The choice between DPI, DSI, OLDI/LVDS, and eDP interfaces depends on the specific requirements of a given application. DPI is simple and low-cost, great for lower resolutions but requires more connections. DSI provides power efficiency and reduced pin count, suited for portable devices, but panel choice is limited compared to DPI and OLDI/LVDS. OLDI/LVDS allows for long cable lengths and robust data transmission but requires more power and connections compared to DSI. eDP, and also, offers high efficiency and high-resolution support, making the interface a good fit for embedded systems that require high-quality displays. By understanding these interfaces, designers can select the most appropriate interface for their display systems.
