6 Summary

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, an excellent choice 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 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 display systems.
