Description

Embodiments of the present invention relate to an electronic device including a foldable flexible plate. As the functional gaps between manufacturers have significantly decreased, electronic devices are gradually becoming slimmer to meet consumer purchasing needs, and improvements are being made to increase the rigidity of electronic devices, enhance their design aspects, and differentiate their functional elements. These electronic devices deviate from a uniform rectangular shape and gradually transform into a variety of shapes. For example, an electronic device has a portable and flexible structure that allows for the use of a large screen display when in use. As part of such electronic devices, foldable electronic devices are constantly being released, and there is a need for improved support structures for foldable displays. A foldable electronic device may include a hinge structure and a first housing structure and a second housing structure connected by the hinge structure in opposing directions. Such a foldable electronic device operates in an in-folding and/or out-folding manner by a hinge structure through which the first housing structure rotates relative to the second housing structure within a range of 0 to 360 degrees. The foldable electronic device includes a flexible display positioned to span across a first housing structure and a second housing structure when opened at 180 degrees. Generally, electronic devices having a single housing (e.g., bar-type electronic devices) are positioned behind the display within the internal space and include at least one flexible plate that can help enhance rigidity by supporting the display and providing noise shielding. Such flexible plates are grounded to the ground of a printed circuit board located inside an electronic device via an electrical connecting member. In the case of a foldable electronic device, a hinge structure allows the first housing structure and the second housing structure to move relative to each other, thereby separating them. Therefore, in the case of flexible plates that cannot be folded, each housing structure is separated and arranged into two flexible plates. In a flexible plate separation structure, frequent folding movements of the electronic device can cause creases to form on the corresponding parts of the display facing the edges of each flexible plate near the hinge structure. Such creases can cause malfunctions in the electronic device and reduce its operational reliability. In the description of the drawings, the same or similar reference numbers are used for identical or similar components.
