Referring to fig. 1 and fig. 2, fig. 1 is a first structural schematic diagram of an arc display device according to an embodiment of the present disclosure. Fig. 2 is a schematic structural diagram of an arc display device according to an embodiment of the present disclosure. The arc-shaped display device 100 provided by the embodiment of the application comprises a shell 101 and a plurality of display modules 102. The housing 101 includes at least a partially cambered surface structure, and the housing 101 has magnetism. The cambered surface structure extends into a spherical shape, and the housing 101 has a first surface 101a and a second surface 101b which are oppositely arranged. The first surface 101a is a surface close to the center of the sphere, and a plurality of display modules 102 are spliced on the housing 101. The display module 102 is magnetically connected to the housing 101.

The arc display device 100 may be a spherical display screen for exhibition and publicity, or may be a display screen of a dome cinema. The arc display device 100 can be manufactured according to the production requirement, and the radius of the sphere formed by extending the housing 101 is designed.
The arc display device 100 that this application embodiment provided has simplified the step of assembling and the degree of difficulty of assembling of display module assembly 102 with casing 101 through being connected display module assembly 102 with casing 101 magnetism, assembles the process simply to convenient dismantlement is maintained.
Among other things, the case 101 may form an outer contour of the arc display device 100. In some embodiments, the housing 101 may include a middle frame and a back cover (not shown in the figures) that combine with each other to form the housing 101. The middle frame and the rear cover may form a receiving space for receiving devices such as the display module 102, a circuit board, and a battery, which are well known to those skilled in the art and will not be described in detail herein, but are not shown in the drawings.
Alternatively, the housing 101 may be a metal housing, such as a metal such as magnesium alloy, stainless steel, etc. It should be noted that the material of the housing 101 according to the embodiment of the present application is not limited thereto, and other materials may be used. Such as: the housing 101 may be a plastic housing or a ceramic housing. Alternatively, the housing 101 may be a metal and plastic casing structure. Specifically, the metal part may be formed first, for example, a magnesium alloy substrate is formed by injection molding, and then plastic is injected on the magnesium alloy substrate to form a plastic substrate, so as to form the complete casing 101 structure. The material and process of the housing 101 are not limited to these. For example, the housing 101 may be a glass housing.
Wherein the circuit board is mounted in the housing 101. The circuit board may be a main board of the arc display device 100, and one, two or more functional components of a motor, a microphone, a speaker, an earphone interface, a usb interface, a distance sensor, an ambient light sensor, a receiver, and a processor may be integrated on the circuit board.
The display module 102 may be one of a Light-Emitting Diode (LED) display module, a Micro LED display module, and a sub-millimeter LED display module. Furthermore, the display module adopts a Micro LED or a Mini LED for luminous display. Micro LEDs, Mini LEDs are small-sized light emitting diodes. And, by improving the process and the panel design, Micro LEDs and Mini LEDs with smaller pitches can be manufactured. After the distances between the light emitting diodes of the Micro LED display module and the Mini LED display module are reduced, on one hand, the display with higher resolution can be realized, and the display effect is enhanced; on the other hand, the effect of no boundary can be visually achieved, and picture fusion is better performed with the adjacent display module 102, so that the display picture is more continuous and complete.
Optionally, please refer to fig. 1. A plurality of display modules 102 are arranged on the first surface 101a, and the radius of the sphere is R1. Wherein R is1Greater than or equal to 50 meters. In particular, R1The value of (c) may be 50 meters, 51 meters, 52 meters, 53 meters, 54 meters, 55 meters, 60 meters, 70 meters, 80 meters, 90 meters, or 100 meters. The first surface 101a is a side of the arc display device 100 close to the center of the sphere, i.e., the display module 102 is disposed on an inner side of the arc display device 100. Specifically, the arc display device 100 may be applied to a spherical display cinema or a spherical screen cinema instead of a projector to enhance the display effect. At this time, the arc display device 100 may be a part of an arc surface in a sphere. Due to R1The numerical value of (2) is larger, the formed arc surface is smoother, the size of the display module 102 can be properly enlarged, the assembling difficulty can be reduced, and the assembling time can be shortened. Moreover, the process can be simplified when the display module 102 is manufacturedAnd the process difficulty is reduced.
It should be understood that for R1The description of numerical values in the form of a range is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the invention. Accordingly, the described range descriptions should be considered to have specifically disclosed all the possible sub-ranges as well as individual numerical values within that range. For example, it is contemplated that the description of a range above 50 meters has specifically disclosed sub-ranges such as from 50 meters to 55 meters, from 50 meters to 60 meters, from 60 meters to 100 meters, from 50 meters to 52.6 meters, etc., as well as single numbers within the range, such as 51, 52, 53, 54, 55, and 56, etc., regardless of the range. In addition, whenever a numerical range is indicated herein, it is meant to include any number (fractional or integer) recited within the indicated range. The other numerical ranges in the present application are also not described in detail below.
Optionally, please refer to fig. 2. A plurality of display modules 102 are arranged on the second surface 101b, and the radius of the sphere is R2. Wherein R is2Greater than or equal to 50 centimeters. In particular, R2May be 50 cm, 55 cm, 60 cm, 65 cm, 70 cm, 75 cm, 80 cm, 85 cm, 90 cm, 95 cm or 100 cm. The second surface 101b is disposed opposite to the first surface, and the second surface 101b is a side of the arc display device away from the center of the sphere. That is, the display module 102 is disposed on an outer surface of the arc display device 100. Specifically, the arc display device 100 may be applied to a ball display, which is used for a commercial advertisement and an exhibition. At this time, the arc display device 100 is a whole sphere. Due to R2The numerical value of (2) is small, the size of the display module 102 can be properly reduced according to the flatness of the spherical surface, so that the assembly of the display module 102 is tighter, and the integrity of the display picture is guaranteed.
Optionally, the display module 102 is shaped like a regular hexagon. In the related art, a square or quadrilateral display module 102 is often used to display a spherical or arc surface in an assembled manner. The display is affected by the unevenness of the surface of the cambered surface or the spherical surface, so that the tight splicing is difficult to realize, and the splicing seam is often generated to affect the display. The display module 102 of the embodiment of the present application is a regular hexagon. When the curvature radius is large enough, the regular hexagonal display module 102 can form a tight splice on the arc surface. Wherein the side length of the regular hexagon is 10 cm to 20 cm. Specifically, the side length of the regular hexagon may be 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 15 cm, 16 cm, 17 cm, 18 cm, 19 cm, or 20 cm.
In connection with the above, the size of the display module 102 can be considered according to the curvature radius of the housing 101 to be assembled. For example, when the arc display device 100 is used as a spherical display theater, the arc of the arc display device 100 has a larger radius of sphere, and the display module 102 with a larger size can be used for assembly. Optionally, a 20 cm-side regular hexagon display module 102 is assembled on the housing 101. When the display module 102 of the arc-shaped display device 100 is assembled on the outer side as a spherical display, the display module 102 with a small size can be used for assembly. It should be noted that, the display module 102 provided in the embodiment of the present application can be adaptively designed according to the arc-shaped display device 100, and the above-mentioned example is not intended to limit the present application. The small-sized display module 102 assembled on the casing 101 with the gentle arc surface can also increase the resolution of the arc-shaped display device 100, so that the display picture is better.
Optionally, please refer to fig. 3, where fig. 3 is a first structural schematic diagram of a display module in an arc display device according to an embodiment of the present application.

The substrate 1021 has magnetism, and the display module 102 is magnetically connected with the casing 101 through the substrate 1021.
Optionally, please refer to fig. 4, where fig. 4 is a schematic structural diagram of an array module in an arc display device according to an embodiment of the present disclosure. The array module 1022 includes a light-shielding layer 1 disposed on the substrate, a buffer layer 2 disposed on the substrate and covering the light-shielding layer 1, an active layer 3, a gate insulating layer 4, and a gate electrode layer 5 stacked on the buffer layer 2 in sequence from bottom to top, and an interlayer dielectric layer 6 located above the buffer layer 2 and covering the active layer 3, the gate insulating layer 4, and the gate electrode layer 5. And the source electrode 7 and the drain electrode 8 are positioned on the interlayer dielectric layer 6, and the source electrode 7 and the drain electrode 8 are respectively electrically connected with the active layer 3. The source electrode 7 and the drain electrode 8 are also covered with a planarization layer 9. The array module 1022 may also include other structures, and the structure of the array module 1022 and the specific arrangement thereof are commonly used in the art and will not be described herein.
Note that the structure of the thin film transistor formed in the array module 1022 is not limited in this application, and the thin film transistor may be a top gate thin film transistor, a bottom gate thin film transistor, a double gate thin film transistor, or a single gate thin film transistor. The detailed structure of the thin film transistor is not described in detail in the present application. Alternatively, the thin film transistor type of the array module 1022 in the present application may be a top gate type. The Top gate (Top gate) thin film transistor has lower parasitic capacitance and better ductility due to no overlap between the source electrode 7, the drain electrode 8 and the gate electrode layer 5, and can reduce delay in signal transmission. Meanwhile, the self-aligned preparation method is adopted, so that the preparation of a short-channel device is facilitated, and the device characteristics are improved.
Specifically, the active layer 3 may be made of a material including any one of Indium Gallium Zinc Oxide (IGZO), Indium Zinc Tin Oxide (IZTO), Indium Gallium Zinc Tin Oxide (IGZTO), Indium Tin Oxide (ITO), Indium Zinc Oxide (IZO), Indium Aluminum Zinc Oxide (IAZO), Indium Gallium Tin Oxide (IGTO), or Antimony Tin Oxide (ATO). The materials have good conductivity and transparency, and are small in thickness, so that the whole thickness of the display panel cannot be influenced. Meanwhile, the electronic radiation and ultraviolet and infrared light which are harmful to human bodies can be reduced.
Optionally, please refer to fig. 5, where fig. 5 is a second structural schematic diagram of a display module in an arc display device according to an embodiment of the present application.

For example, a side printing base station is used to print silver paste, and the traces 12 are formed by curing the silver paste to connect the control chip 11.
In some embodiments, the routing layer is formed on the side of the substrate 1021 by physical vapor deposition or magnetron sputtering. The wiring layer manufactured by the method can ensure that the wiring layer and the side surface of the substrate form compact and strong bonding force. The wiring layer is not easy to separate from the substrate, and has high reliability and high reliability. Traces 12 can then be formed by laser routing layers. The laser lithography makes the routing layer into a routing 12, and the width of the formed routing 12 is controllable.
Traces 12 are disposed on the side of the substrate 1021 and are connected to a control chip 11 behind the substrate 1021.
