2 Display Parallel Interface

Display Parallel Interface (DPI) is a digital interface technology that connects source graphics devices to display panels. DPI is parallel, transmitting each color data in an individual pixel on different wires. DPI is simple and low-cost, making DPI designed for applications that require communication between graphics sources and displays.

DPI offers a good data rate, due to the parallel nature, which makes DPI designed for low-resolution display systems. However, DPI also requires more physical connections and wiring than other interfaces, increasing complexity and design footprint. DPI interfaces are commonly used in low-cost panels designed for factory automation and control systems.
