Robust Operational Touch Panel with CAN FD

Overview

Description

As technology advances, consumers expect intuitive, interactive interfaces that enhance the user experience in modern applications like e-bikes and elevators. In these life-critical systems, flawless communication between the operation panel and system controller is essential to ensure reliable, secure operation and deliver the highest levels of safety.

Touch panels with high responsiveness and error-free communication, such as CAN FD, are crucial for safe operation, minimizing the risk of system failure or accidents. This system design offers a highly reliable human machine interface (HMI) with CAN. The touch key technology responds even in wet environments and features haptics to improve operational reliability and provide tactile feedback for users. Additionally, it includes a card authentication function via Near Field Communication (NFC) and supports personal authentication for office and hotel elevators.

System Benefits:

  • Reliable communication between the control panel and system controller via CAN enables quick system response and real-time control, enhancing overall safety.
  • Touch panels and haptics operate reliably even in wet environments, providing enhanced user feedback and improved durability and usability across all operating conditions.
  • User authentication via NFC enables personalized access and enhanced security for scalable designs and applications.
