Display method and apparatus for electronic device

An electronic device comprising:

• a display configured to display an image, the display including a main area on a front surface of the electronic device and a sub-area on a side surface of the electronic device;
• a processor configured to process a full resolution image corresponding to the main area and the sub-area, or process a less than full resolution image corresponding to the main area, and transfer, as processed image, the processed full resolution image or the processed less than full resolution image, and control information corresponding to the processed image, to a display control circuit;
• and
• the display control circuit is configured to:
• based on the control information received from the processor, determine whether the processed image corresponds to the processed full resolution image or the processed less than full resolution image,
• based on a determination that the processed image corresponds to the processed full resolution image, transfer the processed full resolution image received from the processor to the display without performing further image processing, and
• based on a determination that the processed image corresponds to the processed less than full resolution image, process a virtual image for the sub-area and transfer the processed less than full resolution image received from the processor and the virtual image to the display.

A display method of an electronic device, the method comprising:

• determining, by a first processor, whether a display scheme is a full resolution image or a less than full resolution image,
• generating, by the first processor, an image for displaying on a display including a flat main area and a curved sub-area and control information based on the determined display scheme,
• providing, by the first processor, the image to a second processor,
• determining, by the second processor, whether the image received from the first processor is a full resolution image or a less than full resolution image,
• based on a determination that the received image corresponds to the full resolution image, transferring, by the second processor, the received full resolution image to the display without performing image processing, and
• based on a determination that the received image corresponds to the less than full resolution image, performing, by the second processor, specific image processing on the received image and then transferring the received image and the processed image to the display.
