Display driving integrated circuit and electronic device having the same

An electronic device comprising:

• a display panel including a plurality of pixels;
• a random access memory (RAM);
• an application processor (AP) connected with the RAM and configured to execute an application;
• a first chip including a first display driving integrated circuit, wherein the first display driving integrated circuit includes a microcontroller unit (MCU) and a graphics memory;
• and
• a second chip including a second display driving integrated circuit, wherein the second chip is connected to the display panel,
• wherein the first chip is configured to receive first image data from the AP and output second image data to the second chip,
• wherein the second display driving integrated circuit includes source drivers, gate drivers, and a timing controller configured to drive the plurality of pixels according to the second image data output by the first chip, wherein the timing controller is further configured to generate a source control signal for controlling an operation timing of the source drivers and a gate control signal for controlling an operation timing of the gate drivers, and
• wherein the MCU is configured to:
• when the AP is in a sleep state, compose the first image data with at least one image stored in the graphics memory based on a control signal received from the AP or post-process the first image data, to generate the second image data, and
• output the second image data to the second chip.
