Display device and control method therefor

A control method of a display device, the control method comprising:

• controlling a display of the display device to display a plurality of images in respective areas of the display, based on a plurality of image signals received from a plurality of source devices;
• controlling the display to display an indicator selectively indicating one of the plurality of images according to a first user command;
• receiving a second user command for selecting a first image from among the plurality of images while the indicator is selectively indicating the first image;
• identifying a first source device which provides the first image, from among the plurality of source devices;
• and
• selectively controlling the first source device by:
• transmitting an IR signal for controlling the first source device through a transmitter;
• and
• controlling the display device to transmit a signal to at least one second source device while controlling the display to display the plurality of images in the respective areas of the display, wherein the signal requests the at least one second source device to turn off an IR function.

A non-transitory computer readable recording medium having embodied thereon a program, which when executed by one or more processors of an electronic device, causes the electronic device to execute a method including:

• controlling a display of the electronic device to display a plurality of images in respective areas of the display, based on a plurality of image signals received from a plurality of source devices;
• controlling the display to display an indicator selectively indicating one of the plurality of images according to a first user command;
• receiving a second user command for selecting a first image from among the plurality of images while the indicator is selectively indicating the first image;
• identifying a first source device which provides the first image, from among the plurality of source devices;
• and
• selectively controlling the first source device by:
• transmitting an IR signal for controlling the first source device;
• and
• transmitting a signal to at least one second source device while controlling the display to display the plurality of images in the respective areas of the display, wherein the signal requests the at least one second source device to turn off an IR function.
