[0082] Embodiments supported by the present disclosure are more fully described herein with reference to the accompanying drawings, in which one or more example embodiments are shown. However, aspects supported by the present disclosure may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these example embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the example aspects of the present utility model to those skilled in the art.

[0083] Terms such as, for example, first and second may be used to describe various components, but these components should not be limited by these terms. These terms used herein may distinguish one component from other components and are not limited by these terms. For example, without departing from the scope of the present disclosure, the first component may be referred to as the second component, and similarly, the second component may also be referred to as the first component. Unless otherwise stated, terms in the singular form may include the plural form.

[0084] The terms used herein are for the purpose of describing particular embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, as used herein, "a", "one (kind / er)", "the (said / this)", and "at least one (kind / er)" do not denote a limitation of quantity and are intended to include both the singular and the plural. Unless the context clearly indicates otherwise, for example, "an element (a element)" has the same meaning as "at least one element". "At least one (kind / er)" will not be construed as limiting "a" or "one (kind / er)". "Or" means "and / or". As used herein, the term "and / or" includes any combination and all combinations of one or more of the related listed items. It will also be understood that when used in this specification, the terms "comprises and / or comprising" or "includes and / or including" specify the presence of the stated features, regions, wholes, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, regions, wholes, steps, operations, elements, components, and / or groups thereof.

[0085] Taking into account the measurements under discussion and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system), the terms "about" or "approximate" as used herein include the stated value and include the range of suitable deviations for a particular value as determined by a person of ordinary skill in the art. For example, the term "about" can mean within one or more standard deviations, or within ±30%, ±20%, ±10%, or ±5% of the stated value.

[0086] Taking into account the measurements under discussion and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system), the "about" or "approximate" as used herein includes the stated value and means within the range of acceptable deviations for a particular value as determined by a person of ordinary skill in the art. For example, "about" can mean within one or more standard deviations, or within ±30%, ±20%, ±10%, or ±5% of the stated value.

[0087] As used herein, the term "substantially" means approximate or virtually equal (e.g., within a threshold percentage of an equivalent). As used herein, the term "substantially simultaneous" means approximate or virtually simultaneous (e.g., within a threshold percentage of an equivalent). As used herein, the term "substantially the same" means approximate or virtually the same (e.g., within a threshold difference).

[0088] For ease of description, spatial relative terms such as "under", "below", "lower", "above", and "upper" may be used herein to describe the relationship of one element or feature to another element(s) or feature(s) as shown in the figures. It will be understood that the spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device is flipped in the figures, an element described as "under" or "below" another element or feature will then be oriented "above" the other element or feature. Thus, the term "under" can encompass both an upper and a lower orientation. The device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatial relative terms used herein are to be interpreted accordingly.

[0089] Embodiments are described herein with reference to cross-sectional illustrations that are schematic illustrations of idealized embodiments. Accordingly, variations in the shapes of the illustrations due to, for example, manufacturing techniques and / or tolerances are to be expected. Thus, the embodiments described herein should not be construed as limited to the particular shapes of regions shown herein, but include deviations in shapes due to, for example, manufacturing. For example, regions shown or described as flat will typically have rough and / or non-linear features. Additionally, sharp corners shown may be rounded. Thus, the regions shown in the figures are schematic in nature, and their shapes are not intended to show the exact shape of a region and are not intended to limit the scope of the claims.

[0090] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It will also be understood that terms, such as those defined in a general dictionary, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and this disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

[0091] It should be appreciated that the various embodiments of the present disclosure and the terms used herein are not intended to limit the technical features set forth herein to particular embodiments, and include various changes, equivalents, or alternatives of the corresponding embodiments. Regarding the description of the drawings, like reference numerals may be used to refer to like or related elements. It will be understood that, unless the relevant context clearly indicates otherwise, the singular form of a noun corresponding to an item may include one or more things. As used herein, each of such phrases as "A or B," "at least one of A and B," "A, B, or C," and "at least one of A, B, and C" may include any one or all possible combinations of the items enumerated in the respective phrase.

[0092] It will be understood that if an element (e.g., a first element) is referred to as "coupled to," "coupled with," "connected to," or "connected with" another element (e.g., a second element), with or without the terms "operatively" or "communicatively," this means that the element can be directly (e.g., wired), wirelessly coupled to the other element or coupled to the other element through a third element.

[0093] Hereinafter, example embodiments of the present disclosure will be described with reference to the drawings.

[0094] Figure 1 is a plan view of a display device 10 according to an embodiment of the present disclosure. Figure 2 is for showing Figure 1 an unfolded state view of a display panel PNL.Figure 3 is a cross-sectional view of the display device 10 taken along line I-I' as viewed in the direction indicated by the arrow. Figure 1

[0095] The display device 10 according to an embodiment may be a sliding display device 10 or a slidable display device 10 that can slide. In some embodiments, the display device 10 may be (but is not limited to) a unidirectional slidable display device 10 that can slide in one direction (e.g., a first direction DR1 and a direction opposite to the first direction DR1) (also referred to herein as a single-slideable display device 10). For example, the display device 10 according to some embodiments may be a multi-directional slidable display device 10 that can slide in multiple directions (e.g., a first direction DR1 and a direction opposite to the first direction DR1, and a second direction DR2 and a direction opposite to the second direction DR2) (also referred to herein as a multi-slidable display device 10). The following description will focus on the single-slideable display device 10, but aspects of the present disclosure are not limited thereto.

[0096] As Figures 1 to 3 shown, the display device 10 according to the embodiments described herein may include a display panel PNL, a first support plate 201, a second support plate 202, a first main guide rail MGR1, a second main guide rail MGR2, a first auxiliary guide rail AGR1, and a second auxiliary guide rail AGR2.

[0097] The display panel PNL may display an image therein. Embodiments of the present disclosure support using any suitable type of display panel as the display panel PNL, such as, for example, an organic light-emitting display panel including an organic light-emitting layer, a micro light-emitting diode (LED) display panel using micro light-emitting diodes, a quantum dot light-emitting diode display panel using a quantum dot light-emitting layer including quantum dots, and an inorganic light-emitting display panel using an inorganic light-emitting element including an inorganic semiconductor.

[0098] The display panel PNL may be a flexible panel. The display panel PNL may have flexibility such that the display panel PNL can be partially curled, bent, or flexed along the first main guide rail MGR1 and the second main guide rail MGR2. The display panel PNL can slide in the first direction DR1 and the direction opposite to the first direction DR1 (referred to herein as the first opposite direction).

[0099] The outer surface of the display panel PNL (e.g., Figure 1 ​The surface shown in can be a surface for displaying an image. In some embodiments, the inner surface of the display panel PNL can face the first support plate 201. The inner surface of the display panel PNL can be disposed opposite to the outer surface of the display panel PNL. The inner surface and the outer surface of the first support plate 201, which will be described later, can be disposed on opposite sides of each other, and the outer surface and the inner surface of the second support plate 202 can be disposed on opposite sides of each other.

[0100] The area of the display region of the display panel PNL can vary based on whether the display device 10 is slid open or closed. For example, when the display device 10 is closed or not slid open (hereinafter referred to as the first state or the closed state), the display panel PNL can have a first display region DA1 with a first area. In an example where the display device 10 is slid open (hereinafter referred to as the second state or the open state (expanded state)), in addition to the first display region DA1, the display region can further include an expanded second display region DA2. In some aspects, the area of the display region in the second state can vary based on the degree of sliding of the display device 10. For example, as the degree of sliding of the display device 10 increases, the area of the display region in the second state can increase. In other words, the area of the display region of the display panel PNL can vary based on the state of the display device 10. In the open state, the area of the display region of the display panel PNL can vary based on the degree of the open state (e.g., the amount by which the display device 10 is slid open).

[0101] The display panel PNL can be disposed on the outer surface of the first support plate 201. The display panel PNL can be attached to the outer surface of the first support plate 201. For example, the inner surface of the display panel PNL can be attached to the outer surface of the first support plate 201. The display panel PNL can be fixed to the first support plate 201. The first support plate 201 can be formed of a flexible material that can be bent.

[0102] The second support plate 202 can be disposed on the inner surface of the first support plate 201. The second support plate 202 can be attached to the inner surface of the first support plate 201. For example, the outer surface of the second support plate 202 can be attached to the inner surface of the first support plate 201. The second support plate 202 can be fixed to the first support plate 201. The second support plate 202 can be formed of a flexible material that can be bent.

[0103] A plurality of drive members 100a and 100b may be disposed on the inner surface of the second support plate 202. For example, the plurality of drive members 100a and 100b may be disposed on the second support plate 202 such that the plurality of drive members 100a and 100b are equally spaced from each other in the first direction DR1. The plurality of drive members 100a and 100b may be arranged parallel to each other. The plurality of drive members 100a and 100b may be attached to the inner surface of the first support plate 201. The plurality of drive members 100a and 100b may be fixed to the first support plate 201.

[0104] The first main guide rail MGR1 may be disposed on one side of the display panel PNL.

[0105] The second main guide rail MGR2 may be disposed on the opposite side of the display panel PNL. In other words, the second main guide rail MGR2 may be disposed opposite to the first main guide rail MGR1 (e.g., disposed on the opposite side of the first main guide rail MGR1). For example, the first main guide rail MGR1 and the second main guide rail MGR2 may be disposed on opposite sides of each other in the second direction DR2. In some aspects, the first main guide rail MGR1 and the second main guide rail MGR2 may face away from each other in the second direction DR2. Optionally, the first main guide rail MGR1 and the second main guide rail MGR2 may face each other in the second direction DR2.

[0106] As Figure 3 shown, the first auxiliary guide rail AGR1 and the second auxiliary guide rail AGR2 may be disposed between the first main guide rail MGR1 and the second main guide rail MGR2. The first auxiliary guide rail AGR1 may be disposed opposite to the second auxiliary guide rail AGR2 (e.g., disposed on the opposite side of the second auxiliary guide rail AGR2). The first auxiliary guide rail AGR1 may be disposed adjacent to the first main guide rail MGR1, and the second auxiliary guide rail AGR2 may be disposed adjacent to the second main guide rail MGR2.

[0107] As Figure 3 shown, the plurality of drive members 100a and 100b may be disposed between the first main guide rail MGR1 and the second main guide rail MGR2.

[0108] The drive members 100a and 100b may be movably coupled to one of the first main guide rail MGR1 and the second main guide rail MGR2. In some aspects, the drive members 100a and 100b may be movably coupled to the first auxiliary guide rail AGR1 and the second auxiliary guide rail AGR2.

Figure 5 is Figure 4 a cross-sectional view of the first main guide rail MGR1 in the display device 10.Figure 6 is Figure 5 a first enlarged view of region AA of Figure 7 is Figure 6 a side view of region AA shown in Figure 8 is Figure 5 a second enlarged view of region AA of

[0110] Figure 9 is a plan view of a plurality of drive members 100a and 100b and a second support plate 202 according to an embodiment of Figure 5

[0111] In the first enlarged view shown in Figure 6 a first auxiliary guide rail AGR1 among a plurality of elements of region AA of Figure 5 is not shown so as not to interfere with the description herein. In the second enlarged view shown in Figure 8 a first main guide rail MGR1 and a coupler among a plurality of elements of region AA of Figure 5 are not shown so as not to interfere with the description herein.

[0112] As shown in Figure 4 the first main guide rail MGR1 may be disposed on one side of the display panel PNL. The first main guide rail MGR1 may have an elliptical shape. Although not shown in Figure 4 the second main guide rail MGR2 may have the same configuration as the first main guide rail MGR1. For example, the second main guide rail MGR2 may have an elliptical shape that is the same as or substantially the same as the elliptical shape of the first main guide rail MGR1.

[0113] As shown in Figure 3 , Figure 5 , Figure 6 , Figure 7 and Figure 9 a plurality of drive members 100a and 100b may be coupled to one of the first main guide rail MGR1 and the second main guide rail MGR2. In other words, a plurality of drive members 100a and 100b may be movably coupled to one of the first main guide rail MGR1 and the second main guide rail MGR2. For example, a plurality of drive members 100a and 100b may move in the first main guide rail MGR1 and the second main guide rail MGR2.

[0114] As shown in Figure 3 and Figure 9 each of the drive members 100a and 100b may have a rod shape extending in the second direction DR2.

[0115] Each of the driving members 100a and 100b can be selectively coupled to one of the first main guide rail MGR1 and the second main guide rail MGR2, and not coupled to the other of the first main guide rail MGR1 and the second main guide rail MGR2. For example, each of the driving members 100a and 100b can be selectively coupled to one of the first main guide rail MGR1 and the second main guide rail MGR2 (e.g., only one of the first main guide rail MGR1 and the second main guide rail MGR2). In an example, the first driving member 100a can be coupled to the first main guide rail MGR1, and the second driving member 100b can be coupled to the second main guide rail MGR2, wherein the driving members arranged in the odd rows (or even rows) are defined as the first driving member 100a relative to the first direction DR1, and the driving members arranged in the even rows (or odd rows) are defined as the second driving member 100b relative to the first direction DR1. The first driving member 100a and the second driving member 100b can be alternately arranged. In other words, a plurality of first driving members 100a and a plurality of second driving members 100b can be alternately arranged.

[0116] In some aspects, as Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 9 shown, a plurality of driving members 100a and 100b can be movably connected to the first auxiliary guide rail AGR1 and the second auxiliary guide rail AGR2. For example, each of the plurality of first driving members 100a can be movably coupled to the first auxiliary guide rail AGR1 and the second auxiliary guide rail AGR2, and each of the plurality of second driving members 100b can be movably coupled to the first auxiliary guide rail AGR1 and the second auxiliary guide rail AGR2.

[0117] As Figure 3 、 Figure 5 、 Figure 8 and Figure 9 shown, the first auxiliary guide rail AGR1 can include a first guide rail R11 and a second guide rail R12 that face each other and are spaced apart from each other. The guide hole GHa can be located between the first guide rail R11 and the second guide rail R12. For example, the first guide rail R11 and the second guide rail R12 can define the guide hole GHa.

[0118] As Figure 3 、 Figure 5 、 Figure 8 and Figure 9As shown, the second auxiliary guide rail AGR2 may include a first guide rail R21 and a second guide rail R22 that face each other and are spaced apart from each other. The guide hole GHb may be located between the first guide rail R21 and the second guide rail R22. For example, the first guide rail R21 and the second guide rail R22 may define the guide hole GHb. The configuration of the second auxiliary guide rail AGR2 may be the same as or substantially the same as the configuration of the first auxiliary guide rail AGR1 described herein.

[0119] Each of the drive members 100a and 100b may be coupled to the first auxiliary guide rail AGR1 and the second auxiliary guide rail AGR2. For example, each of the drive members 100a and 100b may be coupled to the guide hole GHa of the first auxiliary guide rail AGR1 and the guide hole GHb of the second auxiliary guide rail AGR2.

[0120] As described herein, each of the drive members 100a and 100b is coupled to the first main guide rail MGR1 or the second main guide rail MGR2, and may also be coupled to the first auxiliary guide rail AGR1 and the second auxiliary guide rail AGR2. For example, the first drive member 100a may be coupled to the first main guide rail MGR1, the first auxiliary guide rail AGR1, and the second auxiliary guide rail AGR2. In an example, the second drive member 100b may be coupled to the second main guide rail MGR2, the first auxiliary guide rail AGR1, and the second auxiliary guide rail AGR2.

[0121] As Figure 9 shown, the first drive member 100a may include a rod 110a, a main coupler 120a, a first auxiliary coupler 131a, and a second auxiliary coupler 132a.

[0122] The rod 110a of the first drive member 100a may have a rod shape extending in the second direction DR2.

[0123] The main coupler 120a of the first drive member 100a may be provided at one end of the rod 110a. The main coupler 120a of the first drive member 100a may be coupled to the first main guide rail MGR1.

[0124] The first auxiliary coupler 131a of the first driving member 100a may be disposed on the rod 110a such that the first auxiliary coupler 131a is adjacent to one end of the first driving member 100a (or the main coupler 120a). For example, the first auxiliary coupler 131a of the first driving member 100a may be disposed on the rod 110a between one end of the rod 110a (or the main coupler 120a) and the center of the rod 110a. One end and the other end of the rod 110a of the first driving member 100a may be disposed on opposite sides of each other. For example, one end of the rod 110a of the first driving member 100a may be disposed adjacent to the first main guide rail MGR1, and the other end of the rod 110a of the first driving member 100a may be disposed adjacent to the second main guide rail MGR2.

[0125] The second auxiliary coupler 132a of the first driving member 100a may be disposed on the rod 110a such that the second auxiliary coupler 132a is adjacent to the other end of the first driving member 100a. For example, the second auxiliary coupler 132a of the first driving member 100a may be disposed on the rod 110a between the other end of the rod 110a and the center of the rod 110a.

[0126] The rod 110a, the main coupler 120a, the first auxiliary coupler 131a, and the second auxiliary coupler 132a of the first driving member 100a may be formed integrally.

[0127] As Figure 9 shown, the second driving member 100b may include a rod 110b, a main coupler 120b, a first auxiliary coupler 131b, and a second auxiliary coupler 132b.

[0128] The rod 110b of the second driving member 100b may have a rod shape extending in the second direction DR2.

[0129] The main coupler 120b of the second driving member 100b may be disposed at the other end of the rod 110b. The main coupler 120b of the second driving member 100b may be coupled to the second main guide rail MGR2.

[0130] The first auxiliary coupler 131b of the second driving member 100b may be disposed on the rod 110b such that the first auxiliary coupler 131b is adjacent to one end of the second driving member 100b. For example, the first auxiliary coupler 131b of the second driving member 100b may be disposed on the rod 110b between one end of the rod 110b and the center of the rod 110b. One end and the other end of the rod 110b of the second driving member 100b may be disposed on opposite sides of each other. For example, one end of the rod 110b of the second driving member 100b may be disposed adjacent to the first main guide rail MGR1, and the other end of the rod 110a of the second driving member 100b may be disposed adjacent to the second main guide rail MGR2.

[0131] The second auxiliary coupler 132b of the second driving member 100b may be disposed on the rod 110b such that the second auxiliary coupler 132b is adjacent to the other end (or the main coupler 120b) of the second driving member 100b. For example, the second auxiliary coupler 132b of the second driving member 100b may be disposed on the rod 110b between the other end (or the main coupler 120b) of the rod 110b and the center of the rod 110b.

[0132] The rod 110b, the main coupler 120b, the first auxiliary coupler 131b, and the second auxiliary coupler 132b of the second driving member 100b may be formed integrally.

[0133] According to the embodiments described herein, the first main guide rail MGR1 may include a straight portion and a curved portion as shown in Figure 7 , and the thickness of the straight portion may be different from the thickness of the curved portion. For example, the thickness of the curved portion may be greater than the thickness of the straight portion. Optionally, the thickness of the straight portion may be equal to the thickness of the curved portion.

[0134] In some embodiments, the characteristics of the second main guide rail MGR2 may be the same as or substantially the same as the characteristics of the first main guide rail MGR1. For example, the second main guide rail MGR2 may include a straight portion and a curved portion, and the thickness of the straight portion may be different from the thickness of the curved portion. For example, the thickness of the curved portion may be greater than the thickness of the straight portion. Optionally, the thickness of the straight portion may be equal to the thickness of the curved portion.

[0136] As shown in Figure 10As shown in the figure, the first driving member 100a may include a rod 110a, a main coupler 120a, a first auxiliary coupler 131a, and a second auxiliary coupler 132a.

[0137] As Figure 11 shown in the figure and described herein, the main coupler 120a of the first driving member 100a may be provided at one end of the rod 110a. The main coupler 120a of the first driving member 100a may include a first protrusion 121a, a second protrusion 122a, and a connecting member 123a. The main coupler 120a may have, for example, a rectangular cross-section or a circular cross-section.

[0138] The first protrusion 121a of the first driving member 100a (see Figure 10 ) may protrude from the rod 110a. For example, the first protrusion 121a may protrude in a direction opposite to the second direction DR2 (hereinafter referred to as the second opposite direction).

[0139] The second protrusion 122a of the first driving member 100a may face the first protrusion 121a. The second protrusion 122a may protrude in the second opposite direction. The second protrusion 122a may be arranged parallel to the first protrusion 121a. The first main guide rail MGR1 (see Figure 9 ) may be provided between the first protrusion 121a and the second protrusion 122a of the first driving member 100a. In other words, the first driving member 100a may be coupled to the first main guide rail MGR1 through the first protrusion 121a and the second protrusion 122a of the main coupler 120a. In an example where the first driving member 100a is coupled to the first main guide rail MGR1, the first protrusion 121a of the first driving member 100a may face the outer surface (or outer peripheral surface) of the first main guide rail MGR1, and the second protrusion 122a of the first driving member 100a may face the inner surface (or inner peripheral surface) of the first main guide rail MGR1.

[0140] The connecting member 123a of the first driving member 100a may connect the first protrusion 121a and the second protrusion 122a. The connecting member 123a may protrude from the first protrusion 121a in the third direction DR3. The connecting member 123a may be provided between the first protrusion 121a and the second protrusion 122a. One side of the connecting member 123a may be connected to the first protrusion 121a, and the opposite side of the connecting member 123a may be connected to the second protrusion 122a. The first protrusion 121a, the second protrusion 122a, and the connecting member 123a may be formed integrally.

[0141] The main coupler 120a including the first protrusion 121a, the second protrusion 122a, and the connecting member 123a may have, for example, a C shape or a U shape.

[0142] As shown Figure 11 in FIG. 3, the first auxiliary coupler 131a of the first driving member 100a may include a support member 1311a and a locking means 1312a.

[0143] The support member 1311a of the first auxiliary coupler 131a of the first driving member 100a may protrude from the upper surface of the rod 110a in the third direction DR3. The upper surface of the rod 110a may face away from the lower surface of the rod 110a, and the lower surface of the rod 110a may face the second support plate 202 described herein (see Figure 3 ). In other words, the upper surface of the rod 110a may be the side of the rod 110a provided on the opposite side of the second support plate 202.

[0144] The locking means 1312a of the first auxiliary coupler 131a of the first driving member 100a may be provided on the support member 1311a of the first auxiliary coupler 131a. The dimension of the locking means 1312a in the second direction DR2 may be greater than the dimension of the support member 1311a in the second direction DR2, such that both ends of the locking means 1312a are not supported by the support member 1311a. That is, for example, the locking means 1312a may be formed such that both ends of the locking means 1312a are in indirect contact with the support member 1311a (e.g., via the central portion of the locking means 1312a in indirect contact with the support member 1311a). Therefore, a space may be formed between one end of the locking means 1312a and the upper surface of the rod 110a (e.g., in the third direction DR3), and a space may be formed between the opposite end of the locking means 1312a and the upper surface of the rod 110a (e.g., in the third direction DR3). The support member 1311a and the locking means 1312a (also referred to herein as the engaging portion) may be formed integrally. The locking means 1312a of the first auxiliary coupler 131a of the first driving member 100a may be embedded in the guiding hole GHa (see Figure 3 ) of the first auxiliary guide rail AGR1 (see Figure 3 ). In an example where the first auxiliary coupler 131a is coupled to the guiding hole GHa of the first auxiliary guide rail AGR1, both ends of the locking means 1312a may respectively face the inner surface (or inner circumferential surface) of the first guide rail R11 (see Figure 3 ) of the first auxiliary guide rail AGR1 and the inner surface (or inner circumferential surface) of the second guide rail R12 (see Figure 3 ) of the first auxiliary guide rail AGR1.

[0145] The first auxiliary coupler 131a of the first driving member 100a including the support member 1311a and the locking means 1312a may have, for example, a T shape.

[0146] AsFigure 12 As shown in FIG. 1 , the first driving member 100a (see Figure 10 The second auxiliary coupler 132a of the first drive member 100a may include a support member 1321a and a locking device 1322a. The second auxiliary coupler 132a of the first drive member 100a may be the same as the first auxiliary coupler 131a of the first drive member 100a described herein (see Figure 11 ) have substantially the same configuration, and redundant description will be omitted. The locking device 1322a of the second auxiliary coupler 132a of the first driving member 100a may be embedded in the second auxiliary guide rail AGR2 (see Figure 3 ) of the guide hole GHb (see Figure 3 In the example where the second auxiliary coupler 132a is coupled to the guide hole GHb of the second auxiliary guide rail AGR2, both ends of the locking device 1322a of the second auxiliary coupler 132a may respectively face the first guide rail R21 of the second auxiliary guide rail AGR2 (see Figure 3 ) and the inner surface (or inner peripheral surface) of the second guide rail R22 (see Figure 3 )'s inner surface (or inner peripheral surface).

[0147] like Figure 12 As shown in FIG. 1 , the third protrusion 333a may be provided at the other end of the first driving member 100a. The third protrusion 333a may protrude from the other end of the first driving member 100a in the second direction DR2. The third protrusion 333a of the first driving member 100a may face the second main rail MGR2 (see FIG. 1 ). Figure 9 )'s outer surface (or peripheral surface).

[0149] like Figure 13 As shown in FIG. 1 , the second drive member 100 b may include a rod 110 b , a main coupler 120 b , a first auxiliary coupler 131 b and a second auxiliary coupler 132 b .

[0150] The main coupler 120b of the second drive member 100b may be disposed at one end of the rod 110b (as described herein, also referred to herein as the other end of the rod 110b).

[0151] The first protrusion 121b of the second driving member 100b can protrude from the rod 110b. For example, the first protrusion 121b can protrude in the second direction DR2.

[0152] The second protrusion 122b of the second driving member 100b can face the first protrusion 121b. The second protrusion 122b can protrude in the second direction DR2. The second protrusion 122b can be arranged parallel to the first protrusion 121b. The second main guide rail MGR2 (see Figure 9 ) can be provided between the first protrusion 121b and the second protrusion 122b of the second driving member 100b. In other words, the second driving member 100b can be coupled to the second main guide rail MGR2 through the first protrusion 121b and the second protrusion 122b of the main coupler 120b. In an example where the second driving member 100b is coupled to the second main guide rail MGR2, the first protrusion 121b of the second driving member 100b can face the outer surface (or outer peripheral surface) of the second main guide rail MGR2, and the second protrusion 122b of the second driving member 100b can face the inner surface (or inner peripheral surface) of the second main guide rail MGR2.

[0153] The connecting member 123b of the second driving member 100b can connect the first protrusion 121b and the second protrusion 122b. The connecting member 123b can protrude from the first protrusion 121b in the third direction DR3. The connecting member 123b can be provided between the first protrusion 121b and the second protrusion 122b. One side of the connecting member 123b can be connected to the first protrusion 121b, and the opposite side of the connecting member 123b can be connected to the second protrusion 122b. The first protrusion 121b, the second protrusion 122b, and the connecting member 123b can be formed integrally.

[0154] The main coupler 120b including the first protrusion 121b, the second protrusion 122b, and the connecting member 123b can have, for example, a C shape or a U shape.

[0155] As Figure 14 shown, the second auxiliary coupler 132b of the second driving member 100b can include a support member 1311b and a locking device 1312b. The second auxiliary coupler 132b of the second driving member 100b is substantially the same as the first auxiliary coupler 131a of the first driving member 100a described herein, and redundant descriptions will be omitted.

[0156] As Figure 15 shown, the second driving member 100b (see Figure 13) The first auxiliary coupler 131b of the second driving member 100b may include a support member 1321b and a locking device 1322b. The first auxiliary coupler 131b of the second driving member 100b is substantially the same as the second auxiliary coupler 132a of the first driving member 100a described herein, and redundant descriptions will be omitted.

[0157] In some aspects, as Figure 15 shown, a third protrusion 333b may be provided at one end of the second driving member 100b. The third protrusion 333b may protrude from one end of the second driving member 100b in a second opposite direction. The third protrusion 333b of the second driving member 100b may face the outer surface (or outer peripheral surface) of the first main guide rail MGR1 (see Figure 9 ). The third protrusion 333b of the second driving member 100b may be substantially the same as the third protrusion 333a (see Figure 10 ) of the first driving member 100a described herein (see Figure 10 ), and redundant descriptions will be omitted.

[0158] It should be noted that the embodiments of the present disclosure support changing the number and position of the auxiliary couplers 131a, 132a, 131b, and 132b in various ways to support the display device 10.

[0159] Figure 16 is a plan view of a plurality of driving members 100a and 100b and a second support plate 202 according to an embodiment.

[0160] Figure 16 The display device 10 (see Figure 1 ) may include aspects of the display device 10 described herein, and for the sake of brevity, repeated descriptions of the same elements are omitted. Figure 16 The display device 10 of Figure 9 differs from the display device 10 (see Figure 1 ) in that the auxiliary couplers and the auxiliary guide rails are provided at different positions. The following description will focus on the differences between the display device 10 of Figure 16 and the display device 10 of Figure 9 .

[0161] As Figure 16 shown, for each of the first driving member 100a and the second driving member 100b, the auxiliary coupler 130a of each first driving member 100a may be provided at the center of the rod 110a of the first driving member 100a, and the auxiliary coupler 130b of each second driving member 100b may be provided at the center of the rod 110b of the second driving member 100b.

[0162] The auxiliary couplers 130a of the first drive member 100a and the auxiliary couplers 130b of the second drive member 100b may be arranged in a row along the first direction DR1. In Figure 16 In the example shown, the auxiliary couplers 130a of the first drive member 100a and the auxiliary couplers 130b of the second drive member 100b may be arranged in a row along the first direction DR1.

[0163] Thus, for example, the auxiliary guide rail AGR may be positioned at the center of the plurality of drive members 100a and 100b.

[0164] Figure 16 Each of the auxiliary couplers 130a and 130b may have the same configuration as the Figure 9 first auxiliary coupler 131a described herein, and Figure 16 the auxiliary guide rail AGR may have the same configuration as the Figure 9 first auxiliary guide rail AGR1 described herein. The first guide rail R1 and the second guide rail R2 of the auxiliary guide rail AGR may be the same as the first guide rail R11 and the second guide rail R12 of the first auxiliary guide rail AGR1 shown in Figure 9 respectively.

[0182] As Figure 20 and Figure 21 shown, the first driving member 100a may include a first sub-driving member 100aS1 and a second sub-driving member 100aS2 that are separated from each other.

[0183] The first sub-driving member 100aS1 may be coupled to the first main guide rail MGR1. For example, one side of the first sub-driving member 100aS1 may be coupled to the first main guide rail MGR1.

[0184] The first sub-driving member 100aS1 may include a first rod 110aS1 and a first main coupler 120aS1.

[0185] The first main coupler 120aS1 of the first sub-driving member 100aS1 may be provided at one end of the first rod 110aS1. The first main coupler 120aS1 of the first sub-driving member 100aS1 may be coupled to the first main guide rail MGR1.

[0186] As Figure 21 and Figure 22 shown, the first main coupler 120aS1 of the first sub-driving member 100aS1 may include a first protrusion 121aS1, a second protrusion 122aS1, and a connecting member 123aS1.

[0187] The first protrusion 121aS1 of the first sub-driving member 100aS1 may protrude from the first rod 110aS1. For example, the first protrusion 121aS1 may protrude in a second opposite direction.

[0188] The second protrusion 122aS1 of the first sub-driving member 100aS1 may face the first protrusion 121aS1. The second protrusion 122aS1 may protrude in a second opposite direction. The second protrusion 122aS1 may be arranged parallel to the first protrusion 121aS1. The first main guide rail MGR1 (see Figure 20 ) may be provided between the first protrusion 121aS1 and the second protrusion 122aS1 of the first sub-driving member 100aS1. In other words, the first sub-driving member 100aS1 may be coupled to the first main guide rail MGR1 through the first protrusion 121aS1 and the second protrusion 122aS1 of the first main coupler 120aS1. In an example where the first sub-driving member 100aS1 is coupled to the first main guide rail MGR1, the first protrusion 121aS1 of the first sub-driving member 100aS1 may face the outer surface (or outer peripheral surface) of the first main guide rail MGR1, and the second protrusion 122aS1 of the first sub-driving member 100aS1 may face the inner surface (or inner peripheral surface) of the first main guide rail MGR1.

[0189] The connecting member 123aS1 of the first sub-driving member 100aS1 can connect the first protrusion 121aS1 and the second protrusion 122aS1. The connecting member 123aS1 can protrude from the first protrusion 121aS1 in the third direction DR3. The connecting member 123aS1 can be disposed between the first protrusion 121aS1 and the second protrusion 122aS1. One side of the connecting member 123aS1 can be connected to the first protrusion 121aS1, and the opposite side of the connecting member 123aS1 can be connected to the second protrusion 122aS1. The first protrusion 121aS1, the second protrusion 122aS1, and the connecting member 123aS1 can be formed integrally.

[0190] The first main coupler 120aS1 including the first protrusion 121aS1, the second protrusion 122aS1, and the connecting member 123aS1 can have, for example, a C shape or a U shape.

[0191] As Figure 20 , Figure 21 and Figure 23 shown in, the second sub-driving member 100aS2 can be coupled to the second main guide rail MGR2. For example, one side of the second sub-driving member 100aS2 can be coupled to the second main guide rail MGR2.

[0192] The second sub-driving member 100aS2 can include a second rod 110aS2 and a second main coupler 120aS2.

[0193] The second main coupler 120aS2 of the second sub-driving member 100aS2 can be disposed at one end of the second rod 110aS2. The second main coupler 120aS2 of the second sub-driving member 100aS2 can be coupled to the second main guide rail MGR2.

[0194] As Figure 21 and Figure 23 shown in, the second main coupler 120aS2 of the second sub-driving member 100aS2 can include a first protrusion 121aS2, a second protrusion 122aS2, and a connecting member 123aS2.

[0195] The first protrusion 121aS2 of the second sub-driving member 100aS2 can protrude from the second rod 110aS2. For example, the first protrusion 121aS2 can protrude in the second direction DR2.

[0196] The second protrusion 122aS2 of the second sub-driving member 100aS2 can face the first protrusion 121aS2. The second protrusion 122aS2 can protrude in the second direction DR2. The second protrusion 122aS2 can be parallel to the first protrusion 121aS2. The second main guide rail MGR2 (see Figure 20) It can be disposed between the first protrusion 121aS2 and the second protrusion 122aS2 of the second sub-driving member 100aS2. In other words, the second sub-driving member 100aS2 can be coupled to the second main guide rail MGR2 through the first protrusion 121aS2 and the second protrusion 122aS2 of the second main coupler 120aS2. In an example where the second sub-driving member 100aS2 is coupled to the second main guide rail MGR2, the first protrusion 121aS2 of the second sub-driving member 100aS2 can face the outer surface (or outer peripheral surface) of the second main guide rail MGR2, and the second protrusion 122aS2 of the second sub-driving member 100aS2 can face the inner surface (or inner peripheral surface) of the second main guide rail MGR2.

[0197] The connecting member 123aS2 of the second sub-driving member 100aS2 can connect the first protrusion 121aS2 and the second protrusion 122aS2. The connecting member 123aS2 can protrude from the first protrusion 121aS2 in the third direction DR3. The connecting member 123aS2 can be disposed between the first protrusion 121aS2 and the second protrusion 122aS2. One side of the connecting member 123aS2 can be connected to the first protrusion 121aS2, and the opposite side of the connecting member 123aS2 can be connected to the second protrusion 122aS2. The first protrusion 121aS2, the second protrusion 122aS2, and the connecting member 123aS2 can be formed integrally.

[0198] The second main coupler 120aS2 including the first protrusion 121aS2, the second protrusion 122aS2, and the connecting member 123aS2 can have, for example, a C shape or a U shape.

[0199] The opposite ends of the first sub-driving member 100aS1 of the first driving member 100a and the opposite ends of the second sub-driving member 100aS2 of the first driving member 100a can face each other. For example, the opposite ends of the first sub-driving member 100aS1 and the opposite ends of the second sub-driving member 100aS2 can face each other in the second direction DR2.

[0200] It should be noted that Figure 20 the second driving member 100b of Figure 20 can have the same structure as the first driving member 100a of

[0201] In some aspects, according to an embodiment,Figure 20 The second driving member 100b of Figure 9 and Figure 16 and Figure 17 has the same structure or substantially the same structure as the second driving member 100b of

[0202] Figure 24 is a plan view of a plurality of driving members 100a and 100b and a second support plate 202 according to an embodiment.

[0203] Figure 24 The display device 10 of Figure 1 (see Figure 24 may include aspects of the display device 10 described herein, and for the sake of brevity, repeated descriptions of the same elements are omitted. Figure 20 The display device 10 of Figure 1 (see Figure 24 ) is different from the display device 10 of Figure 24 in that the display device 10 of Figure 20 further includes a first auxiliary coupler 131aS1 and a second auxiliary coupler 132aS2. The following description will focus on the differences between the display device 10 of

[0204] As shown in Figure 24 , the first sub-driving member 100aS1 of the first driving member 100a may further include a first auxiliary coupler 131aS1, and the second sub-driving member 100aS2 of the first driving member 100a may further include a second auxiliary coupler 132aS2. That is, for example, each of the plurality of first sub-driving members 100aS1 may include a first auxiliary coupler 131aS1, and each of the plurality of second sub-driving members 100aS2 may include a second auxiliary coupler 132aS2.

[0205] Figure 24 The first auxiliary coupler 131aS1 and the second auxiliary coupler 132aS2 of Figure 19 may be the same as the first auxiliary coupler 131a and the second auxiliary coupler 132a described herein, respectively.

[0206] It should be noted that Figure 24 the second driving member 100b of Figure 24The first driving member 100a has the same structure. For example, the first sub-driving member 100bS1 of the second driving member 100b may further include a first auxiliary coupler 131bS1, and the second sub-driving member 100bS2 of the second driving member 100b may further include a second auxiliary coupler 132bS2. That is, for example, each of the plurality of first sub-driving members 100bS1 may include a first auxiliary coupler 131bS1, and each of the plurality of second sub-driving members 100bS2 may include a second auxiliary coupler 132bS2.

[0207] In some aspects, according to an embodiment, Figure 24 the second driving member 100b of Figure 9 , Figure 16 , Figure 17 and Figure 20 has the same structure as the second driving member 100b of

[0208] Figure 25 is a view for showing the unfolded state of the display panel PNL of Figure 5 .

[0209] As Figure 25 shows, when the display device 10 is slid open or is being slid open (e.g., partially open or fully open) (i.e., the display device 10 is in the second state), in addition to the first display area DA1, the display area may further include an unfolded second display area DA2.

[0210] In some embodiments, as Figure 25 shows, the first driving member 100a moves counterclockwise along the first main guide rail MGR1, the first auxiliary guide rail AGR1, and the second auxiliary guide rail AGR2 (see Figure 3 ). In some aspects, although not shown in the drawings, the second driving member 100b (see Figure 3 ) may move counterclockwise along the second main guide rail MGR2 (see Figure 3 ), the first auxiliary guide rail AGR1, and the second auxiliary guide rail AGR2.

[0211] In other words, when the first driving member 100a and the second driving member 100b move counterclockwise along the first main guide rail MGR1 (or the second main guide rail MGR2), the first auxiliary guide rail AGR1, and the second auxiliary guide rail AGR2, the display area of the display panel PNL can be unfolded.

[0212] In the display device according to the embodiments described herein, since one of the driving members 100a or 100b is selectively coupled to one of the two main guide rails MGR1 and MGR2 (e.g., only one of the two main guide rails MGR1 and MGR2), the selective coupling supports preventing deformation of the driving member when the driving member moves. That is, for example, the selective coupling of each driving member (e.g., the first driving member 100a, the second driving member 100b) to one of the two main guide rails MGR1 and MGR2 supports preventing deformation of the driving member when the driving member moves. For example, the embodiments of the present disclosure described herein can prevent deformations such as bending of the driving member, misalignment of the driving member, and imbalance of the driving member.

[0213] For example, in some other display devices, when the main couplers are installed at each of the two ends of the rod of the driving member, if the main coupler at one end (hereinafter referred to as the first main coupler) and the main coupler at the other end (hereinafter referred to as the second main coupler) are not correctly aligned, the driving timings of the first main coupler coupled to the first main guide rail and the second main coupler coupled to the second main guide rail may not be consistent. When this occurs, the driving member including the first main coupler and the second main coupler may be deformed. In contrast, according to an exemplary embodiment of the present disclosure, one driving member is connected to one main guide rail through one coupler in the display device (e.g., each first driving member 100a is coupled to the first main guide rail MGR1 through respective main couplers 120a, and each second driving member 100b is coupled to the second main guide rail MGR2 through respective main couplers 120b), and no alignment problem occurs between the main couplers. As a result, preventing the alignment problem can prevent deformation of the driving members (e.g., the first driving member 100a, the second driving member 100b) and the display panel PNL provided on the driving members.

[0214] In some aspects, in the display device 10 according to the exemplary embodiments described herein, the main coupler 120a of the first driving member 100a and the main coupler 120b of the second driving member 100b (see Figure 9 ) are alternately coupled to different main guide rails MGR1 and MGR2. Even if one driving member is coupled to one main guide rail, this can ensure driving balance of the plurality of driving members 100a and 100b. That is, for example, the main coupler 120a of the first driving member 100a and the main coupler 120b of the second driving member 100b are alternately coupled to the first main guide rail MGR1 and the second main guide rail MGR2.

[0215] In some aspects, since each drive member includes a main coupler (e.g., each first drive member 100a includes main coupler 120a, and each second drive member 100b includes main coupler 120b), the number of main couplers can be reduced, thereby correspondingly reducing the manufacturing cost and weight of each drive member. In some aspects, since the total number of main couplers can be reduced, the friction between each drive member and the main coupler (also referred to herein as the main guiding coupler) can be reduced, and the reduced friction supports easier movement of each drive member with a smaller force. The reduced number of main couplers supports a reduction in the manufacturing cost and weight of the display device 10 described herein.

[0216] In some aspects, for a display device according to an embodiment described herein, the driving force for driving the drive member can be distributed by an auxiliary coupler and an auxiliary guide rail, and the distribution of the driving force supports an increase in the lifespan of the display device 10. In some aspects, since the drive member can be supported by the auxiliary coupler and the auxiliary guide rail, deformation of the drive member can be prevented.

[0217] In some aspects, in the display device 10 according to an exemplary embodiment described herein, one or more drive members can include a plurality of sub-drive members separated from each other, and thus the load on the first main guide rail and the second main guide rail can be reduced, and deformation of the drive member can also be prevented.

[0218] Aspects of the present disclosure support combining any suitable features of the exemplary embodiments described herein. For example, in some embodiments, the display device 10 can include a configuration based on any suitable combination of elements described at least with reference to Figure 9 , Figure 16 , Figure 17 , Figure 19 , Figure 20 and / or Figure 24 and other related descriptions and drawings. In an example, the display device 10 can include the first drive member 100a and the second drive member 100b as described herein. In this example, (not shown), one or more first drive members 100a can be implemented as described at least with reference to Figures 9 to 19 , and one or more other first drive members 100a can be implemented as described at least with reference to Figures 20 to 24 (e.g., including a first sub-drive member 100aS1 and a second sub-drive member 100aS2). Additionally, or alternatively, (not shown), one or more second drive members 100b can be implemented as described at least with reference to Figures 9 to 19 , and one or more other second drive members 100b can be implemented as described at least with reference to Figures 20 to 24implemented as described (e.g., including a first sub-driving member 100bS1 and a second sub-driving member 100bS2).

[0219] Those of ordinary skill in the art to which the present disclosure pertains will be able to understand that the present disclosure can be implemented in other specific forms without changing the technical spirit or essential features of the present disclosure. Accordingly, it will be understood that the example embodiments described herein are illustrative and not restrictive in all respects. It will be understood that the scope of the present disclosure is defined by the claims rather than the detailed description set forth herein, and all modifications and variations derived from the claims and their equivalents fall within the scope of the present disclosure.
