Overview

MIPI Display Command Set SM v1.4 (DCS SM v1.4) specifies display functions such as resolution, width and brightness that are transmitted over MIPI Display Serial Interface 2 SM v1.1 (DSI-2SM v1.1). It also supports the Video Electronics Standards Association (VESA®) Display Compression - M (VDC-M) standard.

MIPI DCS v1.4 features include: 

  • A command mode transport mechanism for the VESA VDC-M codec
  • An update of the DCS to include a codec identifier now that DSI-2 and DCS support two different codecs

Implementing the DCS specification reduces the time-to-market and design cost of mobile devices by simplifying the interconnection of products from different manufacturers. In addition, adding new features such as larger or additional displays to mobile devices is simplified due to the extensible nature of MIPI specifications.

MIPI DCS is implemented on either of two physical layers from MIPI Alliance: MIPI C-PHY SM or MIPI D-PHY SM.

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

Note: The specification is available only to MIPI Alliance members. For information about MIPI Alliance membership, visit Join MIPI.
