Abstract
An electronic device includes a processor configured to generate a slice update map indicating a location of at least one updated slice having a data change in frame data including a plurality of slices; and a display controller configured to extract frame data of the at least one updated slice from a memory based on the slice update map and transfer the frame data to a display driver.
Claims22
An electronic device comprising:
- a processor configured to generate a slice update map indicating a location of at least one updated slice having a data change in frame data comprising a plurality of slices;
- and
- a display controller configured to extract frame data of the at least one updated slice from a memory based on the slice update map and transfer the frame data to a display driver.
An electronic device control method comprising:
- generating a slice update map indicating a location of at least one updated slice having a data change in frame data comprising a plurality of slices;
- extracting frame data of the at least one updated slice from a memory based on the slice update map;
- and
- transferring the frame data to a display driver.

A display driving device comprising:
- a receiver configured to receive a serial transmission signal comprising a first location of a start point of a sub block having a data change, a second location of an end point of the one sub block, and display data having a size of the sub block;
- a frame memory;
- and
- a processor configured to output a current frame stored in the frame memory to a display panel,
- wherein the receiver is configured to update the current frame stored in the frame memory with the display data using the first location and the second location.
