Description

Technical Field

[0001] The utility model relates to a display device, in particular to a spherical screen display device. Background Art

[0002] A dome display is a special form of display device, usually composed of many display modules, showing a spherical or hemispherical appearance. Dome displays are usually used in indoor or outdoor stage performances, concerts, sports events and other occasions, with unique visual effects and viewing pleasure. Dome displays can achieve a full range of display effects, allowing viewers to see clear images from any angle.

[0003] Existing ball screen display devices are usually assembled from multiple display modules, which are assembled into display screens of different shapes and sizes as needed to adapt to different places and application requirements. Common ball screen display devices are mostly composed of several plane or curved structures of the same or different shapes and sizes, but it is often difficult to use a small number of display modules to assemble a ball screen display device with high structural stability, which leads to complex production processes, high costs, and weak structural stability due to the large number of display modules required.

[0004] Therefore, a spherical screen display device is needed to solve the problem that the spherical screen display device in the prior art is difficult to take into account both using a smaller number and types of display modules to simplify the production process and reduce costs, and making the spherical screen display device have higher structural stability. Utility Model Content

[0005] In view of the shortcomings of the prior art mentioned above, the technical problem to be solved by the present invention is to provide a spherical screen display device, which is used to solve the problem that the spherical screen display device in the prior art is difficult to take into account both the use of a smaller number and types of display modules to simplify the production process and reduce costs, and the spherical screen display device having higher structural stability.

[0006] In order to achieve the above object, the utility model provides a ball screen display device, comprising:

[0007] A plurality of display modules, wherein the display modules include a display chassis and a plurality of display units laid on the display chassis, the display chassis is a triangular frame structure, the outer contour of the spherical screen display device is formed by combining and splicing a plurality of display chassis with completely identical sizes and shapes at a certain angle, the display unit is a triangular sheet structure, a plurality of display units with completely identical sizes and shapes are laid on one side of the display chassis, and the display units on the plurality of display chassis together constitute the display screen of the spherical screen display device.

[0008] In an embodiment of the present invention, a plurality of fixing and adjusting members are disposed on the display unit, and the display unit is placed on the display chassis through the fixing and adjusting members.

[0009] In one embodiment of the present invention, the distance between each display unit and the display chassis is controlled by the fixed adjustment member, and the inclination angle between each display unit and the display chassis is adjusted, thereby making the curvature of the display screen of the spherical screen display device smoother.

[0010] In an embodiment of the present invention, the fixing adjustment member is arranged on the display chassis by a fastening connection.

[0011] In an embodiment of the present invention, the fixing and adjusting member is placed on the chassis by magnetic attraction.

[0012] In one embodiment of the utility model, a plurality of heat dissipation holes are provided on the circuit substrate. Since the spherical screen display device will generate a certain amount of heat during operation, heat dissipation is an important issue. A good heat dissipation design can reduce the failure rate of the spherical screen display screen due to poor heat dissipation, and ensure the stability and long-term reliability of use. There are many heat dissipation methods for existing spherical screen display devices, such as using fans for heat dissipation, using heat dissipation fins for heat dissipation, or selecting high thermal conductivity materials for heat dissipation, etc. Although these methods can achieve a certain heat dissipation effect, the cost is often high. The utility model provides a method of setting a certain number and area of ​​heat dissipation holes on the LED.

[0013] In an embodiment of the present invention, a plurality of mounting brackets are provided on the other side of the display chassis where the display unit is laid, and the plurality of display chassis are connected via the mounting brackets.

[0014] In one embodiment of the present invention, the display chassis is a triangular plane structure and the display unit is a triangular plane structure. Relatively speaking, arc-shaped modules require more complex processes and technologies in terms of curved surface design, mold manufacturing, lamp bead installation, etc., and have higher manufacturing costs; while the process and technology requirements for manufacturing flat display modules are lower, and the manufacturing cost is reduced.

[0015] In one embodiment of the utility model, the display chassis has a triangular arc surface structure and the display unit has a triangular arc surface structure. Compared with a spherical screen display device composed of a display chassis with a triangular plane structure and a display unit with a triangular plane structure, the spherical screen display device composed of a curved display chassis and a display unit has a smoother screen curve and a better display effect.

[0016] In an embodiment of the present invention, the spherical screen display device further includes a reinforcement frame, and the reinforcement frame is used to reinforce the spherical screen display device.

[0017] In an embodiment of the present invention, a base is disposed on the ground, and the base and the reinforcement frame are disposed on the base.

[0018] As described above, the spherical screen display device involved in the utility model has the following beneficial effects: when assembling the spherical screen display device of the utility model, a plurality of display units with completely identical sizes and shapes are laid on one side of the display chassis through the fixed adjustment member, thereby completing the combination of a single display module; then, a plurality of display chassis with completely identical sizes and shapes corresponding to the plurality of display modules are combined and spliced ​​at a certain angle to form the outer contour of the spherical screen display device, so that all the display units laid on the plurality of display chassis together constitute the display screen of the spherical screen display device; since the size and shape of the display chassis and the display unit used are completely consistent, the types of parts required for assembling the spherical screen display device are greatly reduced; at the same time, the display chassis and the display unit both adopt a triangular structure, and a limited number of triangular structures can better fit the spherical surface of the entire spherical screen display device and maintain a uniform distribution on the spherical surface; finally, since the triangle has stability, the display chassis and the display unit using a triangular structure can ensure that the spherical screen display device is more stable, and when impacted by external force, the triangular structure can disperse the external force in time, thereby achieving the effect of protecting the overall structure.

[0019] In summary, the spherical screen display device involved in the utility model is assembled through a number of triangular structures with completely identical sizes and shapes, which reduces the number and types of parts required for assembly, enhances structural stability, and solves the problem that the spherical screen display device in the prior art is difficult to take into account both the use of a smaller number and types of display modules to simplify the production process and reduce costs, and the spherical screen display device having higher structural stability.

[0047] like Figure 1As shown, the utility model provides a ball screen display device, comprising:

[0048] A plurality of display modules 1, wherein the display modules 1 include a display chassis 11 and a plurality of display units 12 laid on the display chassis 11, wherein the display chassis 11 is a triangular frame structure, and the outer contour of the spherical screen display device is formed by combining and splicing a plurality of display chassis 11 with completely identical sizes and shapes at a certain angle, and the display unit 12 is a triangular sheet structure, and a plurality of display units 12 with completely identical sizes and shapes are laid on one side of the display chassis 11, and the display units 12 on the plurality of display chassis 11 together constitute the display screen of the spherical screen display device.

[0049] In order to better introduce the spherical screen display device of the utility model, the following specific applications are now described: Figure 5 As shown, when assembling the ball screen display device of the utility model, a plurality of display units 12 with completely identical sizes and shapes are laid on one side of the display case 11 through the fixed adjustment member 123, thereby completing the combination of a single display module 1; then, a plurality of display cases 11 with completely identical sizes and shapes corresponding to the plurality of display modules 1 are combined and spliced ​​at a certain angle to form the outer contour of the ball screen display device, so that all the display units 12 laid on the plurality of display cases 11 together constitute the display screen of the ball screen display device; since the size and shape of the display cases 11 and the display units 12 used are completely identical, the types of parts required for assembling the ball screen display device are greatly reduced; at the same time, the display cases 11 and the display units 12 both adopt a triangular structure, and a limited number of triangular structures can better fit the spherical surface of the entire ball screen display device and maintain a uniform distribution on the spherical surface; finally, since the triangle has stability, the display cases 11 and the display units 12 with a triangular structure can ensure that the ball screen display device is more stable, and when impacted by external force, the triangular structure can disperse the external force in time, thereby achieving the effect of protecting the overall structure.

[0050] In this embodiment, if Figure 5 as well as Figure 6As shown, the display unit 12 includes a circuit substrate 121 and light-emitting elements 122 evenly arranged on the circuit substrate 121; further, in this embodiment, the light-emitting elements 122 use LED lamp beads, which have the characteristics of high efficiency, long life, fast start-up, environmental protection, adjustable color temperature, shock and vibration resistance, etc. compared with other light-emitting elements. High efficiency means that the LED lamp beads have a high photoelectric conversion efficiency and can convert electrical energy into light energy without generating too much heat. Compared with traditional light sources, LED lamp beads can produce the same or brighter light with lower energy consumption; long life means that the LED lamp beads have a longer service life, usually up to tens of thousands of hours or even longer. This means that the LED lamp beads are more durable, reducing the frequency of replacing bulbs and maintenance costs; fast start-up means that the LED lamp beads can immediately reach full light output without preheating time. This makes the LED lamp beads more convenient and energy-saving in situations where frequent switching is required; environmental protection means that the LED lamp beads do not contain harmful substances such as mercury, and have lower energy consumption, reducing the negative impact on the environment. At the same time, the long life of LED lamp beads also reduces the generation of electronic waste; adjustable color temperature means that LED lamp beads can achieve different color temperatures and color performances through different luminous materials and designs, from warm light to cold light, to meet the lighting effects of different environments and needs; shock and vibration resistance means that LED lamp beads are made of solid materials, without fragile filaments or glass shells, so they have strong shock and vibration resistance and are suitable for various harsh environments. Furthermore, LED lamp beads can be selected

[0053] In one embodiment of the present invention, the fixed adjustment member 123 is used to control the distance between each display unit 12 and the display chassis 11, and adjust the inclination angle between each display unit 12 and the display chassis 11, thereby making the curvature of the display screen of the spherical screen display device smoother.

[0056] In one embodiment of the present invention, Figure 5 as well as Figure 7 As shown, the circuit substrate 121 is provided with a number of heat dissipation holes 121a. Because the ball screen display device will generate a certain amount of heat during operation, heat dissipation is an important issue. A good heat dissipation design can reduce the failure rate of the ball screen display screen caused by poor heat dissipation, and ensure the stability and long-term reliability of use. There are many heat dissipation methods for existing ball screen display devices, such as using fans to dissipate heat, using heat dissipation fins to dissipate heat, or selecting high thermal conductivity materials for heat dissipation, etc. Although these methods can achieve a certain heat dissipation effect, the cost is often high. The utility model provides a method of setting a certain number and area of ​​heat dissipation holes 121a on the LED; further, in this embodiment, the heat dissipation holes 121a are evenly opened on the circuit substrate 121; further, in this embodiment, the LED lamp beads use smaller Micro-LED lamp beads, so that the total area of ​​the heat dissipation holes 121a is 10% to 60% of the area of ​​a single display unit 12, further increasing the heat dissipation capacity.

[0058] In one embodiment of the present invention, Figure 2 as well as Figure 3 As shown, the display chassis 11 is a triangular plane structure and the display unit 12 is a triangular plane structure. Relatively speaking, the arc-shaped module requires more complex processes and technologies in terms of curved surface design, mold manufacturing, and lamp bead installation, and has a higher manufacturing cost; while the process and technology requirements for manufacturing flat display modules are lower, and the manufacturing cost is reduced.

[0059] In one embodiment of the present invention, the display chassis 11 is a triangular arc surface structure and the display unit 12 is a triangular arc surface structure (not shown). Compared with a spherical screen display device composed of a display chassis 11 with a triangular plane structure and a display unit 12 with the same triangular plane structure, the spherical screen display device composed of a curved display chassis 11 and a display unit 12 has a smoother screen curve and a better display effect.
