Haptic Feedback Capacitive Touch Display Reference Design for Bldg Automation & Medical Applications


Design files


The TIDA-00408 Touch Display with Haptic Feedback reference design showcases haptics for thermostats, building automation, factory automation, point of sale, and automotive applications.  The touch screen provides touch feedback when the user interacts with the on-screen user interface.  The reference design includes a 7” capacitive touch display, one DRV2667 Piezo haptic driver, and two Piezo actuators.

  • Provides Haptic Feedback for On-Screen Touch Controls
  • Uses the DRV2667 Integrated High-Voltage Piezo Driver to Control Piezo Actuators that Produce Tactile Feedback
  • Includes the complete Haptic Subsystem including the Touch Screen, processor, software, and Haptic Driver
  • Detailed mechanical design and assembly
  • Runs Android Operating System with Linux software drivers available for integration
