The system-level chip has two display serial interfaces (Display Serial Interface, DSI): DSI TX0 and DSI TX1. The system-level chip realizes data transmission with the two independent display chips 12 through two MIPI channels.

Of course, the specific target display frame rate synchronization signal can be determined according to the actual selected frame processing mode, and there is no restriction on this.
