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. 电容式触控屏包括一个传感器、一个触摸屏控制器和一个将连接起来的柔性印刷电路板 (FPC)。

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.

  • Measures capacitance at intersections of horizontal and vertical sensor electrodes (X times Y)
  • Per-intersection measurement allows higher reporting accuracy and true multitouch capability


  • Measures capacitance through individual sensor lines (X plus Y)
  • 信号更强,触摸灵敏度更佳,且不降低噪声阈值
  • 不支持多点功能



触摸屏传感器结构复杂。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 可提供一流的设计灵活性,并且由于我们可支持所有这些传感器材料和堆叠方式,因此系统成本将会大大降低。我们的控制器可安装到 FPC 或 PCB 上,并可配置引脚,以满足各种需要。


敲击。划动。缩放。旋转。输入。 不同设备可使用全部、某些或其中一种手势。无论您需要完整多点输入还是简单单点触摸,TrueTouch 均可提供完美解决方案。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. 针对最为灵活的经济设计,TrueTouch 还可提供多种堆层选项,其中包括镜头传感器(sensor-on-lens)、集成显示器(display integrated)和直接堆叠(direct lamination)。

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.
