[0066] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0067] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0068] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0069] like Figures 1 to 13 As shown, a display unit 100 is provided according to a first aspect of the present application, comprising: a lamp panel assembly 1; a housing assembly 3, the housing assembly 3 including a housing body 31 and a main control board 34, the lamp panel assembly 1 being connected to the housing assembly 3, a clearance space being formed on the housing body 31, the main control board 34 being disposed between the housing body 31 and the lamp panel assembly 1, and located within the clearance space; and a flexible circuit board 2, the lamp panel assembly 1 being connected to the lamp panel assembly 1 via the flexible circuit board 2.

[0070] The display unit 100 provided in this application embodiment includes a lamp board assembly 1, a cabinet assembly 3, and a flexible circuit board 2. The cabinet assembly 3 includes a cabinet body 31 and a main control board 34. During the assembly of the display unit 100, the lamp board assembly 1 is connected to the cabinet body 31. A clearance space is formed on the cabinet body 31 to accommodate the main control board 34. The main control board 34 is disposed within the clearance space. The lamp board assembly 1 is then connected to the main control board 34 via the flexible circuit board 2. The display unit 100 provided in this application uses the flexible circuit board 2 (FPC board) as the connection medium for communication and power supply. One end is bonded to the lamp board assembly 1, and the other end is connected to the main control board 34 (HUB board), replacing the board-to-board connector in related technologies, effectively reducing the screen thickness. The hollowed-out portion of the die-cast cabinet body 31 absorbs the volume of the main control board 34, reducing the thickness of the display unit 100, while providing a foundation for infinite screen splicing.

[0071] The display unit 100 provided in this application embodiment can significantly reduce the thickness of the display unit 100 to 10mm or less, which can meet the application scenarios with strict space requirements and is particularly suitable as an AM driving screen.

[0072] In some examples, the housing body 31 may have a positioning structure for positioning the lamp panel assembly 1, and the housing body 31 may be connected to the lamp panel assembly 1 by bolts 36.

[0073] In some examples, a portion of the flexible circuit board 2 can be bonded to the lamp panel assembly 1 via the adhesive layer 15 to further reduce the thickness of the display unit 100 and reduce the probability of the flexible circuit board 2 becoming loose.

[0074] The display unit 100 provided in this application embodiment uses a flexible circuit board 2 instead of a network cable and power cable for communication and power supply, which effectively reduces the thickness of the screen and realizes signal processing and transmission, facilitates maintenance, and achieves a reduction in screen thickness.

[0075] like Figure 10 As shown, in one feasible embodiment, the lamp panel assembly 1 includes: a plurality of lamp beads 12; a film layer 11, in which the plurality of lamp beads 12 are disposed, and the film layer 11 is arranged on the light-emitting surface of the lamp panel assembly 1; a lamp bead control board 13 and a lamp bead control chip 14, wherein the lamp beads 12 are connected to the lamp bead control board 13 and the lamp bead control chip 14 is connected to the lamp bead control board 13; wherein the lamp bead control board 13 is connected to the main control board 34 through a flexible circuit board 2.

[0076] In this technical solution, the structure of the lamp board assembly 1 is further provided. The lamp board assembly 1 may include multiple lamp beads 12, a film layer 11, a lamp bead control board 13 (PCB board), and a lamp bead control chip 14. Based on this, during the light emission process of the lamp board assembly 1, the lamp bead control chip 14 serves as the core control unit. The lamp bead control chip 14 receives control signals sent through the main control board 34 and the flexible circuit board 2, and sends the control signals to the lamp bead control board 13. The lamp bead control board 13 serves as an integrated control circuit and interface, and is connected to the lamp beads 12. It can realize the functions of driving, dimming, and communication of the lamp beads 12, thereby enabling the lamp tube assembly to display images. The film layer 11 can encapsulate the lamp beads 12, which can prevent the lamp beads 12 from being affected by moisture, oxidation, or mechanical damage, and improve the service life of the display unit 100.

[0077] In some examples, the LED 12 can be a Mini LED 12, a Micro LED 12, or a UMicro LED from Shenzhen Unilumin Technology Co., Ltd., with dimensions of 0.24*0.24*0.12mm. The LED control chip 14 can be fixed to the back using a surface mount method. There can be 4080 LED control chips, with one chip controlling four LEDs 12 to achieve pixel-to-pixel control. The packaged thickness of the LED control chip 14 is only 0.5mm. The communication and power input of the lamp board assembly 1 are connected using a flexible circuit board 2, which has a thickness of 0.1mm. The bonding process uses ACF constant temperature hot pressing bonding technology, which effectively reduces the thickness of the lamp board assembly 1, replacing the conventional floating connector communication method, improving the display effect, and further reducing the thickness of the display unit 100.

[0078] In one feasible implementation, the LED bead 12 is a MiniLED LED bead, a Micro LED LED bead, or an RGB display unit LED bead.

[0079] This technical solution further provides the specific type of the LED bead 12, which can be a Mini LED bead, a Micro LED bead, or an RGB display unit 100 bead, allowing for flexible selection based on requirements. Preferably, a Mini LED bead or a Micro LED bead can be selected, which helps to further reduce the thickness of the display unit 100.

[0080] like Figure 10 As shown, in one feasible embodiment, the housing assembly 3 further includes: a first connector 33, which is connected to the main control board 34, and the flexible circuit board 2 is connected to the main control board 34 through the first connector 33; wherein, the first connector 33 is arranged between the main control board 34 and the lamp board assembly 1.

[0081] In this technical solution, the structural composition of the cabinet assembly 3 is further provided. The cabinet assembly 3 may include a first connector 33, which is disposed on the motherboard. The flexible circuit board 2 is then connected to the first connector 33, so that the flexible circuit board 2 can be connected to the main control board 34 by plugging and unplugging. This simplifies the connection process between screens and between various components inside the screen. Compared with the traditional connection method, it reduces the space and complexity required for connection, further helps to realize the thin and light design of the screen, and at the same time ensures the high efficiency of large-volume data transmission.

[0082] In some examples, the first connector 33 can be an FPC connector (Flexible Printed Circuit Connector).

[0083] The display unit 100 provided in this embodiment has an LED bead 12 and a film layer 11 with a thickness of approximately 0.4 mm, an LED bead control board 13 with a thickness of approximately 2 mm, an LED bead control chip 14 with a thickness of approximately 0.4 mm, a first connector 33 with a thickness of approximately 2.5 mm, a main control board 34 with a thickness of approximately 1.0 mm, a basic thickness of the housing body 31 with a thickness of approximately 1.8 mm, a wire cover 35 on the back of the housing body 31 with a thickness of approximately 0.5 mm, and a gap of approximately 1.2 mm on the back of the main control board 34 for threading FPC cables and other components. This allows the overall thickness of the display unit 100 to be controlled at approximately 9.8 mm, resulting in a low thickness for the display unit 100.

[0084] like Figure 10 As shown, in one feasible embodiment, the enclosure assembly 3 further includes: a second connector 32, which is disposed between the enclosure body 31 and the main control board 34, and is connected to the main control board 34; an external line, one end of which is connected to the second connector 32, and the other end of which extends through the enclosure body 31.

[0085] In this technical solution, the enclosure assembly 3 may also include a second connector 32, which is arranged between the enclosure body 31 and the main control board 34. Based on this, external lines can be connected to the main control board 34 through the second connector 32, which facilitates the transmission of external signals to the main control board 34. The conventional enclosure side can be removed, and the external circuit can be used as a network port hardware for signal interconnection and a power supply line for power supply, which can further meet the requirement of reducing the overall assembly thickness.

[0086] like Figures 11 to 13 As shown, in one feasible embodiment, splicing members 5 are formed on the periphery of the cabinet body 31, and the two display units 100 are positioned or connected through the splicing members 5.

[0087] In this technical solution, splicing parts 5 can be formed on the periphery of the cabinet body 31. Based on this, multiple cabinet bodies 31 can be spliced ​​together by splicing parts 5, so that multiple display units 100 can be spliced ​​together. This allows users to set the size of the display screen 200 according to actual needs, which is more conducive to the promotion of display units 100.

[0088] like Figures 11 to 13 As shown, in one feasible embodiment, the splicing component 5 includes: a magnetic suction component 52 and / or a positioning post 51 disposed around the periphery of the box body 31.

[0089] In this technical solution, a splicing component 5 is further provided. The splicing component 5 may include a magnetic component 52 or a positioning post 51 disposed around the cabinet body 31. Based on this, when two adjacent display units 100 are spliced, they can be inserted and positioned by the positioning post 51 and then attracted by the magnetic component, which facilitates the splicing of the two display units 100 and makes the mechanical strength of the spliced ​​display screen 200 higher.

[0090] like Figures 1 to 18 As shown, a second aspect of the embodiments of this application provides a display screen 200, including a display unit 100 as described in any of the above technical solutions.

[0091] The display screen 200 provided in this application embodiment includes the display unit 100 of any of the above technical solutions. Therefore, the display screen 200 has all the beneficial effects of the display unit 100 of the above technical solutions, which will not be elaborated here.

[0092] It is understood that since the display unit 100 provided in this application embodiment can significantly reduce its thickness, the display screen 200 including the display unit 100 can also reduce its thickness.

[0093] like Figures 16 to 18 As shown, in one feasible implementation, there are multiple display units 100, and the multiple display units 100 are spliced ​​together.

[0094] In this technical solution, the display screen 200 may include multiple display units 100. The display screen 200 is formed by splicing multiple display units 100, which allows users to select the number of display units 100 based on actual needs to meet different size requirements, and is more conducive to the promotion of the display screen 200.

[0095] like Figure 14 and Figure 10 As shown, in one feasible embodiment, the display screen 200 further includes: an inter-module flexible circuit board 6, which is connected to the main control board 34 of the multiple display units 100; wherein, the inter-module flexible circuit board 6 includes multiple connecting lines of different lengths so that the multiple connecting lines are at different heights on the flexible circuit board 2, and the multiple connecting lines are used to connect to different display units 100; wherein, the inter-module flexible circuit board 6 is bonded to the housing body 31 of the display unit 100.

[0096] In this technical solution, when the display screen 200 includes multiple display modules, it may involve the collaborative control between these modules. Therefore, the display screen 200 can also include a flexible inter-module circuit board 6. This flexible inter-module circuit board 6 is connected to the main control board 34 of the multiple display units 100. Specifically, holes can be made in the housing body 31 of each display unit 100, and the flexible inter-module circuit board 6 passes through these holes, positioned between the housing body 31 and the main control board 34. The flexible inter-module circuit board 6 is connected to the main control board 34 of the multiple display units 100. By outputting control signals to different display units 100 through the flexible inter-module circuit board 6, the collaborative operation of the different display units 100 can be achieved. This enables interconnection and communication between back-mounted modules and the installation of power supply wires, allowing the removal of conventional housing sides. External circuitry can be used for network port hardware for signal interconnection and power supply lines, further meeting the requirement of reducing the overall assembly thickness. For the external circuitry of the display unit 100, the external circuitry can be part of the flexible circuit board 2.

[0097] In this technical solution, a style of inter-module flexible circuit board 6 is further provided. The inter-module flexible circuit board 6 includes multiple connecting lines of different lengths, which facilitates the connection of the inter-module flexible circuit board 6 with display units 100 at different locations, and facilitates communication between the inter-module flexible circuit board 6 and the display units 100.

[0098] like Figure 14 As shown, the inter-module flexible circuit board 6 includes five connecting lines, namely the first FPC line 61, the second FPC line 62, the third FPC line 63, the fourth FPC line 64, and the fifth FPC line 65, to connect to different display units 100.

[0099] In this technical solution, the flexible circuit board 6 between modules is bonded to the housing body 31 of the display unit 100, which can further reduce the thickness of the display screen 200.

[0100] like Figure 17 As shown, in one feasible embodiment, the display screen 200 further includes a control box 4, to which the housing assembly 3 of at least some of the multiple display units 100 is connected; wherein, the control box 4 includes a control box body 41, a control component, and a cover 42, the cover 42 being connected to the control box body 41; wherein, when the control box 4 is located at the edge of the display screen 200, both the cover 42 and the control box body 41 are connected to the housing assembly 3 of the display unit 100; when the control box 4 is located between two adjacent display units 100, only the control box body 41 is connected to the display assembly, so that the housing assemblies 3 of the two adjacent display units 100 are spliced ​​together.

[0101] In this technical solution, considering that the current technology uses a glass substrate IC die bonding and PI film peeling followed by film lamination to splice together a flexible screen, creating an ultra-thin screen with a certain degree of bending performance, the display screen 200 is not only costly, but also suffers from the serious problem of being unable to achieve infinite splicing of screens. This greatly limits the application of the display screen 200 in scenarios such as large-area displays and splicing display walls, severely restricting the product's applicability and market potential.

[0102] To address the technical problem of achieving unlimited splicing expansion of the screen, thus making it suitable for various large-scale splicing display scenarios such as large-area displays and splicing display walls, the display screen 200 provided in this application combines the technical solution of the display unit 100 mentioned above. In this technical solution, the display screen 200 may also include a control box 4, and the control box 4 may include a control box body 41, control components, and a cover 42.

[0103] When multiple display units 100 are spliced ​​together, two adjacent display units 100 can be positioned and connected by splicing parts 5. As for the control box 4, when the control box 4 is located at the edge of the display screen 200, the control box 4 will not occupy the splicing position of two adjacent display units 100. In this case, the cover 42 and the main body 41 of the control box are both connected to the cabinet assembly 3 of the display unit 100. On the one hand, this makes the fixation of the control box 4 more reliable. On the other hand, the cover 42 can occupy space on the cabinet body 31, making the display unit 100 more aesthetically pleasing. However, when the control box 4 is located between two adjacent display units 100, the control box 4 may affect the seamless splicing of the two adjacent display units 100. In this case, the cover 42 of the control box 4 can be removed, and the main body 41 of the control box can be directly connected to the display assembly without the need to assemble the cover 42 again. This allows the control box 4 to make way for the splicing of the two adjacent display units 100, thereby achieving seamless splicing of the two display units 100 and enabling the infinite expansion of the display screen 200.
