchscreen controller. With TrueTouch, you get the silicon, software, tools, design, and system-level expertise you need in one convenient package. We provide assisted tuning in our GUI for easy design implementation, as well as development and evaluation kits to assist in your design process (click here to request development and evaluation kits).

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) is a software driver available from Cypress that allows you to integrate your touchscreen design in your end product running an Android 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 the Cypress 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 list below for 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 WiFi-capable production devices.

Prototype and develop solutions with the TrueTouch Bridge via USB

Configure, tune and debug TrueTouch end products with Mobile Tuner via USB or WiFi

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 provides its TrueTouch Driver for Android (TTDA), which is also part of the Linux Kernel mainline.

TTDA allows Android and Linux operating systems to recognize input from advanced features like passive stylus and hover.
