However, it should be understood that although in one embodiment, two elements are described below as "connected", similar elements may be "coupled" in alternative embodiments, and vice versa. Therefore, although the schematic diagrams shown here describe exemplary arrangements of elements, additional intermediate elements, devices, components or members may still exist in an actual embodiment.

[0065] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0066] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0067] In the description of the present application, a first feature being “on” or “under” a second feature may include the first and second features being in direct contact with each other, or the first and second features being in contact with each other not directly but via another feature therebetween.

[0068] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0069] In related technologies, the display device's system circuitry and other heat-generating components are fixed to the same backplane as the panel. Heat dissipated from this system continuously affects the panel's temperature. Furthermore, the system's heat source is fixed, causing certain locations on the panel to maintain high temperatures. Without a stable and efficient heat dissipation method, system heat is difficult to dissipate elsewhere, leading to heat accumulation and significant temperature variations across the panel, inconsistent aging, significant color variations, and a reduced lifespan.

[0070] The present application provides a display device that separates the panel and the system part so that the heat generated by the system is not easily affected by the panel. The system part is located at the top of the display module. Due to the principle that heated air flows upward, the heat of the system part will be transferred to a higher position, further reducing the impact on the panel, improving the heat dissipation effect of the whole machine, ensuring the stability of the performance of the whole machine and extending its service life.

[0071] Reference Figure 1 and Figure 2 , Figure 1 FIG. 1 shows a schematic diagram of a display device. Figure 2An exploded view of a display device is shown. In one embodiment of the present application, a display device is provided.

[0072] In this embodiment, the display device includes a support assembly 1, a display module 2, and a control system assembly 3. The support assembly 1 includes a base 11 and a bracket 12, which is connected to the base 11; the display module 2 is mounted on the bracket 12; the control system assembly 3 is mounted on the bracket 12 and is located on the side of the display module 2 away from the base 11. The control system assembly 3 is connected to the display module 2 and is configured to drive the display module 2 to display.

[0073] The display module 2 may include an OLED panel. The display module 2 has a display side and a back side opposite the display side. The back side of the display module 2 is connected to the bracket 12. The display module 2 may be directly mounted to the bracket 12 or indirectly mounted to the bracket 12 via the control system component 3.

[0074] As an example, the bracket 12 may include a plurality of interconnected horizontal bars and vertical bars. Most of the back surface of the display module 2 is exposed by the bracket 12, thereby facilitating heat dissipation of the display module 2.

[0075] The base 11 may include a curved rod. The curved rod and the bracket 12 may be detachably connected or integrally connected. A plurality of pulleys may be provided at the bottom of the curved rod for ease of movement.

[0076] When the display device is assembled, the base 11 is located at the bottom of the device. Therefore, the control system component 3, located on the side of the display module 2 away from the base 11, is located at the top of the device. Because heated air tends to flow upward, the heat generated by the control system component 3 is conducted away from the display module 2.

[0077] It should be noted that control system assembly 3 comprises the entire system circuitry and serves as the control core of the entire device. Control system assembly 3 includes components that drive display module 2, such as the power supply assembly and control board. Control system assembly 3 also includes various auxiliary components, such as sound-generating elements and sensor elements.

[0078] According to the display device of the present application, by separating the display module 2 and the control system component 3, the heat generated by the control system component 3 is not easy to affect the display module 2, and the control system component 3 is located at the top of the display module 2. Due to the principle that heated air flows upward, the heat of the control system component 3 will be transferred to a higher position, further reducing the impact on the display module 2, improving the heat dissipation effect of the whole machine, ensuring the stability of the performance of the whole machine and extending its service life.

[0079] Reference Figure 3 , Figure 3An exploded schematic diagram of a display module 2 is shown. In some embodiments, the display module 2 includes a display panel, a back panel 23, a sealant 24, and a frame 25. The back panel 23 is mounted on the bracket 12 and is made of metal. The frame 25 is mounted on the edge of the back panel 23 and is located on the side of the back panel 23 away from the bracket 12. The display panel is attached to the side of the back panel 23 away from the bracket 12 and is located within the frame 25. The sealant 24 is filled between the display panel and the frame 25.

[0080] The backplate 23 is the primary structural component of the display module 2, supporting the entire display module 2. Made of metal, the backplate 23 offers excellent thermal conductivity, facilitating heat dissipation from the display module 2. The frame 25 and sealant 24 protect and secure the display panel. The sealant 24 also provides adhesion and shock absorption. The sealant 24 can be made of foam glue.

[0081] As an example, the material of the back plate 23 is aluminum.

[0082] Aluminum has excellent thermal conductivity and heat dissipation capabilities, with a thermal conductivity of up to 217W / mk. Using aluminum for backplate 23 allows uneven heat generation during display module 2 to be more quickly transferred across the entire backplate 23, achieving uniform heat dissipation. Furthermore, as a visual component, aluminum backplate 23 can undergo a variety of surface treatments, including oxidation and brushing.

[0083] As an example, the thickness of the back plate 23 ranges from 3 mm to 4 mm. For example, the thickness of the back plate 23 can be 3 mm, 3.5 mm, or 4 mm.

[0084] Taking aluminum as an example, the back plate 23 can have a thickness between 3 mm and 4 mm, which can also ensure a certain structural strength and meet the support requirements.

[0085] In some embodiments, the display panel includes a metal substrate, and the display module 2 further includes at least one magnet sheet 22 . The magnet sheet 22 is attached between the display panel and the back plate 23 .

[0086] As an example, a metal layer of about 0.2 mm may be provided in the substrate of the display panel. The metal layer can generate a polarization effect with the magnet sheet 22 and will not affect the luminous properties of the display panel.

[0087] The number of the magnet pieces 22 can be multiple and they are arranged in an array on the side of the back plate 23 facing the display panel. The magnet pieces 22 and the back plate 23 can be connected by gluing. The side of the back plate 23 facing the display panel can be provided with a score line (such as Figure 3 The wire frame in the middle back plate 23 ) and the scoring line serve to limit the position of the magnet sheet 22 .

[0088] In this embodiment, the magnet sheet 22 can adsorb the display panel, so that the display panel is subjected to more uniform force. While ensuring the adsorption force, it avoids internal hollowing, reduces the risk of the screen falling off, and has good reworkability, making it easy to disassemble and maintain.

[0089] In some embodiments, the thickness of the magnet sheet 22 ranges from 0.3 mm to 0.8 mm. For example, the thickness of the magnet sheet 22 can be 0.3 mm, 0.5 mm, or 0.8 mm.

[0090] In other embodiments, the display panel includes a glass substrate. Such a display panel can be directly attached to the back panel 23 by adhesive.

[0091] In some embodiments, the display module 2 further includes a back panel rib 26 . The back panel rib 26 is installed on a side of the back panel 23 facing the bracket 12 and is connected to the bracket 12 .

[0092] Backboard ribs 26 can be attached to backboard 23 using screws and can be arranged horizontally, vertically, or diagonally. They reinforce and straighten backboard 23 to prevent deformation. Backboard 23 is connected to bracket 12 via ribs 26. For example, ribs 26 can be connected to bracket 12 using screws.

[0093] In some embodiments, the display panel includes a display substrate 21, a row-direction printed circuit board 28, and signal connection lines 27. The row-direction printed circuit board 28 is connected to the display substrate 21 and is located on the side of the display substrate 21 close to the control system component 3. The orthographic projection of the row-direction printed circuit board 28 on the backplane 23 at least partially overlaps with the orthographic projection of the backplane rib 26 on the backplane. The signal connection lines 27 are respectively connected to the row-direction printed circuit board 28 and the control system component 3.

[0094] Signal connection line 27 is used to receive control signals from control system component 3 and transmit the control signals to row-direction printed circuit board 28 (also known as XPCB, X Printed Circuit Board), so that row-direction printed circuit board 28 drives display substrate 21 to display. The specific structure and principles of display substrate 21 and row-direction printed circuit board 28 are well-established technologies and will not be further described in this embodiment.

[0095] Signal connection lines 27 and row-direction printed circuit boards 28 are arranged near control system components 3 for easy connection. Similarly, backplane ribs 26 are also arranged near control system components 3, facilitating connection while also ensuring that the portion of the backplane corresponding to row-direction printed circuit boards 28 is not easily deformed, thereby preventing damage to row-direction printed circuit boards 28.

[0096] In some embodiments, the display module 2 further includes a protection frame 29 . The protection frame 29 covers the display panel and the row-direction printed circuit board 28 . The protection frame 29 serves to protect the row-direction printed circuit board 28 .

[0097] As an example, the assembly process of the display module 2 can be: fasten the frame 25 to the back panel 23 with screws, and attach the frame glue 24 to the frame 25; then adhere the magnet sheet 22 to the back panel 23; then adsorb the display panel on the magnet sheet 22; then fasten the protective frame 29 with screws; finally, fasten the back panel rib 26 to the back panel 23 with screws.

[0098] Reference Figure 4 , Figure 4 An exploded schematic diagram of a control system assembly 3 is shown. In some embodiments, the control system assembly 3 includes a housing and a circuit assembly. The housing bottom and the front and rear panels located on either side of the bottom along a first direction are integrally formed. The first direction is the front-to-back direction of the display module 2. The circuit assembly is mounted within the housing.

[0099] The bottom, front panel, and rear panel are integrally formed to form the housing 41. This integrated housing 41 provides excellent reliability and prevents deformation. The display side of the display module 2 is the front side, and the side facing away from the display side is the rear side. The front panel of the housing 41 is adjacent to the front side of the display module 2, while the rear panel of the housing 41 is adjacent to the rear side of the display module 2.

[0100] As an example, the circuit components may include but are not limited to a three-phase power socket 31, a first power board 32, a power touch panel 33, an infrared receiver 34, a second power board 35, a timing control board (TCON) board 36, a third power board 37, a frequency multiplier board 38 and a main board 39.

[0101] The circuit assembly may further include display accessories, such as a speaker 43, etc. Of course, the circuit assembly may further include some of the above components, which may be selected according to specific needs, and this embodiment does not impose any limitation thereto.

[0102] The box seat 41 can be provided with a plurality of limiting posts to facilitate fixing the circuit components. Figure 5 and Figure 6 , Figure 5 A cross-sectional view of the cassette holder 41 extruded along the width direction is shown. Figure 6 A cross-sectional view along the width direction of the limiting pillar after the box seat is formed is shown.

[0103] In some embodiments, the box bottom 41 includes a bent portion 50, which forms a receiving cavity 51 and a first opening 54 connected to the receiving cavity. The first opening 54 faces the display module 2, and the display module 2 partially extends into the receiving cavity 51 and is connected to the box bottom 41.

[0104] During installation, the top of the display module 2 can be inserted from one end of the box bottom 41 along the length of the box bottom 41. The top of the display module 2 can extend into the accommodating cavity 51 through the first opening 54. For example, the XPCB and backplane ribs 26 of the display panel 21 can extend into the accommodating cavity 51. The opening width of the accommodating cavity 51 can be smaller than the width of the accommodating cavity 51, thereby forming a bottom support portion on one side of the opening. When the display module 2 extends into the accommodating cavity 51, the backplane ribs 26 are supported on the bottom support portion.

[0105] In this embodiment, the curved portion 50 defines a first mounting cavity 52 and a second mounting cavity 53 arranged along a first direction within the housing. The first mounting cavity 52 is located near the front panel, while the second mounting cavity 53 is located near the rear panel. At least one speaker 43 is mounted in the first mounting cavity 52; the timing control board 36, the frequency multiplier board 38, and at least one power supply board are all mounted in the second mounting cavity 53. The timing control board 36, the frequency multiplier board 38, and the power supply board are arranged along a second direction, which is perpendicular to the first direction. The second direction corresponds to the left-right direction of the display module 2.

[0106] It is understood that when the display module 2 extends into the accommodating cavity 51, the first mounting cavity 52 is located in front of the display module 2, and the second mounting cavity 53 is located in the rear of the display module 2. The speaker 43 is located in front of the display module 2 to provide the best high-frequency sound effects, and the addition of a front counterweight centers the center of gravity at the support position to prevent tipping.

[0107] The box seat 41 may be installed with a speaker fixing seat 42 in the first installation cavity 52, and the speaker 43 is fixed to the speaker fixing seat 42. When the number of the speakers 43 is greater than or equal to two, each speaker 43 may also be arranged along the second direction.

[0108] As an example, the number of power boards can be three. The first power board 32, the second power board 35, the timing control board 36, the third power board 37, the frequency multiplier board 38 and the main board 39 can be arranged in the second installation cavity 53 along the second direction.

[0109] In some embodiments, the front panel has a second opening 44 that exposes the speaker 43. The box body also includes a sound grille 45 and a decorative panel 46. The sound grille 45 covers the second opening 44, and the decorative panel 46 covers the portion of the front panel not covered by the sound grille 45.

[0110] Reference Figure 7-Figure 9 , Figure 7 Shown is a front view of a cassette holder 41, Figure 8 Shown is a top view of a cassette holder 41, Figure 9 A rear view of a cassette holder 41 is shown.

[0111] As an example, the front plate of the cassette holder 41 is provided with two second openings 44 corresponding to the left and right sides of the center. The second openings 44 facilitate the sound output of the speaker 43 and improve the sound quality of the speaker 43 by covering the sound output mesh plate 45.

[0112] In some embodiments, the first mounting cavity 52 may also be provided with a power touch panel 33 and an infrared receiver 34. Furthermore, openings may be provided on the left and right ends of the front panel to expose the power touch panel 33 and the infrared receiver 34, which are then covered with a decorative panel 46 for protection and aesthetics.

[0113] In some embodiments, the three-phase power socket 31 is installed in the second mounting cavity 53, close to the power board, shortening wiring distances. The back panel can have an opening to expose the three-phase power socket 31 for easy power connection. Additionally, the back panel can have an opening to expose the mainboard IO port for easy signal cable connection.

[0114] In some implementations, a heat dissipation hole may be further provided in the middle of the rear plate to dissipate heat from the power board and the main board 39 in the second installation cavity 53 .

[0115] In some embodiments, a through hole 47 is provided at the bottom of the box, and the support assembly 1 includes a beam 13 and a connector 14, including a main body and an extension connected to the main body, the main body is arranged in the installation cavity, and the extension is connected to the bracket 12 through the through hole 47; the connector 14 main body is connected to the bottom of the box, and is connected to the display module 2 and the bottom of the box.

[0116] Perforation 47 can be provided in the first mounting cavity 52 or the second mounting cavity 53. The main body of crossbeam 13 and perforation 47 are located in the same mounting cavity. Bracket 12 can be provided with a groove, and the extension portion extends through perforation 47 into the groove and is securely connected to bracket 12. Connector 14 is used to connect the main body of the crossbeam to the bottom of the box, thereby securing the bottom of the box, and to connect the display module 2 to the bottom of the box, thereby securing the display module 2.

[0117] In some embodiments, the display module 2 , the beam 13 and the bent portion 50 are all provided with mounting holes, and the connector 14 includes screws that pass through the mounting holes of the display module 2 , the beam 13 and the bent portion 50 .
