The term "and / or" includes all combinations of one or more components that can be defined by the relevant components.
[0050] Although the terms "first", "second", etc. may be used to describe various components, these components should not be limited by these terms. These terms are only used to distinguish one component from another component. For example, without departing from the scope of the present disclosure, a first component may be referred to as a second component, and similarly, a second component may also be referred to as a first component. Unless otherwise clearly indicated in the context, a singular expression includes a plural expression.
[0051] Also, the terms "under," "beneath," "on," "over," etc. are used to describe the relationship of components shown in the drawings. Conceptually relative terms are described based on the directions shown in the drawings.
[0052] It should be understood that the terms "comprises", "includes", "has", etc. specify the presence of features, numbers, steps, operations, elements, components, or a combination thereof described in the specification, and do not preclude the possibility of the presence or addition of one or more other features, numbers, steps, operations, elements, components, or a combination thereof.
[0053] As used herein, "about" or "approximately" is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, in view of the measurements in question and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system).

[0054] Unless otherwise defined, all terms (including technical terms and scientific terms) used in the specification have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. In addition, terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the meaning in the context of the relevant technology, and should not be interpreted in an overly ideal or overly formal meaning unless clearly defined herein.
[0055] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings.
[0056] Figure 1A is a perspective view of an embodiment of a display device DD according to the present disclosure. Figure 1B is shown in a curled state Figure 1A A perspective view of a display device DD is shown in FIG.
[0057] The display device DD may be a device that is activated according to an electrical signal to display an image IM. In an embodiment, the display device DD may be included in large-sized devices such as televisions and billboards, and small and medium-sized devices such as monitors, mobile phones, tablet computers, navigation devices, and game consoles. Without departing from the concept of the present disclosure, the embodiment of the display device DD is not limited thereto.
[0058] The display device DD in an embodiment may be flexible. The term "flexible" may refer to a property that can be bent, and may include a fully foldable structure as well as a structure that can be bent by a few nanometers. In an embodiment, for example, the flexible display device DD may include a rollable display device that is rolled around a virtual axis. Figure 1AThe display device DD is shown in an unfolded state, and Figure 1B The display device DD is shown in a rolled state.
[0059] refer to Figure 1A , the display device DD in the unfolded state may have a quadrilateral shape in a plan view, for example, a rectangular shape having short sides extending in a first direction DR1 and long sides extending in a second direction DR2 intersecting the first direction DR1. However, the present disclosure is not limited thereto, and the display device DD may have various shapes such as a circle and a polygon.
[0060] The display device DD may generate an image IM in response to an electrical signal and provide the image IM to a user through a display surface DS. The display device DD in the unfolded state may display the image IM in a third direction DR3 on a display surface DS parallel to the first direction DR1 and the second direction DR2. The display surface DS on which the image IM is displayed may correspond to a front surface of the display device DD.
[0061] The images IM provided by the display device DD may include still images as well as dynamic images. Figure 1A A plurality of icons in an embodiment of an image IM is shown.
[0062] The front surface (or upper surface) and the rear surface (or lower surface) of each of the members constituting the display device DD may be opposite to each other in the third direction DR3, and the normal direction of each of the front surface and the rear surface may be substantially parallel to the third direction DR3. The spacing distance between the front surface and the rear surface defined in the third direction DR3 may correspond to the thickness of the member (or unit).
[0063] In the present specification, the wording "in a plan view" may be defined as a state viewed in the third direction DR3. In the present specification, the wording "in a cross section" may be defined as a state viewed from the first direction DR1 or the second direction DR2. The directions indicated by the first direction DR1, the second direction DR2, and the third direction DR3 are relative concepts and may be changed to other directions.
[0064] The display surface DS of the display device DD may include a display area DA and a peripheral area NDA. The display area DA may be an area on which an image IM is displayed, and the peripheral area NDA may be an area on which the image IM is not displayed. The peripheral area NDA may be set as an area having a lower transmittance than that of the display area DA and having a predetermined color.
[0065] The peripheral area NDA may be adjacent to the display area DA. In an embodiment, for example, the peripheral area NDA may surround the display area DA and define an edge of the display device DD. However, the present disclosure is not limited thereto, and the peripheral area NDA may be disposed adjacent to only one side of the display area DA, or may be omitted. In an optional embodiment, the peripheral area NDA may not be disposed on the front surface of the display device DD but on the side surface of the display device DD.
[0066] refer to Figure 1B , the display device DD may be rolled around a virtual rolling axis RX (hereinafter also referred to as a rolling axis RX or a virtual axis RX) extending in one direction. In an embodiment, for example, the display device DD may be rolled around the rolling axis RX extending in the first direction DR1. Figure 1B The rolling axis RX extending in the first direction DR1 parallel to the short side of the display device DD is exemplarily shown, but the present disclosure is not limited thereto, and the display device DD may be rolled about the rolling axis RX parallel to the long side of the display device DD.
[0067] The display device DD can be rolled so that the display surface DS faces the outside. When the display device DD is rolled, the display device DD can be easily carried. Therefore, a large-area display device DD can also be rolled and thus can be accommodated in the accommodating member.
[0068] Figure 2A is a cross-sectional view of an embodiment of a display device DD according to the present disclosure. Figure 2B is a cross-sectional view of an embodiment of a display unit DU according to the present disclosure.
[0069] refer to Figure 2A and Figure 2B The display device DD in the embodiment may include a display unit DU, an upper support member USM disposed below the display unit DU, a lower support member LSM disposed below the upper support member USM, and an intermediate member MM disposed between the upper support member USM and the lower support member LSM. In the embodiment, the display unit DU and the upper support member USM may constitute a display module DM.
[0070] like Figure 2B As shown, the display unit DU may include a display panel DP, an input sensing layer ISP, an upper protection layer UPF, a lower protection layer LPF, an adhesive layer AL, and a window WIN. The display unit DU may be a component activated in response to an electrical signal.
[0071] The display panel DP may be a flexible display panel. The display panel DP in the embodiment of the present disclosure may be a light-emitting display panel, but the present disclosure is not particularly limited thereto. In an embodiment, for example, the display panel DP may be an organic light-emitting display panel or an inorganic light-emitting display panel. The light-emitting layer of the organic light-emitting display panel may include an organic light-emitting material. The light-emitting layer of the inorganic light-emitting display panel may include an inorganic light-emitting material such as a quantum dot or a quantum rod.
[0072] The display panel DP may include a base substrate SUB, a circuit layer CL, a display element layer PXL, and an encapsulation layer TFE. The base substrate SUB, the circuit layer CL, the display element layer PXL, and the encapsulation layer TFE may be sequentially stacked in the third direction DR3.
[0073] The base substrate SUB may include a display area DA and a peripheral area NDA, which may respectively correspond to the display area DA and the peripheral area NDA of the display device DD. The base substrate SUB may provide a base surface on which the circuit layer CL is disposed.
[0074] The base substrate SUB may include a flexible plastic substrate. In an embodiment, for example, the base substrate SUB may include at least one synthetic resin layer. The synthetic resin layer of the base substrate SUB may include at least one of an acryl-based resin, a methacrylate-based resin, a polyisoprene-based resin, a vinyl-based resin, an epoxy-based resin, a urethane-based resin, a cellulose-based resin, a siloxane-based resin, a polyamide-based resin, a perylene-based resin, and a polyimide-based resin.

The circuit layer CL may include a conductive pattern and a semiconductor pattern forming the driving element, the signal line, and the signal pad. After forming the insulating layer, the semiconductor layer, and the conductive layer on the base substrate SUB by coating, deposition, etc., the insulating layer, the semiconductor layer, and the conductive layer are selectively patterned by photolithography, and thus the driving element, the signal line, and the signal pad included in the circuit layer CL may be formed.
[0076] The display element layer PXL may be disposed on the circuit layer CL. The display element layer PXL may include a light emitting element disposed to overlap the display area DA. The light emitting element of the display element layer PXL may be electrically connected to the driving element of the circuit layer CL, and thus may provide a light beam through the display area DA according to a signal of the driving element.
[0077] The encapsulation layer TFE may be disposed on the display element layer PXL to seal the light emitting element. The encapsulation layer TFE may include a plurality of thin films. The thin films of the encapsulation layer TFE may be arranged to improve the optical efficiency of the light emitting element or to protect the light emitting element. In an embodiment, the encapsulation layer TFE may include at least one inorganic film and at least one organic film. The inorganic film of the encapsulation layer TFE may protect the light emitting element from moisture / oxygen. The organic film of the encapsulation layer TFE may protect the light emitting element from impurities such as dust particles.
[0078] The input sensing layer ISP may be disposed on the display panel DP. The input sensing layer ISP may be directly disposed on the display panel DP without a separate adhesive member. That is, after the display panel DP is formed, the input sensing layer ISP may be formed on a base surface provided by the display panel DP through a continuous process. In an embodiment, for example, the input sensing layer ISP may be directly disposed on the encapsulation layer TFE. However, the present disclosure is not limited thereto, and the input sensing layer ISP may be manufactured into a panel shape through a separate manufacturing process different from the process for manufacturing the display panel DP, and may then be attached to the display panel DP through an adhesive member.
[0079] The input detection layer ISP can detect the display device DD (reference Figure 1A ) and obtains coordinate information of the external input. The input detection layer ISP can be driven in various ways such as capacitance, resistance, infrared and pressure, and is not limited to any one of them.
[0080] However, according to the present disclosure, the input detection layer ISP may be omitted.
[0081] The upper protection layer UPF may be disposed on the input sensing layer ISP. The upper protection layer UPF may be coupled to the front surface of the input sensing layer ISP by an adhesive member, but the present disclosure is not limited thereto, and the upper protection layer UPF may be directly formed on the front surface of the input sensing layer ISP.
[0082] The lower protective layer LPF may be disposed under the display panel DP. The lower protective layer LPF may be coupled to the rear surface of the display panel DP by an adhesive member, but the present disclosure is not limited thereto and the lower protective layer LPF may be directly formed on the rear surface of the display panel DP.
[0083] Each of the upper protection layer UPF and the lower protection layer LPF may include at least one of a protection film layer and a shock absorbing layer which protect the display panel DP and the input sensing layer ISP from external impact.
[0084] Each of the upper protective layer UPF and the lower protective layer LPF may include a flexible polymer material such as polyethylene terephthalate and polyimide. The impact absorbing layer may include materials such as sponge, expanded foam, and urethane resin, and may absorb impact applied to the display panel DP and the input sensing layer ISP. The shapes of the upper protective layer UPF and the lower protective layer LPF are not limited to the embodiment as long as the upper protective layer UPF and the lower protective layer LPF may protect the display panel DP and the input sensing layer ISP.
[0085] The adhesive layer AL may be disposed on the upper protective layer UPF. The adhesive layer AL may be disposed between the upper protective layer UPF and the window WIN to couple the upper protective layer UPF and the window WIN. The adhesive layer AL may include a transparent adhesive such as an optically clear adhesive ("OCA") film, an optically clear resin ("OCR"), or a pressure-sensitive adhesive ("PSA") film. However, the type of adhesive included in the adhesive layer AL is not limited thereto.
[0086] The window WIN may be disposed on the upper protection layer UPF. The window WIN may cover the entire outer side of the display panel DP, the input sensing layer ISP, and the upper protection layer UPF, and may protect other components of the display unit DU from external impact and scratches.
[0087] The window WIN may include an optically transparent insulating material. In an embodiment, for example, the window WIN may include glass, sapphire, or a polymer. The window WIN may have a single-layer structure or a multi-layer structure. The window WIN may also include a functional layer such as an anti-fingerprint layer, a phase control layer, and a hard coating layer arranged on an optically transparent substrate.
[0088] The upper support member USM may be disposed under the display unit DU to support the display unit DU, and may be rolled together with the display unit DU. The upper support member USM may be attached to the rear surface of the display unit DU. In an embodiment, for example, the upper support member USM may be attached to the rear surface of the display unit DU by a separate adhesive layer. The upper support member USM may provide a flat surface to the display unit DU to prevent the surface quality of the display unit DU from being deteriorated.
[0089] The lower support member LSM may be disposed below the upper support member USM to support the display unit DU and the upper support member USM. The lower support member LSM may be connected to the upper support member USM and may be rolled together with the display unit DU. However, the present disclosure is not limited thereto, and the lower support member LSM may not be connected to the upper support member USM, may be independently disposed, and thus may not be rolled.
[0090] The middle member MM may be disposed between the upper support member USM and the lower support member LSM to absorb external impact provided to the display module DM disposed on the upper side. Therefore, the display module DM may have predetermined impact resistance and thus the display module DM may be prevented from being damaged by external impact.

The base substrate SUB may provide a base surface on which electrical elements and wirings of the display panel DP are arranged. Figure 3 The base substrate SUB having a quadrilateral shape (eg, a rectangular shape parallel to the first direction DR1 and the second direction DR2) in a plan view is schematically shown, but the present disclosure is not limited thereto, and the base substrate SUB may be configured according to the display device DD (refer to Figure 1A )'s structure is designed into various shapes.
[0093] Each of the pixels PX may include a pixel driving circuit including a light emitting element, a plurality of transistors (e.g., a switching transistor, a driving transistor, etc.) connected to the light emitting element, and at least one capacitor. Each of the pixels PX may emit a light beam in response to an electrical signal applied to the pixel PX.

[0095] Each of the scan driver SDV, the data driver DDV, and the emission driver EDV may be arranged in the peripheral area NDA. However, the present disclosure is not limited thereto, and in an embodiment, at least one of the scan driver SDV, the data driver DDV, and the emission driver EDV may overlap the display area DA. Therefore, the area of the peripheral area NDA may be reduced, and thus the display device DD (refer to Figure 1A )'s border area.
[0096] The data driver DDV may be provided in the form of an integrated circuit chip defined as a driving chip and may be disposed (e.g., mounted) in the peripheral area NDA of the display panel DP.

However, the present disclosure is not limited thereto, and the first power line PL1 may be disposed between the display area DA and the scan driver SDV.
[0100] The connection line CNL may extend in the first direction DR1, may be arranged in the second direction DR2, and may be connected to the first power line PL1 and the pixel PX. The connection line CNL may be arranged in a different layer from the first power line PL1 and electrically connected to the first power line PL1. However, the present disclosure is not limited thereto, and the connection line CNL may be integral in the same layer as the first power line PL1. The first voltage may be applied to the pixel PX through the first power line PL1 and the connection line CNL connected to each other.
[0101] The second power line PL2 may be disposed in the peripheral area NDA. The second power line PL2 may be disposed outside the scan driver SDV and the emission driver EDV. Although not shown separately, the second power line PL2 may extend toward the display area DA and may be connected to the pixel PX. A second voltage having a level lower than the first voltage may be applied to the pixel PX through the second power line PL2. The first voltage and the second voltage may be applied to the electrode of the light emitting element of the pixel PX, and thus, the light emitting element may generate and emit a light beam.
[0102] The first control line CSL1 may be connected to the scan driver SDV. The second control line CSL2 may be connected to the emission driver EDV.
[0103] The pad PD may be arranged adjacent to the lower end of the peripheral area NDA. The pad PD may be disposed closer to the lower end of the display panel DP than the data driver DDV.

[0104] The pad PD may be connected to a corresponding signal line among a plurality of signal lines. The first power line PL1 and the second power line PL2 and the first control line CSL1 and the second control line CSL2 may be connected to the pad PD. The data lines DL1 to DLn may be connected to the corresponding pad PD through the data driver DDV. In an embodiment, for example, the data lines DL1 to DLn may be connected to the data driver DDV, and the data driver DDV may be connected to the pads PD corresponding to the data lines DL1 to DLn, respectively.
[0105] The scan driver SDV may generate a scan signal in response to a scan control signal. The scan signal may be applied to the pixel PX through the scan lines SL1 to SLm.

The light emission signal may be applied to the pixel PX through the emission lines EL1 to ELm.
[0106] The pixel PX may receive a data voltage in response to a scan signal. The pixel PX may display an image IM by emitting a light beam having a brightness corresponding to the data voltage in response to a light emission signal. The light emission time of the pixel PX may be controlled by the light emission signal. The display panel DP may output an image IM through the display area DA through the pixel PX.
[0107] Figure 4A and Figure 4B is a cross-sectional view of an embodiment of a display device DD according to the present disclosure. Figure 4A shows a cross section in the direction in which the long sides of the display device DD extend, and Figure 4B A cross section in the direction in which the short sides of the display device DD extend is shown.
[0108] refer to Figure 4A and Figure 4B The display device DD in the embodiment of the present disclosure may include a display unit DU, an upper support member USM, an intermediate member MM and a lower support member LSM. The description of the display unit DU has been made above with reference to Figure 2B A description has been made and will therefore be omitted.
[0109] The upper support member USM may include an upper support rod USB and a base part BP.
[0110] Each of the upper support rods USB can be parallel to the curling axis RX (see Figure 1B The upper support bars USB may extend in a first direction DR1 of the first direction DR2. The upper support bars USB may be arranged in a second direction DR2 intersecting the direction in which the upper support bars USB extend. The upper support bars USB may be arranged at equal intervals in the second direction DR2. However, the present disclosure is not limited thereto, and the intervals between the upper support bars USB may gradually increase or decrease in the second direction DR2.
[0111] Each of the upper support bars USB may have a rod shape extending in the first direction DR1. Figure 4B As shown, each of the upper support bars USB may have a quadrilateral shape (eg, a rectangular shape) in a cross section viewed in the second direction DR2. However, the shape of each of the upper support bars USB in a cross section is not limited thereto and may be other polygonal shapes or a circular shape.
[0112] The upper support bar USB may have a predetermined stiffness. In an embodiment, for example, the upper support bar USB may include at least one of metal, plastic, carbon fiber, and glass fiber. The upper support bar USB may include aluminum, stainless steel, Invar, carbon fiber reinforced plastic ("CFRP"), glass fiber reinforced plastic ("GFRP"), etc. In addition, in an embodiment, the upper support bar USB may include a metal attached to a magnet.
[0113] The modulus value (or modulus) of each upper support bar USB may be greater than that of the base part BP. The upper support bar USB having a relatively large modulus may support the display unit DU and improve the impact resistance of the upper support member USM.
[0114] The base part BP may be connected to the upper support rod USB. The base part BP may contact the upper support rod USB. The base part BP may cover at least a portion of each of the upper support rods USB. At least a portion of the base part BP may be disposed on the upper support rod USB and cover the upper surface UU of the upper support rod USB.
[0115] In an embodiment, the base part BP may cover all surfaces of the upper support bars USB extending in the first direction DR1. In detail, the base part BP may cover all upper surfaces UU, side surfaces S1-U extending in the first direction DR1, and lower surfaces LU of each of the upper support bars USB. The base part BP may be filled between the upper support bars USB spaced apart from each other in the second direction DR2. Therefore, the upper support bars USB in the embodiment may be disposed within the base part BP.
[0116] In an embodiment, the base part BP may expose the opposite ends of each upper support bar USB. That is, the side surfaces S2-U of each of the upper support bars USB facing each other in the first direction DR1 may be exposed. However, the present disclosure is not limited thereto, and the base part BP may cover the opposite ends of each of the upper support bars USB. In this case, the base part BP may cover the entire surface of each of the upper support bars USB.
[0117] In an embodiment, an edge of the base part BP may be aligned with an edge of the display unit DU. That is, a width of the base part BP in the first direction DR1 and a width of the base part BP in the second direction DR2 may be substantially the same as a width of the display unit DU in the first direction DR1 and a width of the display unit DU in the second direction DR2, respectively.
[0118] The base part BP may include an upper surface UB parallel to the first direction DR1 and the second direction DR2 and a lower surface LB facing the upper surface UB. The interval between the upper surface UB and the lower surface LB of the base part BP may be substantially uniform. Therefore, the thickness of the base part BP may be uniform in the region in which the display unit DU is disposed.
[0119] Since the display unit DU is disposed on the upper surface UB of the base part BP having a flat surface, the portion of the display unit DU overlapping the space between the upper support bars USB is not deformed and remains in a flat state. That is, the surface quality of the display unit DU can be improved by the base part BP.
[0120] The base part BP may include an elastomer having a predetermined elastic force. In an embodiment, for example, the elastomer may include at least one of thermoplastic polyurethane, silicone, thermoplastic rubber, elastic olefin, thermoplastic olefin, polydimethylsiloxane, polyurethane acrylate, polyamide, polyether block amide, synthetic polyisoprene, polybutadiene, chloroprene rubber, butyl rubber, styrene-butadiene, epichlorohydrin rubber, polyacrylic rubber, silicone rubber, fluorosilicone rubber, fluorine-containing elastomer, and ethylene-vinyl acetate.
[0121] The lower support member LSM may be disposed below the upper support member USM. The lower support member LSM may include two support bars (hereinafter also referred to as a first lower support bar LSB1 and a second lower support bar LSB2). The first lower support bar LSB1 and the second lower support bar LSB2 may extend in the second direction DR2 and may be spaced apart from each other in the first direction DR1.
[0122] The first lower supporting bar LSB1 may be adjacent to one side of the display module DM extending in the second direction DR2, and the second lower supporting bar LSB2 may be adjacent to the other side of the display module DM extending in the second direction DR2. In a cross section of the display device DD obtained by cutting one upper supporting bar USB in the first direction DR1, the first lower supporting bar LSB1 may be adjacent to one end of the one upper supporting bar USB, and the second lower supporting bar LSB2 may be adjacent to the other end of the one upper supporting bar USB.
[0123] In an embodiment, the first lower support bar LSB1 may overlap at least a portion of one side of the display module DM extending in the second direction DR2, and the second lower support bar LSB2 may overlap at least a portion of the other side of the display module DM extending in the second direction DR2. The first lower support bar LSB1 may overlap at least some of one ends of the plurality of upper support bars USB, and the second lower support bar LSB2 may overlap at least some of the other ends of the plurality of upper support bars USB. The first lower support bar LSB1 may be substantially aligned with one end of the base part BP through which one end of the upper support bar USB is exposed, and the second lower support bar LSB2 may be substantially aligned with the other end of the base part BP through which the other end of the upper support bar USB is exposed.
[0124] Each of the first lower support bar LSB1 and the second lower support bar LSB2 may have a predetermined rigidity. In an embodiment, for example, each of the first lower support bar LSB1 and the second lower support bar LSB2 may include at least one of metal, plastic, carbon fiber, and glass fiber. Each of the first lower support bar LSB1 and the second lower support bar LSB2 may include aluminum, stainless steel, invar, CFRP, GFRP, etc. However, the material of the first lower support bar LSB1 and the second lower support bar LSB2 is not limited thereto, and may include various materials as long as the first lower support bar LSB1 and the second lower support bar LSB2 can support the display module DM.
[0125] The middle member MM may be disposed between the upper support member USM and the lower support member LSM. The middle member MM may include a first shock absorbing member ASB1 disposed between the upper support member USM and the first lower support bar LSB1 and a second shock absorbing member ASB2 disposed between the upper support member USM and the second lower support bar LSB2.
[0126] In an embodiment, the entirety of the first impact absorbing member ASB1 may overlap with the first lower support bar LSB1, and the entirety of the second impact absorbing member ASB2 may overlap with the second lower support bar LSB2. In an embodiment, for example, the width of the first impact absorbing member ASB1 in the first direction DR1 may be substantially equal to or less than the width of the first lower support bar LSB1 in the first direction DR1, and the width of the second impact absorbing member ASB2 in the first direction DR1 may be substantially equal to or less than the width of the second lower support bar LSB2 in the first direction DR1. However, the present disclosure is not limited thereto, and the width of the first impact absorbing member ASB1 in the first direction DR1 may be greater than the width of the first lower support bar LSB1 in the first direction DR1, and the width of the second impact absorbing member ASB2 in the first direction DR1 may be greater than the width of the second lower support bar LSB2 in the first direction DR1.
[0127] The first impact absorbing member ASB1 and the second impact absorbing member ASB2 may have a modulus value (or modulus) smaller than the modulus value (or modulus) of the first lower support bar LSB1 and the second lower support bar LSB2, respectively. In addition, the first impact absorbing member ASB1 and the second impact absorbing member ASB2 may have a modulus value smaller than the modulus value of the upper support member USM (particularly, the base part BP). In an embodiment, each of the first impact absorbing member ASB1 and the second impact absorbing member ASB2 may include a porous material such as a sponge and a foam. In an embodiment, for example, the sponge may include polyether, polyvinyl alcohol, and polyester, and the foam may include polyurethane. In an optional embodiment, each of the first impact absorbing member ASB1 and the second impact absorbing member ASB2 may include rubber.
[0128] In an embodiment, the thickness of each of the first impact absorbing member ASB1 and the second impact absorbing member ASB2 may be 1 millimeter (mm) or less. When the thickness of each of the first impact absorbing member ASB1 and the second impact absorbing member ASB2 exceeds 1 mm, deformation such as bending may easily occur in the display module DM due to a predetermined external pressure. However, the thickness of each of the first impact absorbing member ASB1 and the second impact absorbing member ASB2 is not limited thereto, and the appropriate thickness may vary according to the material and / or thickness of the components within the upper support member USM.
[0129] Figure 5 is a cross-sectional view of an embodiment of a pen-drop display device DD according to the present disclosure. Figure 5 A cross section in the direction in which the short sides of the display device DD extend is shown. Figure 51 shows a cross section at a time point when an external impact is applied to the upper portion of the display device DD, and exemplarily shows that the external impact is applied by a pen drop. The same or similar reference numerals are used for Figures 1A to 4B The same or similar components described in the drawings will be described herein, and repeated description thereof will be omitted.
[0130] refer to Figure 5 , when an external impact is applied to a local area of the display device DD by the pen falling, the first lower support bar LSB1 and the second lower support bar LSB2 support the display module DM, and thus the upper support bar USB to which the external impact is applied may bend in the direction in which the pen PN falls. In this case, a bend may be formed in the entire upper support bar USB to which the external impact is applied.
[0131] The base part BP and the display unit DU may also bend together with the upper support rod USB in the direction in which the pen PN is lowered near the area to which the external impact is applied, and thus, a bend may be formed in the entire base part BP and the entire display unit DU. Therefore, the impact applied to a local area by the external impact may be transmitted to a more extended area, thereby improving the impact resistance of the display device DD.
[0132] When an external impact is applied to the vicinity of the center of the display module DM, when the upper supporting bar USB is sufficiently bent, the impact applied to the vicinity of the center can be transmitted to a more extended area and thus be sufficiently absorbed, and thus the impact force applied to the display device DD can be reduced.
[0133] When an external impact is applied near the edge of the display module DM adjacent to the first lower support bar LSB1 or the second lower support bar LSB2, even when the upper support bar USB is supported by the first lower support bar LSB1 or the second lower support bar LSB2, the external impact can be absorbed by the first impact absorbing member ASB1 or the second impact absorbing member ASB2, and thus the impact force applied to the display device DD can be reduced. In more detail, when the first impact absorbing member ASB1 or the second impact absorbing member ASB2 is pressed near the area where the external impact is applied, the thickness of the first impact absorbing member ASB1 or the second impact absorbing member ASB2 can be reduced, and thus the upper support bar USB can be bent in the direction in which the pen PN drops.
[0134] Therefore, the lower support member LSM and the middle member MM according to the present disclosure can absorb the external impact regardless of the point to which the external impact is applied, and thus the impact resistance in the entire area of the display module DM can be improved. The damage to the display unit DU caused by the external impact can be prevented, and thus the damage to the display surface DS (reference Figure 1A ) appears on the display device DD. Therefore, a display device DD with improved reliability can be provided.
[0135] Fig. 6A is a cross-sectional view of a comparative example of a display device in which a pen drop test is performed. Figure 6B is a cross-sectional view of an embodiment of a display device in which a pen drop test is performed according to the present disclosure. Fig. 7A is a graph showing the relationship between the pen drop point and the maximum pen drop height in a comparative example of a display device. Figure 7B is a graph showing the relationship between the pen drop point and the maximum height of the pen drop in an embodiment of the display device according to the present disclosure. FIG. 6A to FIG. 7B , the impact resistance against pen drop in a comparative example of a display device DD′ and an embodiment of a display device DD according to the present disclosure will be described.
[0136] like Fig. 6A As shown, a comparative example of a display device DD' in which a pen drop test is performed includes a display unit DU', an upper support member USM', and a lower support member LSM'. The upper support member USM' includes a base BP' and an upper support rod USB' arranged inside the base BP', and the lower support member LSM' includes a first lower support rod LSB1' and a second lower support rod LSB2'. In the comparative example, each of the first lower support rod LSB1' and the second lower support rod LSB2' contacts the upper support member USM'.
[0137] like Figure 6B As shown, the display device DD in which the pen drop test is performed in the embodiment of the present disclosure includes a display unit DU, an upper support member USM, an intermediate member MM, and a lower support member LSM. The upper support member USM includes a base BP and an upper support rod USB arranged inside the base BP, the lower support member LSM includes a first lower support rod LSB1 and a second lower support rod LSB2, and the intermediate member MM includes a first impact absorbing member ASB1 disposed between the upper support member USM and the first lower support rod LSB1 and a second impact absorbing member ASB2 disposed between the upper support member USM and the second lower support rod LSB2. In the test, each of the first impact absorbing member ASB1 and the second impact absorbing member ASB2 is a sponge including a thickness of about 1 mm.
[0138] like Fig. 6A and Figure 6B As shown in FIG. 1 , the pen drop test is performed in a manner of dropping the pen PN onto the display devices DD′ and DD to be tested. In detail, for each preset pen drop point, the pen drop test is performed while changing the pen drop heights H1 and H2, and the pen drop heights H1 and H2 on the display panel DP (reference Figure 3) is the maximum height of the pen drop without a dark spot appearing on the display module DM' and DM. In this case, the pen drop point refers to the distance away from the center of the display modules DM' and DM, and the distances d1 and d2 between the center C' and C of the display modules DM' and DM and the points P' and P separated from the center C' and C of the display modules DM' and DM in the first direction DR1 are written as positive values, and the distances between the center C' and C of the display modules DM' and DM and the points separated from the center C' and C of the display modules DM' and DM in the direction opposite to the first direction DR1 are written as negative values. In the test, the width of each of the display modules DM' and DM in the first direction DR1 is set to 200mm, and the pen drop point is set to -80mm, -60mm, -40mm, -20mm, 0mm, 20mm, 40mm, 60mm and 80mm.
[0139] Furthermore, in the test, the test was performed while the pen drop heights H1 and H2 were increased by 1 cm at a time starting from 1 centimeter (cm) and the pen drop height at which a dark spot first appeared at each preset pen drop point was measured. Fig. 7A and Figure 7B The maximum height of the pen drop shown in the figure refers to the height of the pen drop on the display panel DP (reference Figure 3 ) is the maximum value of the pen drop height at which no dark spot appears, and this corresponds to the value obtained by subtracting 1 cm from the pen drop height at which a dark spot appears.
[0140] like Fig. 7A As shown, according to the comparative example, when the pen drop is performed at a point P' from -20 mm to 20 mm, it can be confirmed that the display panel DP (reference Figure 3 ) can be 7 cm to 8 cm. According to the comparative example, when the pen drop is performed at a point P' greater than 20 mm and less than -20 mm, it can be confirmed that when the pen drop point is far from the center C' of the display module DM', the display panel DP (reference Figure 3 ) is reduced. When the point P' at which the pen is dropped is set near the edge of the display module DM' adjacent to the first lower support bar LSB1' or the second lower support bar LSB2', it can be confirmed that the display panel DP (reference Figure 3 ) is reduced to a maximum height of 1 cm to 2 cm without any dark spots appearing on the surface.
[0141] like Figure 7B As shown, according to the present disclosure, it can be confirmed that at the point P where the pen is dropped, on the display panel DP (reference Figure 3) may be 7 cm to 8 cm. Therefore, even when the pen drop point becomes farther from the center C of the display module DM and becomes adjacent to the first lower support bar LSB1 or the second lower support bar LSB2, it can be confirmed that the pen drop point is located on the display panel DP (reference Figure 3 ) is similar to the maximum height of the pen drop when the pen drop point is set near the center of the display module DM.
[0142] Therefore, in the embodiment, when an external impact is applied near the edge of the display module DM adjacent to the first lower supporting bar LSB1 or the second lower supporting bar LSB2, it can be confirmed that the external impact can be absorbed by the first impact absorbing member ASB1 or the second impact absorbing member ASB2, and thus, the display module DM can be prevented from being damaged. Therefore, it can be confirmed that the impact resistance is improved in the entire area of the display module DM.

The one surface of the shell CS may be spaced apart from another surface of the shell CS adjacent to the holder HD in the second direction DR2. The roller ROL may have a cylindrical shape extending in the first direction DR1, and when viewed in the first direction DR1, the roller ROL may have a circular shape. The extending direction of the roller ROL may correspond to the curling axis RX (see Figure 1B ) in an extending direction. The roller ROL may rotate clockwise or counterclockwise. Although not shown separately, the electronic device ED may further include a driving portion for rotating the roller ROL.
[0156] One end of the display module DM may be connected to the roller ROL. The display module DM may be wound around the roller ROL and accommodated in the housing CS. The display module DM may be rolled by the roller ROL. When the roller ROL rotates in one direction, the display module DM may be rolled while surrounding the roller ROL.

When the holder HD moves away from the case CS in the second direction DR2, the roller ROL may rotate in a direction opposite to the one direction, and at least a portion of the display module DM may be deployed outside the case CS.
[0158] Fig. 10A The electronic device ED is shown in a state where the display device DD is accommodated in the case CS and the display module DM is rolled. Fig. 10A exemplarily shows that a portion of the display device DD in the rolled state is exposed from the opening C-OP of the casing CS to provide a display surface DS (refer to FIG. Figure 1A ) of the electronic device ED, but the present disclosure is not limited thereto. In the rolled state, the display device DD can be completely inserted into the housing CS.
[0159] Fig. 10B and Fig.11 The electronic device ED is shown in a state where the display module DM is unfolded. In the unfolded state, the display device DD exposed from the housing CS can provide an extended display surface DS (refer to Figure 1A That is, the display surface DS of the display device DD (refer to Figure 1A ) can be adjusted according to the movement of the retaining member HD.
[0160] The display device DD may include a display module DM, an intermediate member MM (refer to Figure 4A and Figure 4B ) and the lower support member LSM (reference Figure 4A and Figure 4B The display module DM may include a display unit DU (refer to Figure 4A and Figure 4B ) and upper support member USM (reference Figure 4A and Figure 4B The above description can also be applied to the display module DM, the intermediate member MM (refer to Figure 4A and Figure 4B ) and the lower support member LSM (reference Figure 4A and Figure 4B ).

In detail, when the holder HD moves, the lower support bar LSB may be unfolded or folded, and in this case, the shock absorbing member ASB may also be unfolded or folded together with the lower support bar LSB. In this case, the shock absorbing member ASB may not be connected to the display module DM, and thus may not be curled together with the display module DM.
[0162] In an embodiment, the lower support bar LSB may include a support portion SPP and at least one hinge portion HGP connecting the support portion SPP. Fig.11 It is schematically shown that the lower support rod LSB includes four support portions SPP and three hinge portions HGP.

[0176] refer to Fig.14A and Fig. 14B , the electronic device EDa in the embodiment of the present disclosure may include a display device DDa and a housing CSa in which the display device DDa is accommodated. At least a portion of the display device DDa may be exposed to the outside through an opening C-OPa defined in an upper portion of the housing CSa.
[0177] The housing CSa may include a first housing CS1 and a second housing CS2. The first housing CS1 and the second housing CS2 may be coupled to each other to accommodate the display device DDa. The first housing CS1 may be coupled to the second housing CS2 to move in a direction parallel to the second direction DR2. The first housing CS1 may be coupled to the second housing CS2 to move closer to or further away from the second housing CS2.
[0178] refer to Fig.14A and Fig. 14B , display surface DS (reference Figure 1A ) of the housing CSa exposed by the opening C-OPa may be adjusted as the first housing CS1 moves. When the first housing CS1 moves, the opening area of the opening C-OPa may increase in the second direction DR2.
[0179] Fig.14A The electronic device EDa is shown in a state (hereinafter also referred to as a basic mode) where the first casing CS1 is closest to the second casing CS2 in the second direction DR2 when the display device DDa is operating. Fig. 14B The electronic device EDa is shown in a state where the first shell CS1 is spaced the largest from the second shell CS2 in the second direction DR2 (hereinafter also referred to as the extended mode) when the display device DDa is in operation. The user can adjust the display surface DS (refer to FIG. 1 ) of the display device DDa by selecting either the basic mode or the extended mode of the display device DDa. Figure 1A )The area exposed from the shell CSa is adjusted differently.
[0180] The display device DDa may be a flexible display device. The display device DDa may be accommodated in the housing CSa when folded. When the first housing CS1 moves, the display surface DS (refer to Figure 1A ) is exposed to the outside. One end of the display device DDa can move in the second direction DR2 together with the first housing CS1, and the portion of the display device DDa accommodated in the second housing CS2 can be exposed to the outside. Therefore, the display surface DS (reference numeral 20) of the display device DDa exposed through the opening C-OPa Figure 1A ) can be expanded.
[0181] refer to Fig.15 , the display device DDa in the embodiment may include a display unit DUa and an upper supporting member USMa.
[0182] In an embodiment, the display unit DUa may include a first area AA1 and a second area AA2 extending from the first area AA1 in a second direction DR2. When the basic mode is switched to the extended mode, the first area AA1 of the display unit DUa may be moved along the roll ROLa (reference Fig.16A and Fig. 16B ), which will be described below. That is, a portion of the first area AA1 of the display unit DUa may be disposed on the curved surface of the roller ROLa and bent to have a predetermined curvature.
[0183] In an embodiment, the upper support member USMa may include a cover member CVM, a first support layer SPL1, a second support layer SPL2, and an upper support rod USBa.

The cover member CVM may support the first area AA1 of the display unit DUa that is bent at a predetermined curvature, thereby alleviating stress caused by the bending. In addition, the cover member CVM may prevent impurities from entering the display unit DUa through the opening P-OP defined in the first support layer SPL1, which will be described below.
[0186] Even during operation in the basic mode and the extended mode, the unbent second area AA2 of the display unit DUa does not want to release stress due to bending, and no opening is defined in the second supporting layer SPL2 disposed under the second area AA2 of the display unit DUa, and thus the cover member CVM is not disposed. Therefore, the stacked structure corresponding to the second area AA2 of the display device DDa can be simplified.
[0187] The first supporting layer SPL1 may be disposed under the cover member CVM. The first supporting layer SPL1 may overlap the first area AA1. The first supporting layer SPL1 may not overlap the second area AA2.
[0188] The first support layer SPL1 may include a material having a predetermined rigidity.

[0189] A plurality of openings P-OP passing through the first supporting layer SPL1 may be defined in the first supporting layer SPL1. The first supporting layer SPL1 may be relatively easily bent through the openings P-OP. That is, the first supporting layer SPL1 may have rigidity while being easily bent with a predetermined curvature through the openings P-OP.
[0190] Each of the openings P-OP may extend in the first direction DR1. That is, the width of the openings P-OP in the first direction DR1 may be greater than the width of the openings P-OP in the second direction DR2. The openings P-OP may be arranged in a grid shape. Therefore, a grid pattern may be formed on the first supporting layer SPL1 through the openings P-OP.
[0191] The opening P-OP may include a first opening OP1 and a second opening OP2, and the first opening OP1 and the second opening OP2 are arranged to deviate from each other in a direction parallel to the second direction DR2. The first opening OP1 and the second opening OP2 may be arranged in a row in the first direction DR1, respectively. However, this is shown exemplarily, and the plurality of openings P-OP in the embodiment of the present disclosure may all be arranged side by side in the second direction DR2, and the present disclosure is not limited to the embodiment.
[0192] Fig.15 It is shown that the openings P-OP are arranged in a plurality of groups arranged in the second direction DR2, and one group includes a first opening OP1 arranged in one row and a second opening OP2 arranged on the opposite side of the first opening OP1 and arranged in two rows. However, this is shown exemplarily, and the arrangement form and intervals of the openings P-OP may be variously designed according to the design of the display device DDa, and are not limited to any one design.
[0193] The second supporting layer SPL2 may be disposed below the display unit DUa. The second supporting layer SPL2 may overlap the second area AA2. The second supporting layer SPL2 may not overlap the first area AA1. The second supporting layer SPL2 may be spaced apart from the first supporting layer SPL1. The second supporting layer SPL2 may have a plate shape parallel to the first direction DR1 and the second direction DR2. The second supporting layer SPL2 may protect the rear surface of the display unit DUa corresponding to the second area AA2.
[0194] The second supporting layer SPL2 may include a material having a predetermined rigidity. In an embodiment, the second supporting layer SPL2 may include, for example, stainless steel, aluminum, or any alloy of aluminum. However, the material of the second supporting layer SPL2 is not limited to the above embodiment. The second supporting layer SPL2 may include a material that is the same as or different from that of the first supporting layer SPL1. The second supporting layer SPL2 may support the second area AA2 of the display unit DUa so that the second area AA2 of the display unit DUa maintains a flat state in the basic mode and the extended mode. In addition, the second supporting layer SPL2 may improve the impact resistance for the second area AA2 of the display unit DUa.
[0195] The second supporting layer SPL2 may include a material different from that of the covering member CVM. The second supporting layer SPL2 may have a modulus greater than that of the covering member CVM. The covering member CVM and the second supporting layer SPL2 are not limited to the embodiments as long as the covering member CVM can support the first area AA1 to relieve stress caused by bending and the second supporting layer SPL2 can uniformly support the second area AA2.
[0196] The upper support bar USBa may be arranged on the rear surface of the first support layer SPL1. The upper support bar USBa may extend in the first direction DR1. The upper support bar USBa may be spaced apart from each other in the second direction DR2. The upper support bar USBa may be provided as a plurality of divided bodies and allow the first area AA1 to be easily moved along the roller ROLa (reference Fig.16A and Fig. 16B )'s curved surface is curved, which will be described below.
[0197] The upper support bars USBa may not overlap the openings P-OP of the first support layer SPL1. Therefore, the upper support bars USBa may not deteriorate the bending characteristics of the first support layer SPL1. However, the embodiment is not necessarily limited thereto, and some of the upper support bars USBa may overlap the openings P-OP.
[0198] The upper support bar USBa may include a metal having a predetermined rigidity. In an embodiment, the upper support bar USBa may include a metal such as aluminum, stainless steel, or Invar, or may include carbon fiber. However, the upper support bar USBa is provided as a plurality of split bodies, and the material of the upper support bar USBa is not limited to the above embodiment, as long as the upper support bar USBa can support the first area AA1.

Fig. 16B The electronic device EDa in the embodiment corresponds to Fig. 14BThat is, Fig.16A corresponds to a cross section of the electronic device EDa in basic mode, and Fig. 16B Corresponds to the cross section of the electronic device EDa in the extended mode.
[0200] refer to Fig.16A and Fig. 16B , the electronic device EDa in the embodiment may include a housing CSa, a display device DDa accommodated in the housing CSa, and a roller ROLa.
[0201] In an embodiment, the display device DDa may include a display module DMa, a first middle member MM1a, a first lower support member LSM1a, a second middle member MM2a, and a second lower support member LSM2a.

Fig.15 The description made can be equally applied to the description of the display unit DUa and the upper supporting member USMa.
[0202] In the basic mode, the display surface DS corresponding to the second area AA2 (refer to Figure 1A ) may be exposed to the outside. A portion of the first area AA1 may be bent so that one end thereof spaced apart from the second area AA2 overlaps the second area AA2 in the third direction DR3. In the basic mode, the display surface DS (reference Figure 1A ) may be exposed to the outside together. However, the present disclosure is not limited thereto, and in a basic mode, the display surface DS (reference Figure 1A ) may not be exposed to the outside.
[0203] The roller ROLa may be accommodated in the second housing CS2. The roller ROLa may rotate about a rotation axis parallel to one direction. Fig.16A and Fig. 16B A roller ROLa rotatable about a rotation axis parallel to the first direction DR1 is shown. The roller ROLa may be coupled to the second housing CS2 and rotate about the rotation axis according to a sliding operation of the first housing CS1 moving away from or approaching the second housing CS2.
[0204] Fig.16A The first housing CS1 can move away from the second housing CS2 in the second direction DR2, and thus the current mode can be Fig. 16BWhen the electronic device EDa is switched from the basic mode to the extended mode, one end of the display module DMa that is spaced apart from the first area AA1 and corresponds to the second area AA2 is fixedly connected to the first shell CS1, and can therefore move together when the first shell CS1 moves. In this case, one end of the display module DMa that is spaced apart from the second area AA2 and corresponds to the first area AA1 can move in a direction opposite to the end of the second area AA2 that is connected to the first shell CS1.
[0205] A portion of the first area AA1 of the display unit DUa, a cover member CVM supporting the portion of the first area AA1 of the display unit DUa, a first support layer SPL1, and some upper support rods USBa may be arranged on the curved surface of the roller ROLa and bent to have a predetermined curvature. When the basic mode is switched to the extended mode, when the display unit DUa moves, the first area AA1 of the display unit DUa, the cover member CVM, the first support layer SPL1, and the upper support rods USBa may move along the curved surface of the roller ROLa. In an embodiment, in the basic mode, the display surface DS (reference Figure 1A ) may be exposed to the outside, and when the basic mode is switched to the extended mode, the area of the first area AA1 exposed to the outside through the opening C-OPa may increase.
[0206] As mentioned above Fig.15 As described, the components supporting the first area AA1 that bends along the curved surface of the roller ROLa in the basic mode and the extended mode and the components supporting the second area AA2 that remains flat in the basic mode and the extended mode have different desired mechanical properties, and therefore the components supporting the first area AA1 and the components supporting the second area AA2 can be different from each other.
[0207] The first lower support member LSM1a may be connected to the second case CS2. The first middle member MM1a may be disposed on the first lower support member LSM1a.

That is, the first lower supporting member LSM1a may support the portion of the display module DMa corresponding to the first area AA1 that provides the display surface DS in the extended mode (refer to FIG. Figure 1A ) part.
[0209] The second lower support member LSM2a may be connected to the first case CS1. The second intermediate member MM2a may be disposed on the second lower support member LSM2a.

That is, the second lower supporting member LSM2a may support the display module DMa corresponding to the second area AA2. Since the display module DMa corresponding to the second area AA2 provides a display surface DS (reference Figure 1A ), so the second lower supporting member LSM2a may be disposed to support the display module DMa corresponding to the second area AA2 in both the basic mode and the extended mode.
[0211] Each of the first lower support member LSM1a and the second lower support member LSM2a may have a predetermined rigidity. In an embodiment, each of the first lower support member LSM1a and the second lower support member LSM2a may include at least one of metal, plastic, carbon fiber, and glass fiber. For example, each of the first lower support member LSM1a and the second lower support member LSM2a may include aluminum, stainless steel, Invar, CFRP, GFRP, etc. However, the material of the first lower support member LSM1a and the second lower support member LSM2a is not limited thereto, and may include various materials as long as the first lower support member LSM1a and the second lower support member LSM2a can support the display module DM.
[0212] The first intermediate member MM1a and the second intermediate member MM2a may have a modulus value lower than the modulus value of the first lower support member LSM1a and the second lower support member LSM2a.

Damage to the display unit DUa due to external impact can be prevented, and thus the display surface DS (reference Figure 1A ) appears on the display device DDa. Therefore, a display device DDa with improved reliability can be provided.
