FIG. 2 is a perspective view of a mobile terminal or a portable terminal according to the present invention, as viewed from the front.

The disclosed mobile terminal 100 has a bar-shaped terminal body. However, the present invention is not limited thereto, and can be applied to various structures such as a slide type, a folder type, a swing type, and a swivel type in which two or more bodies are relatively movably coupled.

The body includes a case (a casing, a housing, a cover, and the like) which forms an appearance. In this embodiment, the case may be divided into a front case 101 and a rear case 102. [ A variety of electronic components are embedded in the space formed between the front case 101 and the rear case 102. At least one intermediate case may be additionally 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 display unit 151, the sound output unit 152, the camera 121, the user input units 130/131 and 132, the microphone 122, the interface 170, and the like may be disposed in the front body 101 have.

The display unit 151 occupies most of the main surface of the front case 101. A sound output unit 151 and a camera 121 are disposed in an area adjacent to one end of both ends of the display unit 151 and a user input unit 131 and a microphone 122 are disposed in an area adjacent to the other end. The user input unit 132 and the interface 170 may be disposed on the side surfaces of the front case 101 and the rear case 102. [

The user input unit 130 is operated to receive a command for controlling the operation of the portable terminal 100 and may include a plurality of operation units 131 and 132. The operation units 131 and 132 may be collectively referred to as a manipulating portion and may be employed in any manner as long as the user operates in a tactile manner.

The contents inputted by the first or second operation unit 131 or 132 may be variously set. For example, the first operation unit 131 receives commands such as start, end, scroll, and the like, and the second operation unit 132 controls the size of the sound output from the sound output unit 152 or the size of the sound output from the display unit 151 To the touch recognition mode of the touch screen.

For convenience of explanation, it is assumed that the mobile terminal 100 mentioned below includes at least one of the components shown in FIG. In detail, the mobile terminal 100 according to the present invention may include a display unit 151, a memory 160, and a controller 180.

The display unit 151 provides various visual information to the user, such as an execution screen of an application, a mobile terminal setting screen, and a multimedia content playing screen. The display unit 151 according to the present invention may be implemented as a touch screen. Accordingly, the user may control the operation of the mobile terminal 100 by touching the display unit 151 using a pointer.

The controller 180 may control the display unit 151 to display an auxiliary screen obtained by reducing all or part of the entire screen displayed on the display unit 151. In this case, the displayed auxiliary screen may be displayed as an overlay on the entire screen displayed on the display unit 151.

Since each coordinate constituting the sub screen is stored in the memory 160 in association with each coordinate constituting the full screen, the user controls the operation of the mobile terminal 100 using the sub screen in place of the full screen. can do.

Hereinafter, the coupling relationship of each component will be described in detail through a control flowchart of the mobile terminal.

3 is a control flowchart of a mobile terminal according to an embodiment of the present invention. Referring to FIG. 3, in the displaying of the auxiliary screen (S301), the control unit reduces the whole or part of the entire screen displayed on the display unit or displays the auxiliary screen configured as part of the entire screen on the display unit. In this case, the auxiliary screen may be output as an overlay on the entire screen displayed on the display unit.

4A and 4B are exemplary diagrams for describing a display of an auxiliary screen on a display unit. 4A is an exemplary diagram of a home screen screen of a mobile terminal. As shown in FIG. 4A, the display unit displays a status bar 410 indicating an operation state of the mobile terminal (eg, whether the wireless communication unit is activated, remaining power capacity of the power supply unit, current time, etc.), and Various application icons 422 to 434 may be displayed at the bottom. Furthermore, a widget 440 for displaying weather, calendar, news, stock information, etc. may be further displayed on the home screen screen without running an application.

The user can execute a desired application by touching an icon provided on the home screen screen.

Referring to FIG. 4B, the controller may control the sub screen 450 on which the home screen screen shown in FIG. 4A is reduced to be displayed on the display unit. The sub screen 450 is overlaid on the home screen screen to cover a part of the home screen screen. In order to minimize the visual field limitation of the home screen screen, the controller may control the sub screen 450 to be displayed in a translucent state.

In this case, the auxiliary screen may be initially displayed at a preset position or may be initially displayed in an area selected by the user.

5A to 5C are exemplary diagrams for describing a position where an auxiliary screen is displayed. When the user quickly touches a specific point 504 twice through the pointer 502 on the home screen screen of FIG. 5A, as illustrated in FIG. 5B, the controller may control the auxiliary screen (centering around the point 504 that the user touches). The display unit may be controlled to display 550. Although the auxiliary screen 550 may be fixedly displayed at the initially displayed position, the display position may change based on a user input. For example, the controller may control the sub screen 550 displayed on the lower left side of the display unit to move to the lower right side (see FIG. 5C) based on a user input (see FIG. 5C). In addition, the size of the auxiliary screen may be changed based on a user input.

The auxiliary screen may be a reduction of all or part of the entire screen displayed on the display unit, or may display a part of the entire screen.

6A and 6B are exemplary diagrams for describing an auxiliary screen in which a part of the entire screen is reduced and displayed. 6A and 6B, a relatively small screen (left side of the drawing) is called an auxiliary screen 650, and a relatively large screen (right side of the drawing) is called a full screen 610. As illustrated in FIG. 6A, the sub screen 650 may be displayed by reducing a portion of the entire screen 610 except for the status bar 612.

Alternatively, as illustrated in FIG. 6B, when the entire screen is divided into four sections (622 ˜ 628), the auxiliary screen may display any one of the divided sections. In this case, the controller may control the control key 652 to be displayed together with the auxiliary screen. The controller may control the screen displayed on the sub screen 650 to be changed (eg, 626 to 628) by receiving a user input through the control key 652.

Alternatively, the controller may control the screen displayed on the sub screen to be changed by receiving a user input for flicking the sub screen 650 through the pointer.

Alternatively, the controller may control the sub screen 650 to be scrolled through the pointer so that the remaining parts of the entire screen not displayed on the sub screen may be displayed.

According to another exemplary embodiment of the present disclosure, the controller may control an auxiliary screen composed of icons displayed on the full screen to be overlaid on the full screen.

7 is an exemplary view in which a sub screen composed of icons displayed on a full screen is displayed. The controller may control the sub screen 750 including at least one of the icons 702 ˜ 716 displayed on the full screen 700 to be overlaid on the full screen. The user may control the desired function to be performed by touching an icon displayed on the sub screen 750.

The user may perform an input action for controlling the operation of the terminal through the auxiliary screen. In this case, the controller may derive the coordinates of the entire screen corresponding to the coordinates selected through the user input on the auxiliary screen (S302). Accordingly, even when the user performs a user input through the sub screen, the same effect as the user input through the entire screen may be generated. The correspondence between the coordinates of the sub-screen and the coordinates of the entire screen may be stored in the memory.

8 is an exemplary diagram for describing a correspondence relationship between coordinates of an auxiliary screen and coordinates of an entire screen. In FIG. 8, a relatively small screen (left side of the drawing) is called an auxiliary screen 850, and a relatively large screen (right side of the drawing) is called a full screen 800. For convenience of explanation, it is assumed that the sub-screen 850 and the full screen 800 are divided into 16 sections, and each partition is divided into the first to 16th partitions of the sub-screen 850 and the first screen of the full screen 800. Assume that the first to sixteenth partitions. When the fifth section of the sub-screen 850 is touched by the pointer, the controller may recognize that the fifth section of the entire screen 800 is touched. When the pointer is in contact with the sub-screen 850 and moves the fifth, sixth, and tenth sections in the order of the sub-screen 850, the controller may control the fifth, third, and fifth sections of the full screen 800. It can be recognized that the pointer has moved through the sixth and tenth sections.

However, FIG. 8 is merely an example for explaining that the coordinates of the sub-screen 850 and the coordinates of the entire screen 800 correspond to each other, but are not intended to limit the present invention. As shown in FIG. 8, the sub-screen 850 and the full screen 800 may be divided into n areas so that each area of the sub-screen 850 may match each area of the full screen 800. The auxiliary screen 850 may be associated with the full screen 800 through various methods such as point to point of the auxiliary screen 850 and the full screen 800 through coordinates of the selected point.

In this case, when the coordinates of the entire screen corresponding to the coordinates selected through the user input on the sub screen are the points covered by the sub screen, the controller may control the display unit to display the sub screen, which is displayed as opaque, in a translucent or transparent state. have.

Alternatively, in a state where the subscreen is displayed in a translucent state, when a point covered by the subscreen is selected, the controller may increase the transparency of the subscreen or control the display unit to display the subscreen in a transparent state.

For example, in the example diagram of FIG. 8, it is assumed that the auxiliary screen 850 is displayed overlaid on the ninth section of the full screen 800. In this case, when the sixth, fifth and ninth sections are moved in the order in which the pointer is in contact with the sub-screen 850, the controller may control the sixth, fifth and fifth sections of the entire screen 800. It can be recognized that the pointer has moved through nine sections. In this case, the controller may control the sub screen 850 to be displayed in a translucent or transparent state when the pointer moves to the ninth section of the sub screen 850. In this way, the user may confirm that a user input is applied to a portion of the full screen 800 that is covered by the sub screen 850.

When an event occurs in the mobile terminal while the sub screen is displayed (S303), the controller may display a notification message on the display unit (S304). In this case, when all or part of the notification message is covered by the subscreen (S305), the controller may control the display unit to display the subscreen displayed as opaque in a translucent or transparent state (S306).

Alternatively, when the notification message displayed on the sub screen is displayed while the sub screen is displayed in the translucent state, the controller may increase the transparency of the sub screen or control the display unit to display the sub screen in the transparent state.
