- General Features
- MIPI DSI is a high-speed interface for embedded displays
- Uses low voltage differential signaling up to 1Gb/s
- Requires fewer pins while maintaining high performance
- Operates at low power and produces minimal EMI
- Interface Structure
- Interface level controls power and speed settings
- Packet level handles image data transmission
- Supports both short (4 bytes) and long (6-65,541 bytes) packets
- Can command up to four peripherals using virtual channel ID
- Operating Modes
- Command mode sends commands to display registers
- Video mode transmits real-time pixel stream
- Video mode requires continuous refresh at 60Hz
- Video mode uses burst or non-burst data transmission methods
- Considerations
- Video mode increases power consumption
- External memory can store frame buffer remotely
- Displays without internal framebuffer are often more cost-effective
- Host processor must provide high-speed data transmission
