The specific time interval 495 is a time interval that is set to perform switching of screens more smoothly, and the electronic device may constitute the second screen corresponding to the received second source input 450 during the specific time interval 495. For example, even though the second source input is received from the second external device, the second screen may not be constituted immediately at the received time point (e.g., the third time point 473). Accordingly, the electronic device may set an overlap zone in which the second screen may be constituted during the specific time interval 495.
According to various embodiments, the electronic device may output the second screen on a third screen corresponding to the second source input 450 while outputting the third screen on the second screen during the specific time interval 495. For example, the electronic device may output the second screen such that the second screen covers the third screen. Further, the electronic device may apply a fade-out effect such that the third screen appears while the second screen gradually disappears by gradually increasing the transparency of the second screen. The time interval during which the transparency of the second screen is applied may range from the third time point 473 to a fourth time point 474. Further, the time interval during which the transparency of the second screen is applied may range from the second time point 472 to a fourth time point 474.
Thereafter, the electronic device may output the third screen on the display until a fifth time point (t5) 475 at which the reception of the second source input 450 is terminated.
