Accordingly, various functions that are provided through electronic devices are evolving more and more. <CIT> relates to an electronic device and method for displaying and transmitting images thereof. A method for displaying and transmitting images and an electronic device thereof are provided. The electronic device includes a first display, a second display separated from the first display, a transceiver, at least one processor electrically connected to the first display, the second display, and the transceiver, and a memory electrically connected to the at least one processor. The at least one processor is configured to display a first screen image on the first display, provide a second screen image on the second display at least partially simultaneously with the displaying of the first screen image on the first display, provide data associated with one of the screen images to the transceiver, and control the transceiver to transmit the data to an external device such that a screen image at least partially identical to one of the screen images is output on a display of the external device.

Mirroring (which may be referred to herein as a "first mode" for convenience of description) is used to share the screen displayed on an electronic device (e.g., smartphone) by several people. It is also available to enable the screen displayed on a smartphone to be shared by several people or to allow the user of the smartphone to conveniently control the smartphone on a relatively larger screen by displaying a screen with changed attributes (e.g., resolution, number of screens, position of displayed object on the screen, brightness of screen, color of object, shape of object, contrast, or screen size), as displayed on the smartphone, through another display device (this may be referred to herein as a "second mode" or Dex mode" for convenience of description). Various types of electronic devices with a flexible display are recently coming out, but no technical consideration is taken into what screen is being displayed on an electronic device (e.g., smartphone) and an external electronic device (e.g., monitor) when the first mode or second mode is used by the user through the various types of electronic devices. Nor is there any technical consideration as to how a notification event, such as reception of a text message, is handled when the notification event occurs while the user shares the screen with other users through the first mode or second mode.

According to an embodiment of the disclosure, there may be provided a technical consideration as to what screen is being displayed on an electronic device and an external electronic device when the first mode or second mode is provided through various types of electronic devices using a flexible display.

According to an embodiment of the disclosure, there may be provided a technical consideration as to how a generated notification event is processed when the first mode or second mode is provided through various types of electronic devices using a flexible display.
