Abstract
Description
Electronic device including a display support structure
[0001] Various embodiments of the present disclosure relate to an electronic device including a display support structure.
[0002] Electronic devices are becoming increasingly slimmer, more rigid, and more aesthetically pleasing, while simultaneously improving their functional aspects to differentiate them. Electronic devices are evolving beyond their traditional rectangular form factor and into increasingly diverse shapes. Electronic devices may have a transformable structure that allows for portability while also utilizing large-screen displays. For example, as part of this transformable structure, the electronic device may include foldable housings that fold and unfold relative to each other. Such electronic devices may require a support structure to enhance the durability and / or surface quality of the folding area where the display deforms during the folding and unfolding motions.
[0003] A foldable electronic device may include a hinge device (e.g., a hinge module), and a first housing and a second housing that are foldably connected to each other through the hinge device. The foldable electronic device may be operated in an in-folding and / or out-folding manner by allowing the first housing to rotate relative to the second housing through a specific range of 0 to 360 degrees through the hinge device. The foldable electronic device may include a flexible display (e.g., a display) that is arranged to span the first housing and the second housing when unfolded 180 degrees.
[0004] Foldable electronic devices may be vulnerable to waterproofing due to their folding and unfolding operating mechanisms. Therefore, the electronic devices may include at least one waterproofing member for waterproofing and / or dustproofing against moisture or foreign substances entering the interior. For example, the waterproofing member may include at least one first waterproofing member arranged in a first space of a first housing between the first housing and the flexible display, and at least one second waterproofing member arranged in a second space of a second housing between the second housing and the flexible display. Since these waterproofing members have a height, to compensate for this, the first space and the second space may include a support structure having a specified height arranged between the first waterproofing member and the second waterproofing member.
[0005] However, if such support structures are positioned near at least one waterproofing member at the same height (e.g., thickness), the waterproofing member attached through compression may have an unattached area due to the physical difference in the support structure, which may result in poor waterproofing. Furthermore, if the height of the support structure is applied lower than the waterproofing member in order to resolve the poor waterproofing phenomenon, sagging due to the gap generated between the flexible display and the support structure may cause a deterioration in durability and / or surface quality. Furthermore, it may be difficult to set the height of the support structure considering the compression of the waterproofing member.
[0006] Various embodiments of the present disclosure may provide an electronic device including a display support structure.
[0007] According to various embodiments, an electronic device including a display support structure that can help improve the surface quality or durability of a flexible display can be provided.

According to one embodiment, as illustrated in FIG. 6B, considering the case where the flexible display (400) is attached to the housings (110, 120) through a pressing jig and the waterproof member (481, 484) is pressed, the first height (H1) of the first portion (511) and / or the third portion (521) may be formed to have a height equal to or lower than the height (t1) of the pressed waterproof member (481, 484). According to one embodiment, the flexible display (400) may be attached to the housings (110, 120) through an adhesive member (P). In this case, the first height (H1) of the first part (511) and / or the third part (521) arranged around the waterproof member (481, 484) is formed lower than the height (t1) of the compressed waterproof member (481, 484), so that the repulsive force of the first part (511) and / or the third part (521) is reduced, thereby strengthening the adhesive force of the waterproof member (481, 484) and helping to improve the waterproof performance of the electronic device (100).
[0089] According to various embodiments, the support plate (450) disposed under the display panel (430) may provide flexibility through a plurality of openings (4531). According to one embodiment, the bendable third region (130c) of the flexible display (400) may be provided flexibility based on a folding width (l) disposed to correspond to the plurality of openings (4531) of the support plate (450). According to one embodiment, the folding width (l) may also be determined through a hinge axis distance (p) by a plurality of gears included in the hinge device (140). According to one embodiment, the support width (W) including the second sub-member (510b) of the first member (510), the fourth sub-member (520b) of the second member (520), and the gap between the second sub-member (510b) and the fourth sub-member (520b) may be formed to be equal to or at least greater than the folding width (l) of the support plate (450) and / or the third region (130c). For example, the support width (W) may include the second part (512) of the first member (510) including the first sub-member (510a) and the fourth part (522) of the second member (520) including the fourth sub-member (520b). Accordingly, since the second part (512) and / or the fourth part (522), which are arranged to be relatively thicker than the first part (511) and / or the third part (521), support the part corresponding to the third area (130c) under the display panel (430), the flexible display (400) can be helped to improve durability and surface quality in the third area (130c).
