Nuvoton Launches Advanced Automotive Display IC Series Gerda

Nuvoton Introduction of the 4th Generation Gerda Series

Nuvoton Technology Corporation Japan is excited to announce the launch of its new 4th-generation automotive HMI (Human-Machine Interface) display IC series, known as Gerda. This innovative series features three variants: Gerda-4M, Gerda-4L, and Gerda-4C. With advanced capabilities, Nuvoton aims to set a new standard for automotive displays, enhancing safety and driving comfort.

Innovative Features of the Gerda IC Series

The Gerda series introduces remarkable image-processing technology and robust safety functions tailored for modern driving demands. Each variant in the lineup is designed to optimize the driver's experience while ensuring compliance with stringent safety requirements.

Superior Image Processing Engine

A key characteristic of the Gerda-4M variant is its cutting-edge image-processing engine, which significantly improves visibility and comfort in electronic mirrors. This engine effectively addresses common issues found in conventional mirrors, such as glare and visibility loss in low-light or high-contrast conditions. By leveraging a local contrast function, it dynamically adjusts screen contrast based on the surrounding luminance, enabling enhanced visibility even in challenging lighting scenarios.

Advanced AR-HUD Solutions

The Gerda series also caters to augmented reality heads-up displays (AR-HUDs), which must align precisely with both the curvature of the windshield and the driver's line of sight. Utilizing an advanced image-warping engine, the Gerda IC enables remarkable image deformation with minimal latency—making it ideal for this application. Importantly, the dual projection capability of the Gerda series allows it to project both near and far focus images seamlessly with a single chip.

Enhanced Usability and Design

For cluster meters, the Gerda series incorporates a sophisticated 2.5D graphics engine that enriches the user interface by simulating 3D effects using 2D elements. This enhancement not only improves depth perception but also aids drivers in making more accurate, timely decisions. The series provides high-resolution output of WXGA at 60 frames per second, ensuring a modern dashboard experience.

Memory Efficiency

Typically, high-performance HMI solutions necessitate external memory—which can complicate design and increase costs. However, Nuvoton's Gerda Gen-4 series is ingeniously designed with high-speed, high-capacity embedded memory that negates the need for external components. In addition, the Gerda-4L variant features an image compression engine that enables real-time processing while utilizing only half the memory. This allows for the clear display of high-resolution images without the complications of external memory systems.

Robust Safety and Security Features

The Gerda line prioritizes safety with features such as video signal monitoring and alert display monitoring. These systems are essential for ensuring that the designs meet ISO26262 ASIL-B requirements, offering fail-safe operation and real-time monitoring capabilities. Furthermore, the integrated Hardware Security Module (HSM) adheres to the EVITA-Full standard, providing secure over-the-air software updates and a secure boot process, which only permits trusted software to load—thus fortifying against potential cybersecurity threats to vehicles.

Nuvoton’s Commitment to Cybersecurity

As a pioneer in automotive technology, Nuvoton is proud to be the first Japanese company certified under the TUV process of ISO/SAE21434. The company is dedicated to enhancing cybersecurity across its supply chain and continuously upgrades its reliability standards to safeguard both manufacturers and consumers.

Wrap Up and Future Prospects

Nuvoton Technology Corporation Japan is committed to revolutionizing the automotive display landscape with its Gerda series. The integration of advanced technologies not only enhances the driving experience but also emphasizes safety and efficiency, paving the way for the next generation of HMI systems in vehicles.
