An expandable touch screen display device made up of a flexible display that can be reconfigured from a compact state to a plurality of expanded states. The form factor of the compact state is roughly the size of a typical handheld phone or smaller. The form factor of each of the expanded states is roughly the size of a tablet computer. An internal mechanism is provided for synching the motion of the device’s expansion with the motion of the flexible display’s end plate which provides a force to guide the display around the roller located at the edge of the device.

In one embodiment, a module attached to, situated within, or otherwise associated with the device may contain all or substantially all processing and memory, along with a communications system.

A mobile terminal comprises a body including a first frame and a second frame slidably coupled to a rear surface of the first frame in a first direction or a second direction; a flexible display unit including a front portion located on a front surface of the body, a rear portion located on a rear surface of the body, and a side portion connecting the front portion with the rear portion and surrounding one side of the body; a plurality of reinforcing ribs protruded from a rear surface of the first frame and extended in the first direction; and a plurality of supports protruded from a front surface of the second frame and located between the respective reinforcing ribs. The mobile terminal may enhance usability and portability by varying its size.

A mobile terminal comprises: a body frame that is expandable in a first direction and shrinkable in a second direction; a flexible display in which the area of a display unit positioned on the front surface of the body frame is expanded according to the expansion of the body frame; a driving unit that changes the size of the body; a sensing unit that senses a user command; and a control unit that controls the driving unit to expand or shrink the body frame on the basis of the user command sensed by the sensing unit. Thus, a screen of the display unit positioned on the front surface can be expanded through size adjustment. Because a part of the screen always faces the outside, a separate secondary display unit is not required, and the screen may be expanded step by step as needed.

A mobile terminal according to an embodiment may comprise: a first frame; a second frame which comprises a third rear part provided on the rear surface of the first frame and movable in a first direction and a first roller provided at the end of the third rear part in the first direction; a flexible display panel which is provided to surround the first roller; a driving part for driving the second frame in the first direction or a second direction opposite to the first direction from the first frame; and a side cover which comprises a first plate extending in the second direction from both sides of the first roller and a second plate moving forward and backward on the first plate.

According to various embodiments of the disclosure, an electronic device may include: a housing, a flexible display, and a roller unit. The flexible display may include a first portion, a second portion extending from the first portion in a first direction, and a third portion extending from the second portion. The second portion may be drawn into the inside of a first housing by sliding of a second housing in the first direction when the electronic device is converted from a second state to a first state, and may be drawn out from the inside of the first housing by sliding of the second housing in a second direction opposite to the first direction when the electronic device is converted from the first state to the second state. The third portion may be fixed to a flat region of the third section in the first state.

An electronic device according to various embodiments of the disclosure may include: a first housing including a first conductive portion, a first non-conductive portion, and a first segmented portion extending from the first conductive portion, a second housing configured to accommodate at least a portion of the first housing and to guide a slide movement of the first housing, the second housing including a second conductive portion, and a flexible display including a first area connected to the first housing and a second area extending from the first area and configured to be bendable or rollable, wherein, from a slide-in state to a slide-out state of the first housing with respect to the second housing, the first conductive portion and the second conductive portion may be spaced apart from each other, and in the slide-in state of the first housing with respect to the second housing, at least a portion of the first non-conductive portion may overlap the second conductive portion.

Support structural members, which are used in a flexible display panel. The support structural members comprise a main body support member, which includes a bearing part used for bearing a portion of the flexible display panel; a sliding support member, which is connected to the main body support member in a manner that allows movement along a second direction, the sliding support member includes a first support part and a second support part which are distributed at an interval along a first direction, the first support part being used for extending the main body support member and jointly supporting the flexible display panel with the bearing part; a pushing member, which is connected to the second support part in a manner that allows movement along the second direction, the pushing member includes a stopping part.

A rotation mechanism, includes a middle housing (1), a first support (2) and a second support (3), a first end of the first support is rotatably connected to the middle housing, and a second end of the first support is fixedly connected to a first housing; a first end of the second support is rotatably connected to the middle housing, and a second end of the second support is fixedly connected to a second housing.

According to various embodiments, an electronic device may include a first structure including a first plate including a first face and a second face facing away from the first face, and a second structure including a second plate, which faces the second face of the first plate and has an opening formed therein, and a first side wall extending from a first end portion of the second plate. The first structure may be movable between an open state and a closed state with respect to the second structure in a first direction with respect to the second plate. The second structure may be positioned at a first position from the first side wall when the first structure is in the closed state and positioned at a second distance, which is greater than the first distance, from the first side wall when the first structure is in the open state. The electronic device may further include a flexible touch screen display. The flexible touch screen display may include a planar portion extending across at least part of the first face, mounted to the first face, and having a first width in a second direction perpendicular to the first direction, and a bendable portion extending from the planar portion and positioned from the planar portion to the inside of a space between the first side wall and the first structure when in the closed state. The bendable portion may include a first portion extending from one end of the planar portion and having the same width as the first width, and a second portion extending from the first portion, facing the second plate, and having a second width less than the first width. The second portion of the bendable portion may be exposed visually at least in part to the outside of the electronic device through the opening of the second plate. At least part of the first portion of the bendable portion may be configured to construct substantially the same plane as the planar portion when the first structure transitions from the closed state to the open state. Other various embodiments are possible.
