MIPI display parallel interface (MIPI-DPI)

The DPI standardizes the interface through a TFT controller. An example is when using a 16

to 24-bit RGB signaling in conjunction with synchronization signals (HSYNC, VSYNC, EN

and LCD_CLK).

The DPI is used to interface with a display without a framebuffer. The pixel data must be

streamed real time to the display.

The real-time performance is excellent, but it requires a high bandwidth in the MCU to feed

the display.

MIPI display serial interface (MIPI-DSI)

In order to decrease the number of lines to interface with a display, the MIPI Alliance has

defined the DSI. The DSI is a high bandwidth multi-lane differential link; it uses standard

MIPI D-PHY for the physical link.

The DSI encapsulates either DBI or DPI signals and transmits them to the D-PHY through

the PPI protocol.

Figure 8 illustrates a MPI-DSI display interfacing example.
