MIPI DSI-2SM, initially published in January 2016, supports ultra-high definition (4K and 8k) required by new and future mobile displays. It specifies the physical link between the chip and display in devices such as smartphones, tablets, AR/VR headsets and connected cars.
MIPI DSI-2 v1.1 incorporates the VESA VDC-M and VESA DSC standards in its transport layer. Companies now have the choice of either codec depending on their bandwidth and power requirements.
For a 30-bit image, VDC-M can enable compression down to 6 bits per pixel providing a compression ratio of up to 5:1, while maintaining visually lossless viewing with no attendant loss of bandwidth.
The combination of VESA’s VDC-M and MIPI DSI-2 and MIPI Display Command Set (MIPI DCS) helps systems designers minimize device cost and complexity, maximize battery life and deliver the high-resolution video content that customers seek.
MIPI DSI-2 supports all of the same power-saving features as its predecessor, MIPI DSI, but adds better resilience to electromagnetic interference by introducing data scrambling.
DSI-2 and PHY Compatibility
Although the features of MIPI DSI-2 are quite similar to MIPI DSI, the primary difference is its support for C-PHY. However, it also features backward compatibility with DSI on D-PHY. In addition, because MIPI DSI is a mature, stable specification, future developments will be concentrated on expanding the capabilities of MIPI DSI-2.

MIPI DSI-2 is developed by the MIPI Alliance Display Working Group.
