Type D HDMI connectors are the micro versions. These are smaller than both standard and mini HDMI connectors, but again retain the same 19-pin configuration (albeit in a slightly different layout due to the size constraints of the microformat).

Type D micro HDMI connectors measure just 5.83mm × 2.20mm, which makes them similar in overall size to a micro-USB connector, and less than half the size of a standard HDMI type A plug or socket. Type D was developed specifically for audio-video connectivity in very small, highly portable devices such as mobile phones.
