The MIPI DSI specification has come a long way from the days of its early introduction targeting mainly mobile applications to today, where it is finding use in very different industries like automotive and IoT. This evolution has been further expedited due to the introduction of the C-PHY.
The Display Serial Interface (DSI) is a specification by the Mobile Industry Processor Interface (MIPI) Alliance, which was aimed at reducing the cost of display controllers in a mobile device. It is commonly targeted at LCD and similar display technologies. It defines a serial bus and a communication protocol between the host which is the source of the image data, and the device which is the destination of the image data.
