Description

Electronic device including display support structure {ELECTRONIC DEVICE INCLUDING DISPLAY SUPPORT STRUCTURE}

Various embodiments of this disclosure relate to electronic devices that include a display support structure.

Electronic devices are gradually becoming slimmer, their rigidity is increasing, their design aspects are being strengthened, and their functional elements are being improved to differentiate them. Electronic devices are moving away from the uniform rectangular shape and are gradually being transformed into various shapes. Electronic devices can be convenient to carry and have a deformable structure that can utilize a large screen display. For example, as part of the deformable structure, the electronic device may have a structure (e.g., a rollable structure or can have a slideable structure). These electronic devices may require a support structure that can smoothly support the flexible display even during frequent rolling or sliding operations.

The electronic device may include a rollable electronic device (eg, a slideable electronic device) in which the display area of the display can be expanded and/or reduced. The rollable electronic device is arranged to be supported by a first housing and a second housing, and the first housing and the second housing, which are movably coupled to each other in a manner that is at least partially fitted together, and the slide- It may include a flexible display whose display area varies depending on the in-in or slide-out state. For example, the first housing and the second housing operate to be slidable relative to each other and support at least a portion of a flexible display (e.g., expandable display or stretchable display), thereby maintaining the slide-in state. ), the flexible display can be induced to have a first display area, and in a slide-out state, the flexible display can be induced to have a second display area that is larger than the first display area.

The rollable electronic device may include a plurality of multi-bars attached at specified intervals to the back of the flexible display as a support member for supporting at least a portion of the flexible display when the second housing is moved from the first housing to a specified distance. You can. For example, when the electronic device is in a slide-in state, at least a portion of the flexible display is supported by a support member and is accommodated in the inner space of the first housing or the inner space of the second housing in a bent manner so that it is not visible from the outside. It can be.

However, since only the spaced multi-bars are attached to the back of the flexible display, the rigidity to support the flexible display is insufficient, surface quality deteriorates, and when the flexible display continuously repeats the bending operation, insufficient adhesive area and the flexible display are damaged. The adhesive force with the multi-bar is weakened due to repulsion, which may cause a lifting phenomenon. To improve this, if the thickness of the multi-bars is thickened or the gap between them is narrowed to increase the adhesive area between the multi-bars, the overall weight of the electronic device increases, and the bending that must be responded to when bending the flexible display is reduced, thereby reducing the size of the electronic device. It may cause malfunction. Moreover, the process of attaching a plurality of multi-bars to the back of the flexible display is complicated, which may result in high manufacturing costs.

Various embodiments of the present disclosure can provide an electronic device including a display support structure that can help reinforce rigidity and improve surface quality.

Various embodiments can provide an electronic device including a flexible display and a display support structure that can reduce lifting phenomenon even during frequent operation by providing a sufficient adhesive area.

Various embodiments can provide an electronic device including a display support structure that can help reduce manufacturing costs by improving assembling.

However, the problem to be solved by the present disclosure is not limited to the above-mentioned problems, and may be expanded in various ways without departing from the spirit and scope of the present disclosure.

According to various embodiments, an electronic device includes a first housing, a second housing slidably coupled to the first housing in a first direction, and a flexible display disposed to be supported by the first housing and the second housing. can do. The electronic device may include a support member disposed below the flexible display to support at least a portion of the flexible display. The support member includes an elastic body including a first surface facing the flexible display and a second surface facing in a direction opposite to the first surface, and a plurality of shafts that are at least partially embedded in the elastic body and are spaced apart at predetermined intervals, and include a plurality of shafts. Each of the shafts may be arranged to have a length in a second direction perpendicular to the first direction.

For example, in a state in which the support member 240 is bent, the first curvature (R1) of the first surface (2401) where tensile stress is generated is equal to the second curvature (R2) of the second surface (2402) where compressive stress is generated.

In various embodiments, support member 240 is. When bending, it may be set to have a specified strain rate (e.g., amount of deformation or strain ratio between the first and second surfaces when bending). For example, the support member 240 may be set to have a strain rate in the range of about 300% to 400% depending on the material of the elastic body 241, but when bending the flexible display 230, fatigue due to compression/tension is accumulated. Plastic deformation may occur without restoration to its original state. Plastic deformation of the support member 240 may cause a lifting phenomenon (eg, buckling phenomenon) of the flexible display 230. For example, the support member 240 may be set to have a strain rate of less than 100% when bending. In one embodiment, the support member 240, when bending, has the distance D1 and D2 between each of the plurality of shafts 242, the diameter of the plurality of shafts 242, or the cross section of the plurality of shafts 242.

In some embodiments, when bending, the support member 240 is configured to adjust the first curvature R1 of the outer surface (e.g., first surface 2401) of the elastic body 241 and/or the inner surface (e.g., first surface 2401) of the elastic body 241. The strain may be determined by considering the second curvature (R2) of the second surface (2402). In some embodiments, the maximum spacing D2 of the plurality of shafts 241 may be determined considering the above-described strain rate.
