  • Publication number: 20220263938
    Abstract: The present disclosure provides a terminal set comprising an extended display and, more specifically, a terminal set having a main body and a sub body fastened to each other in order to solve the problem that multiple displays are output in different directions because a device inclination value measured by a sensor is in a range that has no influence. The terminal set comprises: an inclination sensor mounted on the main body so as to sense the inclination of the main body; and a controller for executing an application and thereby controlling a first display of the main body or a second display of the sub body so as to output the application. If the controller receives a new output signal regarding a first application in a state in which the sensed inclination of the main body is within a screen rotation nonactivation range, the controller retrieves an output rotation value allocated to the first display and an output rotation value allocated to the second display.
