[0032] Features of various embodiments of this disclosure may be partially or wholly bonded or combined with each other, and may be interlocked and operated in various technical ways, and these embodiments may be performed independently or in relation to each other.

[0033] In the following, a display device according to exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0034] Figure 1 This is an exploded perspective view of a display device according to an exemplary embodiment of the present disclosure.

[0035] refer to Figure 1 The display device 1000 according to an exemplary embodiment of the present disclosure includes a cover window 100, a touch glass 200, an adhesive layer AD, a polarizing layer 300, a display panel 400, and a support layer 500. It should be noted that... Figure 1 The diagram illustrates a first direction DR1, a second direction DR2, and a third direction DR3 that are orthogonal to each other. In an embodiment, the cover window 100, touch glass 200, adhesive layer AD, polarizing layer 300, display panel 400, and support layer 500 can be sequentially stacked along the third direction DR3, as shown below. Figure 1 As shown.

[0036] A cover window 100 is disposed above the display device 1000. The cover window 100 is configured to correspond to the display panel 400 to protect the display panel 400 from external impacts, moisture and heat.

[0037] Touch glass 200 is disposed on the rear surface of cover window 100. Touch glass 200 converts the touch position of a user's hand or object directly touching the cover into an electrical signal, and can input the command selected at the touch position as an input signal.

[0038] Touch glass 200 may include a touch screen panel. Mutual capacitance with multiple intersecting driving electrodes and multiple sensing electrodes can be applied to the touch screen panel, but the touch screen panel is not limited to this and can be implemented in various ways, such as self-capacitance.

[0039] An adhesive layer AD, which secures the touch glass 200 and the polarizing layer 300, is disposed on the rear surface of the touch glass 200 and located between the touch glass 200 and the polarizing layer 300. The adhesive layer AD can be formed as an optically transparent adhesive (OCA), which minimizes foreign matter or air bubbles generated between the touch glass 200 and the polarizing layer 300. However, it is not limited to this, and the adhesive layer AD can be omitted according to an embodiment of the display device 1000.

[0040] The polarizing layer 300 can be disposed on the rear surface of the touch glass 200 via the adhesive layer AD. The polarizing layer 300 selectively transmits light to reduce the reflection of external light incident on the display panel 400, thereby suppressing the decrease in visibility of the display device 1000 due to light reflection. However, it is not limited to this, and the polarizing layer 300 may be omitted depending on the embodiment of the display device 1000.

[0041] The display panel 400 is disposed on the rear surface of the polarization layer 300. The display panel 400 is a panel used to display images to a user. The display panel 400 may contain light-emitting diodes (LEDs) for displaying images, driving elements for driving the LEDs, and wiring lines for transmitting various signals to the LEDs and driving elements.

[0042] The light-emitting diode (LED) can be defined in different ways depending on the type of display panel 400. For example, if display panel 400 is an organic light-emitting display panel, the LED can be an organic light-emitting diode that includes an anode, an organic emitting layer, and a cathode. In the following text, even if display panel 400 is assumed to be an organic light-emitting display panel, display panel 400 is not limited to organic light-emitting display panels. For example, display panel 400 can also be a liquid crystal display panel.

[0043] Meanwhile, even if not shown in the figure, multiple circuits for driving light-emitting diodes can be arranged on the display panel 400. For example, multiple flexible films and printed circuit boards can provide signals, such as power supply voltage or data voltage, to the light-emitting diodes of the display panel 400. Multiple flexible films can be arranged on one side of the display panel 400 along the second direction DR2, but are not limited thereto.

[0044] A support layer 500 is disposed on the rear surface of the display panel 400. The support layer 500 not only supports the display panel 400, but also protects the display panel 400 from external moisture, heat, and impact. The support layer 500 can be configured to have a shape corresponding to the display panel 400.

[0045] The following will refer to Figure 2 Detailed description of support layer 500.

[0046] Figure 2 This is an exploded perspective view of the support layer of a display device according to an exemplary embodiment of the present disclosure.

[0047] refer to Figure 2 The support layer 500 includes a first protective layer 510, a first heat dissipation layer 520, an adhesive pattern layer 530, a reinforcing member 540, a second heat dissipation layer 550, and a second protective layer 560. It should be noted that... Figure 2 The diagram also shows a first direction DR1, a second direction DR2, and a third direction DR3 that are orthogonal to each other. In an embodiment, the first protective layer 510, the first heat dissipation layer 520, the adhesive pattern layer 530, the reinforcing member 540, the second heat dissipation layer 550, and the second protective layer 560 can be sequentially stacked along the third direction DR3, as shown below. Figure 2 As shown.

[0048] A first protective layer 510 is disposed on the rear surface of the support layer 500. The first protective layer 510 is disposed on the rear surface of the display device 1000 to protect the display device 1000, and can be defined as a pad. The first protective layer 510 can be formed of polyethylene terephthalate (PET), but is not limited thereto.

[0049] A first heat dissipation layer 520 is disposed on the top surface of the first protective layer 510. The first heat dissipation layer 520 is configured to correspond to the first protective layer 510 and can be attached to the entire top surface of the first protective layer 510. The first heat dissipation layer 520 can be formed of a metallic material with high thermal conductivity. For example, the first heat dissipation layer 520 can be formed of a metal layer such as copper. Therefore, the first heat dissipation layer 520 can perform the heat dissipation function, grounding function, and protection function of the display panel 400.

[0050] An adhesive pattern layer 530 may be disposed on the top surface of the first heat dissipation layer 520. The adhesive pattern layer 530 may be configured to correspond to the reinforcement 540 and to attach the reinforcement 540 to the first heat dissipation layer 520. The adhesive pattern layer 530 may be formed of an optically clear adhesive (OCA), but is not limited thereto.

[0051] The reinforcing member 540 can be disposed on the top surface of the first heat dissipation layer 520 via an adhesive pattern layer 530. The reinforcing member 540 can support the display panel 400 disposed above the reinforcing member 540. The reinforcing member 540 can be formed of stainless steel (SUS), but is not limited thereto.

[0052] The reinforcing member 540 is configured to correspond to a portion of the display panel 400, but may not be configured to correspond to other portions of the display panel 400. For example, the display device 1000 may include a battery configured to correspond to other portions of the display panel 400. Therefore, the reinforcing member 540 may be disposed in an area other than the area where the battery is disposed. For example, the reinforcing member 540 may be configured to overlap with both ends of the display panel 400 in the second direction DR2, but may be configured not to overlap with both ends of the display panel 400 in the first direction DR1, but is not limited thereto. Reference will be made below. Figure 3 Detailed description of reinforcement component 540.

[0053] The second heat dissipation layer 550 is disposed on the top surface of the reinforcing member 540. The second heat dissipation layer 550 is configured to correspond to the second protective layer 560 and can be attached to the entire rear surface of the second protective layer 560. The second heat dissipation layer 550 can be formed of a material with high thermal conductivity, such as graphite or carbon nanotubes. For example, the second heat dissipation layer 550 can be formed of a graphite layer. Therefore, the second heat dissipation layer 550 can perform the heat dissipation function, grounding function, and protection function of the display panel 400.

[0054] The second protective layer 560 is disposed on the top surface of the second heat dissipation layer 550. The second protective layer 560 can protect the display panel 400 during the manufacturing process of the display device 1000. Therefore, the second protective layer 560 can be referred to as a protective film. The second protective layer 560 can be formed of polyethylene terephthalate (PET), but is not limited thereto.

[0055] Figure 3 This is a plan view of a reinforcement member of a display device according to an exemplary embodiment of the present disclosure.

[0056] refer to Figure 3 The reinforcing member 540 may include a plurality of first reinforcing members 541 extending in the first direction DR1 and a second reinforcing member 542 extending in the second direction DR2.

[0057] Each of the plurality of first reinforcing members 541 extends in the first direction DR1. For example, the plurality of first reinforcing members 541 may be disposed along one side of the display panel 400 that extends in the first direction DR1.

[0058] The plurality of first reinforcing members 541 may include a plurality of recessed patterns C recessed in the second direction DR2. In an embodiment, each of the plurality of first reinforcing members 541 may include a plurality of recessed patterns C recessed in the second direction DR2.

[0059] The plurality of recessed patterns C may include a plurality of first recessed patterns C1 and a plurality of second recessed patterns C2. A plurality of first protruding patterns E1 of the second reinforcing member 542, described below, are disposed in the plurality of first recessed patterns C1, and a plurality of second protruding patterns E2 are disposed in the plurality of second recessed patterns C2. For example, the plurality of second recessed patterns C2 may be positioned closer to the outer periphery of the display panel 400 than the plurality of first recessed patterns C1. In an embodiment, each first recessed pattern C1 is connected to a corresponding second recessed pattern C2. In this case, in the first direction DR1, the width W1 of the first recessed pattern C1 may be smaller than the width W2 of the second recessed pattern C2.

[0060] The plurality of first reinforcing members 541 may include first sub-reinforcing members 541a and second sub-reinforcing members 541b spaced apart from each other (i.e., two first reinforcing members opposite each other in the second direction), wherein a second reinforcing member 542 is located between the first sub-reinforcing members 541a and second sub-reinforcing members 541b. For example, the first sub-reinforcing members 541a and second sub-reinforcing members 541b may be configured to be opposite each other in the second direction DR2. In this case, each of the first sub-reinforcing members 541a and second sub-reinforcing members 541b may be configured such that a plurality of recessed patterns C of the first sub-reinforcing member 541a and a plurality of recessed patterns C of the second sub-reinforcing member 541b may be configured to be opposite each other.

[0061] The second reinforcing member 542 can be disposed between the first sub-reinforcing member 541a and the second sub-reinforcing member 541b. The second reinforcing member 542 can extend in the second direction DR2. For example, the second reinforcing member 542 can extend in the second direction DR2 and cross the center portion of the display panel 400.

[0062] Meanwhile, the second reinforcing member 542 can be configured to be spaced apart from the first sub-reinforcing member 541a and the second sub-reinforcing member 541b. For example, the second reinforcing member 542 can be configured to be spaced apart from the first sub-reinforcing member 541a and the second sub-reinforcing member 541b by a gap of approximately 0.2 mm, but is not limited thereto.

[0063] The second reinforcing member 542 may include a plurality of protruding patterns E. For example, the second reinforcing member 542 may include a plurality of protruding patterns E disposed in each of a plurality of recessed patterns C of a plurality of first reinforcing members 541. In an embodiment, the second reinforcing member 542 may include a plurality of protruding patterns E disposed opposite to each other at both ends of the second reinforcing member along a second direction DR2, i.e., at least a pair of protruding patterns, but not limited to this.

[0064] Multiple protruding patterns E can be disposed on one surface of the second reinforcement 542 opposite to the first sub-reinforcement 541a and on another surface of the second reinforcement 542 opposite to the second sub-reinforcement 541b.

[0065] Each of the plurality of protruding patterns E may include a first protruding pattern E1 disposed along the second direction DR2 and a second protruding pattern E2 connected to the first protruding pattern E1. For example, the second protruding pattern E2 may be disposed closer to the outer periphery of the display panel 400 than the first protruding pattern E1.

[0066] At this time, the plurality of protruding patterns E of the second reinforcing member 542 may have shapes corresponding to the recessed patterns C of the plurality of first reinforcing members 541. For example, in the first direction DR1, the width W3 of the first protruding pattern E1 may be smaller than the width W4 of the second protruding pattern E2.

[0067] Meanwhile, in the first direction DR1, the width W4 of the second protruding pattern E2 can be greater than the width W1 of the first recessed pattern C1, but smaller than the width W2 of the second recessed pattern C2. Therefore, the second protruding pattern E2 disposed in the second recessed pattern C2 can remain within the first direction DR1 and / or the second direction DR2. Thus, the plurality of first reinforcing members 541 and second reinforcing members 542 can be coupled to each other through the plurality of recessed patterns C and the plurality of protruding patterns E.

[0068] In the following text, reference will be made to Figures 4A to 5D The effect of the reinforcement 540 of the display device 1000 according to an exemplary embodiment of the present disclosure will be described.

[0069] Figures 4A to 4D This is a view used to explain the stress simulation results of the reinforcement of the display device according to an exemplary embodiment of the present disclosure. Figures 4A to 4D The results were obtained by measuring the stresses of the reinforcement S of the comparative embodiment and the reinforcement 540 of the exemplary embodiment when a ball is dropped in the comparative embodiment and the exemplary embodiment. The reinforcement 540 of the exemplary embodiment is the reinforcement 540 of the display device 1000 according to the exemplary embodiment of the present disclosure. The only difference between the reinforcement S of the comparative embodiment and the reinforcement 540 of the display device 1000 according to the exemplary embodiment of the present disclosure is that the plurality of recessed patterns C are not provided in the plurality of first reinforcements S1, and the plurality of protruding patterns E are not provided in the second reinforcements S2. Figure 4A The simulation results were obtained by measuring the stress of the reinforcement S in the comparative embodiment when the ball landed on the center portion of the second reinforcement S2 in the comparative embodiment. Figure 4B The simulation results were obtained by measuring the stress on the reinforcement 540 of the exemplary embodiment when the ball lands on the central portion of the second reinforcement 542 of the exemplary embodiment. Figure 4C The simulation results were obtained by measuring the stress of the reinforcement S in the comparative embodiment when the ball landed on the boundary portion of the plurality of first reinforcement S1 and second reinforcement S2 in the comparative embodiment. Figure 4D The simulation results were obtained by measuring the stress on the reinforcement 540 of the exemplary embodiment when a ball lands on the boundary portion of the plurality of first reinforcements 541 and second reinforcements 542. Figures 4A to 4D This means that the higher the density of points represented in a region, the higher the stress.

[0070] The following table 1 shows Figures 4A to 4B The maximum stress of the reinforcement S in the comparative embodiment and the maximum stress of the reinforcement 540 in the exemplary embodiment are shown.

[0071] [Table 1]

[0072] Comparative Examples Exemplary embodiments Maximum stress 40.55MPa 40.78MPa

[0073] refer to Figure 4A As a result of measuring the stress of the reinforcing member S in the comparative embodiment, it can be confirmed that the region A1 where the maximum stress is obtained is located in the central portion of the second reinforcing member S2. Furthermore, referring to Table 1, it can be confirmed that the maximum stress in the region A1 where the maximum stress is obtained in the reinforcing member S of the comparative embodiment is approximately 40.55 MPa.

[0074] Next, refer to Figure 4B As a result of measuring the stress of the reinforcing member 540 in the exemplary embodiment, it can be confirmed that the region A2 where the maximum stress is obtained is located in the central portion of the second reinforcing member 542. Furthermore, referring to Table 1, it can be confirmed that the maximum stress of the reinforcing member 540 in the region A2 where the maximum stress is obtained is approximately 40.78 MPa.

[0075] Therefore, it can be confirmed that the maximum stress generated in the reinforcing member 540 of the exemplary embodiment is greater than the maximum stress generated in the reinforcing member S of the comparative embodiment. At this time, Figure 4A and Figure 4B The stress referred to here is the stress applied to the reinforcement member during an impact applied to the display device. Therefore, this means that the reinforcement member 540 of the exemplary embodiment absorbs more impact than the reinforcement member S of the comparative embodiment. Thus, this means that when the same impact is applied to the reinforcement member S of the comparative embodiment and the reinforcement member 540 of the exemplary embodiment, the reinforcement member 540 of the exemplary embodiment absorbs more impact applied to the display panel than the reinforcement member S of the comparative embodiment.

[0076] Next, as shown in Table 2 below. Figure 4C and Figure 4D The maximum stress of the reinforcement S in the comparative embodiment and the maximum stress of the reinforcement 540 in the exemplary embodiment.

[0077] [Table 2]

[0078]

[0079]

[0080] refer to Figure 4C As a result of measuring the stress of the reinforcing member S in the comparative embodiment, it can be confirmed that the region A3 where the maximum stress is obtained is located in the central portion of the second reinforcing member S2. Furthermore, referring to Table 2, it can be confirmed that the maximum stress in the region A3 where the maximum stress is obtained in the reinforcing member S of the comparative embodiment is approximately 25.49 MPa.

[0081] Next, refer to Figure 4D As a result of measuring the stress of the reinforcing member 540 in the exemplary embodiment, it can be confirmed that the region A4 where the maximum stress is obtained is located in the protruding pattern E of the second reinforcing member 542. Furthermore, referring to Table 2, it can be confirmed that the maximum stress of the reinforcing member 540 in the region A4 where the maximum stress is obtained is approximately 29.40 MPa.

[0082] Therefore, it can be confirmed that the maximum stress generated in the reinforcing member 540 of the exemplary embodiment is greater than the maximum stress generated in the reinforcing member S of the comparative embodiment. At this time, Figure 4C and Figure 4D The stress referred to here is the stress applied to the reinforcement member during an impact applied to the display device. Therefore, this means that the reinforcement member 540 of the exemplary embodiment absorbs more impact than the reinforcement member S of the comparative embodiment. Thus, this means that when the same impact is applied to the reinforcement member S of the comparative embodiment and the reinforcement member 540 of the exemplary embodiment, the reinforcement member 540 of the exemplary embodiment absorbs more impact applied to the display panel than the reinforcement member S of the comparative embodiment.

[0083] Figures 5A to 5D This is a view used to explain the strain simulation results of the reinforcement of the display device according to an exemplary embodiment of the present disclosure. Figures 5A to 5D The results were obtained by measuring the strain of the reinforcing member S of the comparative embodiment and the reinforcing member 540 of the exemplary embodiment when a ball is dropped in the comparative embodiment and the exemplary embodiment. The reinforcing member 540 of the exemplary embodiment is the reinforcing member 540 of the display device 1000 according to the exemplary embodiment of the present disclosure. The only difference between the reinforcing member S of the comparative embodiment and the reinforcing member 540 of the display device 1000 according to the exemplary embodiment of the present disclosure is that the plurality of recessed patterns C are not provided in the plurality of first reinforcing members S1, and the plurality of protruding patterns E are not provided in the second reinforcing member S2. Figure 5A The simulation results were obtained by measuring the strain of the reinforcement S in the comparative embodiment when the ball landed on the center portion of the second reinforcement S2 in the comparative embodiment. Figure 5BThe simulation results were obtained by measuring the strain of the reinforcement 540 of the exemplary embodiment when the ball lands on the central portion of the second reinforcement 542 of the exemplary embodiment. Figure 5C The simulation results were obtained by measuring the strain of the reinforcement S of the comparative embodiment when the ball landed on the boundary portion of the plurality of first reinforcement S1 and second reinforcement S2 of the comparative embodiment. Figure 5D The simulation results were obtained by measuring the strain of the reinforcement 540 of the exemplary embodiment when a ball lands on the boundary portion of the plurality of first reinforcements 541 and second reinforcements 542. Figures 5A to 5D This means that the higher the density of points represented in a region, the higher the strain.

[0084] The following table 3 shows... Figure 5A and Figure 5B The maximum strain of the reinforcement S in the comparative embodiment and the maximum strain of the reinforcement 540 in the exemplary embodiment.

[0085] [Table 3]

[0086] Comparative Examples Exemplary embodiments Maximum strain 2.547e-03 1.570e-03

[0087] refer to Figure 5A As a result of measuring the strain of the reinforcing member S in the comparative embodiment, it can be confirmed that the region A5 where the maximum strain is obtained is located at the edge of the first reinforcing member S1. Furthermore, referring to Table 3, it can be confirmed that the maximum strain of the reinforcing member S in the comparative embodiment in the region A5 where the maximum strain is obtained is approximately 2.547e-03.

[0088] Next, refer to Figure 5B As a result of measuring the strain of the reinforcing member 540 in the exemplary embodiment, it can be confirmed that the region A6 where the maximum strain is obtained is located at the edge of the first reinforcing member 541. Furthermore, referring to Table 3, it can be confirmed that the maximum strain of the reinforcing member 540 in the region A6 where the maximum strain is obtained is approximately 1.570e-03.

[0089] Therefore, it can be confirmed that the strain in the reinforcement 540 of the exemplary embodiment is less than the strain in the reinforcement S of the comparative embodiment. This means that when the same impact is applied to the reinforcement S of the comparative embodiment and the reinforcement 540 of the exemplary embodiment, the reinforcement 540 of the exemplary embodiment is more effective at reducing the deformation of the display panel than the reinforcement S of the comparative embodiment.

[0090] Next, as shown in Table 4 below. Figures 5C to 5D The maximum strain of the reinforcement S in the comparative embodiment and the maximum strain of the reinforcement 540 in the exemplary embodiment.

Furthermore, referring to Table 4, it can be confirmed that the maximum strain of the reinforcing member S in the comparative embodiment in the region A7 where the maximum strain is obtained is approximately 1.245e-02.

[0095] Next, refer to Figure 5D As a result of measuring the strain of the reinforcing member 540 in the exemplary embodiment, it can be confirmed that the region A8 where the maximum strain is obtained is located in the protruding pattern E of the second reinforcing member 542. Furthermore, referring to Table 4, it can be confirmed that the maximum strain of the reinforcing member 540 in the region A8 where the maximum stress is obtained is approximately 7.598e-04.

[0096] Therefore, it can be confirmed that the strain in the reinforcement 540 of the exemplary embodiment is less than the strain in the reinforcement S of the comparative embodiment. This means that when the same impact is applied to the reinforcement S of the comparative embodiment and the reinforcement 540 of the exemplary embodiment, the reinforcement 540 of the exemplary embodiment is more effective at reducing the deformation of the display panel than the reinforcement S of the comparative embodiment.

[0097] The display panel of a display device includes multiple light-emitting diodes (LEDs) and multiple driving elements for driving the LEDs. However, when an impact is applied to the display device and the impact is concentrated on the display panel, it may cause black spots on the LEDs that are not emitting light. Therefore, in order to suppress black spots on the display device, a support layer supporting the display panel is provided on the rear surface of the display panel to absorb the impact applied to the display panel.

[0098] Therefore, in the display device 1000 according to an exemplary embodiment of the present disclosure, spaced-apart reinforcements 540 are provided on the support layer 500 provided on the rear surface of the display panel 400 to absorb impacts applied to the display panel 400. For example, if the rigid material supporting the display panel on the rear surface of the display panel is integrally formed, the impact applied to the display device may propagate to the entire surface of the rigid material supporting the rigid display panel. Therefore, in the display device 1000 according to an exemplary embodiment of the present disclosure, spaced-apart reinforcements 540 are provided on the support layer 500 to suppress the widespread propagation of impacts applied to the display device 1000. Therefore, when a collision due to a drop occurs in the display device 1000, the impact may not be transmitted between the spaced-apart reinforcements 540, allowing the display device 1000 to withstand the impact.

[0099] Furthermore, in the display device 1000 according to an exemplary embodiment of the present disclosure, adjacent first reinforcing members 541 and second reinforcing members 542 included in the reinforcing member 540 have an interconnection structure. Therefore, the bonding strength of the reinforcing member 540 can be enhanced, the damping rate of the reinforcing member 540 can be improved, and strain can be reduced. For example, the display device 1000 according to an exemplary embodiment of the present disclosure includes a second reinforcing member 542 and a plurality of first reinforcing members 541. The second reinforcing member 542 includes a plurality of protruding patterns E, the second reinforcing member 542 is disposed between the plurality of first reinforcing members 541, and the plurality of first reinforcing members 541 includes a plurality of recessed patterns C. In this case, the plurality of protruding patterns E of the second reinforcing member 542 are disposed in the plurality of recessed patterns C of the plurality of first reinforcing members 541, and the plurality of first reinforcing members 541 and second reinforcing members 542 can be joined to each other. Therefore, as the bonding strength of the plurality of first reinforcing members 541 and second reinforcing members 542 is enhanced, the stiffness of the reinforcing member 540 can also be enhanced. Therefore, the reinforcement 540 can easily absorb the impact applied to the display panel 400 and reduce the strain of the display panel 400.
