Interface conversion IC that converts eDP (Embedded DisplayPort) video signals to OpenLDI (open LVDS display interface)

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 trend accelerates, products that support eDP, which can transfer video signals at higher rates, are growing in popularity in ECUs*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.
