[0046] The features of various exemplary embodiments of the present disclosure can be partially or wholly combined. As those skilled in the art will clearly understand, various interactions and operations are possible in the technical field. The various exemplary embodiments can be practiced individually or in combination.

[0047] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0048] Figure 1 is an exploded perspective view of a display device 1 according to an embodiment.

[0049] Referring to Figure 1 , the display device 1 according to an embodiment can be applied to a smart phone, a mobile phone, a tablet personal computer (PC), a personal digital assistant (PDA), a portable multimedia player (PMP), a television, a game console, a wristwatch-type electronic device, a head-mounted display, a monitor of a PC, a laptop computer, a car navigation system, a car dashboard, a digital camera, a camcorder, an outdoor billboard, an electronic display board, a medical device, an examination device, various home appliances such as a refrigerator and a washing machine, or an Internet of Things (IoT) device. In the present specification, a television will be described as an example of the display device 1. The television can have a high resolution or an ultra-high resolution such as HD, UHD, 4K, or 8K.

[0050] In addition, the display device 1 according to the embodiments can be variously classified according to a display method. For example, the display device 1 can be classified as an organic light emitting diode display device, an inorganic electroluminescence (EL) display device, a quantum dot light emitting display device (QED), a micro light emitting diode display device, a nano light emitting diode display device, a plasma display panel (PDP), a field emission display (FED) device, a cathode ray tube (CRT) display device, a liquid crystal display (LCD) device, or an electrophoretic display (EPD) device. An organic light emitting diode display device will be described below as an example of the display device 1. Unless a specific distinction is required, the organic light emitting diode display device applied to the embodiments will be simply shortened as a display device. However, the embodiments are not limited to the organic light emitting diode display device, and other display devices listed above or known in the art can also be applied within the scope of sharing the technical spirit.

[0051] The display device 1 can include a vapor cavity 20, a display panel 10, and a front cover 40. The vapor cavity 20, the display panel 10, and the front cover 40 can be disposed, for example, along a third direction DR3. The display panel 10 can be disposed between the vapor cavity 20 and the front cover 40.

[0052] The display panel 10 can be a self-emissive display panel. The display panel 10 as a self-emissive display panel can be an organic light emitting display panel. However, the present disclosure is not limited thereto, and other types of display panels 10, such as a liquid crystal display panel, a quantum dot organic light emitting display panel, a quantum dot liquid crystal display panel, a quantum nano light emitting display panel, and a micro light emitting diode display panel, can also be applied.

[0053] The display panel 10 can include a substrate SUB (see Figure 4 ) and a display layer DU (see Figure 4 ) disposed on the substrate SUB. Detailed structures of the display panel 10 will be described later with reference to Figure 4

[0054] The vapor cavity 20 can transfer heat generated from the display panel 10 and the driving board 30 (see Figure 4 ) to another space inside the display device 1 or the outside. For example, the vapor cavity 20 can dissipate heat generated from the display panel 10 and the driving board 30 to an internal space of the front cover 40 or the outside of the display device 1.

[0055] ​At least a portion of the vapor chamber 20 can surround the display panel 10. For example, at least a portion of the vapor chamber 20 can surround side surfaces of the display panel 10. Accordingly, the vapor chamber 20 can protect the side surfaces of the display panel 10. According to an embodiment, the vapor chamber 20 can include a bottom plate and side walls SW surrounding the side surfaces of the display panel 10. The side walls SW can include a first side wall SW1, a second side wall SW2, a third side wall SW3, and a fourth side wall SW4 disposed at four edges of the vapor chamber 20, respectively. The first side wall SW1 to the fourth side wall SW4 can be integrally formed with the vapor chamber 20. As in the example illustrated in Figure 1

[0056] According to an embodiment, the first side wall SW1 to the fourth side wall SW4 can be integrally formed.

[0057] According to an embodiment, the first side wall SW1 to the fourth side wall SW4 and the vapor chamber 20 can include a metal such as aluminum.

[0058] The display device 1 including the heat dissipation member such as the vapor chamber 20 can quickly disperse or dissipate heat generated from the driving board 30.

[0059] The front cover 40 and the vapor chamber 20 can surround the display panel 10 and the driving board 30. The front cover 40 can protect the display panel 10 and the driving board 30 from external impacts.

[0060] The front cover 40 can include a highly transparent material to allow light emitted from the display panel 10 to pass therethrough. For example, the front cover 40 can include a polymer resin such as polyimide or glass. In an embodiment, the front cover 40 can include an opening open in a region overlapping with a display area DPA (see Figure 2 ).

[0061] Each of the vapor chamber 20, the display panel 10, and the front cover 40 can include a short side extending in a first direction DR1 and a long side extending in a second direction DR2. The present disclosure is not limited thereto.

[0062] At least a portion of the vapor chamber 20 can surround side surfaces of the front cover 40. For example, the side walls SW of the vapor chamber 20 can surround the side surfaces of the front cover 40. As in​Figure 1 In the example illustrated in the middle, when the front cover 40 has a quadrangular shape including four side surfaces (e.g., a first side surface, a second side surface, a third side surface, and a fourth side surface), the first side wall SW1 to the fourth side wall SW4 of the vapor chamber 20 can be placed to face the side surfaces of the front cover 40. For example, the first side wall SW1 can face the first side surface of the front cover 40, the second side wall SW2 can face the second side surface of the front cover 40, the third side wall SW3 can face the third side surface of the front cover 40, and the fourth side wall SW4 can face the fourth side surface of the front cover 40.

[0063] The front cover 40 is optional.

[0064] According to the embodiment, the vapor chamber 20 can perform the functions of the covers (e.g., side covers and a rear cover) of the display device 1 as well as the heat dissipation function. Accordingly, it is possible to reduce the bezel size of the display device 1, thereby implementing a slim structure. In addition, according to the embodiment, since the rear cover and the side covers are not needed, it is possible to reduce the manufacturing cost of the display device 1. In addition, since the vapor chamber 20 is exposed to the outside without being covered by the rear cover, it is possible to improve the heat dissipation effect of the vapor chamber 20.

[0065] Figure 2 is a plan view of the display device 1 according to an embodiment.

[0066] Referring to Figure 2 The display device 1 according to the embodiment can have a quadrangular shape in a plan view. For example, the display device 1 can have a rectangular shape, but the present disclosure is not limited thereto.

[0067] In some embodiments, when the display device 1 is a television, a long side thereof extends in the second direction DR2. However, the present disclosure is not limited thereto, and the long side can also extend in the first direction DR1, or the display device 1 can be rotatably installed so that the long side can be variably extended in the first direction DR1 or the second direction DR2.

[0068] The display device 1 can include a display area DPA and a non-display area NDA. The display area DPA can be an effective area in which an image is displayed. The display area DPA can have a rectangular shape similar to the overall shape of the display device 1 in a plan view, but the present disclosure is not limited thereto.

[0069] The display area DPA can include a plurality of pixels PX. The plurality of pixels PX can be arranged in a matrix form. Each of the plurality of pixels PX can be rectangular or square in a plan view. However, the present disclosure is not limited thereto, and each of the plurality of pixels PX can also have a rhombus shape having each side inclined with respect to the sides of the display device 1. The pixels PX can include pixels PX that provide light of different colors (or wavelengths). For example, the pixels PX can include, but are not limited to, red pixels that provide red light, green pixels that provide green light, and blue pixels that provide blue light. The color pixels can be alternately arranged in a stripe or honeycomb type.

[0070] The non-display area NDA can be arranged around the display area DPA. The non-display area NDA can form a bezel of the display device 1. The non-display area NDA can completely or partially surround the display area DPA.

[0071] In some embodiments, the display area DPA can have a rectangular shape, and the non-display area NDA can be arranged adjacent to four sides of the display area DPA. For example, the non-display area NDA can include a first non-display area NDA1 arranged adjacent to a first long side of the display device 1 (which extends in the second direction DR2 and is adjacent to the driving chip DIC in the first direction DR1), Figure 2 a second non-display area NDA2 arranged adjacent to a second long side of the display device 1 (which extends in the second direction DR2 parallel to the first long side in the first direction DR1), Figure 2 a third non-display area NDA3 arranged adjacent to a first short side of the display device 1 (which extends in the first direction DR1 and is adjacent to the scan driver SDR in the second direction DR2), and Figure 2 a fourth non-display area NDA4 arranged adjacent to a second short side of the display device 1 (which extends in the first direction DR1 parallel to the first short side in the second direction DR2). Figure 2

[0072] The driving circuit or driving element for driving the display area DPA can be arranged in the non-display area NDA. For example, a pad portion can be provided on the substrate SUB in the first non-display area NDA1 and the second non-display area NDA2 of the display panel 10, and an external device EXD can be mounted on a pad electrode of the pad portion. Each of the plurality of external devices EXD can include a circuit member CCM (see Figure 4 ) that will be described later. Examples of the external device EXD can include a connection film, a printed circuit board, a driving chip DIC, a connector, and a wiring connection film. For another example, a scan driver SDR directly formed on the substrate SUB of the display panel 10 can be arranged in the third non-display area NDA3.

[0073] Figure 3 is a circuit diagram of the display device 1 according to an embodiment.​

[0074] Referring to Figure 3 A plurality of lines can be disposed on the substrate SUB of the display device 1. The plurality of lines can include scan lines SCL, sensing signal lines SSL, data lines DTL, reference voltage lines RVL, and first power lines ELVDL.

[0075] The scan lines SCL and the sensing signal lines SSL can extend in the second direction DR2. The scan lines SCL and the sensing signal lines SSL can be connected to a scan driver SDR. The scan driver SDR can include a driving circuit composed of a plurality of circuit layers. The scan driver SDR can be disposed in the third non-display area NDA3. However, the present disclosure is not limited thereto, and the scan driver SDR can also be disposed in the fourth non-display area NDA4, or can also be disposed in both the third non-display area NDA3 and the fourth non-display area NDA4. The scan driver SDR can be connected to a signal connection line CWL, and at least one end of the signal connection line CWL can form a pad WPD_CW in the first non-display area NDA1 and / or the second non-display area NDA2, and thus can be connected to an external device EXD (see Figure 2 ).

[0076] In the drawings, the first direction DR1 and the second direction DR2 intersect each other. For example, the first direction DR1 and the second direction DR2 can be orthogonal to each other. In addition, the third direction DR3 can be referred to as a "vertical direction" and intersects the first direction DR1 and the second direction DR2; for example, the third direction DR3 can be orthogonal to the first direction DR1 and the second direction DR2. In the present specification, a direction indicated by an arrow of each of the first direction DR1 to the third direction DR3 can be referred to as one side, and an opposite direction can be referred to as the other side.

[0077] The data lines DTL and the reference voltage lines RVL can extend in the first direction DR1 intersecting the second direction DR2. The first power lines ELVDL can include a portion extending in the second direction DR2. The first power lines ELVDL can also include a portion extending in the first direction DR1. The first power lines ELVDL can have a mesh structure, but the present disclosure is not limited thereto.

[0078] The wiring pads WPD can be arranged on at least one end of each of the data lines DTL, the reference voltage lines RVL, and the first power lines ELVDL. Each of the wiring pads WPD can be arranged in the pad portion PDA of the non-display area NDA. In an embodiment, the wiring pads WPD of the data lines DTL (hereinafter referred to as "data pads WPD DT") can be arranged in the pad portion PDA of the first non-display area NDA1, and the wiring pads WPD of the reference voltage lines RVL (hereinafter referred to as "reference voltage pads WPD RV") and the wiring pads WPD of the first power lines ELVDL (hereinafter referred to as "first power pads WPD ELVD") can be arranged in the pad portion PDA of the second non-display area NDA2. Alternatively, the data pads WPD DT, the reference voltage pads WPD RV, and the first power pads WPD ELVD can all be arranged in the same area, for example, in the first non-display area NDA1. An external device EXD (see Figure 2 ) can be mounted on the wiring pads WPD as described above. The external device EXD can be mounted on the wiring pads WPD by an anisotropic conductive film, ultrasonic welding, or the like.

[0079] Each pixel PX on the substrate SUB of the display panel 10 can include a pixel driving circuit. The above-described lines can transmit a driving signal to each pixel driving circuit while passing through each pixel PX or surrounding each pixel PX. The pixel driving circuit can include a transistor and a capacitor. The number of transistors and capacitors in each pixel driving circuit can be variously changed.

[0080] Figure 4 is a cross-sectional view of the display device 1 according to an embodiment. For example, Figure 4 may be a cross-sectional view taken along the line I-I' of Figure 1 .

[0081] The vapor chamber 20 can include a first plate 21, a second plate 22, a first flange 211, a second flange 212, a third flange 221, a fourth flange 222, and side walls SW. In Figure 4 , the first side wall SW1 and the second side wall SW2 among the first to fourth side walls SW1 to SW4 facing each other in the first direction DR1 are illustrated.

[0082] The first plate 21, the first flange 211, and the second flange 212 can be integrally formed to constitute a bottom plate of the vapor chamber 20.

[0083] The second plate 22, the third flange 221, the fourth flange 222, the first extension portion EX1, the second extension portion EX2, the first side wall SW1, and the second side wall SW2 can be integrally formed.

[0084] The first plate 21 can have a quadrangular shape in a plan view. The first plate 21 can include a stainless steel material having excellent corrosion resistance.

[0085] The second plate 22 can have a quadrangular shape in a plan view. The second plate 22 can be disposed on the first plate 21 to face the first plate 21 in the third direction DR3. For example, as Figure 4 illustrated in FIG. 2, the second plate 22 can be disposed between the first plate 21 and the first adhesive member 50. The second plate 22 can include the stainless steel material described above.

[0086] The first plate 21 and the second plate 22 can be placed to face each other in a plane defined by the first direction DR1 and the second direction DR2. In some embodiments (e.g., see Figure 5 ), the first plate 21 and the second plate 22 can be spaced apart from each other in the third direction DR3. A space can be provided between the first plate 21 and the second plate 22. A fluid can be disposed in the space between the first plate 21 and the second plate 22. The fluid can be a liquid such as water. Heat generated from the display panel 10 and the driving plate 30 can be transferred to the vapor chamber 20 to evaporate the fluid within the vapor chamber 20. For example, the temperature of the fluid can be increased by the heat, and the fluid can evaporate and condense at the increased temperature. When these evaporation and condensation processes are repeated, heat from heat generating components of the display device 1 such as the display panel 10 and the driving plate 30 can be released to the outside.

[0087] The first flange 211 can be disposed at an edge of the first plate 21, and the second flange 212 can be disposed at another edge of the first plate 21. The first flange 211 and the second flange 212 can be integrally formed with the first plate 21. The second flange 212 can be bent in an L shape.

[0088] The third flange 221 can be disposed at an edge of the second plate 22, and the fourth flange 222 can be disposed at another edge of the second plate 22. The third flange 221 and the fourth flange 222 can be integrally formed with the second plate 22. The fourth flange 222 can be bent in an L shape. When each of the fourth flange 222 and the second flange 212 is bent in an L shape, a distance between the display panel 10 and the fourth flange 222 can increase. Accordingly, it is possible to secure a space in which the driving plate 30 can be placed between the substrate SUB of the display panel 10 and the fourth flange 222.

[0089] The first flange 211 of the first plate 21 and the third flange 221 of the second plate 22 can contact each other, and the second flange 212 of the first plate 21 and the fourth flange 222 of the second plate 22 can contact each other. For example, the first flange 211 and the third flange 221 can be coupled to each other by a method such as welding, and the second flange 212 and the fourth flange 222 can be coupled to each other by a method such as welding. The first plate 21 and the second plate 22 can be coupled to each other by the first flange 211, the second flange 212, the third flange 221, and the fourth flange 222. The inside of the vapor cavity 20 can be sealed by the coupling of the first flange 211, the second flange 212, the third flange 221, and the fourth flange 222. In other words, the space between the first plate 21 and the second plate 22 can be sealed by the coupling of the first flange 211, the second flange 212, the third flange 221, and the fourth flange 222.

[0090] The first extension portion EX1 can extend from the third flange 221. For example, as illustrated in FIG. 2A, the first extension portion EX1 can extend from the third flange 221 in the opposite direction of the first direction DR1 (hereinafter referred to as "first opposite direction"). Figure 4

[0091] The second extension portion EX2 can extend from the fourth flange 222. For example, as illustrated in FIG. 2B, the second extension portion EX2 can extend from the fourth flange 222 in the first direction DR1. Figure 4

[0092] The first side wall SW1 can be disposed on the first extension portion EX1. For example, the first side wall SW1 can extend (or protrude) from an edge of the first extension portion EX1 in the third direction DR3. The upper surface of the first side wall SW1 and the upper surface of the display panel 10 (for example, the upper surface of the display layer DU) can be located on the same plane. For example, assuming that there is a virtual plane including the interface between the first plate 21 and the second plate 22, the distance measured orthogonally from the virtual plane to the upper surface of the first side wall SW1 is the same as the distance measured orthogonally from the virtual plane to the upper surface of the display layer DU. The first side wall SW1 can face the side surface of the display panel 10. There can be a space between the first side wall SW1 and the side surface of the display panel 10 closest to the first side wall SW1.

[0093] ​​The second side wall SW2 can be disposed on the second extension portion EX2. For example, the second side wall SW2 can extend (or protrude) from an edge of the second extension portion EX2 in the third direction DR3. An upper surface (e.g., an uppermost surface) of the second side wall SW2 and an upper surface (e.g., an uppermost surface of the display layer DU) of the display panel 10 can be located on the same plane. As described above, the upper surface of the second side wall SW2 and the upper surface of the first side wall SW1 are located on the same plane due to the fact that the upper surface of the first side wall SW1 and the upper surface of the display layer DU are also located on the same plane. The upper surfaces of the first side wall SW1 to the fourth side wall SW4 can be located on the same plane. In other words, the distances from the above-mentioned virtual plane to the uppermost surfaces of the first side wall SW1 to the fourth side wall SW4 in the third direction DR3 can all be the same. The second side wall SW2 can face a side surface of the display panel 10. There can be a space between the second side wall SW2 and the side surface of the display panel 10 closest to the second side wall SW2.

[0094] In Figure 4 In an embodiment of the display panel 10, the side walls SW include outward-facing surfaces of the vapor chamber 20. In a plan view, the first side wall SW1 to the fourth side wall SW4 can form a closed curve around the drive board 30, the first adhesive member 50, the second adhesive member 60, the circuit member CCM, the substrate SUB, and the display layer DU.

[0095] The first adhesive member 50 can be disposed between the vapor chamber 20 and the display panel 10. For example, the first adhesive member 50 can be disposed between the second plate 22 of the vapor chamber 20 and the substrate SUB of the display panel 10. The first adhesive member 50 can bond the second plate 22 and the substrate SUB to each other.

[0096] The drive board 30 can be disposed between the vapor chamber 20 and the display panel 10. For example, the drive board 30 can be disposed between the fourth flange 222 of the vapor chamber 20 and the substrate SUB of the display panel 10 at an edge of the display panel 10 (or the substrate SUB).

[0097] The drive board 30 and the display panel 10 can be physically and electrically connected to each other through the circuit member CCM. For example, the pad portion PDA of the drive board 30 and the pad portion PDA of the substrate SUB can be physically and electrically connected to each other through the circuit member CCM.

[0098] The second adhesive member 60 can be disposed between the drive board 30 and the display panel 10. For example, the second adhesive member 60 can be disposed between the drive board 30 and the substrate SUB of the display panel 10.

[0099] The second adhesive member 60 can bond the drive board 30 and the substrate SUB to each other.

[0101] As Figure 5 and Figure 6 illustrated in
