Seiko Epson Corporation (TSE: 6724, “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).

Features of S2D13V70: 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.

“S2D13V70” is compliant with AEC-Q100*2 and operates at temperatures up to 105℃.compliant with AEC Q100*2 and operates at temperatures up to 105℃.

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 trend accelerates,

products that support eDP, which can transfer video signals at higher rates, are growing in popularity in ECUs*3 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。

Safety functions required

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 a blank screen function masks

the display with a particular image pattern when a problem is detected in the transmission path between an ECU and

the conversion IC.

Splitter function

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。

Summary

S2D13V70 contribute developing automotive display system by using advanced ECU(SOC) and

Existing LCD display. It also has safety feature and splitter function. So, it leads to increase

value of customerʼs system. EPSON will keep to development IC products focusing on “high

resolution” and “safety feature” for automotive display system.

Descriptions

※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.

※2 AEC-Q100

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.
