[0002] Currently, considerable research has been invested in 3D / stereoscopic displays both domestically and internationally, and many products meet functional requirements. This significantly increases the interactivity of information display and enhances the user experience. Suspended display technology is another functional display method developed in recent years. It can display images in the air without a medium, creating a realistic effect by combining virtual floating images with the displayed scenery, thereby enhancing the visual experience.

[0003] However, due to the size limitations of the floating display screen and the fact that spliced ​​displays are affected by the width of the border, floating displays can currently only be used in small-scale applications. Summary of the Invention

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] The following disclosure provides many different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0042] Please refer toFigure 1 This invention provides a display device comprising at least two display modules. Each display module includes a display panel and a floating display generating device. The floating display generating device is disposed on the light-emitting side of the display panel and is used to form a floating display image on the side of the floating display generating device away from the display panel. The floating display image and the display panel are symmetrically arranged with respect to the floating display generating device.

[0043] Specifically, the two floating display generating devices of two adjacent display modules are not parallel and are spaced apart to form a fan-shaped gap 101 between the two adjacent display modules. At least two display modules include an adjacent first display module 10 and a second display module 20. The first floating display screen 13 corresponding to the first display module 10 is connected to the second floating display screen 23 corresponding to the second display module 20. The connection point between the first floating display screen 13 and the second floating display screen 23 is located at the vertex of the corner of the fan-shaped gap 101. The end of the first floating display generating device 12 of the first display module 10 near the second display module 20 is located on one side of the fan-shaped gap 101. The end of the second floating display generating device 22 of the second display module 20 near the first display module 10 is located on the other side of the fan-shaped gap 101. The first display panel 11 of the first display module 10 near the first border 111 of the second display module 20 and the second display panel 21 of the second display module 20 near the second border 211 of the first display module 10 are both located within the fan-shaped gap 101.

[0044] In the implementation process, the display device provided by the present invention includes at least two display modules, and the two display modules can achieve floating display through a floating display generating device. In addition, between the adjacent first display module 10 and second display module 20, the first border 111 of the first display panel 11 and the second border 211 of the second display panel 21 are both located within the fan-shaped gap 101, and the first floating display screen 13 and the second floating display screen 23 are connected. Thus, the borders between the two adjacent display panels can be accommodated within the fan-shaped gap 101, so that the two adjacent floating display screens can be spliced ​​together. This allows the display device provided by the embodiment of the present invention to simultaneously achieve floating display and seamless display, and can achieve large-size spliced ​​floating display.

[0045] Specifically, in one embodiment of the present invention, please continue to refer to... Figure 1 The display device provided in this embodiment of the invention includes at least two display modules, and two adjacent display modules are spliced ​​together to achieve a large-size display.

[0046] Each display module includes a display panel and a floating display generating device located on the light-emitting side of the display panel. The floating display generating device is used to generate a floating display image on the side of the floating display generating device away from the display panel. The floating display image and the display panel are symmetrically arranged with respect to the floating display generating device.

[0047] like Figure 2 As shown, the floating display generating device may include a first reflective layer and a second reflective layer stacked together. The first reflective layer includes a plurality of first reflective structures 201 extending in the same direction, and the second reflective layer includes a plurality of second reflective structures 202 extending in the same direction. The extending directions of the first reflective structures 201 and the second reflective structures 202 are perpendicular to each other. Furthermore, after being reflected twice by the first reflective structures 201 and the second reflective structures 202, light emitted from the display panel can form a floating display image on the side of the floating display generating device away from the display panel. The floating display image and the display panel are symmetrically arranged relative to the floating display generating device, for example, in... Figure 1 In the cross-sectional view shown, the display panel and the floating display screen are arranged symmetrically with respect to the floating display generating device.

[0048] It should be noted that the embodiments of the present invention only provide a structure for a floating display generating device, but are not limited thereto. The floating display generating device can also be replaced with other devices that can realize floating displays.

[0049] Furthermore, multiple display modules are arranged along a preset direction X, and the floating display screen formed by the multiple display modules can be connected together along the preset direction X to form a seamless spliced ​​large-size floating display screen.

[0050] While all display modules share the same structure, their placement and the arrangement of the floating display generating devices and display panels within each module differ. Specifically, the two floating display generating devices in adjacent display modules are not arranged parallel to each other and are spaced apart, thus creating a fan-shaped gap 101 between adjacent display modules. Figure 1 As shown.

[0051] In this embodiment of the invention, the plurality of display modules include a first display module 10, a second display module 20, and a third display module 30; and the first display module 10, the second display module 20, and the third display module 30 are arranged sequentially along a preset direction.

[0052] It is understood that the embodiments of the present invention are described using multiple display modules including a first display module 10, a second display module 20 and a third display module 30 as an example. In other embodiments of the present invention, the display module may also include two display modules, four display modules or more display modules; and the above different numbers of display modules are all arranged along a preset direction X.

[0053] Specifically, please continue to refer to Figure 1 The first display module 10 includes a first display panel 11 and a first floating display generating device 12 disposed on the light-emitting side of the first display panel 11. The first floating display generating device 12 is used to form a first floating display image 13 on the side of the first floating display generating device 12 away from the first display panel 11. The first floating display image 13 and the first display panel 11 are symmetrically arranged with respect to the first floating display generating device 12. The second display module 20 includes a second display panel 21 and a second floating display generating device 22 disposed on the light-emitting side of the second display panel 21. The second floating display generating device 22 is used to form a first floating display image 13 on the side of the first floating display generating device 12 away from the first display panel 11. The second floating display image 23 is formed on the side of the device 22 away from the second display panel 21. The second floating display image 23 and the second display panel 21 are symmetrically arranged with respect to the second floating display generating device 22. The third display module 30 includes a third display panel 31 and a third floating display generating device 32 disposed on the light-emitting side of the third display panel 31. The third floating display generating device 32 is used to form a third floating display image 33 on the side of the third floating display generating device 32 away from the third display panel 31. The third floating display image 33 and the third display panel 31 are symmetrically arranged with respect to the third floating display generating device 32.

[0054] The first floating display generating device 12 is arranged along the first direction X1, the second floating display generating device 22 is arranged along the second direction X2, and the third floating display generating device 32 is arranged along the third direction X3. The first direction X1, the second direction X2, and the third direction X3 are not parallel to each other, and the first direction X1 has a first angle with the preset direction X, the second direction X2 has a second angle with the preset direction X, and the third direction X3 has a third angle with the preset direction X; and the first angle is greater than the second angle, and the second angle is greater than the third angle.

[0055] The first display panel 11 includes a first frame 111 near the second display module 20, and the second display panel 21 includes a second frame 211 near the second display module 20. The first frame 111 and the second frame 211 are both located within the fan-shaped gap 101 between the first display module 10 and the second display module 20, and neither the first frame 111 nor the second frame 211 exceeds the boundary of the fan-shaped gap 101. Furthermore, the first frame 111 and the second frame 211 are staggered, that is, the first frame 111 is located on the side of the second frame 211 away from the first floating display generating device 12 and the second floating display generating device 22, and the distance between the side of the first frame 111 away from the second frame 211 and the side of the second frame 211 away from the first frame 111 is greater than or equal to the sum of the thicknesses of the first frame 111 and the second frame 211.

[0056] Similarly, the second display panel 21 includes a third frame 212 near the side of the third display module 30, and the third display panel 31 includes a fourth frame 311 near the side of the second display panel 21. The third frame 212 and the fourth frame 311 are both located within the fan-shaped gap 101 between the second display module 20 and the third display module 30, and neither the third frame 212 nor the fourth frame 311 exceeds the boundary of the fan-shaped gap 101. Furthermore, the third frame 212 and the fourth frame 311 are staggered, that is, the third frame 212 is located on the side of the fourth frame 311 away from the second floating display generating device 22 and the third floating display generating device 32, and the distance between the side of the third frame 212 away from the fourth frame 311 and the side of the fourth frame 311 away from the third frame 212 is greater than or equal to the sum of the thicknesses of the third frame 212 and the fourth frame 311.

[0057] Continuing from the above, the first floating display screen 13, the second floating display screen 23, and the third floating display screen 33 are connected together along the preset direction X and are coplanar, all located in the preset plane.

[0058] In other embodiments of the present invention, one or more other display modules located on the side of the third display module 30 away from the second display module 20 can be arranged in the manner described above, and the angle between the arrangement direction of the floating display devices and the preset direction X gradually decreases along the direction away from the first display module 10. This forms a large-size floating splicing display screen in the preset direction X, and can eliminate the seams between adjacent floating display screens, improving the display effect.

[0059] In this embodiment of the invention, the distance between the borders of adjacent display panels needs to be designed to achieve the above arrangement, such as the distance between the side of the first border 111 away from the second border 211 and the side of the second border 211 away from the first border 111, and the distance between the side of the third border 212 away from the fourth border 311 and the side of the fourth border 311 away from the third border 212.

[0060] Please combine Figure 1 and Figure 3 In each display module, the length and thickness of the display panel are equal, meaning the length of the floating display screen along the preset direction X is equal. The angle between the arrangement directions of the two floating display devices in any two adjacent display modules is equal. The angle between the first direction X1 and the preset direction X is α, and the angle between the first direction X1 and the second direction X2, as well as the angle between the second direction X2 and the third direction X3, are all θ. The vertical distance from the connection point of the first floating display screen 13 and the second floating display screen 23 to the first floating display generating device 12 is H1, the vertical distance from the connection point of the second floating display screen 23 and the third floating display screen 33 to the second floating display generating device 22 is H2, and the vertical distance from the connection point of the third floating display screen 33 and the floating display screen corresponding to an adjacent display module to the third floating display generating device 32 is H3.

[0061] The angle between the second direction X2 and the preset direction X is α-θ, and the angle between the third direction X3 and the preset direction X is α-2θ.

[0062] It should be noted that in multiple display modules, along the preset direction X, the angle between the multiple floating display generating devices and the preset direction X becomes smaller and smaller, and the angle that decreases each time is θ. That is, the angle between the arrangement directions of the two floating display devices in any two adjacent display modules is θ.

[0063] Furthermore, taking the first display module 10 as an example, the length of line segment AD is set as a1, and the length of selected segment CF is M1. That is, it is necessary to satisfy that the length of the first border 111 of the first display module 10 is less than or equal to a1, and the sum of the thicknesses of the first border 111 and the second border 211 is less than or equal to M1, so that the first border 111 can be accommodated in the fan-shaped gap 101.

[0064] Understandably, other display modules also correspond to two sizes, 'a' and 'M', and the smallest 'a' is selected from multiple 'a' and multiple 'M' sizes. min and M min And make the length of the display panel bezel less than a min The thickness of the display panel is less than twice that of M. minThis allows multiple display modules to be arranged in the manner described above.

[0065] Specifically, please continue to combine Figure 1 and Figure 3 In the first display module 10, line segment BE is perpendicular to line segment AO, and line segment BD is perpendicular to both line segments GO and IJ. Therefore, ∠DBE equals ∠AJI, which means ∠DBE equals α. Thus, ∠ABE equals α + θ, and ∠BAO equals 90° - (α + θ). According to the following trigonometric formulas:

[0066]

[0067] It can be obtained In this context, α, θ, L, and H1 are all known parameters, and α and θ are both greater than 0 and less than 90°. α is the angle between the arrangement direction of the floating display generating device in the first display module arranged along the preset direction X and the preset direction X. θ is the angle between the arrangement directions of two adjacent floating display generating devices. L is the length of the floating display screen along the preset direction X, i.e., the length of the display panel. Thus, the value of a1 can be obtained.

[0068] Similarly, referring to the above calculation process, we can obtain the following in the second display module 20:

[0069]

[0070]

[0071] In the third display module 30, the following can be obtained:

[0072]

[0073]

[0074] That is, for the nth display module arranged along the preset direction X:

[0075]

[0076]

[0077] Furthermore, in the first display module 10, in △ABD, the length of line segment BD is 2H1, ∠BAO equals 90° - (α + θ), and ∠BDA equals 90° - (α + 2θ). Then, according to the following trigonometric formulas:

[0078]

[0079] The length of line segment AB can be obtained.

[0080] Furthermore, ∠BOF equals 2(α-θ), ∠EBO equals 90°-2α, then ∠ABO equals 90-(α-θ), and ∠BFO equals 90-(α-θ). Similarly, in △BOF, according to the following trigonometric formulas:

[0081]

[0082] The length of line segment BF can be obtained, and the length of line segment AF can be obtained by subtracting the length of line segment BF from the length of line segment AB.

[0083] Then, in △ACF, the following trigonometric formulas apply:

[0084]

[0085] The length of line segment CF can be obtained, which is the length of M1.

[0086]

[0087] That is, for the nth display module arranged along the preset direction X:

[0088]

[0089] Therefore, the smallest a can be selected from multiple a's and multiple M's. min and M min And make the length of the display panel bezel less than a min The thickness of the display panel is less than twice that of M. min This allows multiple display modules to be arranged in the manner described above.

[0090] It should be noted that in the above embodiment, the calculation is based on the first display module 10 being the first display module arranged along the preset direction X. Similarly, when the first display module 10 is the nth display module arranged along the preset direction X, and the second display module 20 is the (n+1)th display module arranged along the preset direction X, where n is a positive integer greater than or equal to 1, the first display module 10 and the second display module 20 can also be calculated according to a. n and M n The formula is used for calculation.

[0091] In summary, the display device provided by the present invention includes at least two display modules, and the two display modules can achieve floating display through a floating display generating device. In addition, between the adjacent first display module 10 and second display module 20, the first border 111 of the first display panel 11 and the second border 211 of the second display panel 21 are both located within the fan-shaped gap 101, and the first floating display screen 13 and the second floating display screen 23 are connected. Thus, the borders between the two adjacent display panels can be accommodated within the fan-shaped gap 101, so that the two adjacent floating display screens can be spliced ​​together. This allows the display device provided by the embodiment of the present invention to simultaneously achieve floating display and seamless display, and can achieve large-size spliced ​​floating display.

[0092] Furthermore, in another embodiment of the present invention, the difference from the previous embodiment is that the multiple display modules are arranged in an array along the horizontal and vertical directions in a preset plane.

[0093] Specifically, please refer to Figure 4 as well as Figure 5 The diagram shows only a cross-sectional structure arranged along one of the directions. The first floating display generating device 12 is arranged along the first direction X1, which is parallel to the preset direction X. That is, the first floating display generating device 12, the first display panel 11, and the first floating display screen 13 are all parallel. The second floating display generating device 22 is arranged along the second direction X2, and the third floating display generating device 32 is arranged along the third direction X3.

[0094] The display device includes four second display modules 20, with each pair of second display modules 20 arranged symmetrically relative to the first display module 10.

[0095] In addition, the display device also includes four third display modules 30, with each pair of third display modules 30 symmetrically distributed relative to the first display module 10, and the third display modules 30 located on the side of the second display module 20 away from the first display module 10.

[0096] It should be noted that the embodiments of the present invention are described using a cross-sectional structure of multiple display modules arranged along a preset direction X as an example, and the arrangement perpendicular to the preset direction X can be used as a reference.
