Kyoto and Espoo, Finland, November 5th ( PRNewswire ) – Nuvoton Technology Corporation Japan ( NTCJ ) and Qt Group (Nasdaq Helsinki: QTCOM ) jointly announced on November 5, 2026, that Nuvoton's Gerda ( TM ) – a HMI controller platform that can provide a high-end graphical user interface without the need for external storage – is now supported as the target hardware for Qt for MCUs.
From car and motorcycle dashboards and head-up displays to home appliance display panels, this combination is capable of meeting the cost requirements of high-volume production while also achieving rich graphics, smooth animations, and responsive touch interactions.
Qt for MCUs boasts a rich component library, an advanced graphics engine, and a flexible development environment that can help developers create visually rich and intuitive user interfaces efficiently ( HMI ). When running on Gerda ( TM ), the high-resolution graphics, smooth animations, and responsive touch interactions provided by Qt for MCUs offer a premium user experience without the need for external storage. As the demand for more complex user experiences in software-defined vehicles increases, storage costs continue to impact system budgets, and over-the-air updates ( OTA ) gradually become an expected feature of connected products, this capability is becoming increasingly important.

The large-capacity built-in RAM of Gerda ( TM ), combined with its rich display, connection, and control interfaces, enables it to build an independent HMI system without the need for external storage. The advanced graphics optimization of Qt and for , in conjunction with the texture compression of Gerda ( TM ), can reduce the memory footprint of the graphical user interface ( GUI ). As a result, there is a smaller number of components and lower total system costs, which is particularly important for high-volume production products.
With the popularization of software-defined vehicles, connected home appliances and two-wheeled vehicles are also following suit. Air-based functions and GUI updates are gradually becoming standards. The development environments for Qt, for, and MCUs , along with the security features of Gerda ( TM ), support safe and efficient updates, allowing developers to modify interfaces and add features even long after the products have been shipped.
Qt for MCUs Integrated development environment, ready-made GUI components, intuitive QML language, simulation, and agentic AI skills contribute to collaboration between design teams and software teams, and simplify the workflow from design to implementation and verification. When combined with Gerda ( TM ), this solution can reduce GUI development complexity, helping teams to build reliable applications in less time and at lower costs.
NTCJ Kim Kuhoi-yeong, Vice President of the Battery and Automotive Division, stated: "The quality of user experience has become a key differentiating factor for modern products. By combining Gerda ( TM ) with Qt for MCUs, customers can enjoy a high-end graphics user experience while balancing performance, memory efficiency, and system costs."
The Michele Rossi Product Management Director of Qt Group stated: "For many years, the choice of microcontrollers has often involved making a trade-off between the interface that users prefer and the system cost that the products can afford. Our efforts are aimed at eliminating this trade-off. By collaborating with Nuvoton, our team can now build the kind of interface that users have been expecting on hardware priced for high-volume production."
