Next, FIG. 7 illustrates a portable terminal having first and second display units.

5, a main display unit 151-M is provided on a front surface of a main body of the portable terminal 100 and a front case 100A-1 of the main body of the portable terminal 100 and a rear case 100A- The flexible display unit 151-S of the sub can be extended between the display units 100A-1 and 100A-2.

The user can move the packing part 151e connected to one end of the flexible display part 151 left and right. When the packing part 151e is moved to the right, the sub flexible display part 151-S which is curled in the space formed by the front case 100A-1 and the rear case 100A-2 is unfolded, The portion 151-S has a display area.

At this time, when the sub-flexible display unit 151-S is unfolded, the controller 180 calculates the size of the display area corresponding to the length of the extended sub-flexible display unit 151-S. The control unit 180 causes the object displayed in the display area of the sub flexible display unit 151-S to change in accordance with the degree of extension of the flexible display unit 151, in particular, the extension length.

The sub-flexible display unit 151-S is formed of a material that can be rolled into a space formed between the front case 100A-1 and the rear case 100A-2.

8 to 14, when the shape of the portable terminal is changed due to warping, bending, folding, or the like, according to the present invention, among the plurality of sensors provided in the portable terminal, And on / off operations of the sensors and non-associated sensors associated with the sensor.

8 is a flowchart illustrating a process of controlling the portable terminal according to the present invention.

9 to 14 are explanatory views illustrating a control procedure of the portable terminal according to the present invention.

8 to 14, the controller 180 of the portable terminal 100 controls the flexible display unit 151 such that the flexible display unit 151 is bent, bent, or folded by the user, (S110).

At this time, the first shape may be at least one of a hair band shape, a spectacle glass shape, and a wristwatch shape, as described above.
