Description

Technical Field

[0001] This disclosure relates to a display device, and more specifically, to a display device having a structure that improves durability. Background Technology

[0002] The content described in this section is provided only as background information about this disclosure and does not constitute prior art.

[0003] As society enters the mature information age, the field of display devices that visually represent electrical information signals is developing rapidly, and research is underway to improve the performance of various types of display devices, such as reducing thickness, weight, and power consumption.

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

[0005] Display devices have been miniaturized to enhance user portability or installed in mobile devices such as vehicles, thereby improving user convenience.

[0006] In addition, display devices have been continuously improved to increase screen resolution and brightness, providing users with clearer images.

[0007] The descriptions provided in the Related Art section should not be considered prior art simply because they are mentioned or related to in that section. The discussion in the Related Art section may contain information describing one or more aspects of the subject matter art, and the descriptions in that section do not limit this disclosure. Summary of the Invention

[0008] Display devices can have a structure in which components made of different materials overlap each other. These components made of different materials can perform different functions within the display device.

[0009] For example, metal and plastic components can be arranged to overlap each other, and they can be securely connected by a coupling mechanism such as screws. However, when metal and plastic components are joined by a coupling mechanism, stress caused by thermal expansion becomes a problem.

[0010] When the display device is working, the electricity applied to the display device generates heat, which in turn heats the metal and plastic parts.

[0011] In this situation, thermal stress may be generated in the fixed metal and plastic components due to the difference in their coefficients of thermal expansion. This stress caused by the difference in coefficients of thermal expansion reduces the durability of the corresponding components.

[0012] In particular, plastic parts, which have relatively lower mechanical strength than metals, may undergo deformation or breakage due to accumulated stress.

[0013] Furthermore, the thermal expansion of plastic components can cause stress at the joint area where the plastic component adheres to another component. This is because the deformation of the plastic component due to stress causes stress to concentrate in a specific area of ​​the joint region located at the edge of the plastic component. Therefore, deformation caused by stress in the plastic component can lead to deformation or damage to the joint area.

[0014] Therefore, it is necessary to properly distribute the stress caused by the difference in the coefficients of thermal expansion of different materials in order to prevent or reduce stress concentration in specific areas, thereby suppressing deformation or damage to display device components.

[0015] Therefore, the object of this disclosure is to provide a display device having a structure capable of distributing stress caused by differences in the coefficients of thermal expansion between components made of different materials.

[0016] Another object of this disclosure is to provide a display device including a rib disposed between a core plate and a rear cover, the rib being configured to disperse stress arising from differences in the coefficients of thermal expansion.

[0017] The purposes of this disclosure are not limited to those described above, and other purposes and advantages not expressly stated will be understood from the following description and will become more apparent through implementation of this disclosure. Furthermore, it will be apparent that the purposes and advantages of this specification can be achieved by the means and combinations thereof set forth in the claims.

[0018] According to an embodiment, the display device may include a display panel displaying an image; a core plate disposed behind the display panel; a rear cover partially disposed behind the core plate and configured to receive the core plate; and a rib disposed between the core plate and the rear cover and configured to distribute stress generated between the core plate and the rear cover due to deformation differences between them.

[0019] The ribs can be configured to move in position in response to deformation of the core plate and the back cover, and to distribute stresses occurring in at least one of the core plate and the back cover.

[0020] According to another embodiment, a display device may include: a cover window; a display panel disposed behind the cover window and configured to display an image; a core board disposed behind the display panel; a rear cover, a portion of which is disposed behind the core board and configured to receive the core board; and

[0021] A rib is disposed between the core plate and the rear cover and is configured to distribute stress generated between the core plate and the rear cover due to deformation differences between them.

[0022] The rib may include a first segment protruding from the core plate and having a first concave-convex portion formed at its end, and a second segment protruding from the rear cover and having a second concave-convex portion formed at its end, the second concave-convex portion having a shape corresponding to and engaging with the first concave-convex portion.

[0023] In the display device disclosed herein, stress concentration can be suppressed in specific narrow areas within the region where the core plate and the back cover are joined by ribs.

[0024] Therefore, it can prevent or reduce stress concentration in a part of their connection area or in a specific direction when the core plate and back cover heat up, but can instead distribute it across the entire rib as the connection part of the two components, and the stress can also act simultaneously in the cross directions.

[0025] Therefore, it is possible to effectively suppress the stress that concentrates in a specific direction in the narrow area of ​​the core plate and back cover due to heat, thereby effectively preventing or reducing the severe deformation or damage of the back cover made of relatively weak plastic material due to stress concentration.

[0026] Furthermore, in the display device according to this disclosure, since the excessive deformation of the back cover caused by stress is suppressed by the ribs, stress concentration at a specific part of the adhesive portion located at the edge of the back cover can also be suppressed.

[0027] Therefore, it can prevent or reduce deformation or damage to the adhesive parts caused by stress concentration, and can effectively suppress damage to the cover window.

[0028] Furthermore, in the display device according to this disclosure, when the core board and the back cover heat up, their thermal expansion can become more significant at the corners. In particular, since the back cover can have a thin bend at the corners, the thermal expansion in that area can become even more significant.

[0029] Therefore, by placing ribs at the corners of the core plate and the back cover, stress concentration can be suppressed and stress can be effectively dispersed.

[0030] In addition to the effects described above, other beneficial effects of this disclosure will be provided together with the detailed description of this disclosure.

[0031] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory, and are intended to provide further explanation of the claimed inventive concept. Attached Figure Description

[0061] Reference Figure 2 In this instruction manual, "front" refers to the direction from the rear cover to the cover window, while the opposite direction is referred to as "rear".

[0062] The display device according to the embodiment may be, for example, a vehicle display device installed in front of the driver's seat in a vehicle.

[0063] The display device of the embodiment may include a display panel 100, a core board 200, and a back cover 300.

[0064] The display panel 100 can display images. In the vehicle display device, the displayed images may include navigation information required for driving, video captured by cameras installed in the vehicle, or various other content required by the driver or passengers.

[0065] The core board 200 can be disposed behind the display panel 100. The core board 200 can fix the display device of the embodiment to another object, such as a carrier. The core board 200 can generally be formed into a plate shape with a predetermined thickness and can be made of a metal material.

[0066] For example, core board 200 can be formed from magnesium and can be manufactured by a die-casting process.

[0067] The rear cover 300 may be partially disposed behind the core board 200 and may accommodate the core board 200. The rear cover 300 may be attached to the cover window 630 to form the appearance of the display device and may be adhered to the cover window 630 by means of the adhesive member 660.

[0068] The end of the back cover 300 can be partially bent to form a space for accommodating the core panel 200. For example, the back cover 300 can be made of plastic material and can be manufactured by injection molding.

[0069] In other words, the cover window 630 and the rear cover 300 can be connected to each other to form an interior space, and the core panel 200 and other components can be accommodated in the interior space.

[0070] The display device of the embodiment may include a polarizing plate 610, an adhesive layer 620, a cover window 630, a back plate 640, a metal plate 650, and an adhesive member 660.

[0071] A polarizing plate 610 can be positioned in front of the display panel 100. The polarizing plate 610 can convert light emitted from the display panel 100 into circularly polarized light. The polarizing plate 610 can improve the outdoor visibility and contrast of the image displayed on the display panel 100 by preventing or reducing the reflection of external light.

[0072] The adhesive layer 620 can be disposed in front of the polarizer 610 and can bond the cover window 630 and the polarizer 610 to each other. The adhesive layer 620 can be made of a transparent material. For example, the adhesive layer 620 can be a transparent optically transparent adhesive (OCA) with a relatively low modulus.

[0073] The cover window 630 can be positioned in front of the adhesive layer 620. The cover window 630 can be adhered to the back cover 300 to form the appearance of the display device and to protect other components of the display device.

[0074] The cover window 630 can be positioned at the very front of the display device. The cover window 630 can be positioned in front of the display panel 100 to protect the display panel 100. The cover window 630 can be formed of a transparent material, allowing light emitted from the display panel 100 to pass through the cover window 630.

[0075] The backplate 640 can be disposed behind the display panel 100 and can support the display panel 100. The backplate 640 may include a light source for illuminating the display panel 100.

[0076] The metal plate 650 can be disposed behind the back plate 640 and in front of the core plate 200. The metal plate 650 can be formed into a thin shape for manufacturing an ultra-thin display device.

[0077] The metal plate 650 can protect the display panel 100 and the back plate 640, and can also be used as a heat sink to cool the display panel 100 and the back plate 640 by dissipating the heat generated from the display panel 100 and the back plate 640 to the outside.

[0078] The metal sheet 650 can be made of, for example, aluminum or an alloy that includes aluminum.

[0079] An adhesive member 660 may be disposed between the cover window 630 and the rear cover 300. The adhesive member 660 can join the edges of the cover window 630 and the rear cover 300 together.

[0080] The adhesive member 660 may have an overall U-shape and may be adhered to the bent portion at the edge of the back cover 300. The cover window 630 and the back cover 300 may be joined together at their edges via the adhesive member 660.

[0081] Figure 4 This is a top cross-sectional view illustrating a display device according to an embodiment.

[0082] The core board 200, which serves as the structure for mounting the display device to the carrier, needs to be stably integrated with the other components of the display device. Because of this structure, the display device mounted to the carrier via the core board 200 can maintain its position even when subjected to external impacts and can provide the user with a stable image without shaking.

[0083] For this purpose, the core plate 200 can be fixedly connected to the rear cover 300. For example, the core plate 200 and the rear cover 300 can be connected by a connecting mechanism such as screws. However, in this case, the stress caused by the thermal expansion of the various components may become a problem.

[0084] When the display device is in operation, the electricity applied to the display device generates heat, and accordingly, the core board 200 made of metal material and the back cover 300 made of plastic material can become hot.

[0085] In this situation, due to the difference in the coefficients of thermal expansion between the metal and the plastic, stress caused by thermal expansion may be generated in the core plate 200 and the back cover 300, which are fixed to each other. The stress applied to the core plate 200 and the back cover 300 due to the difference in the coefficients of thermal expansion will reduce the durability of the individual components.

[0086] Specifically, the back cover 300, made of plastic with lower mechanical strength than metal, will experience deformation or breakage due to the accumulation of this stress.

[0087] Furthermore, the thermal expansion of the back cover 300 will generate stress in the adhesive member 660 that bonds the back cover 300 to the cover window 630. This is because deformation of the back cover 300 due to stress may cause stress to concentrate on specific portions of the adhesive member 660 located at the edges of the back cover 300. Therefore, deformation of the back cover 300 due to stress may cause deformation or breakage of the adhesive member 660.

[0088] Furthermore, concentrated stress on the adhesive member 660 may cause damage to the cover window 630 to which the adhesive member 660 is attached.

[0089] Therefore, it is necessary to properly distribute the stress caused by the difference in the coefficients of thermal expansion of different materials in order to prevent or reduce stress concentration in specific areas, thereby suppressing deformation or damage to display device components.

[0090] In this embodiment, the aforementioned problem can be solved by connecting the rear cover 300 to the core plate 200 and providing a rib 400 between the rear cover 300 and the core plate 200 to distribute the stress applied thereto. The rib 400 will now be described in detail with reference to the accompanying drawings.

[0091] Figure 5 yes Figure 4 A magnified view of a portion of it. Figure 6 This is a perspective view of the rib 400 illustrating an embodiment. The display device of this embodiment may include the rib 400.

[0092] Rib 400 can be disposed between core plate 200 and back cover 300, and can disperse the stress generated in core plate 200 and back cover 300 due to the deformation difference between core plate 200 and back cover 300.

[0093] The rib 400 can distribute the stress generated in the core plate 200 and the back cover 300, which is caused by the deformation difference caused by the material difference between the core plate 200 and the back cover 300 when the display device is working and heating.

[0094] The rib 400 can move in position according to the deformation of the core plate 200 and the rear cover 300, thereby distributing the stress generated in at least one of the core plate 200 or the rear cover 300.

[0095] Rib 400 may include a first segment 410 and a second segment 420. The first segment 410 may protrude from the core plate 200 and has a first protrusion 411 formed at its end. The second segment 420 may protrude from the rear cover 300 and has a second protrusion 421 formed at its end, the shape of the second protrusion 421 corresponding to and interlocking with the first protrusion 411.

[0096] The first and second convex portions 411 and 421 may include a recess 4001 having at least one inclined surface 4002. The first and second convex portions 411 and 421 may be generally formed in a serrated shape and may interlock with each other.

[0097] The first segment 410 and the second segment 420 can be connected to each other through the interlocking engagement between the first protrusion / contour portion 411 and the second protrusion / contour portion 421, thereby connecting the core plate 200 and the rear cover 300 together. Of course, as will be described later, the core plate 200 and the rear cover 300 can also be connected by a connecting mechanism.

[0098] Since the first and second convex portions 411 and 421 are arranged in corresponding sawtooth shapes, the first segment 410 and the second segment 420 can easily interlock with each other during the assembly of the connecting core plate 200 and the back cover 300, which can facilitate the assembly of the display device.

[0099] Now refer to Figure 6 The following description is provided. Due to the difference in their coefficients of thermal expansion, stress can be applied to the first segment 410 of the rib 400 in direction ① and to the second segment 420 in direction ②. This is because the core plate 200, made of metal, and the back cover 300, made of plastic, have different coefficients of thermal expansion, resulting in different elongations, which may lead to stress in opposite directions.

[0100] Of course, stress can also be generated in the core plate 200 and the back cover 300 in the same direction as the stress applied to the first segment 410 and the second segment 420.

[0101] In this case, the first uneven portion 411 of the first segment 410 and the second uneven portion 421 of the second segment 420 can be formed with an inclined surface 4002, and due to the inclined surface 4002, a portion of the stress applied to the first segment 410 and the second segment 420 can be applied in directions ③ and ④ that intersect with directions ① and ②.

[0102] In other words, a portion of the stress in the first segment 410 and the second segment 420 can be distributed in directions ③ and ④. Therefore, the stress can be distributed along the intersecting directions within the first segment 410 and the second segment 420.

[0103] Due to this structure, compared to the case where stress is applied only in directions ① and ②, stress concentration in specific areas and directions of the core plate 200 and the back cover 300 can be suppressed.

[0104] That is, in the area where the ribs 400 for connecting the core plate 200 and the back cover 300 are formed, stress concentration in a narrower specific part can also be suppressed.

[0105] Therefore, when the core plate 200 and the back cover 300 are heated, stress concentration in specific directions and areas of their connection area can be prevented or reduced, and stress can be distributed across the entire rib 400 that serves as the connection part, while acting in the intersecting direction.

[0106] As a result, stress concentration in a narrow, specific area of ​​the core plate 200 and the back cover 300 in a specific direction due to heating can be effectively suppressed, and thus severe deformation or damage to the relatively weak back cover 300 due to its plastic form can be effectively prevented or reduced.

[0107] In addition, since the rib 400 suppresses excessive deformation of the back cover 300 caused by stress, stress concentration in a specific area of ​​the adhesive member 660 at the edge of the back cover 300 can also be suppressed.

[0108] Therefore, deformation or damage to the adhesive member 660 caused by stress concentration can be prevented or reduced, and damage to the cover window 630 can be effectively suppressed.

[0109] The first segment 410 can be integrally formed with the core board 200, and the second segment 420 can be integrally formed with the back cover 300.

[0110] When the core board 200 and the first segment 410 are manufactured separately and then assembled together, there is a risk of separation or damage at the joint due to repeated thermal expansion. Therefore, the core board 200 and the first segment 410 can be integrally formed to improve the durability of the display device.

[0111] For the same reason, it is also appropriate to form the back cover 300 and the second segment 420 as a single unit.

[0112] The core plate 200 and the first component 410, made of metal, can be integrally formed, for example, by die casting. The back cover 300 and the second component 420, made of plastic, can be integrally formed by injection molding.

[0113] Figure 7 This is a perspective view illustrating a first segment 410 or a second segment 420 according to an embodiment. In the embodiment, the recess 4001 of the first segment 410 or the second segment 420 may be formed as an asymmetrical shape having two surfaces with different tilt angles.

[0114] like Figure 7 As shown, for example, one surface of the recess 4001 can be formed as an inclined surface 4002 with a slope, and the other surface of the recess 4001 can be formed as a surface that is generally perpendicular to directions ① and ②, such that the two surfaces of the recess 4001 can have different slopes.

[0115] Figure 8 This is a perspective view illustrating a first segment 410 or a second segment 420 according to another embodiment. In another embodiment, the recess 4001 of the first segment 410 or the second segment 420 may be formed in a symmetrical shape having two inclined surfaces 4002 with the same tilt angle.

[0116] Even when the inclined surface 4002 is formed only on one side of the recess 4001, the stress can be distributed in directions ③ and ④, and thus one side of the recess 4001 is formed as a right-angled surface, while the other side is formed as an inclined surface 4002.

[0117] The formation of the recess 4001 can be designed to reflect the size, specific structure, and thermal deformation characteristics of the display device. That is, the rib 400 can be designed by appropriately adjusting the number and size of the recesses 4001 of the first segment 410 and the second segment 420, as well as the angle of the inclined surface 4002, while taking into account the size, structure, and thermal deformation characteristics corresponding to the materials of the various components of the display device.

[0118] Figure 9 This is a perspective view of the display device with the back cover 300 omitted. Figure 10 yes Figure 9 A magnified view of a portion of it. Figure 11 This is a front view illustrating the rear cover 300 according to an embodiment. Figure 12 This is an enlarged view of a portion of the back cover 300 according to the embodiment.

[0119] Rib 400 can be positioned at the edge 1201 of core plate 200 and the corresponding edge 1201 of back cover 300.

[0120] When the core plate 200 and the back cover 300 heat up, their thermal expansion can become more significant at the edge 1201. In particular, the back cover 300 may have a thin bending section at the edge 1201, making thermal expansion more significant in that area.

[0121] Therefore, by providing ribs 400 at the edges 1201 of the core plate 200 and the back cover 300, stress concentration can be suppressed and stress can be effectively dispersed.

[0122] In one embodiment, the core board 200 may include a first planar portion 210 and side portions 220 defined by both sides of the first planar portion 210. A first segment 410 may be positioned on both the first planar portion 210 and the side portions 220.

[0123] At least one first segment 410 may be positioned on the first planar portion 210 and the side portion 220. For a wider stress distribution, it is preferable to have a plurality of first segments 410 disposed on both the first planar portion 210 and the side portion 220.

[0124] Furthermore, the second segment 420 of the back cover 300 can be provided in the same number as the first segment 410 of the core board 200.

[0125] The back cover 300 may include a second planar portion 310 and a bent portion 320 bent from the second planar portion 310. A second segment 420 may be positioned on both the second planar portion 310 and the bent portion 320. The position and number of the second segments 420 disposed on the second planar portion 310 and the bent portion 320 may correspond to the position and number of the first segments 410.

[0126] In other words, the ribs 400 can be respectively set on different surfaces of the core plate 200 and the back cover 300. With this structure, stress can be widely distributed at the edges 1201 of the core plate 200 and the back cover 300.

[0127] The number of ribs 400 provided on the various surfaces of the edge 1201 of the core plate 200 and the back cover 300 can be appropriately set taking into account factors such as the size, structure and thermal deformation characteristics of the various components of the display device.

[0128] In addition to the rib 400, the core plate 200 and the back cover 300 can also be connected by a connecting mechanism such as screws to maintain a stable connection.

[0129] However, when the core plate 200 and the back cover 300 are fixedly connected by the connecting mechanism, stress will be generated at the connection point due to the difference in thermal expansion rates between the materials of the core plate 200 and the back cover 300.

[0130] Therefore, the connection points of the connecting mechanism need to be positioned so that the stress caused by heat in the core plate 200 and the rear cover 300 will not cause deformation of these components. Taking these factors into consideration, the position where the core plate 200 and the rear cover 300 are fixedly connected by the connecting mechanism in the embodiment is described below.

[0131] The core plate 200 may include a plurality of first fastening holes 230 spaced apart on the first planar portion 210 for fixing the connection mechanism.

[0132] like Figure 9 As shown, a plurality of first fastening holes 230 can be provided on the first planar portion 210 of the core plate 200 in a direction parallel to the lateral direction of the display device.

[0133] Accordingly, the rear cover 300 may include a plurality of second fastening holes 330, each of which is formed on the second planar portion 310 at a position corresponding to the first fastening hole 230, to secure the connecting mechanism.

[0134] like Figure 11 As shown, a plurality of second fastening holes 330 can be provided on the second planar portion 310 of the rear cover 300 in a direction parallel to the lateral direction of the display device. The second fastening holes 330 can be formed at positions corresponding to the first fastening holes 230 of the core plate 200, and the number of second fastening holes 330 corresponds to the number of first fastening holes 230.

[0135] As previously mentioned, the stress caused by thermal expansion in the core plate 200 and the rear cover 300 is particularly significant at the edge 1201. Therefore, the edges 1201 of the core plate 200 and the rear cover 300 can be connected using ribs 400, thereby effectively suppressing stress-induced deformation and damage.

[0136] Additionally, fastening holes can be formed in the planar portions of the core plate 200 and the rear cover 300, where stress generation is relatively insignificant, allowing the core plate 200 and the rear cover 300 to be joined together using a connecting mechanism.

[0137] By using a connecting mechanism at a location where stress is not significant, the core plate 200 and the rear cover 300 can be connected in a stable and secure manner without deformation or damage due to stress.

[0138] Reference Figure 9 and Figure 10 The first fastening hole 230 and the second fastening hole 330 may not be formed on the side portion 220 of the core plate 200 and the bent portion 320 of the rear cover 300, but are formed on a planar portion that is spaced at a predetermined distance from the side portion 220 and the bent portion 320.

[0139] This structure helps to reduce the magnitude of stress caused by the connecting mechanism on the side portion 220 and the bent portion 320, where the stress caused by thermal expansion is significant, thereby significantly reducing the deformation and damage of the core plate 200 and the back cover 300 caused by stress.

[0140] The first segment 410 and the second segment 420 can be disposed on one side of the core plate 200 and the rear cover 300. On the other hand, the first fastening hole 230 and the second fastening hole 330 can be disposed on opposite sides of the core plate 200 and the rear cover 300, respectively.

[0141] Reference Figure 9 and Figure 10 When the display device is installed in a carrier, the ribs 400 are provided at the upper corners (e.g., edges 1201) on both sides of the display device, and the connecting mechanism for fixing and fastening holes can be provided on the lower flat portion of the display device.

[0142] Therefore, the rib 400 and the connecting mechanism can be positioned significantly separated in the vertical direction of the display device. Consequently, the stress generated at the fastening mechanism has little or no effect on the rib 400.

[0143] Therefore, the stress generated by the fastening mechanism will not impact the upper corners of the display device, thus effectively preventing or reducing deformation and damage to the back cover 300 due to stress at these corners.
