Description

Technical Field

[0001] The present disclosure relates to a display device and a movable device including the same, and more particularly, to a display device having a structure that effectively copes with external impact and a movable device including the same. Background Art

[0002] The content described in this background section merely provides background information about the present disclosure and does not constitute prior art.

[0003] As we enter the mature information age, display devices that visually express electrical information signals have rapidly developed. In response to this, various display devices with excellent performance, thinness, lightness, and low power consumption have been developed.

[0004] Display devices include liquid crystal display devices (LCD), quantum dot (QD) display devices, field emission display devices (FED), electrowetting display devices (EWD), and organic light emitting display devices (OLED), etc.

[0005] Display devices are miniaturized so that they can be carried by users. Display devices have been developed to be mounted on mobile devices such as vehicles. Thus, users can use the display devices on the vehicle more conveniently. Summary of the Invention

[0006] When the display device is mounted on a movable device (eg, a vehicle, a bicycle, an airplane, etc.), a shock received from the outside due to the movement may be transferred to the display device.

[0007] Due to external impact, the display device may be deformed or, in severe cases, damaged by the external impact. When the damage is severe, fragments of the display device can injure a user on a vehicle (eg, a mobile device).

[0008] Even if such a display device is not damaged when it receives an external impact, malfunction, failure, etc. of the display device may occur due to the external impact.

[0009] Particularly, in the case of a display device having a slim structure or a display device having a curved flexible structure, the influence of the external impact may be greater.

[0010] Therefore, in the case where a display device is mounted on a movable device such as a vehicle, it is necessary to manufacture the display device having a structure capable of stably enduring external impact.

[0011] Therefore, an object of the present disclosure is to provide a display device having a structure capable of effectively coping with external impact.

[0012] Furthermore, an object of the present disclosure is to provide a display device having a structure capable of suppressing damage by allowing a fastening portion to move when subjected to an external impact.

[0013] The purpose of the present disclosure is not limited to the above-mentioned purpose. Other unmentioned purposes and advantages of the present disclosure can be understood based on the following description and can be more clearly understood based on the embodiments of the present disclosure. In addition, it will be readily understood that the purposes and advantages of the present disclosure can be achieved using the means and combinations thereof shown in the claims.

The second bracket may include a protrusion protruding from the second bracket, and the protrusion of the second bracket may have a fastening hole defined therein.

[0018] The fastening hole defined in the protrusion may be sized such that a diameter of the protrusion in a first direction is larger than a diameter of the protrusion in a second direction perpendicular to the first direction.

[0049] The display device 10 according to the embodiment can be installed on a movable device (eg, a vehicle) to provide convenience to the user. Hereinafter, the display device 10 installed on the dashboard of the vehicle will be described as an example.

[0050] The display device according to the embodiment may include, for example, a liquid crystal display device (LCD), a quantum dot (QD) display device, a field emission display device (FED), an electrowetting display device (EWD), and an organic light emitting display device (OLED), etc. However, the present disclosure is not limited thereto.

[0051] Figure 1 1 is a front view of a display device 10 according to an embodiment. The display device 10 may include a display panel 100 on which an image or video is displayed. The display panel 100 may generally have a rectangular or square shape, but is not limited thereto and may have an acute or obtuse angle or a curved shape.

[0052] Figure 2 It shows Figure 1 Figure 1-1' of part I-I'.

[0053] Reference Figure 1 and Figure 2 , the substrate 111 can support various components of the display panel 100. The substrate 111 can be made of a transparent insulating material, for example, an insulating material such as glass, plastic, etc. When the substrate 111 is made of plastic, the substrate 111 can be a plastic film or a plastic substrate. For example, the substrate 111 can be in the form of a film containing one or more of a polyimide-based polymer, a polyether-based polymer, a silicone-based polymer, an acrylic-based polymer, a polyolefin-based polymer, and copolymers thereof. Among these materials, polyimide can be used as a plastic substrate because it can be applied to high-temperature processes and can be coated.

[0054] A buffer layer may be located on the substrate 111. The buffer layer may protect the thin film transistor (TFT) from impurities such as alkali ions leaking from the bottom of the substrate 111. The buffer layer may be made of silicon oxide (SiOx), silicon nitride (SiNx), or may be composed of a plurality of layers thereof, but the present disclosure may not be limited thereto.

[0055] The thin film transistor 130 (i.e., 130(T)) may be provided on the buffer layer. A gate electrode 132, a gate insulating layer 112, a semiconductor layer 134, an interlayer insulating layer 114, and source and drain electrodes 136 and 138 may be sequentially provided to constitute the thin film transistor 130. At least one thin film transistor 130 may be provided in a plurality of sub-pixels arranged in the active region.

[0056] although Figure 2The thin film transistor 130 shown in FIG. 1 applies a bottom gate scheme, but the present disclosure is not limited thereto, and a top gate scheme in which the order of the semiconductor layer 134 and the gate electrode 132 is changed may be applied.

[0057] The semiconductor layer 134 may be provided on a specific portion of the substrate 111 or the buffer layer. The semiconductor layer 134 may be made of polycrystalline silicon (p-Si). In this case, a portion of the semiconductor layer 134, which is a region that will become an electrode layer, may be doped with impurities. In addition, the semiconductor layer 134 may be made of amorphous silicon (a-Si) and may be made of various organic semiconductor materials such as pentacene. As another example, the semiconductor layer 134 may be made of an oxide. The gate insulating layer 112 may be made of an insulating inorganic material such as silicon oxide (SiOx) or silicon nitride (SiNx), or may be made of an insulating organic material. The gate 132 may be made of various conductive materials, for example, magnesium (Mg), aluminum (Al), nickel (Ni), chromium (Cr), molybdenum (Mo), tungsten (W), gold (Au), or alloys thereof, but the present disclosure may not be limited thereto.

[0058] The first interlayer insulating layer 114 may be made of an insulating material such as silicon oxide (SiOx) or silicon nitride (SiNx), or may be made of an insulating organic material. By selectively removing the first interlayer insulating layer 114, contact holes through which the source and drain regions are exposed may be defined.

[0059] The source electrode 136 and the drain electrode 138 may be formed in the form of a single layer or multiple layers of electrode material on the first interlayer insulating layer 114 .

[0060] The inorganic passivation layer 116 and the planarization layer 118 may be located on the thin film transistor while covering the source electrode 136 and the drain electrode 138. The inorganic passivation layer 116 and the planarization layer 118 protect the thin film transistor and planarize the top of the thin film transistor. The inorganic passivation layer 116 may be formed as an inorganic insulating film, such as a silicon nitride film (SiNx) and a silicon oxide film (SiOx), and the planarization layer 118 may be formed as an organic insulating film, such as BCB (benzocyclobutene) or acrylic acid. Each of the inorganic passivation layer 116 and the planarization layer 118 may be composed of a single layer or may be composed of a double layer or multiple layers, and one of the inorganic passivation layer 116 and the planarization layer 118 may be omitted.

[0061] The light-emitting element connected to the thin film transistor (TFT) 130 may have a form in which a first electrode 122, an organic light-emitting layer 124, and a second electrode 126 are sequentially provided. For example, the light-emitting element may be composed of the following: the first electrode 122, the first electrode 122 being connected to the drain electrode 138 through a contact hole 148 defined in the planarization layer 118 and the inorganic passivation layer 116; the organic light-emitting layer 124 located on the first electrode 122; and the second electrode 126 located on the organic light-emitting layer 124.

[0062] When the display panel 100 adopts a top emission scheme in which light is emitted from the top of the second electrode 126 (for example, toward the cover member 180), the first electrode 122 may include an opaque conductive material with high reflectivity. The opaque conductive material with high reflectivity may be, for example, silver (Ag), aluminum (Al), gold (Au), molybdenum (Mo), tungsten (W), chromium (Cr), or an alloy thereof, but the present disclosure may not be limited thereto.

[0063] The bank 128 opens the light-emitting region and is formed in the remaining region except the light-emitting region. Therefore, the bank 128 has a bank hole corresponding to the light-emitting region to expose the first electrode 122. The bank 128 can be made of an inorganic insulating material such as a silicon nitride film (SiNx) or a silicon oxide film (SiOx) or an organic insulating material such as BCB, an acrylic resin, or an imide resin.

[0064] The organic light-emitting layer 124 is disposed on the first electrode 122 exposed by the bank 128. The organic light-emitting layer 124 may include a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, an electron injection layer, and the like. In addition, the organic light-emitting layer 124 may have a single light-emitting layer structure that emits one light beam in a single stack, or may have a multi-stack structure that includes a plurality of stacks and includes a single light-emitting layer of the same color in each stack. In this case, in order to display various colors, adjacent sub-pixels may be arranged to emit light beams of different colors. For example, sub-pixels having red, green, and blue light-emitting layers may be arranged side by side in sequence, or may be arranged at intervals from each other and have a triangle or pentile structure in which two sub-pixels of a specific color are parallel to each other and another sub-pixel is arranged diagonally.

[0065] As another example, a white sub-pixel arrangement can be added. In another arrangement structure of the organic light-emitting layer 124, white can be represented by stacking multiple stacks including light-emitting layers that emit light of different colors. When the stack structure is used to represent white, a separate color filter can be added to each sub-pixel.

[0066] The second electrode 126 is provided on the organic light emitting layer 124. When the display panel 100 adopts a top emission scheme, the second electrode 126 may be made of a transparent conductive material such as indium tin oxide (ITO), indium zinc oxide (IZO), or the like, or may be made of a semi-transmissive metal or a metal alloy such as MgAg, so as to emit light generated by the organic light emitting layer 124 from the top of the second electrode 126.

[0067] A capping layer may be provided on the second electrode 126. The capping layer may protect the light emitting element and may be formed of a material having a good refractive index, thereby helping to extract light from the second electrode 126.

[0068] The encapsulation layer 140 may be provided on the light-emitting element. The encapsulation layer 140 blocks oxygen and moisture from penetrating from the outside to prevent oxidation of the light-emitting material and the electrode material. When the light-emitting element is exposed to moisture or oxygen, a pixel shrinkage phenomenon in which the light-emitting area is reduced may occur, or dark spots may appear in the light-emitting area. The encapsulation layer 140 may be formed by alternating first and second inorganic layers 142 and 146 made of glass, metal, aluminum oxide (AlOx) or silicon (Si) based materials, and an organic layer 144 serving as a buffer layer to reduce stress between layers (e.g., the first and second inorganic layers 142 and 146) caused by bending of the display panel 100 and enhance flattening performance. That is, the first and second inorganic layers 142 and 146 may be made of glass, metal, aluminum oxide (AlOx) or silicon (Si) based materials. The composition of the organic layer 144 may be an organic insulating material, such as acrylic resin, epoxy resin, polyimide, polyethylene or silicon oxycarbon (SiOC). The first inorganic layer 142 and the second inorganic layer 146 are used to block the penetration of moisture or oxygen, and the organic layer 144 is used to planarize the surface of the first inorganic layer 142. When the encapsulation layer 140 is composed of multiple thin film layers, the flow path of moisture or oxygen may become longer and more complex than the flow path of a single layer, which may make it difficult for moisture / oxygen to penetrate the light-emitting element.

[0069] A passivation layer may be further formed between the light emitting element and the encapsulation layer 140 to protect the encapsulation layer 140 so that the side surface of the encapsulation layer 140 is not peeled off during the manufacturing process of the encapsulation layer 140 or the uniformity thereof is not affected.

[0070] Reference Figure 2 , a polarizing layer 154 may be disposed on the encapsulation layer 140 . The polarizing layer 154 may minimize the influence of light generated from an external light source and entering the display panel 100 on the semiconductor layer 134 or the light emitting layer 124 .

[0071] Reference Figure 2, the touch sensor layer 155 may be provided on the polarization layer 154. The touch sensor layer 155 may have a structure in which the first touch electrodes 155a and the second touch electrodes 155c are arranged to cross each other (e.g., contact each other), and a voltage signal is applied to one side (e.g., the first side) and the voltage signal is sensed on the other side (e.g., the second side). The first touch electrodes 155a and the second touch electrodes 155c may be patterned into polygons or circles (e.g., any shape) on the touch insulation layer 155b and are spaced apart from each other (e.g., the first touch electrode 155a may be spaced apart from the second touch electrode 155c).

[0072] The cover member 180 may be disposed on the touch sensor layer 155. An adhesive layer may be further disposed between the touch sensor layer 155 and the cover member 180 to bond the touch sensor layer 155 and the cover member 180 to each other.

[0073] Figure 3 is a perspective view illustrating a display device 10 according to an embodiment. The display device 10 may include a back cover 200 coupled to a rear surface (eg, a rear surface) of the display panel 100 to support the display panel 100 .

[0074] The back cover 200 may be coupled to a portion of the rear of the display panel 100 and support the display panel 100, and the back cover 200 itself may be coupled to the dashboard of the vehicle (or a fixture of a movable device). In order to couple the back cover 200 with the dashboard, the back cover 200 may have a protrusion 210.

[0075] A coupling device 1000, such as a screw, may be coupled to the protrusion 210 and the coupling device 1000 may be connected to the dashboard, so that the display device 10 can be stably coupled to the dashboard. In order to stably couple the display device 10 to the dashboard, a plurality of protrusions 210 may be provided on the rear cover 200, and a plurality of coupling devices 1000 may be attached / coupled to the plurality of protrusions 210 of the rear cover 200 to attach / couple the rear cover 200 to the dashboard.

[0076] For example, a plurality of protrusions 210 may be provided and disposed to be spaced apart from each other on the back cover 200. The protrusions 210 may protrude from the back cover 200 and may define fastening holes 211 therein to which the coupling device 1000 is fastened.

[0077] The back cover 200 may include a first bracket 220 and a second bracket 230. The first bracket 220 may protrude from the back cover 200. The second bracket 230 may protrude from the back cover 200 and be disposed at a position spaced apart from the first bracket 220.

[0078] The first bracket 220 and the second bracket 230 may have the necessary means for electrically connecting the display device 10 to an external power source, a vehicle controller (e.g., a hardware embedded processor), and other external devices. In order to stably connect the display device 10 to a fixed device (e.g., an instrument panel), a protrusion 210 may also be formed on the first bracket 220 and the second bracket 230.

[0079] The first bracket 220 may include a protrusion 210 protruding from the first bracket 220 and having a fastening hole 211 defined therein. The second bracket 230 may include a protrusion 210 protruding from the second bracket 230 and having a fastening hole 211 defined therein.

[0080] Similar to the protrusion 210 provided on the rear cover 200, the protrusion 210 provided on the first bracket 220 and the second bracket 230 may include a plurality of protrusions spaced apart from each other. In order to more stably couple the display device 10 to the dashboard, the first bracket 220 and the second bracket 230 further include a plurality of protrusions 210 for coupling.

[0081] Hereinafter, the protrusion 210 provided on the rear cover 200, the first bracket 220, and the second bracket 230 will be described in common as a description of the protrusion 210. Therefore, for example, the protrusion 210 provided on the rear cover 200 may be applied to the protrusion 210 provided on the first bracket 220 and the second bracket 230 unless otherwise specified.

[0082] Figure 4 It's from the other direction, isn't it? Figure 3 . The display device 10 mounted on a vehicle may receive an external impact while the vehicle is running. Specifically, when the vehicle suddenly stops due to an obstacle or a traffic accident, an external impact (e.g., a force caused by an external impact or a force caused by sudden acceleration or deceleration of the vehicle) may be applied to the display device 10.

[0083] like Figure 4 As shown by the arrow in , such external impact or force may be applied primarily in the front-to-rear direction of the display device 10 mounted on the dashboard of the vehicle (e.g., an axis passing through the front and rear of the display panel 100), that is, in the first direction. Therefore, the following description will be based on the first direction, which is the direction in which external impact that may damage the display device 10 is primarily applied.

[0084] Figure 52 is a partially enlarged view showing the protrusion 210 and the fastening hole 211 according to an embodiment. In the fastening hole 211 defined in the protrusion 210, the diameter D1 (e.g., length) in the first direction may be greater than the diameter D2 (e.g., length) in the second direction perpendicular to the first direction. Since the diameter D1 in the first direction is larger, the coupling device 1000 such as a screw fastened to the fastening hole 211 can move in the first direction. In addition, the fastening hole 211 may include various shapes having a curved surface and a plurality of straight surfaces, such as Figure 5 , as shown in (e.g., a variable shape). The diameter D1 may represent the maximum diameter of the fastening hole 211 in the first direction, and the fastening hole 211 may have the diameter D1 in the first direction from the first end of the fastening hole toward the second end of the fastening hole. The diameter D2 may represent the maximum diameter of the fastening hole 211 in the second direction, and the fastening hole 211 may have a diameter D2 that increases from the first end toward the second end. The second end of the fastening hole may have a semicircular shape, as shown in FIG. Figure 5 As shown in .

[0085] The diameter D2 in the second direction may increase or decrease in the first direction. For example, the fastening hole 211 may be defined so that the diameter D2 in the second direction decreases in the rearward direction of the display panel 100, that is, decreases in the +x-axis direction from the point where the diameter D2 in the second direction is the largest.

[0086] Reference Figure 5 , for example, the diameter D2 in the second direction may increase in the −x-axis direction, ie, decrease in the +x-axis direction.

[0087] Due to this structure, the fastening hole 211 may be composed of a first region 2111 having a relatively small diameter and varying in diameter in a first direction, and a second region 2112 having a relatively larger diameter than the first region 2111 .

[0088] The first direction may be parallel to the front-rear direction of the display panel 100. To allow a user to conveniently view the display panel 100 in a vehicle, the display panel 100 may be disposed such that its front-rear direction is parallel to the front-rear direction of the vehicle.

[0089] As described above, during the operation of the vehicle, external impacts mainly occur in the front and rear directions of the vehicle. Therefore, the external impacts applied to the display device 10 (for example, impact force, acceleration force, braking force, etc.) can also be mainly applied in the front and rear directions of the display panel 100, that is, in the first direction.

[0090] Therefore, the first direction is parallel to the front-rear direction of the display panel 100 , so that the display panel 100 may move in the first direction due to the fastening holes 211 elongatedly defined in the first direction, thereby moving in response to a direction in which the external impact is mainly applied.

[0091] Figure 6 2 is a partially enlarged view illustrating a state in which the coupling device 1000 according to the embodiment is fastened to the fastening hole 211 defined in the protrusion 210 . Figure 7 It shows Figure 6 FIG. 1000 is a diagram showing the moving state of the coupling device 1000. Figure 6 and Figure 7 , arrows indicate directions in which external impact is applied to the display device 10 .

[0092] exist Figure 6 In the embodiment, the coupling device 1000 is fastened to the protrusion 210 and the dashboard (e.g., the coupling device 1000 can fix the protrusion 210 to the dashboard or other fixing device), and thus, the display device 10 is coupled to the dashboard. In this regard, the coupling device 1000 is located in the first area 2111 of the fastening hole 211. Figure 6 In the state of , an external impact may be applied to the display device 10 in the +x-axis direction as shown by an arrow.

[0093] When the display apparatus 10 is applied with an external impact, the coupling device 1000 fixedly coupled to the instrument panel maintains its position, but the display apparatus 10 subjected to the external impact (eg, external force) may move in the direction of the arrow.

[0094] Therefore, if Figure 7 As shown in , the protrusion 210 of the display device 10 is movable in the direction of the arrow shown, and therefore, the coupling device 1000 is movable in the direction opposite to the arrow, that is, in the −x-axis direction when viewed relative to the protrusion 210 .

[0095] The first region 2111 of the fastening hole 211 may be defined elongated in the first direction, and in particular, the diameter may increase in the -x-axis direction. Due to this structure, the coupling device 1000 may move in the -x-axis direction, which is the direction in which the diameter increases, in response to an external impact applied in the direction of the arrow.

[0096] Therefore, when an external impact is applied to the display device 10 in the direction of the arrow, the display device 10 can move in the +x-axis direction relative to the coupling device 1000. In this way, the display device 10 can move in the first direction in response to the external impact (e.g., external force), and the range of movement of the display device 10 in the first direction can be determined by the diameter D1 in the first direction. That is, the range of movement can be equivalent to (e.g., equal to) the diameter D1 of the fastening hole 211.

[0097] In one example, when the connecting device 1000 is fastened to the protrusion 210, it is preferred to appropriately adjust the fastening strength of the connecting device 1000 so that the protrusion 210 can move relative to the connecting device 1000 only when the intensity of the external impact is equal to or greater than a certain intensity (for example, the force applied to the display device 10 is greater than a predetermined force).

[0098] In one embodiment, the protrusion 210 provided on the display apparatus 10 moves in response to an external impact (eg, an external force), so that the display apparatus 10 having the protrusion 210 can effectively absorb the external impact to suppress damage.

[0099] Figure 8 is a partially enlarged view showing the protrusion 210 and the fastening hole 211 according to the embodiment. Figure 8 The contents of the fastening hole 211 shown in FIG. 2 are repeated in the description of the fastening hole 211 described above.

[0100] Figure 8 The fastening hole 211 of the embodiment shown in FIG may include a first portion 2113 and a second portion 2114. The diameter D2 of the first portion 2113 may decrease in the second direction from a point where the diameter D2 in the second direction is the largest in the rear direction of the display panel 100. The first portion 2113 may have a straight line shape and the second portion may have a straight line shape.

[0101] In the second portion 2114, the diameter D2 in the second direction may be constantly maintained from a point where the diameter D2 in the second direction is largest in the rear direction of the display panel 100. In this regard, the first portion 2113 and the second portion 2114 may be alternately arranged along the first direction.

[0102] Figure 8 The fastening hole 211 of the embodiment shown in FIG can be defined such that, when the first portion 2113 and the second portion 2114 are alternately arranged, the diameter in the second direction changes in a step-like manner while having a stepped shape as a whole. That is, since the first portion 2113 and the second portion 2114 are alternately arranged, the fastening hole 211 can have a stepped shape (e.g., a stepped shape).

[0103] Figure 9 is a partially enlarged view illustrating the protrusion 210 and the fastening hole 211 according to the embodiment. Figure 9 The fastening hole 211 of the embodiment shown in FIG. 2 may include a first unit 2115 and a second unit 2116 separated from each other by the deformable portion 212 of the protrusion 210 .

[0104] The first unit 2115 may be formed in a substantially circular shape, and the coupling device 1000 may be coupled to the first unit 2115. Therefore, the first unit 2115 may have the same diameter D1 in the first direction and the same diameter D2 in the second direction. For example, the first unit 2115 may have a circular shape with a fixed diameter.

[0105] The second unit 2116 may be separated from the first unit 2115 and defined at a position spaced apart from the first unit 2115. In this regard, in the second unit 2116, a diameter D1 in the first direction may be smaller than a diameter D2 in the second direction.

[0106] The first unit 2115 and the second unit 2116 may be spaced apart from each other in the first direction. Therefore, when an external impact is applied to the display apparatus 10, the coupling device 1000 may move in the first direction.

[0107] The protrusion 210 may include a deformable portion 212 that separates the first unit 2115 and the second unit 2116 of the fastening hole 211. The deformable portion 212 may be provided between the first unit 2115 and the second unit 2116 to separate the first unit 2115 and the second unit 2116 from each other, and may be deformed (e.g., plastically deformed or elastically deformed) or damaged when an external force is applied to the display device 10. For example, the deformable portion 212 may be configured to absorb part or all of the external force applied to the display device 10.

[0108] When an external impact is applied to the display device 10 in the +x-axis direction, the protrusion 210 may move. Therefore, the coupling device 1000 may move in the -x-axis direction relative to the protrusion 210.

[0109] When the intensity (e.g., force) of the external impact applied to the display device 10 is relatively small, the deformable portion 212 can be deformed by receiving the external force through the fastening device, and the fastening device inserted into the first unit 2115 can be placed after moving from the original fastening position along the -x-axis direction.

[0110] When the intensity of the external impact (e.g., external force) applied to the display device 10 is relatively large, the deformable portion 212 may be damaged by receiving the external force through the fastening device, and the fastening device inserted into the first unit 2115 may be moved along the -x-axis direction and may be at least partially placed in the second unit 2116.

[0111] The deformable portion 212 does not receive external impact but is deformed or damaged by the external impact to mitigate the impact applied to the display device 10. Therefore, it is preferable to appropriately design the thickness and width of the deformable portion 212 so that deformation or damage occurs when an external impact having a strength equal to or greater than a certain strength is applied.

[0112] In one embodiment, the fastening hole 211 may be composed of a first unit 2115 and a second unit 2116 separated from each other by a deformable portion 212, and the deformable portion 212 may be deformed or damaged when an external impact is applied to the display device 10 to buffer the impact applied to the display device 10, thereby effectively suppressing damage to the display device 10.

[0113] A plurality of protrusions 210 may be formed on each of the rear cover 200, the first bracket 220, and the second bracket 230, and a fastening hole 211 having a diameter D1 in the first direction greater than a diameter D2 in the second direction may be defined in each protrusion 210. Such protrusions 210 may be arranged to be spaced apart from each other in the third direction, that is, the lateral direction of the display device 10.

[0114] Therefore, when only a portion to which an external impact is applied is viewed in the third direction, the protrusion 210 provided only in the portion to which the external impact is applied may move in the first direction, thereby being placed at a position different from its original position. In this case, the arrangement posture and shape may become different only in a portion of the display device 10.

[0115] In one example, when an external impact is applied to the entire display apparatus 10 , all protrusions 210 provided on the display apparatus 10 may move in the first direction, so that the arrangement posture and shape of the entire display apparatus 10 may be changed.

[0116] In this way, the arrangement posture and shape of part or all of the display device 10 may become different due to external impact, but the protrusion 210 moves to buffer the external impact, thereby effectively suppressing damage to the display device 10 caused by the external impact.

[0117] In one example, unless Figure 9 Otherwise, when the arrangement posture and shape are changed due to external impact, the normal arrangement posture and shape of the display device 10 can be restored by loosening the connecting device 1000 again to return the display device 10 to its original position and then tightening the connecting device 1000 again.

[0118] In an embodiment, when an external impact is applied, the protrusion 210 provided on the display device 10 can move to suppress the external impact, thereby suppressing damage to the display device 10. Therefore, the durability of the display device 10 can be improved, and the safety of the user can be improved by suppressing the fragments generated by the damage of the display device 10 from injuring the user.
