Description

TECHNICAL FIELD

[0001] The disclosure relates to a display apparatus, and more particularly, to a display apparatus in which a display panel is bendable. BACKGROUND

[0002] Recently, as we enter the information age, the field of displays that visually present electrical information signals is rapidly developing. In response to this trend, various display apparatuses are being developed.

[0003] Specific examples of these display apparatuses include liquid crystal display apparatuses (LCDs), organic light emitting display apparatuses (OLEDs), and quantum dot display apparatuses.

[0004] However, these display apparatuses have known defects and limitations. For example, although it can generally be desirable to increase the viewable area of the screen of these types of display apparatuses, increasing the viewable area reduces the bezel area around the screen for connections between various components of the display apparatus, and can cause weaker connections to be more prone to failure. These problems are particularly evident for recently developed foldable and bendable displays. In addition, certain parts of known display apparatuses are manually assembled, and as the size of the workspace or bezel area on the apparatus decreases to increase the viewable area of the screen, this increases the likelihood of assembly errors. SUMMARY

[0005] The display apparatus of the disclosure can be a display apparatus having thinness, light weight, low power consumption, and excellent performance.

[0006] In an embodiment, since an organic light emitting display apparatus does not require a separate light source, a compact apparatus is realized and clear color display is realized, a self-emissive display apparatus such as an organic light emitting display apparatus is considered to be a competitive application. An organic light emitting display apparatus has a self-emissive element in each pixel, which means that there is no separate light source. The light emitting element has two electrodes facing each other and a light emitting layer disposed between the two electrodes, thereby emitting light when the transported electrons and holes recombine with each other therein. The organic light emitting element is a self-emissive element using a thin light emitting layer between the electrodes, and has the advantage that thinness can be achieved. In addition, the organic light emitting display apparatus does not require a separate light source apparatus, and thus has flexibility, bendability, or foldability, thereby realizing a foldable display apparatus that can be designed in various forms.

[0007] Recently, users prefer a narrow or bezel-less design in which the entire area is a display area when a user views a screen. The inventors have found that an edge area of the display area includes a connection that combines or mounts the display panel or the display device to the module. For example, a decorative plate and a back cover can be fixed to a side surface of the package glass or the display panel in the edge area by a screw or a tape. The edge area can be a bezel in an elevation view of the display device. In order to allow such a space for the connection, the size of the bezel that fixes the display panel can be increased. In order to implement the bezel-less design preferred by the user, the inventors have noted that a space of a connection point between the display panel or the display device and the module can be reduced or minimized. Specifically, the inventors have proposed that, in order to minimize the bezel area, a structure of a core plate that supports a rear surface of the display panel and a structure of a back cover disposed on a rear surface of the core plate to cover a rear surface of the display device can be different from each other so that the space at the connection point between the display device and the module can be reduced or minimized.

[0008] In addition, the inventors have also noted that, if a screw or a tape is used in a process of combining the core plate and the back cover to the display panel, efficient mass production can be reduced. The combining process using the screw or the tape can be manually performed by an operator, and defects can occur due to an error of the manual work. Therefore, a scheme that omits or minimizes the manual work that is desirable and advantageous with respect to the known display device can be considered.

[0009] A scheme that ensures robustness of the combination while the operator easily combines the core plate and the back cover to the display panel and a structure that enables the core plate and the back cover to be detached from the display panel after the combination in order to repair a problem, which are desirable and advantageous with respect to the known display device, can also be considered.

[0010] When the bezel-less design is used, the user can be more immersed in the screen, and the aesthetic appearance of the display device can be improved.

[0011] The concept of the present disclosure aims to overcome the above-described disadvantages of the known display device. In an embodiment of the present disclosure, the bezel size of the display device is reduced so that the user can be more immersed in the screen.

[0012] More specifically, the core plate supports a rear surface of the display panel or bends the display panel into a desired shape, and the display device is combined to the module. The back cover covers the rear surface of the core plate and functions to constitute the appearance of the rear surface of the display device. In this regard, the concept of the present disclosure improves the processability by improving the combination between the core plate and the back cover.

[0013] A solution to improve workability of an operator while ensuring robustness of the bonding of the core plate and the rear cover is also contemplated herein. When workability is improved while the bonding is poor, quality problems can occur. For example, a display device attached to a vehicle can be exposed to extremely cold or hot outdoor temperatures. Due to periodic or irregular vibrations occurring during driving of the vehicle, the bonding between the core plate and the rear cover and the display panel can become loose or even fail. Accordingly, the inventive concept realizes a robust bonding between the core plate and the rear cover.

[0014] In an embodiment of the disclosure, a design of a core plate and a rear cover stably realizing a bezel-less structure of a display device is provided.

[0015] In one or more embodiments of the disclosure, a display device includes a display panel; a decorative film and an encapsulation glass disposed on a front surface of the display panel; a core plate supporting a rear surface of the display panel and attached to the rear surface of the display panel; and a rear cover bonded with a rear surface of the core plate, wherein the core plate has a protrusion protruding toward the encapsulation glass, wherein the rear cover has a bonding portion bonded with the protrusion to cover at least a portion of the protrusion, wherein a resin is applied to at least a portion of the bonding portion, and the rear cover is adhered to the decorative film or the encapsulation glass by the resin.

[0016] In one or more embodiments of the disclosure, a display device includes a display panel including a flexible substrate; a decorative film and an encapsulation glass disposed on a front surface of the display panel; a core plate supporting a rear surface of the display panel and attached to the rear surface of the display panel; and a rear cover bonded with a rear surface of the core plate, wherein the core plate has an edge region divided into a first region, a second region, and a third region, wherein the core plate has a protrusion protruding toward the encapsulation glass, wherein the protrusion is disposed in the edge region, wherein a resin is applied to at least a portion of the protrusion, and the rear cover is adhered to the decorative film or the encapsulation glass by the resin.

[0017] According to embodiments of the disclosure, a display device having a bezel-less form can be provided by a bonding structure of a display panel, a core plate, and a rear cover constituting the display device. Changing the bonding structure between the core plate and the rear cover can minimize a side portion space of the display panel, so that a bezel area can be narrowed, while allowing strong and reliable bonding between various solutions of the display device to improve performance and reliability.

[0018] Accordingly, it is aesthetically pleasing for a user of the display device to view a light emitting screen occupying a large portion of a front surface of the display device. Due to the narrow bezel, a compact display device can be realized. In other applications, this can be more advantageous for interior design of a vehicle.

[0019] The display apparatus according to embodiments of the disclosure can be simplified by changing the coupling structure of the display panel, the core plate, and the back cover. This means that the work of an assembly worker is simplified, and since the process is simplified, an effect of improved productivity can be expected. For example, in a conventional work scheme, structures such as the core plate, the back cover, and the decorative plate are coupled to each other using side screws or a tape. According to the disclosure, improving the coupling structure can allow the core plate and the back cover to be coupled to each other without a separate fastening device.

[0020] Advantages of the concept of the disclosure are not limited to the above-described advantages. Other advantages and effects of the disclosure not mentioned can be understood based on the following description, and can be more clearly understood based on embodiments of the disclosure. Furthermore, it will be readily understood that the advantages and effects of the disclosure can be achieved using the concept of the disclosure and combinations thereof. Specific details of other embodiments are described with reference to the detailed description and the accompanying drawings.

[0021] The advantages and effects as described above do not specifically describe the essential characteristics of the claims, and thus do not limit the scope of the disclosure. BRIEF DESCRIPTION OF DRAWINGS

In addition, the display panel used in the display device according to the embodiments of the present disclosure is not limited to the shape or size of the display panel.

[0053] More specifically, when the display panel is implemented as an organic light emitting diode (OLED) display panel, the display panel can include a plurality of gate lines, a plurality of data lines, and pixels respectively formed in regions where the gate lines and the data lines cross each other. Further, the display panel can be configured to include an array including thin film transistors as elements for selectively applying a voltage to each pixel, an organic light emitting element layer on the array, and an encapsulation substrate or an encapsulation layer disposed on the array to cover the organic light emitting element layer. The encapsulation layer protects the thin film transistors and the organic light emitting element layer from external impact, and can prevent moisture or oxygen from permeating into the organic light emitting element layer. Further, a light emitting layer formed on the array can include an inorganic light emitting layer, such as a nano-scale material layer or a quantum dot.

[0054] FIG. 1A and FIG. 1B Embodiments of an organic light emitting diode display panel 100 that can be incorporated into the display apparatus 10 are illustrated.

[0055] FIG. 1A and FIG. 1B are plan views respectively illustrating a front surface 10A and a rear surface 10B of the display apparatus 10 according to an embodiment of the disclosure. FIG. 1A illustrates the front surface 10A of the display panel 100, FIG. 1B illustrates the rear surface 10B thereof, exposing a core plate 200 and a rear cover 300 of the display panel 100. As FIG. 1B illustrated, the core plate 200 can have a first connector 201 and a second connector 202 for connecting the core plate 200 to a coupling portion of a vehicle, thereby attaching and fixing the display apparatus 10 to the vehicle. Each of the first connector 201 and the second connector 202 can have a bolt hole to accommodate a bolt for coupling the display apparatus 10 to the vehicle. However, the shape or number of the connectors is not limited thereto. The display apparatus 10 or the display panel 100 can generally have a rectangular or square shape. However, the disclosure is not limited thereto. As FIG. 1A and 1B illustrated, the display apparatus 10 or the display panel 100 can include a shape having an acute angle profile, an obtuse angle profile, or a curved profile.

[0056] In particular, as referred to in the following at least FIG. 2In more detail, the front surface 10A can be an outward-facing surface of the device 10 for displaying information to a user through the display panel 100. The rear surface 10B is a back surface of the display device 10 for mounting the device 10 to a support structure, for example, integrating the display device 10 to a vehicle and incorporating the display device 10 to the vehicle. Accordingly, in one embodiment, the display panel 100 of the display device 10 can correspond to a dashboard or other electronic display of the vehicle, the front surface 10A is visible to a user sitting in the vehicle and the display panel 100 displays certain information to the user on the front surface 10A of the display device. Referring to FIG. 1B On the rear surface of the display device 10, the core plate 200 can be mainly connected to the incorporation portion of the vehicle, and the rear cover 300 can be exposed.

[0057] FIG. 2 is a cross-sectional view of the display panel 100 of the display device 10 along line I-I' in FIG. 1. The display panel 100 can include a substrate 111 supporting various components of the display panel 100. The substrate 111 can be made of a transparent insulating material, for example, an insulating material such as glass or plastic. When the substrate 111 is made of plastic, the substrate can be implemented as a plastic film or a plastic substrate. For example, the substrate 111 can be in the form of a film including one of a polyimide-based polymer, a polyether-based polymer, a silicon-based polymer, an acrylic polymer, a polyolefin-based polymer, and a copolymer thereof. Polyimide can be applied to a high-temperature process and can be coated, and thus can be used for a plastic substrate.

[0058] In one embodiment, a buffer layer 113 can be located on the substrate 111 and directly on the substrate 111. The buffer layer 113 can protect a thin film transistor (TFT) from impurities such as alkali ions from the substrate 111. The buffer layer 113 can be made of silicon oxide (SiOx) or silicon nitride (SiNx), or can be composed of a plurality of layers made thereof. However, the present disclosure is not limited thereto, and the buffer layer 113 can be omitted in some embodiments.

[0059] A thin film transistor 130 can be disposed on the buffer layer. A gate 132, a gate insulating layer 112, a semiconductor layer 134, an interlayer insulating layer 114, a source 136, and a drain 138 are sequentially stacked to form the thin film transistor 130. At least one thin film transistor 130 can be disposed in a plurality of sub-pixels disposed in an active area.

[0060] Although FIG. 2 The thin film transistor 130 shown in FIG. 1 is of a bottom gate type, but the present disclosure is not limited thereto. A top gate type in which the arrangement order of the semiconductor layer 134 and the gate 132 is reversed can also be applied.

[0061] The semiconductor layer 134 can be disposed on a specific portion of the substrate 111 or the buffer layer 113. The semiconductor layer 134 can be made of polysilicon (p-Si). In this case, a portion of the semiconductor layer 134 serving as an electrode layer can be doped with an impurity. Also, the semiconductor layer 134 can be made of amorphous silicon (a-Si), or can be made of various organic semiconductor materials such as pentacene. In another example, the semiconductor layer 134 can be made of an oxide. The gate insulating layer 112 can be made of an inorganic insulating material such as silicon oxide (SiOx) or silicon nitride (SiNx), or can also be made of an organic insulating material. The gate 132 can be made of various conductive materials, for example, magnesium (Mg), aluminum (Al), nickel (Ni), chromium (Cr), molybdenum (Mo), tungsten (W), gold (Au), or an alloy thereof. However, the present disclosure is not limited thereto.

[0062] The first interlayer insulating layer 114 can be made of an insulating material such as silicon oxide (SiOx) or silicon nitride (SiNx), or can also be made of an organic insulating material. A contact hole exposing the source and drain regions, respectively, can be formed by selectively removing a portion of the first interlayer insulating layer 114.

[0063] Each of the source 136 and the drain 138 can be formed on the first interlayer insulating layer 114, in a single layer or multiple layers, and can be made of an electrode material.

[0064] The inorganic protective layer 116 and the planarization layer 118 can be disposed on the thin film transistor to cover the source 136 and the drain 138. The inorganic protective layer 116 and the planarization layer 118 protect the thin film transistor and planarize a step due to the thin film transistor. The inorganic protective layer 116 can be composed of an inorganic insulating film such as a silicon nitride film (SiNx) or a silicon oxide film (SiOx). The planarization layer 118 can be composed of an organic insulating film made of, for example, BCB (benzocyclobutene) or acrylic acid. Each of the inorganic protective layer 116 and the planarization layer 118 can be formed as a single layer or can be composed of two or more layers. One of the inorganic protective layer 116 and the planarization layer 118 can be omitted.

[0065] The light emitting element 119 of the display panel 100 can have a form in which the first electrode 122, the organic light emitting layer 124, and the second electrode 126 are sequentially stacked on the thin film transistor 130. That is, the light emitting element 119 includes the first electrode 122 connected to the drain 138 through a connection hole extending through the planarization layer 118 and the inorganic protective layer 116, the organic light emitting layer 124 located on the first electrode 122, and the second electrode 126 located on the organic light emitting layer 114.

[0066] When the display panel 100 is a top emission type that emits light upward toward the second electrode 126, the first electrode 122 can include an opaque conductive material having high reflectivity. For example, the reflective conductive material can include silver (Ag), aluminum (Al), gold (Au), molybdenum (Mo), tungsten (W), chromium (Cr), or an alloy thereof. However, the present disclosure is not limited thereto.

[0067] The bank 128 exposes the light emitting area and is formed in the remaining area other than the light emitting area. Accordingly, a bank hole or an opening is defined in the bank 128, which exposes the first electrode 122 and corresponds to the light emitting area. The bank 128 can be made of an inorganic insulating material such as a silicon nitride film (SiNx) or a silicon oxide film (SiOx), or an organic insulating material such as BCB, an acrylic resin, or an imide resin.

[0068] The organic light emitting layer 124 is disposed on the first electrode 122 exposed through the bank hole or the opening in the bank 128. The organic light emitting layer 124 can include a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, and an electron injection layer. Further, the organic light emitting layer 124 can have a single stack structure of a single light emitting layer emitting monochromatic light, or a multi-stack structure including a plurality of stacks each having a single light emitting layer emitting monochromatic light. In this case, in order to display various colors, adjacent sub-pixels can emit different colors of light. For example, sub-pixels respectively having a red light emitting layer, a green light emitting layer, and a blue light emitting layer can be disposed side by side or spaced apart from each other, while sub-pixels of a specific color are disposed in parallel to each other, and other sub-pixels are disposed diagonally to form a triangular structure or a Pentile structure.

[0069] In another example, a white sub-pixel can be added. In another example of the arrangement of the organic light emitting layer 124, a plurality of stacks including light emitting layers emitting different colors of light are stacked to represent white. When white is represented from the stack structure, a separate color filter can be added to each pixel.

[0070] The second electrode 126 is disposed on the organic light emitting layer 124. When the display panel 100 operates in a top emission scheme, the second electrode 126 can be made of a transparent conductive material such as indium tin oxide (ITO) or indium zinc oxide (IZO), or can be made of a semi-transmissive metal or a metal alloy such as MgAg. Accordingly, light generated from the organic light emitting layer 124 can be emitted upward toward the second electrode 126.

[0071] A cover layer can be disposed on the second electrode 126. The cover layer can protect the light emitting element 119, and can be made of a material having an appropriate refractive index to help extract light emitted from the second electrode 126.

[0072] A packaging layer 140 can be disposed on the light emitting element 119. The packaging layer 140 prevents oxygen and moisture from the outside from penetrating into the light emitting material and the electrode material, to prevent oxidation of the light emitting material and the electrode material. When the light emitting element 119 is exposed to moisture or oxygen, a pixel shrink phenomenon in which the light emitting area is reduced, or a dark spot can occur in the light emitting area. The packaging layer 140 can have a structure in which a first inorganic layer 142 and a second inorganic layer 146 made of a glass, metal, aluminum oxide (AlO x ) or silicon (Si)-based material, and an organic layer 144 improving planarization performance and reducing stress between layers due to bending of the display panel 100, are alternately stacked. The composition of the organic layer 144 can include an organic insulating material such as an acrylic resin, an epoxy resin, a polyimide, a polyethylene, or a silicon-oxygen-carbon (SiOC). The first inorganic layer 142 and the second inorganic layer 146 function to block penetration of moisture or oxygen, and the organic layer 144 functions to planarize the surface of the first inorganic layer 142. When the packaging layer 140 is formed as a multi-layer thin film layer, the path traveled by moisture or oxygen becomes longer and more complex compared to the case where the packaging layer 140 is formed as a single layer, making it difficult for moisture / oxygen to intrude into the light emitting element.

[0073] A protective layer can be further formed between the light emitting element 119 and the packaging layer 140 to protect the packaging layer 140, so that the side surface of the packaging layer 140 is not peeled off or its uniformity is not affected in the manufacturing process of the packaging layer 140.

[0074] Referring to FIG. 2 , a polarization layer 154 can be disposed on the packaging layer 140. The polarization layer 154 can minimize the effect of light from an external light source entering the panel 100 on the semiconductor layer 134 or the light emitting layer 124.

[0075] Referring to FIG. 2 , a touch sensor layer 155 can be disposed on the polarization layer 154. The touch sensor layer 155 can have a structure in which a first touch electrode 155a and a second touch electrode 155c are disposed to cross each other, and a voltage signal is applied to one of the touch electrodes, and the other touch electrode senses the voltage signal. Each of the first touch electrode 155a and the second touch electrode 155c can be disposed on a touch insulating layer 155b and can be patterned in a polygonal or circular shape such that the patterns are spaced apart from each other.

[0076] A cover member 180 can be disposed on the touch sensor layer 155. An adhesive can be further disposed between the touch sensor layer 155 and the cover member 180, so that the touch sensor layer 155 and the cover member 180 are combined with each other.

[0077] FIG. 3A andFIG. 3B are plan views of the core plate 200 and the back cover 300, respectively. Referring to FIG. 3A , the core plate 200 can be manufactured in a shape identical to that of the display panel 100. Thus, the core plate 200 can sufficiently reinforce and support the rear surface of the display panel 100. To this end, the core plate 200 can be made of a metal-based material having a rigidity greater than that of the display panel 100. For example, the core plate 200 can be manufactured through a die casting process by using magnesium (Mg), aluminum (Al), or the like, which has a relatively good workability. However, the material of the core plate 200 is not limited thereto. Another reason that the core plate 200 is made of a metal-based material is that metal can well dissipate heat that can be generated from the display panel 100. In other words, the core plate 200 can have a dual function of dissipating heat generated due to the operation of the display panel 100 as a heat sink while serving as a support for the display panel 100.

[0078] More specifically, a polyimide-based polymer or plastic used as a material for a substrate of the display panel 100 can have poor thermal conductivity, and thus can not dissipate heat from the driver of the display panel 100. This can adversely affect the light emitting element 119 FIG. 2 ). Thus, when the core plate 200 made of a metal material having excellent thermal conductivity is disposed at the rear surface of the display panel 100, heat of the display panel 100 can be dissipated through the core plate 200 to improve the reliability and performance of the display panel 100. The die casting process is a precision casting method that obtains a casting having the same shape as that of a mold by injecting molten metal into a mold made of a rigid material and already accurately shaped to match a target shape. A part produced through the die casting process has an accurate size, thus requiring little or no finishing, and also has excellent mechanical properties and is mass-produced. For this reason, the die casting process can be mainly used to produce precision parts, for example, automobile parts, electrical parts, and optical parts. Other forming techniques and processes of the core plate 200 are also contemplated herein. In addition, other heat dissipation techniques, for example, a separate heat sink and a heat spreader, are contemplated herein to replace or be added to the core plate 200.

[0079] Referring to FIG. 3B , the back cover 300 can be disposed to cover at least a portion of the rear surface of the core plate 200 of FIG. 3A . Referring to FIG. 4The assembly of the display panel 100, the core plate 200, and the back cover 300 is described and illustrated in more detail. The back cover 300 can have a different shape from the display panel 100 and can serve as an appearance of a rear surface of the display device 10 or can function to protect certain components of the display device 10. In consideration of the direct coupling of the core plate 200 to a vehicle, the area of the core plate 200 on which the display device 10 is mounted on a vehicle or other support can be empty without the back cover 300. For example, the upper portion of the back cover 300 has the same profile as that of the display panel 100 or the core plate 200, while the lower portion of the back cover 300 can be an empty space because a connector for coupling the core plate 200 to a vehicle or assembly is disposed in the area of the core plate corresponding to the empty space of the back cover. Accordingly, the back cover 300 can be disposed on a portion of the core plate 200 that does not include a connector and other similar structures for coupling the core plate 200 to a vehicle or other support. The back cover 300 can be made of a thermoplastic plastic. For example, the back cover 300 can be made of polyethylene, polypropylene, polystyrene, polycarbonate, or ABS (acrylonitrile, butadiene, and styrene) and can be manufactured using plastic injection molding. In an embodiment in which the back cover 300 is ABS (acrylonitrile, butadiene, and styrene), among the three materials, styrene can be the main raw material.

[0080] Injection molding is a representative processing method for molding thermoplastic resins and has the advantage of being able to mold products from small to large sizes and enable mass production through repeated injection molding. However, other processing methods and techniques are also considered herein.

[0081] FIG. 4 is an exploded perspective view of the display device 10. In FIG. 4 is sequentially illustrated that the display device 10 includes a display panel 100, a core plate 200 supporting the display panel 100, and a back cover 300 disposed on the core plate 200. In more detail, the display panel 100 has a front surface 100A and a rear surface 100B opposite the front surface 100A, the core plate 200 has a front surface 200A and a rear surface 200B opposite the front surface 200A, and the back cover 300 has a front surface 300A and a rear surface 300B opposite the front surface 300A. The front surface 200A of the core plate 200 is disposed on and covers the rear surface 100B of the display panel 100. The front surface 300A of the back cover 300 is disposed at least on the upper portion of the rear surface 200B of the core plate 200 and covers at least the upper portion of the rear surface 200B of the core plate 200. A resin 400 (which can also be referred to herein as a resin strip 400 or a resin layer 400) is coated between the display panel 100 and the core plate 200 such that the display panel 100 is attached to the top surface 200C of the core plate 200 by the resin 400.

[0082] FIG. 5 is a cross-sectional view of the display device 10 along FIG. 1A line II-II' of FIG. 1. Referring to FIG. 5 , the display panel 100 can include a substrate 11 (as described above with reference to FIG. 2 ) on which a light emitting element is disposed, an encapsulation glass 12, a decorative film 14, and an adhesive layer 13. In some embodiments, the decorative film 14 can be attached in the form of a film or can be printed in the form of an ink. The display panel 100 can be attached to the inner flat portion 204 of the core plate 200 by the adhesive layer 13 disposed on the rear surface 100B of the display panel 100. The core plate 200 includes a protrusion 203 protruding toward the encapsulation glass 12. The protrusion 203 is a protrusion or ridge extending away from the inner flat portion 204 of the core plate 200 toward the encapsulation glass 12, which can be located at an outer peripheral edge of the core plate 200. The protrusion 203 of the core plate 200 enables connection between the core plate 200, the rear cover 300, and the encapsulation glass 12 of the display panel 100. Specifically, the encapsulation glass 12 can be spaced apart from the inner flat portion 204 of the core plate 200 by an amount corresponding to the thickness of the display panel 100. As further described below, the protrusion 203 occupies this space to enable a reliable and firm connection between the core plate 200 and the encapsulation glass 12, while also being able to accommodate a connection portion with the rear cover 300. Alternatively, the substrate 11 can also be referred to as the display panel 100, and the encapsulation glass 12 and the decorative film 14 are disposed on the front surface of the display panel 100.

[0083] The rear cover 300 can have a bonding portion 303 bonded to the protrusion 203 to cover the protrusion 203. Specifically, as FIG. 5As shown, the coupling portion 303 can have an inverted U shape that interfaces with and generally surrounds the protrusion 203 of the core plate 200. Thus, the coupling portion 303 defines a channel that accommodates the protrusion 203 of the core plate 200. The resin 400 can be coated on one surface (e.g., an outer surface) of the coupling portion 303 of the back cover 300 that couples with the protrusion 203 of the core plate 200, so that the back cover 300 can be adhered to the package glass 12 to which the decorative film 14 has been attached via the resin 400. Thus, the display panel 100 is coupled to the inner flat portion 204 by the adhesive 13, and the package glass 12 is coupled to the protrusion 203 and the back cover 300 by the resin 400 at a position spaced apart from the interface between the display panel 100 and the adhesive 13. Due to this structure, a separate fixing screw or tape that couples the display panel 100, the core plate 200, and the back cover 300 together can be omitted, thus enabling minimization of the edge area. Minimization of the edge area enables a design that can minimize the bezel area of the display device 10. When this embodiment is applied, the bezel area can be reduced by an amount of about 12 mm compared to the case where a screw or tape is applied. Specifically, the space for coupling with a screw can be about 17 mm, whereas in the structure of the present embodiment, since the screw is omitted, the space for coupling can be about 5 mm to 5.5 mm. The resin 400 can be coated into the space for coupling that is reduced by the application of the present embodiment, so that the package glass 12 can be attached to the back cover 300. Referring to FIG. 5 , the back cover 300 can be manufactured in a shape such that the bottom 305 of the back cover 300 is spaced apart from the bottom face or rear surface 200B of the core plate 200, to enable smooth fitting of the core plate 200 into the back cover 300.

[0084] FIG. 6 is a detailed perspective view showing a state in which the protrusion 203 of the core plate 200 and the back cover 300 are coupled to each other via the resin 400, with the resin 400 disposed therebetween. In FIG. 6 , the display device 10 is shown immediately before the display panel 100 is attached to the back cover 300 and the core plate 200, to help understanding of the present disclosure.

[0085] FIG. 7A and FIG. 7B are enlarged views of the area A and the area B of FIG. 4 , respectively. FIG. 7AThe protruding portions 203 and the flat portions 204 of the core plate 200 are shown in more detail. Specifically, protrusions 210 and grooves 220 can be formed in the top surface 205 of the protruding portions 203 of the core plate 200. As described below, the protrusions 210 and the grooves 220 in the top surface 205 of the protruding portions 203 assist in bonding the core plate 200 to the back cover 300. The protrusions 210 are arranged to be spaced apart from each other by a certain pitch corresponding to the grooves 220, and the grooves 220 are arranged to be spaced apart from each other by a certain pitch corresponding to the protrusions 210. That is, the protrusions 210 and the grooves 220 are alternately arranged with each other. In an embodiment, the protrusions 210 and the grooves 220 are formed on the entire top surface 205, or can be formed on selected portions of the top surface 205. In addition, the respective protrusions 210 and grooves 220 on the top surface 205 can have the same size and shape, or can have different sizes and shapes.

[0086] Referring to FIG. 7B The bonding portions 310 and the openings 320 can be formed in the edge region 305 of the back cover 300 to correspond to the grooves 220 and the protrusions 210 of the core plate 200, respectively. For example, the respective protrusions 210 of the core plate 200 are inserted into the respective openings 320 of the back cover 300, and the respective bonding portions 310 of the back cover 300 are inserted into the respective grooves 220 of the core plate 200. The bonding portions 310 and the openings 320 are alternately arranged with each other. Accordingly, the core plate 200 and the back cover 300 can be bonded to each other by the protrusions 210 and the grooves 220 of the core plate 200 and the corresponding bonding portions 310 and openings 320 in the back cover 300, for example, by a friction fit, a press fit, or with the resin 400, without separate fasteners (e.g., screws or tape). The bonding robustness and processability can be adjusted based on the density of the protrusions 210 and the grooves 220 of the core plate 200 and the density of the bonding portions 310 and the openings 320 of the back cover 300. More detailed information thereof will be described in the description of FIG. 9 of the core plate 200 and the back cover 300 before the display panel 100 is attached to the core plate 200 and the back cover 300.

[0087] FIG. 8 is FIG. 7A is a magnified sectional view of part C of FIG. 2 and shows a perspective view of the protrusions 210 and the grooves 220 of the protruding portions 203 of the core plate 200. The bonding portions 310 of the back cover 300 can correspond to the grooves 220 of the core plate 200, and the openings 320 of the back cover 300 can correspond to the protrusions 210 of the core plate 200.

[0088] FIG. 9 is a top plan view of a state in which the core plate 200 and the back cover 300 are bonded to each other before the display panel 100 is attached to the core plate 200 and the back cover 300.

[0089] Referring to FIG. 9The flat portion 204 can be in direct contact with the display panel 100. The protruding portion 203 can be in contact with the encapsulation glass 12. The protruding portion 203 can be divided into three regions, i.e., a first region, a second region, and a third region. The protruding portion 203 can be disposed only around the top outer peripheral edge of the core plate 200 and not disposed in the inside of the flat portion 204 of the core plate 200 that accommodates the display device and combines the display device to the vehicle or the module. The protruding portion 203 can be mainly divided into three regions based on the inflection points. For example, based on the direction of FIG. 9 , the protruding portion 203 can be divided into the first region that is substantially flat as a top region or a center region, the second region as a left side region, and the third region as a right side region. The boundary of the regions can correspond to the inflection points in the curvature of the round corners of the outer peripheral edge of the core plate 200. For example, based on the direction of FIG. 9 , the first region terminates at the right side of the core plate 200 at the inflection point of the curved upper right edge of the core plate 200, and the third region starts at the inflection point and continues to the end of the bottom edge of the core plate 200. The same applies to the interface between the first region and the second region on the left side of the core plate 200. The density of the protrusions 210 and the grooves 220 in the first region can be higher than the density of the protrusions 210 and the grooves 220 in each of the second region and the third region. The bonding portions 310 and the openings 320 of the back cover 300 can be disposed to correspond to the grooves 220 and the protrusions 210 of the core plate 200, respectively. When the density of the protrusions 210 and the grooves 220 in the first region is higher than the density of the protrusions 210 and the grooves 220 in each of the second region and the third region, the bonding robustness and the workability can be improved at the same time. For example, in the first region in which the density of the protrusions 210 and the grooves 220 is high, the core plate 200 and the back cover 300 are in contact with each other in a large surface area, so that the bonding robustness can be improved and a stronger connection is formed in the first region. When the density of the protrusions 210 and the grooves 220 in each of the second region and the third region is low, the worker can bond the core plate 200 and the back cover 300 to each other in each of the second region and the third region in an easier manner than the first region.

[0090] FIG. 10A and FIG. 10B are FIG. 9 cross-sectional views of one or more embodiments of the bonding between the protrusions 210 of the core plate 200 and the openings 320 of the back cover 300 shown in FIGS. 1A and 1B. Referring to FIG. 10A , the back cover 300 can be disposed to cover the side surface 203A and the top surface 203B of the protruding portion 203 of the core plate 200. The protrusions 210 of the protruding portion 203 and the openings 320 of the back cover 300 can be directly bonded to each other in a state in which the protrusions 210 are inserted into the openings 320, so that the core plate 200 and the back cover 300 can be bonded to each other. Referring to FIG. 10BThe rear cover 300 can be provided to cover both opposite side surfaces 203A, 203C and the top surface 203B of the protrusion 203. The first protrusion 210 can be formed on the top surface of the protrusion 203 and the second protrusion 230 can be formed on the inner side surface of the protrusion 203. Specifically, in a state in which the display panel 100 is combined to the core plate 200, the second protrusion 230 can face the display panel 100. A second opening 330 corresponding to the second protrusion 230 can be defined in the inner side vertical portion of the rear cover 300. A first opening 320 can be defined in the top portion of the rear cover 300. Accordingly, the second protrusion 230 can be inserted into the second opening 330 to provide an additional combined structure in addition to the combination between the first protrusion 210 and the first opening 320 and to further improve the connection between the core plate 200 and the rear cover 300.

[0091] With regard to FIG. 9 , continuing to refer to FIG. 10A and FIG. 10B , FIG. 10B the structure of FIG. 9 may be applied to the first area, while the structure of FIG. 10A may be applied to each of the second and third areas of FIG. 9 . Accordingly, a relatively strong combined force can be provided to a greater first area, while a relatively weak combined force for simplifying the assembly process can be applied to each of the second and third areas having a relatively small coupling area compared to the first area. The second protrusion 230 can have a wedge shape such that the rear cover 300 and the core plate 200 can be completely fixed to each other when the second opening 330 and the second protrusion 230 are combined to each other.

[0092] Referring to FIG. 10A and FIG. 10B , the rear cover 300 can be provided to be spaced apart from the bottom or rear surface 200B of the core plate 200 by a selected distance. A portion of the rear cover 300 spaced apart from the bottom of the core plate 200 by the selected distance can extend at a selected angle with respect to the bottom of the core plate 200. In an embodiment, the selected distance can be less than 1 mm, from 1 mm to 10 mm, or greater than 10 mm, including intermediate values. The selected angle can be between 0 degrees and 90 degrees, including intermediate values. Accordingly, the core plate 200 and the rear cover 300 can be more smoothly combined to each other. However, the present disclosure is not limited thereto. In some embodiments, the rear cover 300 can be in close contact with the bottom of the core plate 200.

[0093] FIG. 11A is a perspective view showing a combined structure of the core plate 200 and the rear cover 300, based on the embodiments of FIG. 10A and FIG. 10B as described above. FIG. 11B is a top view of a state in which the core plate 200 and the rear cover 300 are combined to each other. Referring toFIG. 11A The core plate 200 has the inner flat portion 204 and the protruding portion 203 which are combined to the rear cover 300. The protrusion 210 and the groove 220 can be formed in the top surface of the protruding portion 203. The combining portion 310 of the rear cover 300 can correspond to the groove 220, and in FIG. 11A , the groove 220 is covered. The second protrusion 230 can be formed on the inner side surface 203C of the protruding portion 203 which faces the display panel 100. The second opening 330 can be defined in the inner side vertical portion of the rear cover 300 to correspond to the second protrusion 230. The structure having the second protrusion 230 can refer to FIG. 10B . The structure without the second protrusion 230 can refer to FIG. 10A .

[0094] Referring to FIG. 11B , the size of the planar area of each of the protrusion 210 and the opening 320 can be based on the size in the Y direction which is the combining direction of the core plate 200 and the rear cover 300 and the size in the X direction which is perpendicular to the combining direction. For example, the protrusion 210 can have a width of about 40 mm in the X axis direction. The opening 320 corresponding thereto can have a width of about 40.2 mm in the X axis direction. Although the X direction width of the protrusion 210 and the X direction width of the opening 320 can be substantially the same, an edge gap in the X direction can be formed in the opening 320 to make the combination between the core plate 200 and the rear cover 300 smoother. The Y axis direction width of the protrusion 210 can be about 2.5 mm. The width of the opening 320 corresponding thereto in the Y axis direction can be about 3 mm. Although the Y direction width of the protrusion 210 and the Y direction width of the opening 320 can be substantially the same, an edge gap in the Y direction can be formed in the opening 320 to make the combination between the core plate 200 and the rear cover 300 smoother.

[0095] FIG. 12A and FIG. 12B shows additional embodiments related to the shape of each of the protrusion 210 of the protruding portion 203 of the core plate 200 and the opening 320 of the combining portion of the rear cover 300. Referring to FIG. 12A , a plan view of the core plate 200 and the rear cover 300 combined with each other is shown. The circular protrusion 210a and the circular opening 320a are combined with each other. With FIG. 7A or the rectangular protrusion 210 shown in FIG. 11, each of the circular protrusion 210a and the circular opening 320a has a circular shape. Thus, in the process in which the core plate 200 and the rear cover 300 are combined with each other, stress can be uniformly distributed around the circular protrusion pattern. In the rectangular protrusion pattern, stress can be concentrated on the right angle corners. Thus, the square corner portions can be damaged due to the stress concentration. In contrast, in FIG. 12AWhen the Y-axis direction coupling between the core plate 200 and the rear cover 300 is performed, stress can be uniformly distributed around the protrusion without being locally concentrated due to the shape of the circular protrusion 201a among the circular protrusions 201a shown in FIG. 10. Stress can be uniformly distributed around the circular opening 320a of the core plate 200. Accordingly, damage to the protrusion and the opening that can occur in the coupling process between the core plate 200 and the rear cover 300 can be minimized.

[0096] Referring to FIG. 12B , a coupling plane at which the core plate 200 and the rear cover 300 are coupled to each other is shown. In this regard, the diamond-shaped protrusion 210b and the diamond-shaped opening 320b are coupled to each other. In contrast to FIG. 7A or the rectangular protrusion 210 shown in FIG. 11, each of the diamond-shaped protrusion 210b and the diamond-shaped opening 320b has a smaller planar area perpendicular to the Y-axis direction when the core plate 200 and the rear cover 300 are coupled to each other. Accordingly, a smaller fastening force for coupling the core plate 200 and the rear cover 300 to each other can be used. Due to this advantage, the diamond-shaped protrusion 210b can be used.

[0097] FIG. 13A to FIG. 13B Another example of a coupling structure of the core plate 200 and the rear cover 300 is shown. In this regard, the diamond-shaped protrusion 210b and the diamond-shaped opening 320b are coupled to each other. FIG. 11A and FIG. 11B and FIG. 12A and FIG. 12B In the structure of the core plate 200 and the rear cover 300, it can be difficult to detach the core plate 200 and the rear cover 300 from each other. For example, a quality problem can occur in the coupling process of the core plate 200 and the rear cover 300 or after the display device is attached to a vehicle or a component. When a quality problem occurs, it can be advantageous to detach the core plate 200 and the rear cover 300 from each other. To this end, the design of the core plate 200 and the rear cover 300 can be modified.

[0098] Referring to FIG. 13A , two second protrusions 230a can be formed on the vertical side surface of the protruding portion 203 of the core plate 200 and extend vertically downward and can be spaced apart from each other. Accordingly, a second recess 240 can be defined between the two second protrusions 230a and can extend vertically. FIG. 13B The rear cover 300 has a coupling portion 310, a vertically extending portion 340, and a coupling head 350 formed at a lower end of the vertically extending portion 340. Referring to FIG. 11AThe second protrusion 230 of the core plate 200 has a wedge shape and is combined with the second opening 330 of the rear cover 300, and in the present embodiment, the second recess 240 is provided on the protruding portion 203, the vertical extension 340 can be inserted into the second recess 240, and the wedge-shaped combination head 350 can be engaged with the lower end of the second protrusion 230a. Thus, the core plate 200 and the rear cover 300 can be detached from each other by lifting the extension 340 and the combination head 350 connected thereto, thereby removing it from the second recess 240. In one embodiment, the extension 340 and the combination head 350 of the rear cover 300 and the rear cover 300 can generally be made of a material having a high elasticity and can be manufactured using a double injection molding scheme, so that the extension 340 and the combination head 350 have elasticity for the above-described removable combination function.

[0099] FIG. 14A and FIG. 14B Another example of a combination structure between the core plate 200 and the rear cover 300 is illustrated. The core plate 200 and the rear cover 300 can be removably combined with each other. Referring to FIG. 14A At least one second protrusion 230b is formed on a vertical side surface of the protruding portion 203 facing the display panel 100. The second protrusion 230b can have a circular shape. Referring to FIG. 14B To correspond to the second protrusion 230b provided in FIG. 14A , the rear cover 300 has a vertical extension 340 extending downward from the combination portion 310 of the rear cover 300. A second opening 360 can be defined at the lower end of the vertical extension 340. The vertical extension 340 can be made of a material having elasticity, and the second opening 360 has a circular shape.
