MIPI Alliance
The 2025 Electronic Displays Conference was held 12-13 March in Nuremberg, Germany, in conjunction with the Embedded World Conference. The event explores the latest research, knowledge, technologies and market strategies in the world of world of professional displays and applications.
MIPI DSI-2 was the focus of a presentation by MIPI member Introspect Technologies within Session 6: Sustainable Display & Interfaces. The presentation highlights the technical the advantages of DSI-2 at the protocol layer and demonstrates how its simple implementation enables very low latency communication, while offering rich visual experiences.
Session 6: Sustainable Display & Interfaces
Genius in Simplicity: How MIPI DSI-2 Enables Highly Efficient Embedded Display Applications
Mohamed Hafed, Introspect Technology
With more microcontrollers supporting MIPI DSI-2™ as their main display interface, many engineers are attracted to the concept of using cost-effective DSI-2 panels instead of expensive HDMI or DP panels. After all, DSI-2 supports breathtaking resolutions and frame rates with minimal power. However, there is a perception that the DSI-2 physical layers (D-PHY™ and C-PHY™) are not able to drive cabled panels.
The goal of this presentation is to evaluate DSI-2 practically. The presentation shares real measurements illustrating how system implementations can use DSI-2 panels with cables as long as the electrical properties of the specifications are met. It then delves into the advantages of DSI-2 at the protocol layer, showing how its simple implementation enables very low latency communication, while still offering rich visual experiences. The genius in DSI-2 is its simplicity, and this is demonstrated in the context of advanced topics such as variable refresh rates, compression and more.
