Claim 3:
4. A device implementable in a multi-display apparatus having a primary display and a secondary display, comprising:
a processor configured to execute a status change with respect to the primary display and the secondary display by performing operations comprising:
maintaining a power supplied to the secondary display during the status change; and
switching the primary display and the secondary display from a first state to a second state;

wherein:
in the first state, the primary display is off and the secondary display is on;
in the second state, both the primary display and the secondary display are on; and
in switching the primary display and the secondary display from the first state to the second state, the processor is configured to perform operations comprising:
preparing a backup pipe as a backup of a first virtual pipe with a resolution of the primary display;
changing from the first virtual pipe being connected to a second display serial interface (DSI) corresponding to the secondary display to a second virtual pipe being connected to the second DSI;
connecting the backup pipe to a first DSI corresponding to the primary display;
connecting the second virtual pipe to the second DSI; and
powering on the backup pipe and the first DSI to turn on the primary display,

wherein each of the first virtual pipe and the second virtual pipe comprises respective hardware components configured to provide display processing, overlaying, and picture quality enhancement functionalities.
