As used herein, terms used in the present specification are selected from the general terms that are currently widely used, while taking into consideration the functions, but these may vary depending on the intention or custom of the artisan or the emergence of new techniques. Also, in certain cases, there may be a term selected by the applicant at will, in which case the meaning will be described in the description part of the corresponding specification. Therefore, it is intended that the terminology used herein should be interpreted based on the meaning of the term rather than on the name of the term, and on the entire contents of the specification.

1 is a configuration diagram of a display device according to an embodiment of the present invention.

The display device 100 (or the flexible display device) herein may be various types of display devices including the flexible display 110. [ For example, the display device 100 may be a mobile device, a portable device, a digital device, a personal computer, a laptop computer, a tablet computer, or other similar type of display device, including the flexible display 110. When the display device 100 does not require a display function by using the flexible display 110 capable of physical deformation, the display device 100 accommodates the flexible display 110 inside the device, thereby increasing the mobility or portability of the display device 100 .

Referring to FIG. 1, a display device 100 includes a flexible display 110, an extended axis detecting unit 120, an extended length detecting unit 130, and a controller 150. In one embodiment, the display device 100 may further include one or more handle portions 140 as an optional configuration. For example, the display device 100 may further include a first handle and a second handle.

The flexible display 110 refers to a display that can be bent by external pressure to change its shape. Here, bending is a concept including general bending, folding, and rolling. In this case, normal bending means that the flexible display 110 is bent. This general bending differs from folding and rolling in that the bent surfaces do not touch each other. The folding means a state in which the flexible display 110 is folded, and the rolling means a state in which the flexible display 110 is rolled. Rolling may also be defined such that the front and back surfaces of the flexible display 110 are in contact with each other due to bending. In the present specification, these various types of rolling are collectively referred to as rolling.

In one embodiment, the flexible display 110 may be embodied as a plastic substrate (e.g., a polymeric film) that may be deformed by external pressure. Here, the plastic substrate has a structure in which a base film is treated with a barrier coating on both sides. In this case, the base material can be embodied by various resins such as polyimide (PI), polycarbonate (PC), polyethyleneterephtalate (PET), polyethersulfone (PES), polystyrene naphthalate (PEN), and fiber reinforced plastic have. And, the barrier coating is performed on the surfaces facing each other in the base material, and an organic film or an inorganic film can be used to maintain flexibility.

In another embodiment, the flexible display 110 may be embodied as a material having a flexible nature other than a plastic substrate. For example, the flexible display 110 may be embodied as a flexible material such as a thin glass or a metal foil. The flexible display 110 may be embodied as an organic light emitting diode (EL), an electrophoretic display (EPD), an electrochromic display (ECD), a liquid crystal display (LCD), an AMLCD, a plasma display panel It is possible.

The flexible display 110 in this specification may be a flexible display 110 that may be expanded or reduced (e.g., a foldable display, rollable display, etc.) that is expandable or reducible, Can be a rollable display that is rolled-in (or reduced) to be housed inside the housing and roll-out (or expanded) from the interior of the housing to be exposed to the outside . The flexible display 110 may be extended to provide visual information to a user in various display sizes in a state exposed to the outside.

In one embodiment, the flexible display 110 may be a touch sensitive display including a touch sensor. In this case, the display device 100 can detect the touch input of the user touching the surface of the flexible display 110.

The extended axis detecting unit 120 may detect the extended axis of the flexible display 110 and transmit the detection result to the control unit 150. [ Here, the extended axis means an axis on which the flexible display 110 is expanded (e.g., roll-out) or reduced (e.g., roll-in) and includes a horizontal axis or a vertical axis But may include, but is not limited to, axes at various angles. Although the embodiments are described herein with reference to the case where the extension axis includes only the horizontal axis and the vertical axis for convenience of explanation, it should be apparent to those skilled in the art that such description can be applied to the extended axis of various angles, will be.

In one embodiment, the extended axis detecting unit 120 may detect the extended axis of the flexible display 110 using the first sensor. For example, the extended axis detecting unit 120 may sense the direction of the display device 100 or the flexible display 110 using a direction sensor (e.g., a gravity sensor) and detect the extended axis using the detection result, It is possible to detect an extended axis by using a variety of single sensors or sensor combinations. In one embodiment, the first sensor may be located within the handle portion 140.

The extended length detecting unit 130 may detect the extended length of the flexible display 110 and transmit the detection result to the controller 150. Here, the extended length means a length of the flexible display 110 exposed to the outside. At this time, if the extension axis is a horizontal axis, the extension length can be called a horizontal length, and if the extension axis is a vertical axis, the extension length can be called a vertical length.

In one embodiment, the extended length detector 130 may detect the extended length of the flexible display 110 using a second sensor that is different from the first sensor. For example, the extended axis detecting unit 120 may detect the length of the exposed portion of the flexible display 110 using a distance sensor (e.g., a distance measuring sensor) and detect the extended length using the detection result. However, But the extended length can be detected by using various types of single sensors or combinations of sensors. In one embodiment, the second sensor may be located within the handle portion 140.

The handle 140 may be connected to one side of the flexible display 110 to provide storage for the flexible display 110. That is, the grip portion 140 can wind the flexible display 110. In this case, the flexible display 110 can be housed inside the handle 140. For example, the flexible display 110 may be rolled or folded inside the handle 140 to be housed therein. Accordingly, when the user does not use the display function, the user can reduce the volume of the display device 100 by housing the flexible display 110 inside the handle 140.

In one embodiment, the display device 100 includes a first handle coupled to a first side of the flexible display 110 and a second handle coupled to a second side of the flexible display 110 positioned opposite the first side And may include a second handle. When the display device 100 includes a first handle and a second handle, the flexible display 110 may be housed in one or both of the two handle portions 140. [ This will be described in detail below with reference to Fig.

In another embodiment, the display device 100 includes a first handle coupled to a first side of the flexible display 110 and a second handle coupled to a second side of the flexible display 110 positioned opposite the first side It may include an auxiliary handle. In this case, the auxiliary handle does not include a separate input interface or auxiliary display, but can only provide a function that allows the flexible display 110 to be easily pulled out or pushed in from its retracted position.

The control unit 150 may control at least one configuration of the display device 100. For example, More specifically, the control unit 150 controls each of the above-described configurations, and can control data transmission and / or reception between the respective configurations.

In this specification, the control unit 150 can determine an execution mode based on the detected extended axis and the extended length, execute the execution mode, and control the execution screen of the execution mode to be displayed on the flexible display 110. [

In one embodiment, the control unit 150 may determine an application mode corresponding to an extended axis and an extended length as an execution mode. In another embodiment, the controller 150 may acquire an expansion ratio that is a ratio of the current extension length to the maximum extension length based on the extension length, and may determine the application mode corresponding to the expansion axis and the expansion ratio as the execution mode. When the execution mode is determined based on the expansion ratio instead of the extension length, the execution mode can be determined using the mapping information independent of the device. That is, in this case, the display devices 100 having different maximum lengths of the display have the advantage of being able to determine the execution mode according to the expansion ratio of the display by using the same mapping information previously set.

In one embodiment, the application modes corresponding to the extended axis and the extended length may be predefined application modes by the manufacturer or user. In this case, the predefined application can be updated at any time by the user. In another embodiment, the application modes corresponding to the extension axis and extension length may be automatically determined based on factors such as the display size of the externally exposed flexible display 110, available resolution, and user preference.

Hereinafter, the operations of the controller 150 will be described in detail with reference to the drawings. Hereinafter, the control unit 150 may be described as controlling at least one unit included in the display device 100 or the display device 100, and the control unit 150 may be equated with the display device 100 . Further, although not shown in detail in FIG. 1, the configurations of the display device 100 can communicate with each other through one or more buses or signal lines. Further, the configurations of the display device 100 may be implemented by a combination of hardware and software, such as hardware, software, or middleware.

When the flexible display 110 is expanded in the locked state, as shown in the lower part of FIG. 8, the display device can maintain the first execution mode which is the current execution mode. In this case, the display device can continue to display the 1-2 run mode with the expanded display size. In another embodiment, the display apparatus can divide and display the first-second execution mode into the main execution screen and the auxiliary execution screen, as shown in the bottom of FIG. For example, when the first-second execution mode is the camera mode, an execution screen for shooting a camera application is displayed on the main execution screen, and an execution screen on which photographed pictures are displayed on the secondary execution screen. Accordingly, the display device can provide various information to the user by providing the divided execution screen for one application on the expanded screen.
