Abstract: An electronic device is provided. The electronic device includes a deformable display panel, a sensor, a display driving circuit operatively coupled to the deformable display panel and the sensor, and comprising a graphical random access memory (GRAM), and a processor operatively coupled to the display driving circuit and the sensor, wherein the display driving circuit can be configured to, while the size of a displayable area of the deformable display panel is changed, store, in the GRAM, data for displaying an image of a first size received from the processor, receive, from the sensor, a signal for indicating that the size of the displayable area is a second size smaller than the first size, after the data is stored, and scan part of the data in response to the reception of the signal, thereby displaying an image of the second size through the deformable display panel.
