Electronic device for displaying content on basis of plurality of scanning rates and operating method therefor

An electronic device comprising:

• a display driver integrated circuit (IC);
• a display;
• memory storing one or more computer programs;
• and
• one or more processors communicatively coupled to the display driver IC, the display, and the memory,
• wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors individually or collectively, cause the electronic device to:
• receive an interrupt from the display driver IC, based on a plurality of scanning rates configured for a plurality of regions of the display,
• identify a portion of the plurality of regions on which content is to be displayed at a first time point at which the interrupt is received, based on the plurality of scanning rates configured for the plurality of regions,
• obtain a plurality of vertical synchronization signals associated with the portion of the plurality of regions, based on the received interrupt,
• obtain content to be displayed on the portion of the plurality of regions, based on the plurality of vertical synchronization signals,
• synthesize a portion of content based on coordinate information of the content, and
• transfer, to the display driver IC, information on a portion of the synthesized content and information on a remaining portion of the synthesized content so that the portion of the synthesized content and the remaining portion of the synthesized content are displayed on the portion of the plurality of regions.
