Abstract

[Problem] To provide an electronic device that can achieve a large screen exceeding the apparent size limitations of the main unit and display housing, is simple and lightweight, and can be used in confined spaces. [Solution] The display housing 12H is configured to open and close between a stacked state in which the first display unit 21 and the second display unit 22, connected by their respective bent edges 23, are stacked, and an unfolded state in which they are unfolded to form a single surface. It has a flap 25 that is stretched between the first non-display surface 21b of the first display unit 21 and the second non-display surface 22b of the second display unit 22. Depending on the unfolding operation of the first display unit 21 and the second display unit 22, one end 25a of the flap 25 is configured to tilt and slide relative to the first non-display surface 21b, and the other end 25b is configured to tilt relative to the second non-display surface 22b. The first display unit 21 is rectangular, with the side along the connecting edge 12a being the longer side, and the bent edge 23 is along the upper edge opposite the connecting edge 12a.

Claims (3)

  1. An electronic device in which a main housing equipped with an input device and a display housing are rotatably connected to each other by a connecting edge, The display housing is configured to be openable and closable between a stacked state in which the first display section and the second display section, connected by their respective bent edges, are stacked, and an unfolded state in which they are unfolded to form a single surface. The first display unit has a first non-display surface and the second non-display surface of the second display unit has a flap that is stretched between them. In accordance with the deployment operation of the first display unit and the second display unit, one end of the flap is configured to be tiltable and slidable relative to the first non-display surface, and the other end is configured to be tiltable relative to the second non-display surface. The first display section is rectangular, with the longer side being the side along the connecting edge. The electronic device is characterized in that the bent edge is along the upper edge of the first display unit that is opposite to the connecting edge.
  2. In the electronic device described in claim 1, The first display unit and the second display unit are linked to the unfolding operation and have a frame that is displaced relative to the first display unit, The electronic device is characterized in that the frame covers the bent edge to which the first display unit and the second display unit are connected in the stacked state, and covers the end edge facing the bent edge in the unfolded state.
  3. In the electronic device according to claim 2, It has a base portion that can slide relative to the first display portion, The first display unit is rotatably connected to the main body housing by the connecting edge, An electronic device characterized in that the frame and the base portion are integrally formed and displace relative to the first display portion.

Description

This invention relates to an electronic device in which the first and second display sections of a display are configured to be foldable. So-called clamshell-type laptops have a configuration where the main chassis and the display chassis are connected via a hinge, and are generally small and lightweight for portability. Furthermore, because the main chassis and display chassis are the same size, the size of the display is also limited by this configuration, yet there is a demand for even larger screens. Patent Document 1 discloses a retractable display that can be wound onto a predetermined shaft when not in use and unwound when needed. The device described in Patent Document 1 extends so that the display protrudes upward when placed on a tabletop, making it suitable for use in locations where there is limited room for expansion to the left or right.
