The integration of VESA DSC (3:1 compression) and VDC-M (5–6:1 compression) is critical for 8K video, enabling the bandwidth of a few lanes to be multiplied dramatically without increasing pin count.
The DSI specification defines two primary modes of operation. The choice between them is a major design decision.
Lower display panel cost, but higher power consumption for the host processor. Command Mode
Smartwatches and AR/VR headsets benefit from DSI's low pin count and low power consumption, which allow complex interfaces to be driven by small, space-constrained processors.
