Description

Technical Field

[0001] This disclosure relates to a display device, and more specifically, to a display device having a structure with improved space efficiency. Background Technology

[0002] The content described in this background section is only for providing background information on this disclosure and does not constitute prior art.

[0003] As we enter the information age of comprehensive development, display devices that visually express electrical information signals are rapidly evolving. In response, various display devices that are high-performance, thin, lightweight, and low-power have been developed.

[0004] Display devices include liquid crystal displays (LCDs), quantum dot (QD) displays, field emission displays (FEDs), electrowetting displays (EWDs), and organic light-emitting diode (OLEDs).

[0005] A display device can be formed by joining together a structure in which a display for displaying images, at least one printed circuit board for controlling the operation of the images reproduced on such display and for supplying power, and a cover for housing the printed circuit board therein. Summary of the Invention

[0006] The display can be manufactured in a relatively small size, thus miniaturizing the device. Accordingly, the area of ​​the cover can correspond to the area of ​​the display.

[0007] However, considering the size and number of various components and the installation space, printed circuit boards are limited in size, which restricts the ability to manufacture printed circuit boards smaller than the area that the cover can accommodate.

[0008] Furthermore, when multiple printed circuit boards (PCBs) are mounted in a display device, the total area occupied by the PCBs may exceed the area that the cover can accommodate. In this case, the area of ​​the PCBs must be reduced to accommodate them within the cover; however, as mentioned above, there is a problem that the size of the PCBs cannot be easily reduced.

[0009] Therefore, one object of this disclosure is to provide a display device whose structure can effectively accommodate a printed circuit board therein.

[0010] Furthermore, one object of this disclosure is to provide a display device having the following structure: in this structure, even when the total area of ​​the multiple printed circuit boards exceeds the accommodating area of ​​the cover, the cover can still accommodate all of the multiple printed circuit boards.

[0011] Furthermore, one object of this disclosure is to provide a display device whose structure allows a plurality of printed circuit boards to overlap each other in the front-back direction and to be arranged at positions spaced apart from each other.

[0012] The purpose of this disclosure is not limited to the objectives described above. Other objectives and advantages not mentioned in this disclosure may be understood based on the following description and may be more clearly understood based on embodiments of this disclosure. Furthermore, it will be readily understood that the objectives and advantages of this disclosure can be achieved using the apparatus and combinations thereof as shown in the claims.

[0013] An embodiment of a display device may include a display, a cover, a printed circuit board, and a mounting portion.

[0014] A monitor can display images or videos and can be formed largely as a whole from a rectangular thin plate.

[0015] The cover can be attached to the display and has a space provided. The cover can be integrally formed into a rectangular box shape and can include a first housing and a second housing.

[0016] The first housing is positioned to face the mounting portion and can form the bottom surface of the cover. The second housing can be formed to bend from the first housing at the edge of the first housing and can define the space of the cover.

[0017] The printed circuit board can be electrically connected to the display and can have a controller for controlling the operation of the images or videos displayed on the display.

[0018] Printed circuit boards can be housed in a space and can comprise multiple printed circuit boards. Printed circuit boards can have different sizes and shapes. For example, a printed circuit board may include a first board, a second board, and a third board.

[0019] The first board can be positioned at the rear of the monitor. In other words, the first board can be positioned at the location on the board closest to the monitor.

[0020] The second plate can be positioned behind the first plate and can be formed into a generally rectangular shape. The third plate can be positioned behind the second plate, can be formed into a generally rectangular shape, and can have a larger area than the second plate.

[0021] In a display device, in order to accommodate multiple panels with relatively large dimensions and a total area exceeding the accommodating area of ​​the cover, the panels can be accommodated in the cover because at least a portion of the panels are configured to overlap each other in the front-back direction of the display device.

[0022] The mounting section can be attached to the display and housed in a space. The mounting section can be generally formed in the shape of a plate and can be attached to the rear surface of the display.

[0023] A first mounting protrusion, on which a printed circuit board is mounted, may be formed on the mounting portion. The first mounting protrusion may protrude from the rear surface of the mounting portion toward the rear of the mounting portion.

[0024] Multiple printed circuit boards (i.e., a first board, a second board, and a third board) can be mounted on a first mounting protrusion. Furthermore, the first mounting protrusion may include multiple mounting slots defined at positions spaced apart from each other along the length of the first mounting protrusion, such that the printed circuit boards are spaced apart from each other.

[0025] To securely mount multiple plates, multiple first mounting protrusions can be provided. In this regard, the multiple first mounting protrusions can be positioned on the mounting portion at intervals from each other in a direction intersecting the length direction of the first mounting protrusions.

[0026] Multiple mounting slots can be positioned at intervals between each other in the front-to-back direction of the display device. A first plate, a second plate, and a third plate can be mounted on each of the multiple mounting slots. Therefore, the front-to-back distance between the plates can be determined by the front-to-back distance between the mounting slots.

[0027] A first fastening groove for fastening may be defined in the first mounting protrusion. The first fastening groove may be defined as recessed from the end of the first mounting protrusion and defined along the length direction of the first mounting protrusion, and a fastening mechanism such as a bolt may be inserted into the first fastening groove.

[0028] The first housing may have a through-joint portion defined at a position corresponding to a first fastening groove, and a fastening mechanism is inserted into the through-joint portion. The fastening mechanism may fasten to the through-joint portion of the first housing and the first fastening groove of the first mounting protrusion, such that the cover and the mounting portion can be securely engaged with each other.

[0029] The first mounting protrusion may include a first small-diameter portion, a second small-diameter portion, a third small-diameter portion, a first large-diameter portion, and a second large-diameter portion. In the first mounting protrusion, the small-diameter portions and the large-diameter portions are alternately formed along the length of the first mounting protrusion, and the portions of the first mounting protrusion corresponding to the small-diameter portions form mounting grooves, such that multiple mounting grooves can be defined to be spaced apart from each other along the length of the first mounting protrusion.

[0030] The first small-diameter portion may have a mounting groove in which the first plate is mounted. Since the first plate is located at the foremost part of the display device compared to the other plates, the first small-diameter portion may be formed at the foremost part of the first mounting protrusion compared to the other small-diameter portions.

[0031] The second small-diameter portion may be formed at a position spaced apart from the first small-diameter portion in the length direction of the first mounting protrusion, and may have a mounting groove in which the second plate is mounted. The second small-diameter portion may be formed between the first small-diameter portion and the third small-diameter portion in the front-rear direction of the first mounting protrusion.

[0032] The third small-diameter portion can be formed at a position spaced apart from the second small-diameter portion in the length direction of the first mounting protrusion, and the third plate is mounted in the third small-diameter portion. The large-diameter portion may not be provided at the end of the third small-diameter portion.

[0033] Each plate may have a recess or a through portion for fitting into a mounting slot. A first recess may be defined in the first plate, a second recess may be defined in the second plate, and a first through portion may be defined in the third plate.

[0034] To ensure a more secure attachment of the second and third plates to the mounting portion, a second mounting protrusion may be formed on the mounting portion. The second mounting protrusion, together with the first mounting protrusion, can be used to attach the second and third plates to the mounting portion.

[0035] The second mounting protrusion can be formed to protrude from the rear surface of the mounting portion toward the rear of the display device. Multiple second mounting protrusions can be provided, and these protrusions can be formed at spaced-apart positions on the mounting portion.

[0036] The second or third plate can be engaged with the second mounting protrusion by fastening a coupling mechanism, such as a bolt, to the second or third plate while it is in contact with the end of the second mounting protrusion. Therefore, the second mounting protrusion can have a second fastening groove defined as recessed from the end of the second mounting protrusion, defined along the length of the second mounting protrusion, and the fastening mechanism is inserted into the second fastening groove.

[0037] The second mounting protrusion may include a first protrusion and a second protrusion. The first protrusion may engage with and support the second plate. The second protrusion may engage with and support the third plate.

[0038] The first or second protrusion may include multiple first or second protrusions to more firmly support the second or third plate. Multiple first or second protrusions may be formed at spaced-apart locations within the mounting portion.

[0039] Each of the second and third plates may have a fastening hole for engagement with each of the first and second protrusions via a coupling mechanism.

[0040] The through-joint may include a pressure-applying portion and a third fastening hole. The pressure-applying portion may be formed to be recessed from the rear surface of the first housing and protrude from the front surface of the first housing to press against a surface of the printed circuit board. The third fastening hole may be defined to extend through the pressure-applying portion, and a fastening mechanism may be inserted into the third fastening hole.

[0041] One embodiment of the display device may include: a display; a cover, the cover being engaged with the display and having a space therein; a plurality of printed circuit boards, the plurality of printed circuit boards being housed in the space; and a mounting portion, the mounting portion being engaged with the display, housed in the space, and having a first mounting protrusion thereon, wherein the printed circuit boards are mounted on the first mounting protrusion, and the first mounting protrusion may include a plurality of mounting slots, wherein the printed circuit boards are respectively mounted in the plurality of mounting slots, wherein the plurality of mounting slots are defined at positions spaced apart from each other along the length direction of the first mounting protrusion, such that the plurality of printed circuit boards are positioned spaced apart from each other.

[0042] In the display device according to this disclosure, since multiple printed circuit boards are configured to at least partially overlap each other, relatively large printed circuit boards can be easily accommodated within the cover. Therefore, even when the total area of ​​the multiple printed circuit boards exceeds the accommodating area of ​​the cover, the printed circuit boards can still be easily accommodated within the cover, thereby improving the space efficiency of the cover.

[0043] Furthermore, since the display device has a structure unaffected by the size of the printed circuit board, there is no need to excessively reduce the size of the printed circuit board. Additionally, performance degradation of the display device caused by excessive omission of components and circuit structures during the process of reducing the size of the printed circuit board can be suppressed.

[0044] Furthermore, in the display device according to this disclosure, since the plurality of mounting slots defined in the first engagement protrusion are spaced apart from each other in the front-rear direction of the display device, the printed circuit boards mounted in the mounting slots are spaced far enough apart from each other to suppress damage and performance degradation caused by interference or contact between the boards.

[0045] The effects of this disclosure are not limited to those described above, and those skilled in the art will clearly understand other effects not mentioned from the following description.

[0046] The objectives, technical solutions, and effects described above in this disclosure do not specifically describe the basic features of the claims. Therefore, the scope of the claims is not limited by the objectives, technical solutions, and effects described above in this disclosure. Attached Figure Description

[0069] Figure 1 This is an exploded perspective view of a display device according to one embodiment. Figure 2 This is a view showing a portion of a display device cut off according to one embodiment. Figure 3 This is a perspective view showing a display 100 and a mounting portion 400 according to one embodiment.

[0070] For example, the display device according to the embodiments may include a liquid crystal display (LCD), a quantum dot (QD) display device, a field emission display (FED), an electrowetting display (EWD), and an organic light-emitting diode (OLED), etc. However, this disclosure is not limited thereto.

[0071] The display device according to the embodiment may include a display 100, a cover 200, a printed circuit board 300, and a mounting part 400.

[0072] The display 100 is capable of displaying images or videos, and its display scheme is the same as described above. The display 100 may be formed generally as a whole from a rectangular thin plate.

[0073] The cover 200 can be engaged with the display 100 and has a space therein for accommodating components. For example, the display 100 and the cover 200 can be engaged with each other by means such as bolts, adhesives or laser melting methods, but this disclosure is not limited thereto.

[0074] The cover 200 may be made of a metallic material such as aluminum that has good corrosion resistance, durability and manufacturability, or of a plastic material that is easy to injection mold, but this disclosure is not limited thereto.

[0075] The cover 200 can be integrally formed into a rectangular box shape and may include a first housing 210 and a second housing 220. The first housing 210 is configured to face the mounting portion 400 described below and may form the bottom surface of the cover 200.

[0076] The second housing 220 may be formed to bend from the first housing 210 at the edge of the first housing 210 and may define a receiving space for the printed circuit board 300 therein. The second housing 220 may be coupled to the display 100 so as to contact the edge of the rear surface of the display 100. The printed circuit board 300 may be housed in the space defined by the second housing 220.

[0077] The printed circuit board 300 can be electrically connected to the display 100 and can have a controller for controlling the operation of the images or videos displayed on the display 100.

[0078] Various components and wiring, including active and manual components, for receiving power from an external power source and supplying power to the display 100, transmitting data to the display 100, and controlling its operation can be formed on the printed circuit board 300.

[0079] Printed circuit board 300 can be housed within cover 200 and can include multiple printed circuit boards. The multiple printed circuit boards 300 can have different sizes and shapes. For example, printed circuit board 300 can include a first board 310, a second board 320, and a third board 330. Although not shown in the figures, wiring for electrically connecting the first board 310, the second board 320, and the third board 330 to each other can be connected to these boards.

[0080] The first board 310, the second board 320, and the third board 330 can perform different functions or the same function in the display device.

[0081] The first plate 310 can be disposed at the rear of the display 100. That is, the first plate 310 can be disposed at the position closest to the display 100 among these plates. The first plate 310 can be formed into a rectangular shape with a smaller width and a larger vertical dimension compared to the second plate 320 and the third plate 330.

[0082] The first board 310 can be directly electrically connected to the display 100. Therefore, the display device may include a connector 110 for electrically connecting the first board 310 and the display 100 to each other. In this regard, the connector 110 may include multiple connectors and may be made of a flexible material for easy folding.

[0083] The second plate 320 may be disposed behind the first plate 310 and may be formed in a substantially rectangular shape. The third plate 330 may be disposed behind the second plate 320, may be formed in a substantially rectangular shape, and may have a larger area than the second plate 320.

[0084] The total area of ​​the first plate 310, the second plate 320, and the third plate 330 may be larger than the area of ​​the display 100 and the first housing 210. Therefore, it may be difficult to accommodate all of the first plate 310, the second plate 320, and the third plate 330 within the cover 200.

[0085] In this scenario, each board can be accommodated within the cover 200 by reducing its size (i.e., the area of ​​each board). However, due to the reduced size of each board, some components and wiring necessary for each board to function properly must be omitted. This could potentially degrade the performance of the boards, and consequently, the overall performance of the display device.

[0086] For the reasons mentioned above, it is difficult to reduce the size of the plate, thus requiring a structure for accommodating a plate with a relatively large area within the cover 200. In this embodiment, a display device is proposed whose structure can securely accommodate a relatively large area plate within the cover 200 without reducing the size of the plate.

[0087] In an embodiment, in order to accommodate multiple plates having relatively large dimensions and a total area exceeding the accommodating area of ​​the cover 200, the plates are accommodated in the cover 200 because at least a portion of the plates are configured to overlap each other in the front-back direction of the display device.

[0088] In other words, at least a portion of the first plate 310, the second plate 320, and the third plate 330 can be configured to overlap each other in the front-back direction of the display device.

[0089] For example, at least a portion of the second plate 320 may be configured to overlap with the first plate 310 in the front-rear direction of the display device. Furthermore, at least a portion of the third plate 330 may be configured to overlap with the second plate 320 in the front-rear direction of the display device.

[0090] The boards need to be spaced apart from each other in the front-to-back direction at an appropriate distance so that the components mounted on the individual boards do not collide with each other and there is no electrical short circuit in the overlapping parts of the boards due to contact between them.

[0091] Therefore, in a display device, multiple panels need to be spaced apart from each other so that they do not contact each other when they overlap in the front-to-back direction. For this structure, the display device according to an embodiment may have a mounting section 400.

[0092] The mounting portion 400 can be engaged to the display 100 and housed within the cover 200. The mounting portion 400 can be generally formed in the shape of a plate and can be engaged to the rear surface of the display 100. For example, the mounting portion 400 and the display 100 can be bonded to each other by adhesive, but this disclosure is not limited thereto.

[0093] A first mounting protrusion 410, on which the printed circuit board 300 is mounted, may be formed on the mounting portion 400. The first mounting protrusion 410 may protrude from the rear surface of the mounting portion 400 toward the rear of the mounting portion 400.

[0094] Multiple printed circuit boards 300 (i.e., first board 310, second board 320, and third board 330) can be mounted on the first mounting protrusion 410. In addition, the first mounting protrusion 410 may include multiple mounting slots 411, which are defined at positions spaced apart from each other in the length direction of the first mounting protrusion 410, such that the printed circuit boards 300 are spaced apart from each other.

[0095] The first mounting protrusion 410 can be configured such that its length direction points towards the front-rear direction of the display device. Multiple first mounting protrusions 410 can be provided to securely mount multiple panels. In this regard, the first mounting protrusions 410 can be provided on the mounting portion 400 at positions spaced apart from each other in a direction intersecting with the length direction of the first mounting protrusions 410.

[0096] The structure of the first mounting protrusion 410 will be described in detail below with reference to the accompanying drawings. Figure 4 yes Figure 3 An enlarged cross-sectional perspective view of a portion of the structure. Figure 5 This is a view of the display device with the cover 200 omitted from one embodiment. Figure 6 yes Figure 5 An enlarged cross-sectional perspective view of a portion of the structure.

[0097] like Figure 4 As shown, multiple mounting slots 411 can be positioned at locations spaced apart from each other in the front-rear direction of the display device.

[0098] The first plate 310, the second plate 320, and the third plate 330 can be mounted on each of the plurality of mounting slots 411. Therefore, the distance between the plates in the front-back direction can be determined by the distance between the mounting slots 411 in the front-back direction.

[0099] In this respect, a first fastening groove 412 for fastening may be defined in the first mounting protrusion 410. The first fastening groove 412 may be defined as recessed from the end of the first mounting protrusion 410 and defined along the length direction of the first mounting protrusion 410, and a fastening mechanism such as a bolt may be inserted into the first fastening groove 412.

[0100] Furthermore, the first housing 210 may have a through-joint 211 defined at a position corresponding to the first fastening groove 412, and a fastening mechanism is inserted into the through-joint 211. The fastening mechanism can fasten to the through-joint 211 of the first housing 210 and the first fastening groove 412 of the first mounting protrusion 410, so that the cover 200 and the mounting portion 400 can be securely engaged with each other.

[0101] like Figure 4 As shown, the first mounting protrusion 410 may include a first small-diameter portion 413, a second small-diameter portion 414, a third small-diameter portion 415, a first large-diameter portion 416, and a second large-diameter portion 417. In this respect, a small-diameter portion refers to a portion with a relatively small diameter, and a large-diameter portion refers to a portion with a relatively large diameter.

[0102] In an embodiment, in the first mounting protrusion 410, small-diameter portions and large-diameter portions are alternately formed along the length of the first mounting protrusion 410, and the portions of the first mounting protrusion 410 corresponding to the small-diameter portions form mounting grooves 411, such that a plurality of mounting grooves 411 can be defined to be spaced apart from each other along the length of the first mounting protrusion 410. In this regard, the length of each small-diameter portion measured along the length of the first mounting protrusion 410 can be a value corresponding to the thickness of each plate.

[0103] The first small diameter portion 413 may have a mounting groove 411 in which the first plate 310 is mounted. Since the first plate 310 is located at the foremost part of the display device compared to the other plates, the first small diameter portion 413 may be formed at the foremost part of the first mounting protrusion 410 compared to the other small diameter portions.

[0104] The second small diameter portion 414 may be formed at a position spaced apart from the first small diameter portion 413 in the length direction of the first mounting protrusion 410, and may have a mounting groove 411 in which the second plate 320 is mounted. The second small diameter portion 414 may be formed between the first small diameter portion 413 and the third small diameter portion 415 in the front-rear direction of the first mounting protrusion 410.

[0105] The third small diameter portion 415 can be formed at a position spaced apart from the second small diameter portion 414 in the length direction of the first mounting protrusion 410, and the third plate 330 is mounted in the third small diameter portion 415. For example... Figure 4 As shown, the large-diameter portion may not be provided at the end of the third small-diameter portion 415.

[0106] Therefore, in the third plate 330, the first through portion 331 can be defined such that the third small diameter portion 415 is inserted therein. That is, unlike the first plate 310 and the second plate 320, which move in the lateral direction of the display device and are fitted into the first mounting protrusion 410, the third plate 330 moves in the longitudinal direction of the display device and is mounted on the third small diameter portion 415 to fit into the first mounting protrusion 410.

[0107] The first large-diameter portion 416 can be disposed between the first small-diameter portion 413 and the second small-diameter portion 414. The second large-diameter portion 417 can be disposed between the second small-diameter portion 414 and the third small-diameter portion 415. The large-diameter portions can be spaced apart from each other in the length direction of the first mounting protrusion 410.

[0108] Therefore, the plates mounted on the various small-diameter portions are arranged to be spaced apart from each other in the length direction of the first mounting protrusion 410, so that the plates can be securely accommodated in the cover 200 without interfering with or contacting each other.

[0109] The length of each large-diameter portion, measured along the length of the first mounting protrusion 410, can be set as the distance between the two plates in the front-to-back direction. Therefore, taking into account shape characteristics (e.g., the thickness of each plate) and other factors (e.g., the dimensions of the components mounted on each plate), the length of each large-diameter portion can be designed to an appropriate value so that the plates do not contact or interfere with each other.

[0110] In one example, each plate may have a recess or a through portion for fitting into the mounting slot 411. A first recess 311 may be defined in the first plate 310, a second recess 321 may be defined in the second plate 320, and a first through portion 331 may be defined in the third plate 330.

[0111] The first plate 310 may include a first recess 311, which is defined to be recessed from the edge of the first plate 310 and mounted on a first small diameter portion 413. The second plate 320 may include a second recess 321, which is defined to be recessed from the edge of the second plate 320 and mounted on a second small diameter portion 414.

[0112] Each of the first recess 311 and the second recess 321 can be defined as an approximately semi-circular recess shape at the edge of each circuit board. Therefore, as the first recess 311 and the second recess 321 are respectively fitted into the first small diameter portion 413 and the second small diameter portion 414 that form the mounting groove 411, the first plate 310 and the second plate 320 can move in the lateral direction of the display device and engage with the first mounting protrusion 410.

[0113] The third plate 330 may include a first through portion 331, which is defined to extend through the third plate 330 and be mounted on the third small diameter portion 415. Therefore, as the third small diameter portion 415 is inserted into the first through portion 331, the third plate 330 can move in the forward direction of the display device and engage with the first mounting protrusion 410.

[0114] In one example, to more securely mount the second plate 320 and the third plate 330 onto the mounting portion 400, a second mounting protrusion 420 may be formed on the mounting portion 400. The second mounting protrusion 420 can be used together with the first mounting protrusion 410 to mount the second plate 320 and the third plate 330 onto the mounting portion 400.

[0115] The mounting portion 400 may further include a second mounting protrusion 420, which is formed to protrude in the front-rear direction of the display device, and at least one of the second plate 320 and the third plate 330 is mounted on the second mounting protrusion 420.

[0116] The second mounting protrusion 420 can be formed to protrude from the rear surface of the mounting portion 400 toward the rear of the display device. A plurality of second mounting protrusions 420 can be provided, and the plurality of second mounting protrusions 420 can be formed at positions spaced apart from each other on the mounting portion 400.

[0117] Since one surface of the second plate 320 or the third plate 330 contacts the end of the second mounting protrusion 420, the second plate 320 or the third plate 330 can be supported by the second mounting protrusion 420. The second plate 320 or the third plate 330 can be engaged with the second mounting protrusion 420 because a connecting structure such as a bolt is fastened to the second plate 320 or the third plate 330 while the second plate 320 or the third plate 330 contacts the end of the second mounting protrusion 420.

[0118] Therefore, the second mounting protrusion 420 may have a second fastening groove 421, which is defined as recessed from the end of the second mounting protrusion 420, defined along the length direction of the second mounting protrusion 420, and a fastening mechanism is inserted into the second fastening groove 421. With the engagement mechanism fastened to the second fastening groove 421, the second mounting protrusion 420 and the second plate 320 or the third plate 330 can engage with each other.

[0119] The second mounting protrusion 420 may include a first protrusion 420a and a second protrusion 420b. The first protrusion 420a may engage with and support the second plate 320. The second protrusion 420b may engage with and support the third plate 330.

[0120] The first protrusion 420a or the second protrusion 420b may include multiple first protrusions or multiple second protrusions to more firmly support the second plate or the third plate. The multiple first protrusions 420a or multiple second protrusions 420b may be formed at positions spaced apart from each other in the mounting portion 400.

[0121] The lengths of the first protrusion 420a and the second protrusion 420b may be different from each other. In the display device, the second plate 320 may be disposed in front of the third plate 330, and the third plate 330 may be disposed behind the second plate 320.

[0122] Therefore, the first protrusion 420a supporting the second plate 320 can be relatively short, and the second protrusion 420b supporting the third plate 330 can be relatively long, so that the second plate 320 is located in front of the third plate 330. That is to say, the second protrusion 420b can be formed to be longer than the first protrusion 420a.

[0123] Each of the second plate 320 and the third plate 330 may have a fastening hole for engagement with each of the first protrusion 420a and the second protrusion 420b by means of an engagement mechanism.

[0124] The second plate 320 may include a first fastening hole 322, which is defined at a position corresponding to the first protrusion 420a, and a fastening mechanism is inserted into the first fastening hole 322. The third plate 330 may include a second fastening hole 332, which is defined at a position corresponding to the second protrusion 420b, and a fastening mechanism is inserted into the second fastening hole 332.

[0125] The engagement mechanism can be fastened to the second fastening groove 421 of the first protrusion 420a and the first fastening hole 322 of the second plate 320 so that the second plate 320 can engage with the first protrusion 420a. Furthermore, the engagement mechanism can be fastened to the second fastening groove 421 of the second protrusion 420b and the second fastening hole 332 of the third plate 330 so that the third plate 330 can engage with the second protrusion 420b.

[0126] The length difference between the first protrusion 420a and the second protrusion 420b can define the front-to-back spacing between the second plate 320 and the third plate 330. Therefore, the length difference between the first protrusion 420a and the second protrusion 420b can be set to a value corresponding to the length of the second large diameter portion 417.

[0127] Figure 7 This is an enlarged cross-sectional perspective view of a portion of a display device according to one embodiment, with a cover 200 installed therein.

[0128] like Figure 7As shown, the through joint 211 may include a pressure portion 2111 and a third fastening hole 2112. The pressure portion 2111 may be formed to be recessed from the rear surface of the first housing 210 and protrude from the front surface of the first housing 210 to press a surface of the printed circuit board 300. The third fastening hole 2112 may be defined to extend through the pressure portion 2111, and a fastening mechanism may be inserted into the third fastening hole 2112.

[0129] When the engagement mechanism is fastened to the third fastening hole 2112 and the third plate 330 and the cover 200 are engaged with each other, the forward-protruding pressure part 2111 can squeeze the third plate 330 and space the rear surface of the third plate 330 and the front surface of the first housing 210 apart from each other.

[0130] The pressure application portion 2111 can define the space between the third plate 330 and the first housing 210, and through this space, it can prevent components mounted on the rear surface of the third plate 330 and having a meaningful volume from contacting the first housing 210 and being interfered with by the first housing 210.

[0131] Figure 8 This is a view showing the process of installing the first board 310 in a display device. Figure 9 This is a view showing the process of installing the second board 320 in the display device. Figure 10 This is a view showing the process of installing the third board 330 in a display device. Figure 11 This is a view showing the process of installing the cover 200 in a display device.

[0132] Figure 8 , Figure 9 and Figure 10 The arrows shown indicate the direction of board movement during the assembly of the display device. The assembly sequence of the display device according to an embodiment will be described below with reference to the accompanying drawings.

[0133] like Figure 8 As shown, the first plate 310 moves in the lateral direction of the mounting portion 400 so that the first recess 311 of the first plate 310 is inserted into the first small diameter portion 413 of the first mounting protrusion 410, so that the first plate 310 engages with the first mounting protrusion 410.

[0134] Next, as Figure 9 As shown, the second plate 320 moves in the lateral direction of the mounting portion 400 so that the second recess 321 of the second plate 320 is inserted into the second small diameter portion 414 of the first mounting protrusion 410, so that the second plate 320 engages with the first mounting protrusion 410.

[0135] Furthermore, the second plate 320 is engaged with the first protrusion 420a by inserting the engagement mechanism into the second fastening groove 421 of the first protrusion 420a and the first fastening hole 322 of the second plate 320.

[0136] Next, as Figure 10 As shown, the third plate 330 moves in the forward direction of the mounting portion 400 so that the third small diameter portion 415 of the first mounting protrusion 410 is inserted into the first through portion 331 of the third plate 330, so that the third plate 330 engages with the first mounting protrusion 410.

[0137] Furthermore, the third plate 330 is engaged with the second protrusion 420b by inserting the engagement mechanism into the second fastening groove 421 of the second protrusion 420b and the second fastening hole 332 of the third plate 330.

[0138] Next, as Figure 11 As shown, the cover 200 covers the rear surface of the display 100, and the engagement mechanism is inserted into the first fastening groove 412 of the first housing 210 through the engagement portion 211 and the first engagement protrusion, so that the cover 200 engages with the first engagement protrusion.

[0139] If necessary, adhesives or the like can be used to attach the rear surface of the display 100 and the end of the second housing 220 of the cover 200 to each other in order to securely bond the cover 200 and the display 100 together, but this is not a necessary step.

[0140] In this embodiment, since the multiple printed circuit boards 300 are configured to at least partially overlap each other, relatively large printed circuit boards 300 can be easily accommodated in the cover 200. Therefore, even when the total area of ​​the multiple printed circuit boards 300 exceeds the accommodating area of ​​the cover 200, the printed circuit boards 300 can still be easily accommodated in the cover 200, thereby improving the space efficiency of the cover 200.

[0141] Furthermore, since the display device has a structure unaffected by the size of the printed circuit board 300, there is no need to excessively reduce the size of the printed circuit board 300. Additionally, performance degradation of the display device caused by excessive omission of components and circuit structures during the reduction of the printed circuit board 300's size can be suppressed.

[0142] In the embodiment, since the plurality of mounting slots 411 defined in the first engagement protrusion are spaced apart from each other in the front-rear direction of the display device, the printed circuit boards 300 mounted in the mounting slots 411 are spaced far enough apart from each other to suppress damage and performance degradation caused by interference or contact between the boards.

[0143] The present disclosure as described above is not limited to the embodiments and drawings presented. It will be apparent to those skilled in the art that various substitutions, modifications, and alterations can be made without departing from the spirit and concept of the present disclosure. Therefore, the scope of the present disclosure is defined by the following claims, and all variations or modifications derived from the meaning and scope of the claims and their equivalents should be interpreted as being included within the scope of this disclosure.
