Car displays for the instrument cluster and the center console are today’s standard configuration for the higher and middle market segments. Moving from the distributed to the domain computing architecture has many advantages for standalone displays and both interior designers and engineering teams benefit from it. Innovations in the user interface but also new types of displays such as head-up-display and e-mirrors require IC components to support integrated concepts whilst reducing complexity and cost. Our overview of automotive display technology trends highlights the most important ones and outlines how ROHM Semiconductor is part of this development. Last time, we introduced the first six trends: [Link]. In part 2 we present to you six further promising display technology trends:

7. Display interfaces
8. A new serial protocol
9. Ensuring driver’s safety
10. Image analysis is crucial
11. Access to Information – anytime
12. Technology beyond data
7. Display interfaces
Since the resolution of displays is increasing, the bandwidth and speed of the interfaces are also growing. Conventional protocols such as LVDS are limited for high resolutions (above 2K) and do not prove to be cost-effective at system level. ROHM is one of the first companies to offer display ICs for the automotive sector equipped with an eDP (embedded Display Port) interface, whether timing controller (T-CON) or splitter. These can be easily connected to the latest generation of Display SerDes ICs on the market.
Over time, more and more applications have been realized with automotive displays – and innovative ROHM chip solutions inside
Additionally, ROHM offers a complete solution consisting of T-CON and driver ICs for display resolutions beyond 6k and for connection lengths that can reach up to 2m from the driver board to the panel glass. Thus, a so-called Pillar-to-Pillar display – a display that covers the complete width of an automobile cockpit – is easy to realize in the automotive environment.
8. A new serial protocol
A larger diagonal glass increases the link length from a driver board including the T-CON, to each driver IC. ROHM has developed and implemented a high-speed serial protocol to simplify the design and ensure safe transmission of the video signals to the display glass.
In contrast to the proprietary approach of most competitors, ROHM has opened the interface for interested solution providers. Manufacturers of display panels, cables and semiconductors as well as Tier 1 manufacturers, can benefit equally from this ecosystem.
