According to an embodiment, the supporting plate 800 may be disposed on the rear side of the flexible display 700. The rear side of the flexible display 700 may indicate a side positioned opposite to a side from which light is emitted from the display panel including a plurality of pixels. The supporting plate 800 may be attached such that, for example, one side of the supporting plate 800 faces the flexible display 700. The supporting plate 800 may contribute to durability of the flexible display 700. The supporting plate 800 may reduce the influence on the flexible display 700 of a load or stress that may occur when the flexible display 700 slides in or slides out. The supporting plate 800 may also help protect the flexible display 700 from being damaged by a force transferred when the first housing (e.g., the first housing 201 of
According to an embodiment, the supporting plate 800 may be formed of various metallic materials and/or non-metallic materials (e.g., polymers). The supporting plate 800 may include, for example, stainless steel. The supporting plate 800 may include, for example, engineering plastic. According to an embodiment, the supporting plate 800 may be implemented integrally with the flexible display 700.
According to an embodiment, the supporting plate 800 may make electronic components (e.g., the supporting structure 900) positioned inside the electronic device 101 substantially invisible from the outside through the flexible display 700.
According to an embodiment, the supporting plate 800 may include a supporting sheet including a touch panel or a pen recognition panel. The touch panel may detect the user's finger gesture input. The touch panel may output a touch event value corresponding to the touched touch signal. The touch panel may be implemented as one from among a capacitive type and a resistive type.

Hereinafter, for convenience of description, it should be noted that the sizes of the second plate area B2 and the supporting structure 900 of the supporting plate 800 are somewhat exaggerated.
According to an embodiment, a plurality of holes or slits 811 may be omitted from the first plate area B1 of the supporting plate 800, but embodiments of the disclosure are not limited thereto.
According to an embodiment, the second plate area B2 of the supporting plate 800 may include a plurality of holes or slits 811. The stretchability (or bending performance) of the second plate area B2 may increase due to the plurality of holes or slits 811 formed in the second plate area B2. The plurality of holes or slits 811 may provide stretchability so that, for example, a portion of the second plate area B2 may be bent when positioned on a portion (e.g., the curved surface 250 of
According to an embodiment, the second plate area B2 of the supporting plate 800 may include a plurality of support areas 820. The support areas 820 may be formed between the stretchable areas 810. The support area 820 may be an area contacted by one of the plurality of bars 910 included in the supporting structure 900. The support area 820 may support the second display area A2 of the flexible display 700 together with the supporting structure 900. For example, a plurality of holes or slits 811 may not be formed in the support area 820. The bar 910 included in the supporting structure 900 may be attached to the support area 820 using an adhesive, but is not limited thereto.
According to an embodiment, each of the plurality of bars 910 may include a first side (e.g., the first side 911 of
Hereinafter, widths (e.g., a first width W1 and a second width W2) of the bar 910 may indicate the size of the bar 910 with respect to a direction (e.g., the left/right direction in the drawings) parallel to the long direction of the supporting plate 800. A length L of the bar 910 may indicate the size of the bar 910 with respect to a direction (e.g., the upper/lower direction in the drawings) parallel to the short direction of the supporting plate 800. The height of the bar 910 (e.g., the height H of
According to an embodiment, at least one bar 910 included in the supporting structure 900 may have a varying width structure. In an embodiment, in at least one bar 910 of the plurality of bars of the supporting structure 900, a first width W1 of a center portion 915 of the at least one bar 910 may be larger than a second width W2 of an end portion 919 of the at least one bar 910. For example, the at least one bar 910 may have a varying width structure in which the width gradually decreases as it approaches the end portion 919 from the center portion 915. Here, the end portion 919 may refer to an end portion of the bar 910 farthest from the center portion 915. For example, the at least one bar 910 may have a symmetrical structure with respect to the center portion 915.
A bar 910 positioned at a location corresponding to a portion (e.g., the curved surface 250) of the electronic device 101 may bend as a repulsive force is applied to it in a radially outward direction of the curved surface 250. The bar 910 may have sufficient rigidity to offset the repulsive force.
A method for securing the rigidity of the bar 910 includes a method of providing a bar 910 that is thick by increasing the height H of the bar 910. When the height H of the bar 910 increases, the size of the battery (e.g., the battery 289 of
Further, in the supporting structure 900 of embodiments of the disclosure, the first width W1 of the center portion 915 of the bar 910 may be increased, and thus the area of the supporting structure 900 in contact with the support area 820 of the supporting plate 800 may be increased. As a result, adhesion between the supporting structure 900 and the supporting plate 800 may be enhanced.
According to an embodiment, the length L of the bar 910 may be longer than the length in the short direction of the supporting plate 800. For example, the end portion 919 of the bar 910 may protrude from the long lateral side 800a of the supporting plate 800. However, according to some embodiments of the disclosure, the end portion 919 of the bar 910 may not necessarily protrude.
According to an embodiment, the support area 820 may have a varying width. Here, the width of the support area 820 may refer to a length measured with respect to the long direction of the supporting plate 800. In the support area 820, for example, a width 821 of the center portion of the support area 820 may be larger than a width 822 of the end portion in the short direction. Here, the center portion of the support area 820 may be a portion corresponding to the center portion 915 of the bar 910.
According to an embodiment, the shape of the support area 820 may correspond to the shape of a surface of one bar 910 among a plurality of bars that is adhered to the support area 820. For example, the shape of the support area 820 may correspond to the shape of the first side 911 of the bar 910. According to an embodiment, the support area 820 may be larger or smaller than the area of the first side 911 of the bar 910.
Corresponding to the varying width of the support area 820, the width of the center portion in the stretchable area 810 may be smaller than the width of the end portion in the short direction. In a portion of the supporting plate 800 that corresponds to a portion (e.g., the curved surface 250) of the electronic device 101, stress due to bending may be greatest at the outer side in the short direction. Therefore, the stretchable area 810 with a sufficient width may be provided to ensure stretchability at the outer side in the short direction, where the most stress is generated. The center portion in which relatively less stress is generated may have a small width to increase the width of the support area 820.

The terms as used herein are provided merely to describe some example embodiments of the disclosure, but are not intended to limit the disclosure. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. As used herein, each of such phrases as “A or B,” “at least one of A and B,” “at least one of A or B,” “A, B, or C,” “at least one of A, B, and C,” and “at least one of A, B, or C,” may include all possible combinations of the items enumerated together in a corresponding one of the phrases. As used herein, the term “and/or” should be understood as encompassing any and all possible combinations by one or more of the enumerated items. As used herein, the terms “include,” “have,” and “comprise” are used merely to designate the presence of the feature, component, part, or a combination thereof described herein, but use of the terms does not exclude the likelihood of presence or adding one or more other features, components, parts, or combinations thereof. As used herein, the terms “first” and “second” may modify various components regardless of importance and/or order and are used to distinguish a component from another without limiting the components.
As used herein, the terms “configured to” may be interchangeably used with the terms “suitable for,” “having the capacity to,” “designed to,” “adapted to,” “made to,” or “capable of” depending on circumstances. The term “configured to” does not essentially mean “specifically designed in hardware to.” Rather, the term “configured to” may mean that a device can perform an operation together with another device or parts. For example, a “device configured (or set) to perform A, B, and C” may be a dedicated device to perform the corresponding operation or may mean a general-purpose device capable of various operations including the corresponding operation.
Meanwhile, the terms “upper side,” “lower side,” and “front and rear directions” used in the disclosure are defined with respect to the drawings, and the shape and position of each component are not limited by these terms.
In the disclosure, the above-described description has been made mainly of example embodiments, but the disclosure is not limited to such specific example embodiments. Instead, the disclosure includes all various modifications, equivalents, and/or substitutes of the various example embodiments.
