The Display Data Channel, or DDC, is a collection of protocols for digital communication between a computer display and a graphics adapter.
DDC (Display Data Channel) is a defined Standard by VESA. While DDC is just the description of the interface, the true data that is exchanged between graphic adapter card and monitor is called EDID (Extended Display Information Data).
Digital Display Interface
The DDIs contain the DisplayPort transport control and other port logic to interface to the DDI physical pins.
The Mobile Industry Processor Interface, also known as MIPI, is a high-speed differential protocol that is commonly used in cellphones. Specifically, the MIPI Display Serial Interface (DSI) technology is designed for display communication.
