SYDNEY, 10 December 2019 – Epson has developed a new interface conversion IC for in-vehicle systems that converts eDP (Embedded DisplayPort) video signals to OpenLDI (open LVDS display interface). Samples of the S2D13V70 interface converter are now available. Epson plans to produce 100,000 of these chips per month.
Both eDP and OpenLDI are interface standards for transmitting video signals to displays, but eDP supports higher resolution video and faster speeds than the more widely used OpenLDI.
With the electrification and automation of automobiles, manufacturers will increasingly require higher resolution displays in in-vehicle systems such as instrument clusters and central information displays. As this *1 that control in-vehicle displays. On the other hand, in-vehicle displays that support eDP input are not yet mainstream, and since displays are connected using an OpenLDI interface, eDP output signals from an ECU*1 have to be converted to OpenLDI in the development of in-vehicle systems.
To address this issue in in-vehicle systems development, Epson developed the S2D13V70, an interface conversion IC that supports automotive standards. The new product satisfies the strict quality requirements of the automotive industry. It is compliant with AEC-Q100*2 and operates at temperatures up to 105℃.
The conversion IC is also equipped with safety functions required for automotive systems. For example, a CRC function monitors whether video signals output from an ECU are being properly received, and the IC supports the design of dual-display instrument clusters, with a splitter function that splits and outputs video signals on two displays.
– Automotive standards-compliant eDP to OpenLDI interface conversion IC
– Extensive safety functions (SPI connection, CRC, blank screen)
– Splitter function that enables video of the same resolution up to full-HD to be simultaneously output on two displays
*1 Electronic control unit (ECU)
Any of various units that use electronic circuity to control a system, usually in a vehicle. Numerous ECUs are found in vehicles, where they control systems such as engines, brakes, and car navigation systems.
The Automotive Electronics Council (AEC) is an industry group that creates standards for the reliability and qualification of automotive electronics. It was formed by the “Big Three” U.S. automobile manufacturers in partnership with major electronic component manufacturers. The AEC standard is a de facto global standard that has been widely adopted as a standard for automotive electronic components.

Epson and Elephantech Forge Capital and Business Ties
Sign partnership agreement involving the supply of inkjet printheads
SYDNEY, 10 December 2019 – Epson has agreed to invest in printed electronics startup Elephantech Inc., and the parties have entered into a partnership agreement that includes the supply of inkjet printheads.
Elephantech is a startup that manufactures and sells flexible printed circuits (FPC) manufactured using inkjet printing and electroless copper plating. The company uses a proprietary manufacturing method in which metal materials are printed only on the required areas of a board surface and then grown using plating technology. This method, which is shorter than a conventional lithographic FPC production process, offers benefits in the form of lower environmental impacts, lower manufacturing costs, and shorter lead-times.
One of Epson’s strategies under its Epson 25 Corporate Vision is to accelerate growth by taking maximum advantage of its existing assets and by engaging in collaboration and open innovation. In inkjet, Epson is seeking more open innovation opportunities and is expanding external sales of printheads based on its PrecisionCore technology.
The partnership with Elephantech, which has a large potential customer base, is a specific example of this. Epson expects the collaborative partnership with Elephantech to accelerate the use of inkjet printheads in industrial applications such as printed electronics, a priority area for Epson. Moving forward, Epson will create new markets by aggressively pursuing opportunities to provide inkjet printheads and related information for a wider range of printing applications.
Elephantech, with funding from Epson, is on a mission to make the world sustainable with new manufacturing technologies.
Toward this end, it is expanding its inkjet-printed FPC manufacturing operations and creating markets by developing a broader range of applications for its technology, such as technology for forming wiring patterns on 3D plastic objects and the printing of biomaterials.
Elephantech CEO Shinya Shimizu said, “The environmental impact of global manufacturing continues to grow and is set to exceed the level that the earth can absorb, making it harder and harder to claim sustainability. I believe that additive, inkjet-based manufacturing processes in which material is printed only where it is needed will become the global standard in manufacturing, replacing existing subtractive processes in which material that is not needed is removed and disposed of. We have and will continue to lead a technology revolution toward low-waste manufacturing processes.”
Epson President Minoru Usui said, “We at Epson are committed to playing a central role as an indispensable company in making the world a better place, and toward that end, we are creating new value that can help solve societal challenges and achieve sustainability. Innovations in manufacturing processes using Epson’s inkjet printheads, which have competitive edge in terms of printing performance, environmental performance, and ink compatibility, are a core part of our strategy. The collaboration with Elephantech in printed electronics is an extremely important first step toward reaching our goal of driving innovation in global manufacturing by creating new, more compact, inkjet-based production processes that have a lower environmental impact.”
The investment of capital in Elephantech will have a negligible effect on Epson’s financial results.
