摘要： An electronic device is disclosed that includes a display, a display driver IC that drives the display, and at least one processor operationally connected with the display and the display driver IC. The display driver IC moves a display location of one or more pixel data corresponding to an image associated with at least one application from a specified point by a specified distance on an active area of the display. The at least one processor is configured to scale up a first portion of the image by a specified range based on the specified distance, scale down a second portion of the image by the specified range based on the specified distance, and display the image on the active area based on the scaled-up first portion or the scaled-down second portion. In addition, various embodiments recognized through the specification are possible.
