[0065] 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, various 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 the present disclosure will be thorough and complete, and will fully convey the scope of the example aspects of the present invention to those skilled in the art.

[0066] Terms such as first and second, etc., can be used to describe various components, but these components should not be limited by these terms. These terms used in this article can distinguish a component from other components and are not limited by these terms. For example, without departing from the scope of this disclosure, a first component can be referred to as a second component, and similarly, a second component can also be referred to as a first component. Unless otherwise stated, a term in the singular form can include a plural form.

[0067] The terms used herein are only used for the purpose of describing specific embodiments, and are not intended to be limited. Unless the context clearly indicates otherwise, as used herein, "one", "one (kind / person)", "the (said)" and "at least one (kind / person)" do not represent the limitation of quantity, and are intended to include both the singular and the plural. Unless the context clearly indicates otherwise, for example, "element (an element)" and "at least one element" have the same meaning. "At least one (kind / person)" will not be interpreted as limiting "one" or "one (kind / person)". "Or" means "and / or". As used herein, the term "and / or" includes any combination and all combinations of one or more related listed items. It will also be understood that when used in this specification, the term "comprises and / or comprising" or "includes and / or including" indicates the presence of stated features, regions, wholes, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, regions, wholes, steps, operations, elements, components and / or their groups.

[0068] As used herein, the terms "about" or "approximately" include the stated value and include a range of appropriate deviations for the particular value as determined by one of ordinary skill in the art, taking into account the measurement in question and the errors associated with the measurement of a particular quantity. For example, the term "about" may mean within one or more standard deviations, or within ±30%, ±20%, ±10%, or ±5% of the stated value.

[0069] As used herein, "about" or "approximately" includes the stated value and means within the range of acceptable deviations for the particular value determined by one of ordinary skill in the art, taking into account the measurement in question and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations, or within ±30%, ±20%, ±10%, or ±5% of the stated value.

[0070] As used herein, the term "substantially" means approximately or substantially equal (e.g., within a threshold percentage of equality). As used herein, the term "substantially simultaneously" means approximately or substantially simultaneous (e.g., within a threshold percentage of equality). As used herein, the term "substantially identical" means approximately or substantially identical (e.g., within a threshold differential).

[0071] For ease of description, spatially relative terms such as "under," "below," "below," "above," and "on" may be used herein to describe the relationship of one element or feature to another element (or elements) or feature (or features) as shown in the accompanying drawings. It will be understood that, in addition to the orientations depicted in the accompanying drawings, spatially relative terms are intended to cover different orientations of the device in use or operation. For example, if the device is flipped in the accompanying drawings, an element described as "under" or "below" other elements or features will then be oriented "above" the other elements or features. Therefore, the term "under" can cover both above and below. The device can be oriented in other ways (e.g., rotated 90 degrees or at other orientations), and the spatially relative terms used herein are interpreted accordingly.

[0072] Embodiments are described herein with reference to schematically illustrated cross-sectional illustrations as idealized embodiments. Therefore, variations in the shapes of the illustrations due to, for example, manufacturing techniques and / or tolerances are expected. Therefore, the embodiments described herein should not be interpreted as being limited to the specific shapes of the zones shown herein, but rather include deviations in shapes due to, for example, manufacturing. For example, a zone shown or described as flat may typically have rough and / or nonlinear features. In addition, the sharp corners shown may be rounded. Therefore, the zones shown in the drawings are schematic in nature, and their shapes are not intended to illustrate the precise shapes of the zones, and are not intended to limit the scope of the claims.

[0073] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the present disclosure belongs. It will also be understood that, unless explicitly defined as such herein, terms (such as those defined in general dictionaries) should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formalized sense.

[0074] 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 specific embodiments, and include various changes, equivalents or alternatives of the corresponding embodiments. With regard to the description of the accompanying drawings, similar reference numerals may be used to refer to similar or related elements. It will be understood that, unless the relevant context clearly indicates otherwise, the singular form of the 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 a corresponding phrase.

[0075] It will be understood that if an element (e.g., a first element) is referred to as being “coupled with,” “coupled to,” “connected to,” or “connected to…” another element (e.g., a second element) with or without the term “operably” or “communicatively,” this means that the element can be coupled to the other element directly (e.g., wired), wirelessly, or through a third element.

[0076] Hereinafter, example embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0077] Figure 1 is a plan view of a display device 10 according to an embodiment of the present disclosure. Figure 2 It is used to show Figure 1 A view showing an expanded state of the display panel PNL. Figure 3 is a graph showing the direction along which the Figure 1 1 is a cross-sectional view of the display device 10 taken along line II′.

[0078] The display device 10 according to the 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 not limited to) a single-direction 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-direction 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-slidable display device 10, but aspects of the present disclosure are not limited thereto.

[0079] like Figures 1 to 3 As shown in , 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 rail MGR1, a second main rail MGR2, a first auxiliary rail AGR1, and a second auxiliary rail AGR2.

[0080] The display panel PNL can display an image therein. The embodiments of the present disclosure support the use of any suitable type of display panel as the display panel PNL, such as an organic light-emitting display panel including an organic light-emitting layer, a micro light-emitting diode display panel using a micro light-emitting diode (LED), a quantum dot light-emitting display panel using a quantum dot light-emitting diode including a quantum dot light-emitting layer, and an inorganic light-emitting display panel using an inorganic light-emitting element including an inorganic semiconductor.

[0081] The display panel PNL may be a flexible panel. The display panel PNL may have flexibility so that the display panel PNL may be partially curled, bent, or curved along the first main rail MGR1 and the second main rail MGR2. The display panel PNL may slide in a first direction DR1 and a direction opposite to the first direction DR1 (referred to herein as a first opposite direction).

[0082] The outer surface of the display panel PNL (eg, Figure 1 The surface shown in (a) may be a surface on which an image is displayed. In some embodiments, the inner surface of the display panel PNL may face the first support plate 201. The inner surface of the display panel PNL may 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, may be disposed on opposite sides of each other, and the outer surface and the inner surface of the second support plate 202 may be disposed on opposite sides of each other.

[0083] The area of ​​the display area of ​​the display panel PNL may 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 closed state), the display panel PNL may have a first display area DA1 of a first area. In an example in which the display device 10 is slid open (hereinafter referred to as the second state or open state (unfolded state)), in addition to the first display area DA1, the display area may also include an unfolded second display area DA2. In some aspects, the area of ​​the display area in the second state may 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 area in the second state may increase. In other words, the area of ​​the display area of ​​the display panel PNL may vary based on the state of the display device 10. In the open state, the area of ​​the display area of ​​the display panel PNL may vary based on the degree of the open state (for example, the amount by which the display device 10 is slid open).

[0084] The display panel PNL may be disposed on an outer surface of the first support plate 201. The display panel PNL may be attached to the outer surface of the first support plate 201. For example, the inner surface of the display panel PNL may be attached to the outer surface of the first support plate 201. The display panel PNL may be fixed to the first support plate 201. The first support plate 201 may be formed of a flexible material that may be bent.

[0085] The second support plate 202 may be disposed on an inner surface of the first support plate 201. The second support plate 202 may be attached to the inner surface of the first support plate 201. For example, the outer surface of the second support plate 202 may be attached to the inner surface of the first support plate 201. The second support plate 202 may be fixed to the first support plate 201. The second support plate 202 may be formed of a flexible material that may be bent.

[0086] A plurality of driving members 100a and 100b may be disposed on the inner surface of the second support plate 202. For example, a plurality of driving members 100a and 100b may be disposed on the second support plate 202 so that the plurality of driving members 100a and 100b are equally spaced from each other in the first direction DR1. The plurality of driving members 100a and 100b may be arranged parallel to each other. The plurality of driving members 100a and 100b may be attached to the inner surface of the first support plate 201. The plurality of driving members 100a and 100b may be fixed to the first support plate 201.

[0087] The first main rail MGR1 may be disposed at one side of the display panel PNL.

[0088] The second main guide rail MGR2 may be disposed on an 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 an 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 be facing away from each other in the second direction DR2. Alternatively, the first main guide rail MGR1 and the second main guide rail MGR2 may face each other in the second direction DR2.

[0089] like Figure 3 As shown in , the first auxiliary rail AGR1 and the second auxiliary rail AGR2 can be arranged between the first main rail MGR1 and the second main rail MGR2. The first auxiliary rail AGR1 can be arranged opposite to the second auxiliary rail AGR2 (for example, arranged on the opposite side of the second auxiliary rail AGR2). The first auxiliary rail AGR1 can be arranged adjacent to the first main rail MGR1, and the second auxiliary rail AGR2 can be arranged adjacent to the second main rail MGR2.

[0090] like Figure 3 As shown in FIG. 1 , a plurality of driving members 100 a and 100 b may be disposed between the first main rail MGR1 and the second main rail MGR2 .

[0091] The driving members 100a and 100b may be movably coupled to one of the first and second main rails MGR1 and MGR2. In some aspects, the driving members 100a and 100b may be movably coupled to the first and second auxiliary rails AGR1 and AGR2.

[0092] Figure 4 yes Figure 1 1 is a perspective view of a display device 10 . Figure 5 yes Figure 4 sectional view of a first main rail MGR1 in a display device 10. Figure 6 yes Figure 5 First magnified view of area AA. Figure 7 yes Figure 6 Side view of area AA shown in . Figure 8 yes Figure 5 A second magnified view of area AA.

[0093] Fig. 9 is based on Figure 5 1 is a plan view of a plurality of driving members 100a and 100b and a second support plate 202 of an embodiment of the present invention.

[0094] exist Figure 6 In the first enlarged view shown in FIG. Figure 5 The first auxiliary guide rail AGR1 is included among the plurality of elements in the area AA so as not to obstruct the description herein. Figure 8 In the second enlarged view shown in FIG. Figure 5 The first main rail MGR1 and the coupler are shown among the multiple elements of area AA so as not to obstruct the description herein.

[0095] like Figure 4 As shown in FIG. 1 , the first main rail MGR1 may be disposed at one side of the display panel PNL. The first main rail MGR1 may have an elliptical shape. Figure 4 Although not shown in the drawings, the second main rail MGR2 may have the same configuration as the first main rail MGR1. For example, the second main rail MGR2 may have an elliptical shape that is the same as or substantially the same as that of the first main rail MGR1.

[0096] like Figure 3 , Figure 5 , Figure 6 , Figure 7 and Fig. 9 As shown in , a plurality of driving members 100a and 100b may be coupled to one of the first main rail MGR1 and the second main rail MGR2. In other words, a plurality of driving members 100a and 100b may be movably coupled to one of the first main rail MGR1 and the second main rail MGR2. For example, a plurality of driving members 100a and 100b may be movable in the first main rail MGR1 and the second main rail MGR2.

[0097] like Figure 3 and Fig. 9 As shown in FIG. 2 , each of the driving members 100 a and 100 b may have a rod shape extending in the second direction DR2 .

[0098] Each of the driving members 100a and 100b may be selectively coupled to one of the first main rail MGR1 and the second main rail MGR2 without being coupled to the other of the first main rail MGR1 and the second main rail MGR2. For example, each of the driving members 100a and 100b may be selectively coupled to one of the first main rail MGR1 and the second main rail MGR2 (e.g., only one of the first main rail MGR1 and the second main rail MGR2). In the example, the first driving member 100a may be coupled to the first main rail MGR1, and the second driving member 100b may be coupled to the second main rail MGR2, wherein the driving members disposed in the odd columns (or even columns) are defined as the first driving members 100a relative to the first direction DR1, and the driving members disposed in the even columns (or odd columns) are defined as the second driving members 100b relative to the first direction DR1. The first driving members 100a and the second driving members 100b may be arranged alternately. In other words, the plurality of first driving members 100 a and the plurality of second driving members 100 b may be alternately arranged.

[0099] In some aspects, such as Figure 3 , Figure 5 , Figure 6 , Figure 7 and Fig. 9 As shown in , a plurality of drive members 100a and 100b may be movably connected to the first auxiliary rail AGR1 and the second auxiliary rail AGR2. For example, each of the plurality of first drive members 100a may be movably coupled to the first auxiliary rail AGR1 and the second auxiliary rail AGR2, and each of the plurality of second drive members 100b may be movably coupled to the first auxiliary rail AGR1 and the second auxiliary rail AGR2.

[0100] like Figure 3 , Figure 5 , Figure 8 and Fig. 9 As shown in , the first auxiliary guide rail AGR1 may include a first guide rail R11 and a second guide rail R12 facing each other and spaced apart from each other. The guide hole GHa may 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 may define the guide hole GHa.

[0101] like Figure 3 , Figure 5 , Figure 8 and Fig. 9As shown in , the second auxiliary guide rail AGR2 may include a first guide rail R21 and a second guide rail R22 facing each other and 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 construction of the second auxiliary guide rail AGR2 may be the same or substantially the same as the construction of the first auxiliary guide rail AGR1 described herein.

[0102] Each of the driving members 100a and 100b may be coupled to the first and second auxiliary rails AGR1 and AGR2. For example, each of the driving members 100a and 100b may be coupled to the guide hole GHa of the first and second auxiliary rails AGR1 and AGR2.

[0103] As described herein, each of the drive members 100a and 100b is coupled to the first main rail MGR1 or the second main rail MGR2, and may also be coupled to the first auxiliary rail AGR1 and the second auxiliary rail AGR2. For example, the first drive member 100a may be coupled to the first main rail MGR1, the first auxiliary rail AGR1 and the second auxiliary rail AGR2. In an example, the second drive member 100b may be coupled to the second main rail MGR2, the first auxiliary rail AGR1 and the second auxiliary rail AGR2.

[0104] like Fig. 9 As shown in FIG. 1 , the first drive member 100 a may include a rod 110 a , a main coupler 120 a , a first auxiliary coupler 131 a , and a second auxiliary coupler 132 a .

[0105] The rod 110 a of the first driving member 100 a may have a rod shape extending in the second direction DR2 .

[0106] 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 be coupled to the first main rail MGR1.

[0107] The first auxiliary coupler 131a of the first drive member 100a can be arranged on the rod 110a so that the first auxiliary coupler 131a is adjacent to one end of the first drive member 100a (or the main coupler 120a).

[0178] The first protrusion 121aS2 of the second sub driving member 100aS2 may protrude from the second rod 110aS2. For example, the first protrusion 121aS2 may protrude in the second direction DR2.

[0179] The second protrusion 122aS2 of the second sub-driving member 100aS2 may face the first protrusion 121aS2. The second protrusion 122aS2 may protrude in the second direction DR2. The second protrusion 122aS2 may be parallel to the first protrusion 121aS2. Fig. 20) may be disposed between the first protrusion 121aS2 and the second protrusion 122aS2 of the second sub-drive member 100aS2. In other words, the second sub-drive member 100aS2 may be coupled to the second main rail MGR2 via the first protrusion 121aS2 and the second protrusion 122aS2 of the second main coupler 120aS2. In the example in which the second sub-drive member 100aS2 is coupled to the second main rail MGR2, the first protrusion 121aS2 of the second sub-drive member 100aS2 may face the outer surface (or outer peripheral surface) of the second main rail MGR2, and the second protrusion 122aS2 of the second sub-drive member 100aS2 may face the inner surface (or inner peripheral surface) of the second main rail MGR2.

The connecting piece 123aS2 may protrude from the first protrusion 121aS2 in the third direction DR3. The connecting piece 123aS2 may be disposed between the first protrusion 121aS2 and the second protrusion 122aS2. One side of the connecting piece 123aS2 may be connected to the first protrusion 121aS2, and the opposite side of the connecting piece 123aS2 may be connected to the second protrusion 122aS2. The first protrusion 121aS2, the second protrusion 122aS2, and the connecting piece 123aS2 may be formed as one body.

[0181] The second main coupler 120aS2 including the first protrusion 121aS2, the second protrusion 122aS2, and the connection piece 123aS2 may have, for example, a C-shape or a U-shape.

[0182] For example, opposite ends of the first sub driving member 100aS1 and the second sub driving member 100aS2 may face each other in the second direction DR2.

[0183] It should be noted that Fig. 20 The second driving member 100b can be connected with Fig. 20 The first driving member 100a has the same configuration. For example, the second driving member 100b may include a first sub-driving member 100bS1 and a second sub-driving member 100bS2 separated from each other. The first sub-driving member 100bS1 of the second driving member 100b may be coupled to the first main rail MGR1, and the second sub-driving member 100bS2 of the second driving member 100b may be coupled to the second main rail MGR2.

[0184] In some aspects, according to embodiments, Fig. 20 The second driving member 100b can be connected with Fig. 9 , Fig.16 and Fig.17 The second driving member 100b has the same configuration or substantially the same configuration.

[0185] Fig.24 is a plan view of a plurality of driving members 100a and 100b and a second support plate 202 according to an embodiment.

[0186] Fig.24 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. Fig.24 The display device 10 and Fig. 20 Display device 10 (see Figure 1 ) is different in that Fig.24 The display device 10 further includes a first auxiliary coupler 131aS1 and a second auxiliary coupler 132aS2. The following description will focus on Fig.24 The display device 10 and Fig. 20 The differences between the display devices 10 are shown in FIG.

[0187] like Fig.24 As shown in , the first sub-driving member 100aS1 of the first driving member 100a may also include a first auxiliary coupler 131aS1, and the second sub-driving member 100aS2 of the first driving member 100a may also 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.

[0188] Fig.24 The first auxiliary coupler 131aS1 and the second auxiliary coupler 132aS2 can be respectively connected to the auxiliary coupler described in this article. Fig.19 The first auxiliary coupler 131a and the second auxiliary coupler 132a are identical.

[0189] It should be noted that Fig.24 The second driving member 100b can be connected with Fig.24The first drive member 100a has the same structure. For example, the first sub-drive member 100bS1 of the second drive member 100b may also include a first auxiliary coupler 131bS1, and the second sub-drive member 100bS2 of the second drive member 100b may also include a second auxiliary coupler 132bS2. That is, for example, each of the plurality of first sub-drive members 100bS1 may include a first auxiliary coupler 131bS1, and each of the plurality of second sub-drive members 100bS2 may include a second auxiliary coupler 132bS2.

[0190] In some aspects, according to embodiments, Fig.24 The second driving member 100b can be connected with Fig. 9 , Fig.16 , Fig.17 and Fig. 20 The second driving member 100b has the same configuration.

[0191] Fig.25 It is used to show Figure 5 A view showing an expanded state of the display panel PNL.

[0192] like Fig.25 As shown in , when the display device 10 slides open or is slid open (for example, partially opened or fully opened) (that is, the display device 10 is in the second state), in addition to the first display area DA1, the display area may also include an expanded second display area DA2.

[0193] In some embodiments, Fig.25 As shown in FIG. 1 , the first driving member 100a moves along the first main guide rail MGR1, the first auxiliary guide rail AGR1 and the second auxiliary guide rail AGR2 (see FIG. 1 ). Figure 3 ) moves counterclockwise. In some aspects, although not shown in the drawings, the second drive member 100b (see Figure 3 ) can be along the second main rail MGR2 (see Figure 3 ), the first auxiliary guide rail AGR1 and the second auxiliary guide rail AGR2 move counterclockwise.

[0194] In other words, when the first and second driving members 100a and 100b move counterclockwise along the first main rail MGR1 (or the second main rail MGR2), the first and second auxiliary rails AGR1 and AGR2, the display area of ​​the display panel PNL may be expanded.

[0195] In the display device according to the embodiments described herein, since one driving member 100a or 100b is selectively coupled to one of the two main rails MGR1 and MGR2 (e.g., only one of the two main rails MGR1 and MGR2), the selective coupling supports the prevention of 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 rails MGR1 and MGR2 supports the prevention of deformation of the driving member when the driving member moves. For example, the embodiments of the present disclosure described herein can prevent deformation such as, for example, bending of the driving member, misalignment of the driving member, and imbalance of the driving member.

[0196] For example, in some other display devices, when the main coupler is 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 properly aligned, the driving timing of the first main coupler coupled to the first main rail may be inconsistent with the driving timing of the second main coupler coupled to the second main rail. When this happens, 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 rail through one coupler in the display device (for example, each first driving member 100a is coupled to the first main rail MGR1 through each main coupler 120a, and each second driving member 100b is coupled to the second main rail MGR2 through each main coupler 120b), and no alignment problem occurs between the main couplers. As a result, preventing the alignment problem may prevent deformation of the driving member (eg, the first driving member 100 a , the second driving member 100 b ) and the display panel PNL disposed on the driving member.

[0197] In some aspects, in the display device 10 according to the example 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 Fig. 9 ) are alternately coupled to different main rails MGR1 and MGR2, which can ensure the driving balance of the plurality of driving members 100a and 100b even if one driving member is coupled to one main rail. 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 rail MGR1 and the second main rail MGR2.

[0198] In some aspects, since each drive member includes a main coupler (e.g., each first drive member 100a includes a main coupler 120a, and each second drive member 100b includes a 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 a main guide coupler) can be reduced, and the reduced friction supports easier movement of each drive member with less force. The reduced number of main couplers supports a reduction in the manufacturing cost and weight of the display device 10 described herein.

[0199] In some aspects, according to the display device of the embodiments described herein, the driving force for driving the driving member can be distributed by the auxiliary coupler and the auxiliary guide rail, and the distribution of the driving force supports increasing the life of the display device 10. In some aspects, since the driving member can be supported by the auxiliary coupler and the auxiliary guide rail, deformation of the driving member can be prevented.

[0200] In some aspects, in a display device 10 according to the example embodiments described herein, one or more driving members may include a plurality of sub-driving members separated from each other, and thereby reduce the load on the first main rail and the second main rail, and also prevent deformation of the driving member.

[0201] Aspects of the present disclosure support combining any suitable features of the example embodiments described herein. For example, in some embodiments, the display device 10 may include a display device 10 based on at least a reference Fig. 9 , Fig.16 , Fig.17 , Fig.19 , Fig. 20 and / or Fig.24 In an example, the display device 10 may include a first drive member 100a and a second drive member 100b as described herein. In this example, (not shown), one or more first drive members 100a may be as described in at least reference to Figures 9 to 19 The description is implemented, and one or more other first drive members 100a can be as described with reference to at least Figure 20 to Figure 24 As described above, the invention can be implemented (for example, including a first sub-driving member 100aS1 and a second sub-driving member 100aS2). In addition, or alternatively, (not shown), one or more second driving members 100b can be as described with reference to at least Figures 9 to 19 The description is implemented, and one or more other second drive members 100b can be as at least referenced Figure 20 to Figure 24The method is described as follows (eg, including a first sub-driving member 100bS1 and a second sub-driving member 100bS2).

[0202] It will be understood by those skilled in the art that the present disclosure may be implemented in other specific forms without changing the technical spirit or essential features of the present disclosure. Therefore, it will be understood that the example embodiments described herein are illustrative rather than restrictive in all aspects. It will be understood that the scope of the present disclosure is defined by the claims rather than the detailed description described herein, and all modifications and changes derived from the claims and their equivalents fall within the scope of the present disclosure.
