Referring to fig. 1, embodiments of the present disclosure provide a display device 100, the display device 100 may be any device that displays whether in motion (e.g., video) or stationary (e.g., still images), and whether textual or pictorial. More particularly, it is contemplated that the embodiments may be implemented in or associated with a variety of electronic devices such as, but not limited to, mobile telephones, wireless devices, personal data assistants, hand-held or portable computers, global positioning system receivers/navigators, cameras, video players, camcorders, game consoles, wrist watches, clocks, calculators, television monitors, flat panel displays, computer monitors, auto displays (e.g., odometer display, etc.), navigators, cockpit controls and/or displays, displays of camera views (e.g., of a rear view camera in a vehicle), electronic photographs, electronic billboards or signs, projectors, architectural structures, packaging, and aesthetic structures (e.g., a display of an image for a piece of jewelry), and so forth. Illustratively, the display device 100 is an LED all-in-one machine.

In some embodiments, referring to fig. 1, the display device 100 includes a display screen 1, and the display screen 1 is used for displaying pictures.

As shown in fig. 2, the display panel 1 includes a circuit board 11 and a light emitting device 12 disposed on the circuit board 11.

Illustratively, the Circuit Board 11 is a Printed Circuit Board (PCB). The light emitting device 12 is connected to the printed circuit board by printed wiring.

It should be noted that the Light Emitting device 12 may include one or more of Micro Light Emitting Diode (Micro LED) and sub-millimeter Light Emitting Diode (Mini LED).

Wherein the Micro LEDs have a size (e.g., length) of less than 50 microns, e.g., 10 microns to 50 microns. The Mini LED has a size (e.g., length) of 50 microns to 150 microns, such as 80 microns to 120 microns. The embodiment of the present disclosure can selectively set different light emitting devices 12 according to actual requirements.

On this basis, referring to fig. 1, the display device 100 further includes a control box 2. The control box 2 is arranged on one side of the display screen 1 in the first direction X and is connected with the display screen 1. The first direction X is parallel to a surface of the wiring board 11 away from the light emitting device 12.

For example, when the display device 100 is in the upright state as shown in fig. 1, the control box 2 may be disposed on a side of the display screen 1 close to the ground.

Wherein, be equipped with the installation cavity in the control box 2, the installation cavity can be used to set up control system components and parts such as display device 100's mainboard, power strip and transmitting card. The power board may be used to supply power to the display apparatus 100, the main board may control the brightness of the light emitting devices 12 through the power board, and the transmitting card may be used to process communication data.

In the related art, the surfaces of the circuit board 11 and the control box 2 which are close to each other are two planes and are attached to each other. Wherein, the boundary of the surface of the circuit board 11 close to the control box 2 is positioned in the boundary of the surface of the control box 2 close to the circuit board 11. In the assembly process of the display device 100, the circuit board 11 is liable to collide with the control box 2, and in this case, the circuit board 11 may transmit a large stress to the light emitting device 12, easily causing the light emitting device 12 to be damaged. Thus, the display device 100 is difficult to assemble and inefficient to assemble.

Accordingly, in the present application, the structure of the display device 100 is improved, so that the difficulty in assembling the display device 100 can be reduced, and the assembling efficiency of the display device 100 can be improved.

As shown in fig. 3, in some embodiments of the present disclosure, the wiring board 11 includes a first portion 111 and a second portion 112 stacked in the second direction Y, and the light emitting device 12 is disposed on the first portion 111 on a side of the first portion 111 away from the second portion 112. Wherein the second direction Y is perpendicular to the surface of the wiring board 11 away from the light emitting device 12.

Illustratively, the second portion 112 may be a substrate and the first portion 111 may be a conductive layer disposed on the substrate.

Wherein, the substrate can be any one of glass substrate, quartz substrate, sapphire substrate, ceramic substrate, etc.; or a semiconductor substrate such as a single crystal semiconductor substrate or a polycrystalline semiconductor substrate made of Silicon, silicon carbide, or the like, a compound semiconductor substrate made of Silicon germanium or the like, a Silicon On Insulator (SOI), or the like; a film layer made of a material including one or more organic resins such as epoxy resin, triazine, silicone resin, and polyimide may also be used. The conductive layer may be made of any material selected from copper, molybdenum-niobium alloy (MoNb), nickel, and indium tin oxide. The selection can be specifically performed according to actual conditions, and the disclosure does not specifically limit the selection.

On the basis, referring to fig. 4, a gap 113 is left between the first part 111 and the surface of the control box 2 close to the display screen 1, and the second part 112 abuts against the surface of the control box 2 close to the display screen 1. That is, there is a relief space between the first portion 111 of the wiring board 11 and the control box 2.

Arranged in this way, it is possible to reduce the risk of the first portion 111 of the wiring board 11 colliding with the control box 2 during assembly of the display device 100; and the stress transmitted to the light emitting device 12 can be reduced when the wiring board 11 collides with the control box 2. By so doing, the risk of damage to the light emitting device 12 can be reduced.

Illustratively, as shown in fig. 4, the surface of the first portion 111 close to the control box 2 is coplanar with the surface of the second portion 112 close to the control box 2, and is perpendicular to the first direction X. That is, the surface of the wiring board 11 near one end of the control box 2 is a plane, and the plane is perpendicular to the first direction X.

On this basis, referring to fig. 5, the control box 2 includes an escape portion 21 and a support portion 22. The avoiding portion 21 is disposed on one side of the second portion 112 close to the first portion 111, and a gap 113 is left between the first portion 111 and the surface of the avoiding portion 21 close to the display screen 1. The support portion 22 is disposed on a side of the first portion 111 close to the second portion 112, and is connected to the escape portion 21. Moreover, the surface of the support portion 22 close to the escape portion 21 is coplanar with the surface of the escape portion 21 close to the support portion 22, and the second portion 112 abuts against the surface of the support portion 22 close to the display screen 1.

Arranged in this way, a relief space can be formed between the relief portion 21 and the first portion 111, thereby reducing the risk of breakage of the light emitting device 12 during assembly; the support portion 22 can provide support for the wiring board 11 through the second portion 112, thereby improving the reliability of the mounting of the wiring board 11.

The escape portion 21 and the support portion 22 may be integrally formed, or may be separate members that are separately formed and integrally connected by means of bonding, welding, snap-fit connection, screw connection, or the like. The specific choice can be made according to the actual situation, and the disclosure does not specifically limit this.

Illustratively, as shown in fig. 5, the escape portion 21 is integrally formed with the support portion 22. It can be understood that, with this arrangement, not only the structural strength of the control box 2 can be improved, but also the production process flow of the control box 2 can be simplified, and the production efficiency of the control box 2 can be improved.

On the basis, referring to fig. 5 and 6, the surface of the avoiding portion 21 close to the display panel 1 may be parallel to the surface of the supporting portion 22 close to the display panel 1, or may be arranged at an obtuse angle with the surface of the supporting portion 22 close to the display panel 1. The specific choice can be made according to the actual situation, and the disclosure does not specifically limit this.

Illustratively, as shown in fig. 5, a surface of the avoiding portion 21 close to the display screen 1 (shown in fig. 1) is parallel to a surface of the supporting portion 22 close to the display screen 1, and is perpendicular to the first direction X. In this case, the end portions of the relief portion 21 and the support portion 22 close to the display screen 1 may form a stepped structure, so that a gap 113 is formed between the first portion 111 of the circuit board 11 and the relief portion 21, and the second portion 112 of the circuit board 11 abuts against the support portion 22. The structure is simple and easy to realize.

The distance between the avoiding portion 21 and the first portion 111 can be selected according to actual conditions, which is not specifically limited by the present disclosure.

It can be understood that the control box 2 disposed on one side of the circuit board 11 can protect the edge of the circuit board 11 close to the control box 2, and reduce the risk of damage to the circuit board 11. Wherein, the too large distance between the avoiding part 21 of the control box 2 and the first part 111 of the circuit board 11 can weaken the function of the control box 2 for protecting the circuit board 11; if the distance between the escape portion 21 of the control box 2 and the first portion 111 of the circuit board 11 is too small, the escape portion 21 easily collides with the first portion 111 during the assembly process, and the risk of damage to the light emitting device 12 is high.

Based on this, in some embodiments of the present disclosure, the distance between the relief portion 21 and the first portion 111 is set to 0.2mm to 2mm. Arranged in this way, not only can the control box 2 be made to function as a protection for the wiring board 11, but also the risk of breakage of the light emitting device 12 can be reduced.

Illustratively, the spacing between the relief 21 and the first portion 111 may be any one of 0.2mm, 0.3mm, 0.4mm, 0.5mm, 1mm, 1.5mm, and 2mm. The selection can be specifically performed according to actual conditions, and the disclosure does not specifically limit the selection.

The display device 100 provided by the embodiment of the present disclosure includes a display screen 1 and a control box 2, the display screen 1 includes a circuit board 11 and a light emitting device 12 disposed on the circuit board 11, the circuit board 11 includes a first portion 111 and a second portion 112 which are stacked, and the light emitting device 12 is disposed on the first portion 111. A gap 113 is left between the first part 111 and the surface of the control box 2 close to the display screen 1, and the second part 112 abuts against the surface of the control box 2 close to the display screen 1. That is, there is a relief space between the first portion 111 of the wiring board 11 and the control box 2. Arranged in this way, during assembly of the circuit board 11 and the control box 2, the risk of the first portion 111 of the circuit board 11 colliding with the control box 2 can be reduced, thereby reducing the risk of breakage of the light emitting device 12 arranged on the first portion 111. In this way, the assembling difficulty of the display device 100 is reduced, and the assembling efficiency of the display device 100 is improved.

In some embodiments, as shown in fig. 4, the dimension of the first portion 111 in the second direction Y is smaller than or equal to the dimension of the second portion 112 in the second direction Y. The second direction Y is perpendicular to the surface of the wiring board 11 away from the light emitting device 12. That is, the thickness of the second portion 112 is greater than the thickness of the first portion 111.

It is understood that setting the thickness of the second portion 112 to be greater than the thickness of the first portion 111 can increase the contact area between the second portion 112 and the support portion 22, thereby providing more stable support for the wiring board 11. This is advantageous in improving the reliability of mounting the wiring board 11.

In some embodiments, referring to fig. 7, the wiring board 11 includes a plurality of sub-wiring boards 114. The plurality of sub-wiring boards 114 are arranged in a plurality of rows and a plurality of columns, each row including a plurality of sub-wiring boards 114 arranged in the third direction Z, and each column including a plurality of sub-wiring boards 114 arranged in the first direction X. The third direction Z is perpendicular to the first direction X and the second direction Y. Adjacent sub-circuit boards 114 are spliced to each other to form the wiring board 11.

That is to say, the circuit board 11 provided by the embodiment of the present disclosure may be formed by mutually splicing a plurality of sub circuit boards 114. In this way, the large-screen or ultra-large-screen display device 100 can be advantageously manufactured. Moreover, the small-sized sub-circuit boards 114 are spliced to form the large-sized circuit board 11, which is beneficial to reducing the cost.

It is to be understood that, as shown in fig. 8, in the case where the wiring board 11 is formed by splicing a plurality of sub-wiring boards 114 to each other, a plurality of light emitting devices 12 are provided on each sub-wiring board 114, and the plurality of light emitting devices 12 may be arranged in a rectangular array.

In some embodiments, referring to fig. 9, the display screen 1 further comprises a cabinet 13. The case 13 is disposed on a side of the circuit board 11 away from the light emitting device 12, and is connected to the circuit board 11 and the control box 2. In this case, the circuit board 11 can be connected to the control box 2 through the case 13.

Wherein, box 13 accessible screw connection, buckle connection, mode such as bonding, welding, riveting link together with control box 2, specifically can select according to actual conditions, and this disclosure does not do specific limit to this.

Illustratively, the box 13 is connected with the control box 2 by means of screw connection. The method is simple, easy to realize and low in cost.

In the case where the control box 2 includes the support portion 22 and the escape portion 21, the surface of the box 13 close to the control box 2 may be bonded to the surface of the support portion 22 close to the display panel 1. In this case, a numerical control machining (CNC machining) may be performed on the surface of the support portion 22 near the display screen 1 to reduce the roughness of the surface of the support portion 22 near the display screen 1. In this way, the assembly accuracy of the case 13 and the control box 2 can be improved. Meanwhile, the risk of deformation of the box body 13 when the box body is attached to the control box 2 can be reduced.

Exemplarily, the roughness of the surface of the support 22 close to the display screen 1 is less than 10 μm.

It can be understood that the circuit board 11 can also be connected to the case 13 by means of screws, snaps, adhesives, welds, rivets, etc., and can also be attracted to the case 13 by a magnet. The specific choice can be made according to the actual situation, and the disclosure does not specifically limit this.

Illustratively, the circuit board 11 is attracted to the case 13 by a magnet. With the arrangement, the difficulty in assembling the circuit board 11 and the box body 13 is reduced, and the assembling efficiency of the circuit board 11 and the box body 13 is improved.

On this basis, referring to fig. 10, the case 13 may also include a plurality of sub-cases 131. The plurality of sub-boxes 131 are arranged in a plurality of rows and a plurality of columns, each row including a plurality of sub-boxes 131 arranged in the third direction Z, and each column including a plurality of sub-boxes 131 arranged in the first direction X. Adjacent sub-housings 131 are spliced to each other to form the housing 13.

That is, the box body 13 provided by the embodiment of the present disclosure may be formed by splicing a plurality of sub-circuit boards 114. In this way, the large screen or ultra-large screen display device 100 can be advantageously manufactured. Moreover, the small-sized sub-boxes 131 are spliced to form the large-sized box 13, which is beneficial to reducing the cost.

When the case 13 is formed by joining a plurality of sub-cases 131, the adjacent sub-cases 131 may be integrally connected by means of screws, snaps, bolts, rivets, adhesives, or the like. The specific choice can be made according to the actual situation, and the disclosure does not specifically limit this.

It is understood that, as shown in fig. 11, in the case where the wiring board 11 includes a plurality of sub-wiring boards 114 and the case 13 includes a plurality of sub-cases 131, each sub-case 131 may correspond to at least one sub-wiring board 114 and be connected to the corresponding sub-wiring board 114. The boundary of the orthographic projection of the sub-box 131 on the reference surface coincides with the boundary of the orthographic projection of the corresponding sub-circuit board 114 on the reference surface. The reference plane is parallel to the surface of the wiring board 11 remote from the light emitting device 12.

With this arrangement, the sub-box 131 and the corresponding sub-circuit board 114 can be made into a display unit, and the display screen 1 can be formed by splicing a plurality of display units. In this way, it is beneficial to satisfy the diversified requirements of the customer for the size of the display device 100, and the difficulty of assembling the display screen 1 can be reduced.

Each sub-box 131 may correspond to one sub-circuit board 114, or may correspond to multiple sub-circuit boards 114, which may be specifically selected according to actual situations, and this disclosure does not specifically limit this.

Illustratively, as shown in fig. 11, each sub-box 131 corresponds to a plurality of sub-wiring boards 114. In this case, the plurality of sub circuit boards 114 corresponding to each sub box 131 may be arranged in one row, one column, or a plurality of rows and a plurality of columns.

For example, each sub-case 131 corresponds to four sub-wiring boards 114, and the four sub-wiring boards 114 are arranged in a row.

In some embodiments, referring to fig. 4 and 9, the surface of the supporting portion 22 close to the display screen 1 is a ground plane, and the box 13 is electrically connected to the ground plane. It is understood that, in this way, the safety performance of the display apparatus 100 can be improved.
