1. An electronic device comprising:
a first display panel configured to detect a touch input;
a driving circuit electrically connected to the first display panel and configured to transfer at least one driving signal for measuring a touch signal to the first display panel; and
a processor operatively connected to the driving circuit,
wherein the processor is configured to:
display a screen by activating a first area which is at least a part of areas of the first display panel;
while the first area is activated, control the driving circuit to measure the touch signal in the first area based on a first touch signal measurement period, wherein the first touch signal measurement period is determined based on a size of the first area;
detect a first event related to a change in an activated area of the first display panel from the first area to a second area;
in response to the first event, change the first touch signal measurement period to a second touch signal measurement period different from the first touch signal measurement period, based on a size of the second area; and
control the driving circuit to measure the touch signal in the second area based on the second touch signal measurement period.
 
14. A method of controlling detection of a touch signal by an electronic device including a first display panel configured to detect a touch input, the method comprising:
displaying a screen by activating a first area which is at least a part of areas of the first display panel;
controlling a driving circuit to measure the touch signal in the first area based on a first touch signal measurement period, wherein the first touch signal measurement period is determined based on a size of the first area;
detecting a first event related to a change in an activated area of the first display panel to from the first area to a second area;
in response to the first event, changing the first touch signal measurement period to a second touch signal measurement period different from the first touch signal measurement period, based on a size of the second area; and
measuring the touch signal in the second area based on the second touch signal measurement period.
