Method for sharing screen between devices and device using the same

A method of sharing a screen of a first device with a second device by the first device, the method comprising:

• transmitting information on a first screen displayed on the first device to the second device, in a first connection state in which a same screen is displayed by the first device and the second device;
• switching the first connection state between the first device and the second device into a second connection state;
• and
• transmitting information on a third screen to the second device while the first screen is continuously displayed on the first device, when information requesting that the first screen displayed on the second device be switched into the third screen is received from the second device, in a state in which the first connection state is switched into the second connection state in which an independent screen is displayed by the first device and the second device.

A first device for sharing a screen with a second device, the first device, comprising:

• a sensing unit configured to sense a user input;
• a display unit configured to display a first screen;
• a communication unit configured to transmit information on the first screen displayed on the first device to the second device, in a first connection state in which a same screen is displayed by the first device and the second device;
• and
• a control unit configured to perform a control so that the first screen displayed on the first device is switched into a second screen to be displayed and the first screen is continuously displayed on the second device, when the user input is received through the sensing unit in a state in which the first connection state is switched into a second connection state in which an independent screen is displayed by the first device and the second device.

A first device for sharing a screen with a second device, the first device, comprising:

• a sensing unit configured to sense a user input;
• a display unit configured to display a first screen;
• a communication unit configured to transmit information on the first screen displayed on the first device to the second device, in a first connection state in which a same screen is displayed by the first device and the second device;
• and
• a control unit configured to control the communication unit so that information on a third screen is transmitted to the second device while the first screen is continuously displayed on the first device, when information requesting that the first screen displayed on the second device be switched into the third screen is received from the second device through the communication unit in a state in which the first connection state is switched into a second connection state in which an independent screen is displayed by the first device and the second device.
