MIPI DSI is an interface that can provide dynamic graphics and high resolutions. Maximum color depths at fast communication speeds are accessible over differential data lines to render images and videos to the display. MIPI DSI displays have become a popular choice because they support high quality graphics with fewer pin connections.

Large amounts of pixel data are used to create the colorful and defined images. The data is stored in a memory location called the frame buffer. The frame buffer must be provided by the display or by the processor. The MIPI DSI interface offers an alternative by operating the display in video mode.

This resource will discuss the options for storing large amounts of image data and the operating modes available in the MIPI DSI communication protocol. There are two modes available when memory is accessible to the display. The modes are differentiated by the location of frame buffer provided for display data. The substitute for display memory is to operate the display in video mode which does not require memory access. Considerations of memory location and access should be made when using the MIPI DSI protocol.

The location of the frame buffer memory is dependent on what is available and what can be accessed at a speed compliant with the MIPI DSI interface. The MIPI DSI display interface requires high speed memory access to prevent flickering and tearing on the display. Each location of memory has its own benefits and constraints. The display memory can be stored in the following locations for the MIPI DSI interface.

The MIPI DSI protocol communicates at high speeds of up to 1Gb/s for 2-data lane interfaces. The location of RAM will need to be accessed by the MPU and forwarded to the display at a speed fast enough to meet minimum interface requirements.

The MIPI DSI displays have an embedded controller IC that can be used to format pixel data. The display IC’s come in versions with and without display data RAM (DDRAM). Display modules without internal RAM are lower in price and more common in DSI displays. The memory will have to be provided externally or different methods of operation can be implemented.

The MIPI DSI protocol has two operation modes. The command mode is used when the display has access to the internal frame buffer memory. The display controller receives commands from the processor and then formats the data to store in the frame buffer for the next display refresh.

MIPI DSI displays that contain internal RAM can operate in command and adapted command modes where display data sent to and controlled internally. This reduces the CPU required from the microprocessor because the display handles the memory and image processing. This reduces the potential bandwidth limitations on the MPU.

The MIPI DSI protocol offers two modes: command and video. The video mode is used when the display does not have access to internal RAM. The video mode sends the data from the processor to the display in a continuous stream. The MPU is required to stream the data which increases the bandwidth of the system processor.

In video mode, the processor sends the packets of display data through the high speed MIPI DSI link. The high-speed data is transmitted in long packets structured by synchronization signals to specify horizontal and vertical timings. The display data is streamed in this sequence at a continuous refresh rate.

The video mode of the MIPI DSI protocol relies on internal RAM to be provided by the host processor. It is used when the display does not provide internal display RAM or if the display does not have an internal controller. The synchronization event can be sent in brief low power operation events or as null data events. These events also structure the begin and end of a DSI data packet.

The video mode of the MIPI DSI communication protocol consumes more power than the low power command mode. The high-speed video mode can incorporate low power transition times between lines or frames to conserve power while synchronizing the display data. The low power modes indicate the begin and end flags of packet data.

The MIPI DSI video mode will be used to send external RAM continuously to the display. This will increase the required MPU frequency to retrieve and send display data to and from RAM. Processor memory is not sacrificed when implementing an external memory to store the frame buffer.

MIPI DSI has been widely adopted. It is ubiquitous in smartphones and also being used in tablets, laptops and laptop/tablet hybrids. It is also being implemented by the automotive industry for dashboard displays and in-car infotainment systems, and used in wearables, IoT and virtual/augmented reality applications.

MIPI DSI operates on the MIPI D-PHY physical layer. It uses a command set defined in the MIPI Display Command Set (MIPI DCS). It also incorporates the Display Stream Compression (DSC) Standard from the Video Electronics Standards Association (VESA). Overall, the feature set of MIPI DSI is quite similar to that of the more recent MIPI DSI-2℠ specification, which offers support for both MIPI D-PHY℠ and MIPI C-PHY℠.
