3 Display Serial Interface

Display Serial Interface (DSI) is a high-speed serial interface developed by the MIPI Alliance. DSI is commonly used in mobile devices such as smart phones, tablets, and some laptops due to the power efficiency and reduced pin count compared to DPI.

DSI uses differential signaling to transmit data, which enhances noise immunity and allows for longer transmission distances. DSI also supports command mode, allowing the display to remain in standby mode and only update when changes occur, further saving power.

Furthermore, there is a possibility that DSI does not support as high resolution or color depth as LVDS.
