The body includes a casing (casing, housing, cover, etc.) that forms an exterior. In this embodiment, the case may be divided into a front case 101 and a rear case 102. Various electronic components are built in the space formed between the front case 101 and the rear case 102. At least one intermediate case may be further disposed between the front case 101 and the rear case 102.

The cases may be formed by injecting synthetic resin or may be formed of a metal material, for example, a metal material such as stainless steel (STS) or titanium (Ti).

The terminal body, mainly the front case 101, includes a first display unit 151-1, an audio output unit 152, a camera 121, a user input unit 130/131, 132, a microphone 122, an interface 170, and the like. This can be arranged. In addition, the second display unit 151-2 may be provided to be movable from the side of the terminal body.

The first display unit 151-1 occupies most of the main surface of the front case 101. The audio output unit 152 and the camera 121 are disposed in regions adjacent to one end of both ends of the first display unit 151-1, and the user input unit 131 and the microphone 122 are disposed in the region adjacent to the other end. Is placed. The user input unit 132 and the interface 170 may be disposed on side surfaces of the front case 101 and the rear case 102.

The mobile terminal 100 does not normally expose the second display unit 151-2 to the outside, and receives the user's operation through the user input unit 130 through the second display unit 151-2. It may be exposed to the outside in order to perform a data display operation.

The user selects a key or menu item corresponding to the exposure of the second display unit 151-2, or physically pulls out or unfolds the second display unit 151-2 (when curled into paper), The second display unit 151-2 may be exposed to the outside.

In the display step S410, the mobile terminal 100 may display the same or different data through the first and second display units 151-1 and 151-2, respectively, and the second display unit 151- The electronic paper of the first display unit 151-1 (or the second display unit 151-2) is selected by selecting some data among the data displayed on the electronic paper (or the first display unit 151-1) of 2). } Can also be displayed.

The data displayed in the display step S410 may include an image (for example, a picture, a picture, a captured image, a text image, a web page image, etc.), a data list (for example, a list of incoming / outgoing messages, a picture list, and an e-mail). List, MP3 file list, video list, telephone number list, etc.), a function list including menu items corresponding to functions executable by the mobile terminal 100, and the like.

The mobile terminal 100 detects a user's touch on the electronic paper using a touch sensor (S420).

Here, since the touch sensor and the electronic paper form a mutual layered structure, they can operate as a touch screen.

When the user wants to select some data among the displayed data, the user may touch input a point corresponding to the partial data among the data displayed on the electronic paper.

In the sensing step S420, the mobile terminal 100 may grasp the user's touch and the touch pattern with respect to the electronic paper.

For example, the touch pattern may include a touch count, a touch time, a touch action for setting an area, a drag distance / speed / direction in case of touch drag, and a proximity touch distance / time / speed in case of a proximity touch.

The mobile terminal 100 selects some data from the displayed data to correspond to the touch or touch pattern detected in the sensing step S420 under the control of the controller 180 (S430).

In the selection step S430, the second display unit 151-2 may display a process of selecting the partial data through the electronic paper. Thus, the user can recognize the selection range of some data.

In the selection step S430, the controller 180 may adjust the selection range of the partial data according to the detected touch pattern.

For example, the longer the touch time, the greater the number of touches, the wider the area designated by the touch action, the larger the touch drag distance, the shorter the proximity touch distance, and the selection range of the partial data may be proportional.

The mobile terminal 100 displays some data selected in the selection step S430 through the first display unit 151-1 under the control of the controller 180 (S440).
