摘要
An electronic device comprises a first structure including a first plate providing a first surface and a second surface and a second structure coupled to surround at least a portion of the first structure and configured to guide the first structure in a direction parallel with the first surface or the second surface. The device also includes a roller mounted on an edge of the second structure and a flexible display including a first area mounted on the first surface and a second area extending from the first area. The device also includes at least one support sheet mounted on the roller and wound around the roller as the roller rotates. The support sheet is wound around the roller when the second area is received inside the second structure, and is unfolded inside the second area when the second area is exposed to the outside of the second structure.

This application is based on and claims priority under 35 U.S.C. 119 to Korean Patent Application No. 10-2020-0054347 filed on May 7, 2020 in the Korean Intellectual Property Office, the disclosure of which is herein incorporated by reference in its entirety.
Various embodiments of the disclosure relate to an electronic device, e.g., an electronic device with a flexible display.
As the demand for mobile communication increases, or as the degree of integration of electronic devices increases, the portability of electronic devices such as mobile communication terminals may be increased, and better convenience may be provided in use of multimedia functions. For example, as touchscreen-integrated displays replace traditional mechanical (button-type) keypads, electronic devices may come more compact while functioning as an input device. For example, as the mechanical keypad may be omitted from the electronic device, portability of the electronic device may be improved. As the display area may be expanded to the area which used to be occupied by the mechanical keypad, the electronic device may provide a larger screen while remaining in the same size and weight as when it has the mechanical keypad.

What is claimed is:1. An electronic device, comprising:a flexible display including a first area and a second area extending from the first area; a first structure configured to support the first area of the flexible display; a second structure configured to guide a sliding of the first structure such that the second area of the flexible display is allowed to be received in the second structure and exposed to an outside of the second structure as the first structure is slid; a roller disposed in the second structure; and a support sheet configured to be wound or unwound around the roller, wherein a portion of the second area is configured to be deformed into a curved shape in a position corresponding to the roller and a remaining portion of the second area inserted or received in the second structure while being guided by the roller is configured to be deformed into a flat shape, wherein the support sheet is configured to be separated from the remaining portion of the second area deformed into the flat shape and to be wound around the roller as the second area is received in the second structure such that a gap between the flexible display and the second structure is reduced, and wherein the support sheet is configured to be unwound as the first structure is slid and the second area is exposed to the outside of the second structure such that the gap between the flexible display and the second structure is increased. 2. The electronic device of claim 1 , further comprising:a mounting recess formed in a surface of the roller, wherein a portion of the support sheet is fixed to the mounting recess. 3. The electronic device of claim 1 , further comprising a mounting hole formed from a surface of the roller to an inside of the roller, wherein an end of the support sheet is mounted inside the mounting hole. 4. The electronic device of claim 1 , wherein:a plurality of support sheets are arranged along a direction of a rotation axis of the roller, and each of the plurality of support sheets extends in a direction perpendicular to the rotation axis. 5. The electronic device of claim 1 , wherein:the second area is inserted into an inside of the second structure through a gap between the roller and a second plate included in the second structure. 6. The electronic device of claim 1 , wherein:the second structure further includes:a first side wall perpendicular to a second plate included in the second structure, a second side wall perpendicular to the second plate and the first side wall, and a third side wall perpendicular to the second plate and the first side wall and parallel to the second side wall, the roller is mounted between the second side wall and the third side wall in a position adjacent to an edge of the second plate, and the roller rotates about a rotation axis extending parallel to the first side wall. 7. The electronic device of claim 6 , wherein the flexible display is inserted into an inside of the second structure through a gap between an inner surface of the edge of the second plate and the roller. 8. The electronic device of claim 6 , further comprising:an elastic member mounted on an end of the flexible display and configured to move inside the second structure as the first structure slides, wherein the elastic member slidingly contacts the second plate as the second area gradually moves to a position where the second area is exposed to the outside of the second structure and, when the second area is exposed to the outside of the second structure, the elastic member is positioned between an inner surface of the edge of the second plate and a surface of the flexible display. 9. The electronic device of claim 2 , further comprising:a multi-joint hinge structure including a plurality of rods supporting the second area and connected to the first structure and configured to move over the second structure as the first structure slides, wherein as the first structure slides, a portion of the multi-joint hinge structure is deformed to a curved shape in a position corresponding to the roller. 10.
