Description

[0001] This application claims priority to Korean Patent Application No. 10-2024-0196842, filed on December 26, 2024, with the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference. Technical Field

[0002] This disclosure relates to a display device, and more particularly to a display device with improved durability. Background Technology

[0003] Currently, as we enter the era of comprehensive information, the field of display devices that visually express electrical information signals has developed rapidly and continues to be researched to improve the performance of various display devices, such as reducing thickness, light weight and low power consumption.

[0004] Among various display devices, light-emitting displays are self-emitting (or light-emitting) devices, which eliminate the need for a separate light source, unlike liquid crystal displays. Therefore, light-emitting displays can be manufactured with a light weight and small thickness. Furthermore, because light-emitting displays are driven by low voltage, they offer advantages not only in terms of power consumption but also in terms of color reproduction, response speed, viewing angle, and contrast ratio (CR). Therefore, they are expected to be used in a wide range of fields.

[0005] At the same time, especially in the case of mobile display devices, the display panel, which is part of the mobile display device, may be damaged due to external impacts, which may seriously affect the display quality of the mobile display device. Summary of the Invention

[0006] The purpose of this disclosure is to provide a display device that can effectively absorb externally applied shocks and pressures to protect the display panel of the display device.

[0007] Another objective of this disclosure is to provide a display device that minimizes the breakage or separation of the display panel of the display device when an impact is applied to the display device, thereby improving the lifespan of the display device.

[0008] The purpose of this disclosure is not limited to the above-described purposes, and other purposes not mentioned above will be clearly understood by those skilled in the art from the following description.

[0009] To achieve the objectives described above, according to one aspect of this disclosure, a display device includes: a cover window; a display panel disposed below the cover window; a deformable member (e.g., a molded member, but not limited thereto) disposed on the side of the display panel; and a linkage assembly, which is at least partially disposed between the side surface of the display panel and the deformable member to absorb impacts applied to the display panel from the outside.

[0010] Further details of the exemplary embodiments are included in the detailed description and accompanying drawings.

[0011] According to this disclosure, when external impacts and pressures are applied, the generation of cracks in the display panel can be minimized, thereby minimizing damage to the components of the display device.

[0012] According to this disclosure, the linkage assembly is disposed between the cover window and the display panel and is configured to elastically support the deformable member (e.g., the molded member) in response to deformation, thereby effectively protecting the display panel from external impacts or pressure. Therefore, the durability of the display device is improved and the defect rate is reduced. Furthermore, the lifespan of the display device is increased, maintenance costs are reduced, and user reliability is enhanced, thereby strengthening market competitiveness.

[0013] The effects of this disclosure are not limited to those illustrated above, and many more effects are included in this disclosure. Attached Figure Description

[0024] In the following, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0026] Figure 2 It is along Figure 1 The cross-sectional view taken from AA′.

[0029] Figure 5 This is a view showing the state of a display device according to a first exemplary embodiment of the present disclosure, after an external impact has occurred, returning to its initial state.

[0030] Figure 2 and Figure 3 They are shown separately. Figure 1 A cross-sectional view and perspective view of a corner portion (or corner) on one side (e.g., the upper side) of the display device 100. In this case, the upper side may refer to the portion (or side) in which the printed circuit board is disposed.

[0031] exist Figures 2 to 5 For ease of description, housing 150 is not shown.

[0032] First, refer to Figures 1 to 5 The display device 100 according to an exemplary embodiment of the present disclosure may include a cover window 110, a display panel 120, a molded (or shaped) member 130 as a deformable member, and a linkage assembly 140. Furthermore, the display device 100 according to a first exemplary embodiment of the present disclosure may also include a housing 150.

[0033] The cover window 110 may be a component exposed to the outer periphery of the display device 100 and protecting the display device 100 from external impacts or scratches. In addition, the cover window 110 can protect the display device 100 from moisture penetration from the outside.

[0034] The cover window 110 may be made of glass or a flexible plastic material, but is not limited to these.

[0035] The display panel 120 can be positioned below the cover window 110.

[0036] For example, the display panel 120 may include an adhesive layer 121, a polarizing plate 122, a first adhesive 123, a main panel 124, a second adhesive 125, a back panel 126, a third adhesive 127, and a metal plate 128.

[0037] The adhesive layer 121 can be disposed between the polarizing plate 122 and the cover window 110.

[0038] The adhesive layer 121 can be combined with the cover window 110 and the polarizing plate 122.

[0039] The adhesive layer 121 can be formed of a transparent material, making the image on the main panel 124 visible. In this case, for example, the adhesive layer 121 can be formed of an optically clear adhesive (OCA), but is not limited thereto.

[0040] The polarizing plate 122 can be disposed between the cover window 110 and the main panel 124. The polarizing plate 122 can be disposed between the adhesive layer 121 attached to the cover window 110 and the first adhesive 123 attached to the main panel 124.

[0041] The polarizing plate 122 reduces the reflection of external light incident on the main panel 124. Specifically, the main panel 124 may include various metallic materials applied to semiconductor elements, wiring, and organic light-emitting diodes. Therefore, external light incident on the main panel 124 can be reflected from the metallic materials, and the visibility of the display panel 120 may be reduced due to the reflection of external light. Conversely, when the polarizing plate 122 is provided, it suppresses the reflection of external light, thereby increasing the outdoor visibility of the display panel 120.

[0042] In this case, the first adhesive 123 is disposed between the polarizing plate 122 and the main panel 124 to bond the polarizing plate 122 and the main panel 124.

[0043] The first adhesive 123 may be formed of a transparent material, making the image on the main panel 124 visible. The first adhesive 123 may be formed of an optically clear adhesive (OCA), but is not limited thereto.

[0044] Main panel 124 is the panel used to display images to the user.

[0045] In the main panel 124, display elements for displaying images, driving elements for driving display elements, and wiring for transmitting various signals to display elements and driving elements can be set.

[0046] The display element can be defined in different ways depending on the type of the main panel 124. If the main panel 124 is an organic light-emitting panel, the display element can be an organic light-emitting diode including an anode, an organic emitting layer, and a cathode. If the main panel 124 is a liquid crystal display panel, the display element can be a liquid crystal display element.

[0047] In the following description, although the main panel 124 will be described by assuming that it is an organic light-emitting panel, the main panel 124 is not limited to an organic light-emitting panel.

[0048] The main panel 124 may include a substrate, pixel units, and an encapsulation layer.

[0049] The substrate is a base component supporting the various parts of the main panel 124 and may be constructed (or configured) of an insulating material. The substrate may be formed of a flexible plastic material. The substrate may be formed of a plastic material such as polyimide (PI), but is not limited thereto.

[0050] A pixel unit may include multiple organic light-emitting diodes and circuitry for driving the organic light-emitting diodes.

[0051] Depending on the emission direction of the light emitted from the organic light-emitting diode, the main panel 124 can be configured as either a top-emission type or a bottom-emission type.

[0052] Depending on the top-emitting type, light emitted from an organic light-emitting diode (OLED) is directed onto the top of the substrate on which the OLED is formed. In the case of the top-emitting type, a reflective layer can be formed below the anode to allow light emitted from the OLED to travel towards the upper portion of the substrate, i.e., towards the cathode.

[0053] Depending on the bottom-emitting type, light emitted from the organic light-emitting diode (OLED) is projected onto a substrate, forming the lower portion of the OLED. In the case of the bottom-emitting type, the anode can be formed solely of a transparent conductive material, and the cathode can be formed of a metallic material with high reflectivity, allowing light emitted from the OLED to travel beneath the substrate.

[0054] In the following description, the display device 100 according to the first exemplary embodiment of the present disclosure will be described by way of assumption that it is a top-emitting type, but is not limited thereto.

[0055] The encapsulation layer can be configured to cover the pixel unit. The encapsulation layer can seal the organic light-emitting diode (OLED) of the pixel unit. The encapsulation layer can protect the OLED of the pixel unit from moisture, oxygen, or external shock. The encapsulation layer can be formed by alternately laminating multiple inorganic layers and multiple organic layers. For example, the inorganic layers can be formed from inorganic materials such as silicon nitride (SiNx), silicon oxide (SiOx), and aluminum oxide (AlOx), and the organic layers can be formed from epoxy resin or acrylic polymers, but they are not limited to these.

[0056] A second adhesive 125 is disposed between the main panel 124 and the back panel 126 to bond the main panel 124 and the back panel 126. The second adhesive 125 may be formed of pressure-sensitive adhesive (PSA), but is not limited thereto.

[0057] The back panel 126 can support the main panel 124. When the substrate of the main panel 124 is formed of a plastic material such as polyimide, due to its flexible properties, a separate component may be needed to protect the substrate. Therefore, the back panel 126 for supporting the substrate can be disposed below the main panel 124.

[0058] The backsheet 126 may include a plastic material. The backsheet 126 may be formed from a plastic film made of polyimide (PI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), or a combination of these polymers.

[0059] For example, a third adhesive 127 is disposed between the back panel 126 and the metal plate 128 to bond the back panel 126 and the metal plate 128. The third adhesive 127 may be formed of a pressure-sensitive adhesive (PSA), but is not limited thereto.

[0060] The metal plate 128 protects the components of the display device 100 from external impacts. Furthermore, the metal plate 128 acts as a ground wire (in other words, a grounding element) to prevent static electricity from entering the display device 100 or to easily discharge residual charge accumulated in the display device 100 to the outside. The metal plate 128 can easily dissipate heat generated in the display device 100 to the outside. The metal plate 128 can be formed of a metallic material with excellent thermal conductivity, electrical conductivity, and mechanical rigidity. For example, the metal plate 128 can be constructed of copper (Cu) or stainless steel (SUS), but is not limited to these.

[0061] Foam component 160 may be disposed below metal plate 128. Foam component 160 may be used to prevent resin from entering or penetrating into display panel 120 before the resin cures during the process of injecting resin into molding component 130.

[0062] For example, a fourth adhesive 129 is disposed between the foam member 160 and the metal plate 128 to bond the foam member 160 and the metal plate 128. For example, the fourth adhesive 129 may be formed of a pressure-sensitive adhesive (PSA), but is not limited thereto.

[0063] The molded component 130 is disposed below the cover window 110 and may be spaced apart from the side portion (or side surface) of the display panel 120. The molded component 130 may seal the cover window 110, the display panel 120, and the linkage assembly 140. Furthermore, the linkage assembly 140 may be movably mounted in the molded component 130.

[0064] The molded component 130 can prevent moisture or oxygen from penetrating into the display panel 120. The molded component 130 can protect the components of the display device 120 and reduce the impact applied to the display panel 120.

[0065] In this case, for example, the molded component 130 may be formed from one or more materials selected from acrylic resin, epoxy resin, phenolic resin, polyamide resin, polyimide resin, unsaturated polyester resin, polyphenylene resin, polyphenylene sulfide resin and benzocyclobutene, but is not limited thereto.

[0066] In addition, a space S1 can be formed between the molded component 130 and the side portion of the display panel 120 spaced apart from it.

[0067] Space S1 can form a sealed structure.

[0068] Specifically, the upper portion of space S1 can be shielded by cover window 110, one side portion of space S1 can be shielded by display panel 120, and the lower portion and another side portion of space S1 can be shielded by molding component 130. In space S1, a second plate 142a (described below) can be movably disposed.

[0069] The link assembly 140 can absorb and disperse external impacts applied to the molded member 130.

[0070] The linkage assembly 140 can elastically support the molded member 130 in response to movement (i.e. deformation) of the molded member 130 toward the display panel 120 (i.e., pointing toward the display panel 120).

[0071] For example, when an impact is applied to the molded member 130, the linkage assembly 140 can ensure that the impact absorption time is as long as the time the molded member takes to move toward the display panel 120 (i.e., while moving toward the display panel 120). Furthermore, for example, the external impact is not transmitted directly from the molded member 130 to the display panel 120 via the linkage assembly 140, but rather the linkage assembly 140 can provide time for the molded member 130 to absorb the impact.

[0072] Linkage assembly 140 may be located at a corner of display device 100 (and therefore at a corner of display panel 120). For example, linkage assembly 140 may be located at a lower corner of display device 100. Multiple linkage assemblies 140 (e.g., at least three linkage assemblies 140) may be located at the corner (see [reference]). Figure 1 However, this disclosure is not limited to the number of linkage assemblies 140. For example, if the mobile display device falls to the ground, the corner may receive the greatest impact. Therefore, linkage assemblies 140 can be positioned at the corners of the display device 100 to effectively mitigate the impact.

[0073] The linkage assembly 140 may include a first linkage unit 141, a second linkage unit 142, a third linkage unit 143, a first shaft 144, a second shaft 145, and a third shaft 146.

[0074] The first link unit 141 can be connected to the end portion of the molded member 130. Specifically, as from... Figure 2 As can be seen, the first linkage unit 141 can be connected to the end portion of the molded member 130 relative to a first direction (in other words, in the first direction). The first linkage unit 141 can move toward the display panel 120 together with (or in conjunction with) the deformation of the molded member 130.

[0075] The first linkage unit 141 may include a first plate 141a and a first rod 141b.

[0076] The first plate 141a absorbs (or disperses) external impacts (and pressures) applied to the molding member 130. The first plate 141a may be disposed on the end portion of the molding member 130. The first plate 141a may be perpendicular to a first direction (see...). Figure 2 Extend in the direction of (hereinafter referred to as the second direction).

[0077] The first plate 141a may include an elastic material. For example, the first plate 141a may be a rubber structure formed from ethylene propylene diene monomer (EPDM), polyurethane (PU), or a combination of these polymers, but this disclosure is not limited thereto.

[0078] When the molded component 130 deforms due to an external impact, the first plate 141a moves together with the molded component 130 toward the display panel 120 to absorb (and disperse) the impact energy applied to the molded component 130.

[0079] The first rod 141b may be movably disposed in the molded member 130. For example, one side of the first rod 141b may be fixed to the first plate 141a, and the other side of the first rod 141b may be rotatably connected to the first shaft 144. The first rod 141b may extend in a first direction.

[0080] For example, the first lever 141b can move toward the display panel 120 along with the movement of the first plate 141a, and cause the third lever 143b to rotate toward the display panel 120 (i.e., pivot).

[0081] Furthermore, a portion of the second linkage unit 142 may be disposed in the sealed space S1 between the molding member 130 and the side portion of the display panel 120, and another portion of the second linkage unit 142 may be disposed in the molding member 130. The second linkage unit 142 may be rotatably connected to the first linkage unit 141 and the third linkage unit 143 via the first shaft 144.

[0082] The second linkage unit 142 may include a second plate 142a and a second rod 142b.

[0083] The second plate 142a can be configured to move horizontally within the sealed space S1. The second plate 142a can be rotatably connected to the second rod 142b via the second shaft 145.

[0084] The second plate 142a may include a center plate CP and an end plate EP.

[0085] The center plate CP can be positioned at the center of space S1 relative to the second direction (in other words, in the second direction). The center plate CP can be rotatably connected to the second rod 142b via the second shaft 145.

[0086] Furthermore, the center plate CP may include a recess H1 recessed inward on the side opposite to the main panel 124. For example, the main panel 124 may be inserted into the recess H1, and the inner surface of the center plate CP forming the recess H1 may contact the side surface of the main panel 124. As another example, a polarizing plate 122, a first adhesive 123, a main panel 124, a second adhesive 125, and a back plate 126 may be inserted into the recess H1.

[0087] Furthermore, the end plate EP can be disposed in the two side portions of the space S1 relative to the second direction (in other words, in the second direction). The end plate EP can extend from both sides of the center plate CP along the second direction. The end plate EP can contact the side surface of the adhesive layer 121 and the side surface of the metal plate 128 (and the third adhesive 127).

[0088] The second plate 142a can contact the side portion of the display panel 120 while moving toward the display panel 120 via the first linkage unit 141. The second plate 142a is located between the display panel 120 and the molding member 130 to act as a cushioning material. Therefore, the molding member 130 is prevented from making direct contact with the display panel 120 to suppress the formation of cracks in the display panel 120 due to the molding member 130.

[0089] Furthermore, the second plate 142a, along with the operation of the first linkage unit 141 and the third linkage unit 143, can move toward the side portion of the display panel 120 to make contact with it. In this case, the second plate 142a may be affected by the resistance caused by the fluid in the sealed space S1 between the molding member 130 and the side portion of the display panel 120. When the second plate 142a moves, the resistance generated by the fluid dissipates the impact energy transmitted from the first linkage unit 141, so that the impact that will be transmitted to the display panel 120 through the second plate 142a can be partially absorbed.

[0090] The second rod 142b is movably disposed within the molded component 130. One side of the second rod 142b is rotatably connected to the first link unit 141 and the third link unit 143 via the first shaft 144. The other side of the second rod 142b is rotatably connected to the second plate 142a via the second shaft 145. The second rod 142b can extend in a first direction.

[0091] The second rod 142b can move toward the display panel 120 along with the movement of the first rod 141b, and push the second plate 142a toward the display panel 120. For example, the second rod 142b can be rotatably supported on (or connected to) the third rod 143b via the first shaft 144 to form a gradient arrangement (or tilted configuration), wherein, along with the pivoting operation of the third rod 143b, one side of the second rod 142b (i.e., the portion connected to the third rod 143b) is positioned higher, and the other side of the second rod 142b (i.e., the portion connected to the first rod 141b) is positioned lower. As described above, while forming the gradient arrangement, resistance is applied to the second rod 142b via the molding member 130, and the impact energy transmitted from the first linkage unit 141 can be partially dissipated by the resistance of the molding member 130.

[0092] The third link unit 143 is connected to the first link unit 141 and the second link unit 142 to provide restoring force to the first link unit 141 and the second link unit 142. The third link unit 143 can be rotatably connected to the first link unit 141 and the second link unit 142 via the first shaft 144.

[0093] For example, the third link unit 143 may include a link housing 143a, a third link 143b, and a support bushing 143c.

[0094] The connecting rod housing 143a can be attached to the cover window 110.

[0095] The side portion of the connecting rod housing 143a can be supported by the molded component 130.

[0096] The connecting rod housing 143a may include a receiving space S2. A support bushing 143c and a third rod 143b may be disposed within the receiving space S2.

[0097] The connecting rod housing 143a may include a through hole H2 communicating with the receiving space S2 below it. The third shaft 146 may be located in the receiving space S2 of the connecting rod housing 143a, and the third rod 143b may be disposed in the through hole H2.

[0098] Although not shown, the inner surface of the connecting rod housing 143a forming the through hole H2 can be inclined upward from the lower side to the upper side. The pivoting third rod 143b can contact the upwardly inclined inner surface of the through hole H2 for support.

[0099] The third link 143b can be rotatably mounted in the link housing 143a, allowing it to rotate within a predetermined angle range, and can be rotatably connected to the first link unit 141. The third link 143b can pivot with a rotation axis (i.e., a rotation axis formed by the third axis 146) formed in the link housing 143a.

[0100] The third link 143b is rotatably connected to the third shaft 146 and passes through the through hole H2 to protrude downward from the link housing 143a and is elastically supported by the support bushing 143c. The third link 143b can be rotated (i.e., pivoted) by the movement of the first link unit 141.

[0101] In the following text, an example will be described in which the pivoting direction of the third link 143b driven by the first link unit 141 is clockwise, and an example will be described in which the third link 143b returns to its initial position through the support bushing 143c in a counterclockwise direction.

[0102] The third rod 143b may include a first rod portion B1 and a second rod portion B2.

[0103] The first rod portion B1 can be disposed in the receiving space S2 and can be rotatably supported on the third shaft 146. The lower edge portion of the first rod portion B1 can be formed into an arc-shaped (or rounded) surface. When the third rod 143b pivots, the arc-shaped surface of the first rod portion B1 can contact the upper portion of the support bushing 143c.

[0104] The second rod portion B2 may be formed to extend downward from the first rod portion B1. A portion of the second rod portion B2 may be located in the receiving space S2 and the through hole H2, and another portion of the second rod portion B2 may protrude outward from the connecting rod housing 143a to be disposed in the molding member 130.

[0105] The upper portion of the second rod portion B2 is inserted into the insertion hole H3 of the support bushing 143c and can be elastically supported on the inner surface of the support bushing 143c forming the insertion hole H3. The lower portion of the second rod portion B2 can be rotatably connected to the first rod 141b via the first shaft 144.

[0106] The third link 143b can pivot toward the display panel 120 via the impact energy transmitted from the first link unit 141. The third link 143b can be elastically supported by the support bushing 143c during pivoting, and the impact energy can be converted into heat energy by the elastic force of the support bushing 143c for dissipation.

[0107] At least a portion of the support bushing 143c may be disposed between the connecting rod housing 143a and the third rod 143b and elastically support the third rod 143b.

[0108] The two sides of the support bushing 143c can be supported on the inner surface of the connecting rod housing 143a that forms the receiving space S2, and a portion of the lower part of the support bushing 143c can be supported by the inner surface of the connecting rod housing 143a that forms the through hole H2.

[0109] A jack H3 passing through the support bushing 143c in the second direction can be formed in the central portion of the support bushing 143c.

[0110] The second rod portion B2 of the third rod 143b can be inserted into the socket H3. With the third rod 143b inserted into the socket H3, the outer surface of the second rod portion B2 contacts the inner surface of the support bushing 143c forming the socket H3. In doing so, the support bushing 143c elastically supports the third rod 143b.

[0111] Furthermore, the diameter of the socket H3 can be smaller than the diameter of the through hole H2. The diameter of the socket H3 is formed to be smaller than the diameter of the through hole H2, so that when the third rod 143b is inserted into the socket H3 and supported by the support bushing 143c, the third rod 143b can pivot inside the through hole H2.

[0112] The support bushing 143c may be formed of an elastic material to elastically support the third rod 143b. The support bushing 143c may include an elastic material. For example, the support bushing 143c may be made of rubber formed from ethylene propylene diene monomer (EPDM), polyurethane (PU), or combinations of these polymers, but this disclosure is not limited thereto.

[0113] The support bushing 143c can be formed as a circular plate with a penetrating central portion (i.e., forming the insertion hole H3). For example, the support bushing 143c can be formed as a disc.

[0114] Furthermore, the diameter (in other words, the outer diameter) of the support bushing 143c can be equal to or greater than the diameter of the accommodating space S2. By doing so, the support bushing 143c can be coupled to the connecting rod housing 143a for a forced fit, and can be more securely coupled to the connecting rod housing 143a.

[0115] The support bushing 143c can elastically support the pivoting third rod 143b while elastically deforming, and dissipating a portion of the impact energy transmitted from the third rod 143b during elastic deformation. Furthermore, the support bushing 143c can return the third rod 143b to its initial position by means of the elastic force generated during elastic deformation.

[0116] The first shaft 144 can be set in the molded component 130.

[0117] The first axis 144 extends upward in a third direction perpendicular to the first and second directions (see...). Figure 2 It can be rotatably connected to the lower part of the third rod 143b. In addition, the first shaft 144 can rotatably connect the first rod 141b, the third rod 143b and the second rod 142b to each other.

[0118] The second shaft 145 can extend upwards to a third party and rotatably connect the second plate 142a and the second rod 142b to each other.

[0119] The third shaft 146 can be installed in the connecting rod housing 143a.

[0120] The third axis 146 can be in a direction perpendicular to the first direction (i.e., the third direction, see...). Figure 2 The third shaft 146 extends horizontally. The two side portions of the third shaft 146 can be rotatably connected to the connecting rod housing 143a.

[0121] Meanwhile, the housing 150 can cover the side portion of the molded component 130.

[0122] The housing 150 may be disposed on the side surface of the cover window 110 and the side and bottom surfaces of the molded member 130. The housing 150 covers the cover window 110 and the molded member 130 to protect the cover window 110 and the molded member 130.

[0123] The inner surface of the housing 150 may be bonded to the molding member 130. A portion of the inner surface of the housing 150 may be bonded to the molding member 130. The housing 150 is bonded to the molding member 130 to cover the side and bottom surfaces of the molding member 130. A housing adhesive layer (not shown) may be provided between the inner surface of the housing 150 and the molding member 130. The housing adhesive layer may be provided between the inner surface of the housing 150 and the molding member 130 to bond the inner surface of the housing 150 and the molding member 130, but this disclosure is not limited thereto.

[0124] The housing 150 may be formed of a material having a predetermined rigidity to protect the side surfaces of the cover window 110 and the molded member 130. For example, the housing 150 may be formed of a plastic formed from any of polyimide (PI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), and combinations of these polymers, or a metal such as copper (Cu) or stainless steel (SUS), but is not limited thereto.

[0125] The following will describe a series of processes by which the link assembly 140 absorbs the impact applied to the molded member 130 and returns to its initial position after absorbing the impact.

[0126] First, refer to Figure 2 and Figure 4 When an impact is applied to the molding member 130, the first plate 141a and the first rod 141b can move toward the display panel 120. The first rod 141b can transfer the impact energy to the second rod 142b and the second plate 142a via the first shaft 144, and the first plate 141a, the first rod 141b, the second rod 142b, and the second plate 142a can move toward the display panel 120 together with the molding member 130. Furthermore, as the first plate 141a, the first rod 141b, the second rod 142b, and the second plate 142a move together with the molding member 130, an impact absorption time can be ensured to delay the transmission of external impact energy to the display panel 120.

[0127] Therefore, more time is ensured for the molded component 130 to absorb and dissipate impact energy. Furthermore, the linkage assembly 140 can absorb and dissipate impact energy simultaneously with the process of absorbing impact energy through the molded component 130.

[0128] First, the second plate 142a receives impact energy through the first plate 141a, the first rod 141b, and the second rod 142b, so as to move in the space S1 along a first direction. At this time, the second plate 142a can receive resistance caused by the fluid in the sealed space S1. That is, the resistance may be generated by air braking phenomenon when the second plate 142a moves. The resistance generated by the fluid when the second plate 142a moves can dissipate the impact energy transmitted from the first linkage unit 141, so that the impact transmitted to the display panel 120 through the second plate 142a can be eliminated.

[0129] Furthermore, the third link unit 143 can receive impact energy through the first plate 141a and the first link 141b. The third link 143b can pivot clockwise through the first link 141b and the first shaft 144. The third link 143b can be elastically supported by the support bushing 143c during pivoting, and the impact energy can be converted into heat energy by the elasticity of the support bushing 143c for dissipation.

[0130] As described above, the impact energy applied to the molded member 130 can be absorbed and dissipated by factors that increase the impact absorption time of the molded member 130 when the connecting rod assembly 140 moves together with the molded member 130, by drag factors generated when the second plate 142a moves in space S1, and by elastic factors generated when the support bushing 143c elastically deforms through the third rod 143b.

[0131] In addition, external impact energy can also be absorbed and dissipated by the elasticity of each of the first rod 141b, the second rod 142b, and the third rod 143b.

[0132] Next, refer to Figure 4 and Figure 5 The link assembly 140 can return to its initial position, which is the position before the link assembly 140 moved, by the elastic restoring force generated when the support bushing 143c elastically deforms.

[0133] First, the third rod 143b can pivot counterclockwise by the elastic restoring force of the support bushing 143c. The second rod 142b and the second plate 142a can move away from the display panel 120 (i.e., in the opposite direction to the first direction) together with the pivoting of the third rod 143b. The movement of the second rod 142b away from the display panel 120 pushes the first rod 141b and the first plate 141a, allowing the first plate 141a to return to its initial position. When the first plate 141a returns to its initial position, the molded member 130 can also return to its initial position (i.e., the position before the impact).

[0134] Figure 6 This is a cross-sectional view of a display device according to a second exemplary embodiment of the present disclosure.

[0135] Figure 7 This is a view showing the state of an external impact occurring in a display device according to a second exemplary embodiment of the present disclosure.

[0136] Except for forming the connecting slit LS in the third link 143b and not providing the second shaft 145 (and in this case, the second link 142b can be directly connected to the second plate 142a), Figure 6 and Figure 7 The display device 200 of the second exemplary embodiment and Figures 1 to 5 The display device 100 described in the first exemplary embodiment is substantially the same as that described above, therefore redundant descriptions will be omitted. Furthermore, identical configurations will be indicated by the same reference numerals. A description of the same reference numerals can be found by referring to... Figures 1 to 5 .

[0137] Reference Figure 6 and Figure 7 The display device 200 according to the second exemplary embodiment of the present disclosure may further include a link slit LS.

[0138] For example, the connecting rod slit LS can be formed to pass through the third rod 143b in a third direction at the lower end of the third rod 143b (i.e., the second rod portion B2). The connecting rod slit LS can be formed at the lower end of the third rod 143b with a predetermined length (in particular, a predetermined length in the second direction).

[0139] The first shaft 144 can be inserted into the connecting rod slit LS. The first shaft 144 can move along the connecting rod slit LS, which is formed with a predetermined length. For example, when the third rod 143b is positioned parallel to the second direction, the first shaft 144 can be positioned on the opposite lower side of the connecting rod slit LS. Conversely, when the third rod 143b is rotated clockwise, the first shaft 144 can be positioned on the opposite upper side of the connecting rod slit LS.

[0140] When an impact is applied to the molded member 130, in the display device 200 of the second exemplary embodiment, the first linkage unit 141 can move toward the display panel 120. The third link 143b can pivot clockwise along with the movement of the first linkage unit 141, and the second link 142b and the second plate 142a can move horizontally in a first direction along with the pivoting of the third link 143b. At this time, the position of the first axis 144 can change from the lower side of the linkage slit LS to the upper side of the linkage slit LS while moving along the linkage slit LS. As the first axis 144 moves along the linkage slit LS, the impact absorption time of the molded member 130 increases, and the molded member 130 can absorb more external impact energy over time. This means that the impact energy absorbed by the molded member 130 before the external impact energy is transmitted from the molded member 130 to the display panel 120 increases.

[0141] In the display device 200 according to a second exemplary embodiment of the present disclosure, the second rod 142b moves horizontally in a first direction via the connecting rod slit LS, allowing the second plate 142a to receive greater resistance from the fluid in the sealed space S1. The impact absorption time is increased by the resistance of the fluid, thereby increasing the impact energy absorbed by the molded member 130.

[0142] Figure 8 This is a cross-sectional view of a display device according to a third exemplary embodiment of the present disclosure.

[0143] Figure 9 This is a view showing the state of an external impact occurring in a display device according to a third exemplary embodiment of the present disclosure.

[0144] In addition to the second link unit 142, it also includes the pad PA. Figure 8 and Figure 9 The display device 300 of the third exemplary embodiment and Figures 1 to 5 The display device 100 described in the first exemplary embodiment is substantially the same as that described above, therefore redundant descriptions will be omitted. Identical configurations will be indicated by the same reference numerals. A description of the same reference numerals can be found by referring to... Figures 1 to 7 .

[0145] Reference Figure 8 and Figure 9 The display device 300 according to the third exemplary embodiment of the present disclosure may further include a pad PA.

[0146] The pad PA can be disposed in the groove H1 of the second plate 142a, opposite to the display panel 120. The pad PA can be disposed in the center plate CP.

[0147] For example, the length of the pad PA in the second direction can be formed to be the same as the height of the polarizer 122, the main panel 124 and the back panel 126 stacked together.

[0148] The liner PA can be formed from an elastic material. The liner PA can be a rubber structure formed from ethylene propylene diene monomer (EPDM), polyurethane (PU), or a combination of these polymers, but this disclosure is not limited thereto.

[0149] When an impact is applied to the molded member 130, in the display device 300 of the third exemplary embodiment, the first linkage unit 141 can move toward the display panel 120. The second linkage unit 142 can move toward the display panel 120 along with the movement of the first linkage unit 141 and the third linkage unit 143. A pad PA attached to the second plate 142a can contact the display panel 120. The pad PA serves as a buffer material between the display panel 120 and the second linkage unit 142 to absorb the impact energy that will be transmitted to the display panel 120.
