Detailed embodiments

[0021] The technical solutions in some embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments provided in the present disclosure, all other embodiments that are apparent to those skilled in the art fall within the scope of the present disclosure.

[0022] Unless the context requires otherwise, throughout the specification and claims, the term "comprising" and its other forms such as the third-person singular "comprises" and the present participle "comprising" are used broadly and inclusively, meaning "including, but not limited to." In describing the specification, the terms "one embodiment," "some embodiments," "exemplary embodiments," "example," "particular example," or "some examples," and the like, are intended to indicate that certain features, structures, materials, or properties associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representations of the above terms do not necessarily refer to the same embodiment or example.Furthermore, the particular features, structures, materials, or properties described may be included in any suitable manner in one or more embodiments or examples.

[0023] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply a relative importance, or to imply the set of specified technical features. Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of the embodiments of the present disclosure, "multiple" means two or more unless otherwise specified.

[0024] “At least one of A, B and C” has the same meaning as “at least one of A, B or C” and includes the following combinations of A, B and C: A only, B only, C only, the combination of A and B, the combination of A and C, the combination of B and C and the combination of A, B and C.

[0025] “A and / or B” includes the following three combinations: A only, B only, and the combination of A and B.

[0026] The use of “suitable for” or “configured for” in this context implies an open and inclusive expression that does not exclude devices that are suitable or configured to perform the additional tasks or steps.

[0027] Furthermore, the use of “based on” is intended to be open and inclusive, since a process, step, calculation, or other action “based on” one or more of the conditions or values ​​may, in practice, be based on additional conditions or values ​​beyond those specified.

[0028] As used herein, "approximately," "about," or "approximately" includes the stated value as well as an average value within an acceptable range of deviation from the specified value, where the acceptable range of deviation is determined by the person skilled in the art taking into account the measurement in question and the errors inherent in measuring the specified quantity (i.e., the limitations of the measurement system).

[0029] As used herein, "parallel," "perpendicular," and "equal" include the stated situation as well as situations that approximate the stated situation within an acceptable range of deviation, where the acceptable range of deviation is determined by the skilled person taking into account the measurement in question and the errors inherent in measuring the particular quantity (i.e., the limitations of the measurement system). "Parallel" includes, for example, absolutely parallel and approximately parallel, where the acceptable range of deviation from approximately parallel may be, for example, a deviation within 5°; "perpendicular" includes absolutely perpendicular and approximately perpendicular, where the acceptable range of deviation from approximately perpendicular may also be, for example, a deviation within 5°.“Equal” includes absolute equality and approximate equality, and it may be within the acceptable range of deviation of approximate equality if the difference between the two, which should be equal, is less than or equal to 5% of either.

[0030] It is understood that where it is stated that a layer or element is on another layer or substrate, it may be located directly on another layer or substrate, or that an intermediate layer may be located between the layer or element and the other layer or substrate.

[0031] Example embodiments are described herein using cross-sections and / or plans depicted as idealized example figures. For clarity, the thickness of the layers and regions is exaggerated in the figures. Accordingly, variations in the shapes in the drawings are conceivable due, for example, to manufacturing techniques and / or tolerances. Therefore, example embodiments should not be construed as being limited to the shapes of the regions depicted herein, but are intended to include manufacturing-related variations in the shapes. For example, an etched region depicted as a rectangle typically includes curved features. Accordingly, the regions depicted in the figures are essentially schematic, and their shapes are not intended to illustrate the actual shapes of regions of the device and are not intended to limit the scope of the example embodiments.

[0032] With the development of display technology, mini LED displays are currently facing a trend of cost reduction. Some large displays use a 40-inch support post as a support device, which is mainly used to support some optical film structures. Therefore, its consumption is very high. For example, a 100-inch display requires 96 support posts, and the 40-inch support posts are all handcrafted. In addition to low labor efficiency, this also results in high costs.

[0033] As in the Fig. 1 and Fig. 2, the light panel 20 comprises a substrate 30 and a plurality of light-emitting elements 32 provided on the substrate. The light-emitting elements 32 are, for example, mini LEDs or micro LEDs. As shown in Fig. 2, the light panel 20 further includes at least one support post 40 provided on the substrate 30.

[0034] In the manufacturing process of mini LED display devices, after the light panels 20 are manufactured, several light panels 20 must be packaged for subsequent processing. As shown in the Fig. 1 and Fig. As shown in Figure 2, several light panels 20 are stacked. To protect the components within the light panels 20, each light panel 20 requires a corresponding supporting and load-bearing structure so that the two adjacent light panels 20 are separated from each other and do not interfere with each other. The support structure is, for example, a carrier plate, so several light panels 20 and several carrier plates are stacked alternately. Finally, the entire structure is placed in a packaging box.

[0035] With reference to Fig. 2 is in Fig. 2 shows a placement structure diagram of light panels 20 welded to support posts 40, in which the light panel 20 is placed flat on the support plate 10 and the support plate 10 is configured to support the light panel 20. In comparison between Fig. 1 and Fig. 2 the height of the light panel 20 in Fig. 2 is significantly enlarged due to the provision of the support posts 40, whereby in Fig. 1 the height H of the light panel 20 is equal to the height h1 of the substrate 30 plus the height h2 of the light element 32, while in Fig. 2 the height H' of the light panel 20 is equal to the height h1' of the substrate 30 plus the height h3 of the support post 40. In Fig. 1, for example, the height H of the light panel 20 is 2 mm, the height h1 of the substrate 30 is 1 mm, and in Fig. 2, the height h3 of the support post 40 is 12 mm, which means that the height H' of the light panel 20 in Fig. 2 13 mm. Here, only the corresponding height of one layer of light panels 20 is shown. In the actual packaging process, the light panels 20 are placed in stacks, as shown in Fig. 1 and Fig. 2. The Fig. 1 and Fig. 2 only show the stacked view of two layers of light panels 20. Therefore, in Fig. 2 compared to Fig. 1, each layer of light panels 20 has an increased height, so the distance P between two adjacent layers of light panels (or the distance between two adjacent support plates) increases. The final increased packaging height is therefore the increased height of each layer of light panels 20 times the number of layers. The larger the number of stacked layers of light panels, the greater the packaging height. Obviously, for the same packaging box, the accommodated packaging volume and thus the number of light panels also decreases, leading to a reduction in production efficiency. In addition, the gradual increase in the specified height of the support posts 40 also leads to a significant increase in packaging and transportation costs. At the same time, it makes the use of welded support posts 40 in large-format displays impossible due to size requirements.

[0036] Based on this, some embodiments of the present disclosure provide a light panel, its support device 200, and a placement method for packaging light panels. By jointly designing the structures of light panels 20 and support devices 200, the packaging volume for the light panels can be doubled, thereby significantly reducing production costs and improving production efficiency, allowing the support posts to be more widely promoted and applied to all mini LED products.

[0037] In the following, according to the present disclosure, a light panel and its carrying device 200 as well as a placement method for packaging light panels are presented.

[0038] In the present disclosure, Fig. 3A, Fig. 5A and Fig. 6A each shows an illustration of a laterally stacked structure of light panels and support devices 200, and Fig. 5B and Fig. 6B each shows an illustration of a planar stacked structure of light panels and support devices 200, wherein to facilitate the description of the entire stack structure Fig. 4A and Fig. 4B each show a stacked structural representation of only one layer of the light panel and the support device 200.

[0039] In some embodiments of the present disclosure, a light panel 20 is provided. As shown in Fig. 3A, Fig. 7 and Fig. 9, the light panel 20 comprises a substrate 30 and a plurality of light-emitting elements 32 provided on the substrate, as well as at least one support post 40 provided on the substrate 30; wherein a plurality of light-emitting elements 32 are arranged in an array on the substrate 30 and the substrate 30 is provided with a plurality of substrate escape holes 31; at least one substrate escape hole 31 is provided on both sides of the support posts 40 in the first direction Y.

[0040] It should be noted that the first direction Y here refers to the horizontal direction perpendicular to the support post 40.

[0041] In some embodiments, the distance between the respective center of the substrate escape hole 31 on both sides of the support post 40 and the support post 40 is the same.

[0042] For example, the substrate escape holes 31 on both sides of the support post 40 are arranged symmetrically with respect to the support post 40, and the center of the substrate escape hole 31 and the center of the support post 40 are on the same straight line.

[0043] In some embodiments, support post 40 includes a post 401 and a base 402 that are connected to each other. Base 402 is closer to substrate 30 than post 401, and base 402 is connected to substrate 31.

[0044] As in Fig. 10, the base 402 of the support post 40 is connected to the substrate 30, and the connected post 401 is provided on the base 402, the post 401 protruding through the substrate escape hole 31 provided on the overlying substrate 30.

[0045] In some embodiments, the height of the support posts 40 is 12-21 mm and the diameter of the base is 5-7 mm.

[0046] In some embodiments, as in Fig. 7 , Fig. 9 and Fig. 10, the substrate 30 on the light panel 20 also includes a conductive metal layer to which the base 402 of the support posts 40 is connected.

[0047] For example, the light-emitting element 32 can be a light-emitting diode (LED), meaning the size of the LED is greater than or equal to 500 µm and the spacing between the LEDs is greater than 2 mm. This means that the LED serves as a point light source of the light panel 20; the conductive metal layer 301 is made of a metal material with good conductivity, such as copper. The base 402 of the support posts 40 is connected to the copper layer on the conductive metal layer.

[0048] In some embodiments, the light panel 20 is used in a backlight module as a backlight source. The backlight module is used in liquid crystal display devices and is provided in a layered stack with the liquid crystal display panel. The backlight module is located on the non-display side of the display panel and provides light to the display panel so that the display device can display.

[0049] In some embodiments of the present disclosure, a carrying device 200 is also provided. As in Fig. 3A, the carrying device 200 includes a plurality of support plates 10. For example, the support plate 10 is a blister plate, and each of the plurality of support plates 10 serves to support one of the above-described light panels 20. Each support plate 10 is provided with a plurality of plate escape holes 11, and each substrate 30 is provided with a plurality of substrate escape holes 31; wherein a plurality of support plates 10 and a plurality of light panels 20 are alternately layered in the second direction X. The plurality of support plates 10 are relatively fixedly positioned, and every two adjacent light panels 20 are positioned offset from each other. The support plate 10 and the adjacent light panel 20 are viewed as a group of packaging structures 100. In the group of packaging structures 100, the light panel 20 is provided on the support plate 10.The positions of at least one of the plurality of plate escape holes 11 and at least one of the plurality of substrate escape holes 31 correspond to each other and serve as an escape hole group 50.

[0050] The support post 40 of the light panel 20 in a relatively lower group of the packaging structures 100 in the second direction X projects through the escape hole group 50 of the at least one relatively upper group of the packaging structures 100; wherein the second direction X is perpendicular to the plane in which the light panel 20 is located, and the second direction X is the direction in which the support post 40 of the light panel 20 faces away from the substrate 30, and the second direction X is perpendicular to the first direction Y.

[0051] It should be noted that a plurality of support plates 10 and a plurality of light panels 20 are provided alternately stacked in the second direction X. This means that the support plates 10 and the light panels 20 are sequentially laid alternately in the second direction X. The position of the support plate 10 is relatively fixed, and the positions of any two adjacent light panels 20 are offset from each other. Here, the reference for the relative fixed positioning is the support plate 10. The position between any one support plate 10 and the support plate 10 in the second direction X is fixed. The reference for the relative offset is the light panel 20. The adjacent light panels 20 are offset from the light panel 20 in the second direction X.

[0052] Escape holes are provided on both the substrate 30 of the light panel 20 and the carrier plate 10. In Fig. 4A and Fig. 4B, the substrate escape hole 31 is a through-hole provided on the substrate 30, and the plate escape hole 11 is a through-hole provided on the support plate 10. In the group of packaging structures 100, the light panel 20 is provided on the support plate 10, and the support plate 10 is configured to support the light panel 20. The positions of at least one of the plurality of plate escape holes 11 and at least one of the plurality of substrate escape holes 31 correspond to each other, and they serve as an escape hole group 50.The corresponding position of the plate escape hole 11 and the substrate escape hole 31 means that in the group of packaging structures 100, the areas enclosed by the boundary line of the orthogonal projection of the substrate escape hole 31 on the carrier plate and the areas enclosed by the boundary line of the plate escape holes 11 at least partially overlap, for example, the areas enclosed by the boundary lines of the two areas completely overlap.

[0053] In this case, the support post 40 of the light panel 20 projects in a relatively lower group of the packaging structures 100 in the second direction X through the escape hole group 50 of the at least one relatively upper group of the packaging structures 100. This saves space, and since the positions of two adjacent light panels 20 are offset from each other, it can be ensured that the support posts 40 on each layer of light panels 20 can pass through the escape hole group 50 of the at least one relatively upper group of the packaging structures 100. In comparison to Fig. 2, the utilization of the limited height can be improved during the step-by-step stacking process. Furthermore, the distance P between two adjacent layers of light panels 20 can be reduced, for example, by half or more than half. Therefore, the size in the first direction Y of the overall structure 1000 consisting of a plurality of light panels 20 and a plurality of support plates 10 can be reduced. That is, the size of the overall structure 1000 in the longitudinal direction can be compressed, so that within a certain height range, for example, with a fixed size of the packaging boxes, the space utilization can be increased due to the increased number of layers of the light panels 20 that can be placed in layered stacks. At the same time, the packaging volume for the light panels 20 is increased, which significantly reduces costs.In addition, since the use of support posts 40 does not have to be eliminated due to packaging problems, more support posts 40 can be used in mini LED display devices.

[0054] In some embodiments, as in Fig. 3B, each support plate 10 comprises at least one first escape region 60, and the first escape region 60 is provided with at least two plate escape holes 11 arranged in the first direction Y; In Fig. 3C, each light panel 20 includes at least one second escape region 70. The second escape region 70 is provided with at least two substrate escape holes 31 and a support post 40 arranged in the first direction Y. At least one second escape hole 41 is provided on both sides of the support post 40 in the first direction Y; the positions of the first escape region 60 and the second escape region 70 correspond to each other in the second direction X. The positions of any two adjacent light panels 20 are offset from each other in the first direction Y.

[0055] As in Fig. 3A, the second direction X is the direction in which the support post 40 of the light panel 20 is directed away from the substrate 30. The first direction Y is perpendicular to the second direction X, with the support plate 10 shown in Fig. 3B and the light panel 20 shown in Fig. 3C can form a group of packaging structures 100, i.e. the plan representation of the Fig. 3B and Fig. 3C, as in Fig. 4A shown. Fig. 4A is a form of a packaging adjustment unit 80 included in the group of packaging structures 100. The packaging adjustment unit 80 includes two plate escape holes 11 and a support plate unit of the support plate 10, as well as two substrate escape holes 31 and a support post 40 of the light panel 20 located between the two substrate escape holes 31; As shown in Fig. 4B, Fig. 4B shows another form of a packaging adjustment unit 80 of a group of packaging structures 100. The packaging adjustment unit 80 includes three plate escape holes 11 and a support plate unit of the support plate 10, as well as four substrate escape holes 31 and a support post 40 of the light panel 20 located in the center of the four substrate escape holes 31.

[0056] In some embodiments, the first escape region 60 of the carrier plate 10 is provided with N plate escape holes 11, and the second escape region 70 of the light panel 20 is provided with M substrate escape holes 31; The support post 40 of the light panel 20 in a relatively lower group of the packaging structures 100 in the second direction X protrudes through the escape hole group 50 of the at least L relatively upper groups of the packaging structures 100; where N=L+1, M=2L.

[0057] In some embodiments, as in Fig. 3A, the center of the plate escape hole 11 and the substrate escape hole 31 of an escape hole group 50 lies on a horizontal line with the center of the support post 40.

[0058] It is understood that the first escape area 60 of the carrier plate 10 and the second escape area 70 of the light panel 20 form a packaging adaptation unit 80.

[0059] For example, in the Fig. 5A and Fig. 5B, Fig. 5B is an illustration of a planar stacked structure of Fig. 5A, wherein the first escape area 60 of the support plate 10 is provided with two plate escape holes 11, and the second escape area 70 of the light panel 20 is provided with two substrate escape holes 31. The two substrate escape holes 31 are provided on both sides of the support post 40.

[0060] The support post 40 of the light panel 20 in a relatively lower group of the packaging structures 100 in the second direction X projects through the escape hole group 50 of the relatively upper group of the packaging structures 100; The positions of the plurality of light panels 20 are periodically provided in groups of two light panels 20 each in the second direction X.

[0061] As in Fig. 5A, the support posts 40 of the light panels 20 in the relatively lower group of packaging structures 100 extend through the escape hole groups 50 of the relatively upper group of packaging structures 100, so that L is 1, N is 2, and M is 2. In Fig. 5A, the positions of the plurality of light panels 20 are provided periodically in groups of two light panels 20 each, wherein the positions of the light panels 20 located on the adjacent layers are offset from each other in the second direction X and the positions of the light panels 20 located on every other layer are relatively fixed.

[0062] For example, in the Fig. 6A and Fig. 6B, Fig. 6B is an illustration of a planar stacked structure of Fig. 6A, wherein the first escape area 60 of the support plate 10 is provided with three plate escape holes 11, and the second escape area 70 of the light panel 20 is provided with four substrate escape holes 31. Two substrate escape holes 31 are provided on each side of the support post 40.

[0063] The support post 40 of the light panel 20 in a relatively lower group of the packaging structures 100 in the second direction X projects through the escape hole group 50 of the relatively upper group of the packaging structures 100; and the positions of the plurality of light panels 20 are periodically provided in groups of three light panels 20 each in the second direction X.

[0064] As in Fig. 6A, the support posts 40 of the light panels 20 in the relatively lower group of packaging structures 100 extend through the escape hole groups 50 of the relatively upper group of packaging structures 100 such that L is 2, N is 3, and M is 4, wherein with reference to Fig. 6A the positions of the light panels 20 located on the adjacent layers are offset from each other in the second direction X and the positions of the light panels 20 located on every third layer are relatively fixed

[0065] It should be noted that the relative offset here can be to the left or right in the first direction Y. Regardless, the offset here remains the same.

[0066] In some embodiments, as in the Fig. 5B and Fig. 6B, each support plate 10 includes a plurality of first escape areas 60 arranged in the third direction Z, and each of the first escape areas 60 is provided with at least two plate escape holes 11 arranged in the direction Y; as shown in Fig. 7, each light panel 20 includes a plurality of second escape regions 70 arranged in the third direction Z, and each of the second escape regions 70 is provided with at least two substrate escape holes 31 and one support post 40 arranged in the first direction Y.

[0067] With reference to the Fig. 5A, Fig. 5B, Fig. 6A and Fig. 6B, in a group of packaging structures 100, the positions of each of the first escape areas 60 and a second escape area 70 correspond in the second direction X.

[0068] As in Fig. As shown in Figure 7, the third direction Z and the first direction Y intersect, with the third direction Z being parallel to the direction of the longer axis of the light panel 20 and the first direction Y being parallel to the direction of the shorter axis of the light panel 20. Therefore, the third direction Z and the first direction Y are perpendicular to each other.

[0069] In some embodiments, as in Fig. 5B and Fig. 6B, in the first direction Y, the distance L1 between the centers of two adjacent plate escape holes 11 is equal to the distance L2 from the center of the support post 40 to the centers of the adjacent substrate escape holes 31.

[0070] For example Fig. 6B, the two adjacent plate escape holes 11 are a first plate escape hole 111 and a second plate escape hole 112, respectively, and the distance between the plate escape hole 111 and the plate escape hole 112 is L1. The adjacent substrate escape holes 31 are a first substrate escape hole 311 and a second substrate escape hole 312, respectively, and the distance from the center of the support post 40 to the first substrate escape hole 311 and the distance from the center of the support post 40 to the second substrate escape hole 312 is L2, where L1=L2.

[0071] In some embodiments, the distance between the centers of two adjacent plate escape holes 11 is equal to the distance between the centers of two adjacent substrate escape holes 31. No support post 40 is provided between the two adjacent substrate escape holes 31.

[0072] For example Fig. 6B, the two adjacent plate escape holes 11 are each a first plate escape hole 111 and a second plate escape hole 112, and the distance between the first plate escape hole 111 and the second plate escape hole 112 is L1. The adjacent substrate escape holes 31 are each a third substrate escape hole 313 and a fourth substrate escape hole 314, and the distance between the center of the third substrate escape hole 313 and the center of the fourth substrate escape hole 314 is L3, where L1=L3.

[0073] It follows that L1=L2=L3, equal to the offset of the light panels 20.

[0074] In some embodiments, the maximum dimension D of the cross-section of the support posts 40 is smaller than the size D1 of the plate escape hole 11 and smaller than the size D2 of the substrate escape hole 31.

[0075] With reference to Fig. 3A, Fig. 3B and Fig. 3C, the maximum dimension D of the cross-section of the support posts 40 corresponds to the maximum size of the bottom surface of the support posts 40. From the figures, it can be seen that D is smaller than D1 and D is smaller than D2. Such dimensioning can facilitate the passage of the support post 40 through the plate escape hole 11 and the substrate escape hole 31.

[0076] In some embodiments, the size D1 of the plate escape hole 11 is equal to the size D2 of the substrate escape hole 31.

[0077] In Fig. 3A, the size D1 of the plate escape hole 11 is equal to the size D2 of the substrate escape hole 31, i.e., D1=D2. By equalizing the two sizes, product manufacturing can be made easier and more efficient. On the other hand, the reference point for adjustment and installation can be quickly determined when placing light panels 20 and support plates 10 in alternating layers.

[0078] In some embodiments, the shape of the plate escape hole or the substrate escape hole is circular, square, or polygonal.

[0079] It should be noted that the plate escape hole 11 and the substrate escape hole 31 can be formed in different shapes. Fig. 3A, the plate escape hole 11 and the substrate escape hole 31 have a circular shape. The above is only an example of the shapes of the plate escape holes 11 and the substrate escape holes 31. The shapes of the escape holes can also be square or polygonal and are not limited to these shapes.

[0080] In some embodiments, at least two adjacent plate escape holes 11 of the support plate 10 are adjacent to each other, becoming a slot 113.

[0081] For example, in Fig. 8, the size of the two adjacent plate escape holes 11 is relatively large, and the distance is 0, that is, the two adjacent plate escape holes 11 merge into a larger elongated hole 113.

[0082] In some embodiments, the support posts 40 have a conical structure and the support posts 40 taper in the second direction X.

[0083] For example, in Fig. 3A, Fig. 9 and Fig. As shown in Figure 10, the support posts 40 are quasi-conical, and their top and bottom surfaces are both circular. The support posts 40 taper in the second direction X. It should be understood that their outer dimensions gradually decrease in a certain ratio in the second direction X, that is, from the bottom surface to the top surface of the support posts 40.

[0084] The embodiments of the present disclosure also provide a placement method for packaging light panels. The placement method includes placing the first layer of the carrier plate 10 as the bottom layer of the carrier plate 10 and placing light panels 20 and carrier plates 10 sequentially on the bottom layer of the carrier plate 10 until the last layer of the light panel 20 is placed on the last layer of the carrier plate 10.

[0085] As in the Fig. 3A, Fig. 5A and Fig. 6A, a plurality of support plates 10 and a plurality of light panels 20 are provided alternately in the second direction X, and the adjacent support plates 10 and light panels 20 serve as a group of packaging structures 100, and the light panel 20 is provided on the support plate 10; the light panel 20 includes a substrate 30 and at least one support post 40 provided on the substrate 30.

[0086] Each carrier plate 10 is provided with a plurality of plate escape holes 11, and each substrate 30 is provided with a plurality of substrate escape holes 31.

[0087] The positions of the plurality of support plates 10 are relatively fixed, and the positions of any two adjacent light panels 20 are offset from each other. In a group of packaging structures 100, the positions of at least one plate escape hole 11 and at least one substrate escape hole 31 correspond to each other and serve as an escape hole group 50. The support post 40 of the light panel 20 in a relatively lower group of packaging structures 100 in the second direction X protrudes through the escape hole group 50 of the at least one relatively upper group of packaging structures 100.

[0088] For example Fig. 3A, Fig. 5A and Fig.6A, first, the first layer of the support plate 10 is placed on which the first layer of the light panel 20 is placed; on the side of the first layer of the support plate 10 facing away from the first layer of the support plate 10, the second support plate 10 is placed, and the support post 40 of the first layer of the light panel 20 is passed through the plate escape hole 11 of the second layer of the support plate 10.

[0089] On the side of the second layer of the carrier plate 10 facing away from the second layer of the carrier plate 10, the second light panel 20 is placed, and the support post 40 of the first layer of the light panel 20 is passed through the substrate escape hole 31 of the second layer of the light panel 20.

[0090] On the side of the second layer of the light panel 20 facing away from the first layer of the support plate 10, the third support plate 10 is placed, and the support post 40 of the second layer of the light panel 20 is passed through the plate escape hole 11 of the third layer of the support plate 10.

[0091] On the side of the third layer of the support plate 10 facing away from the second layer of the support plate 10, the third light panel 20 is placed, and the support post 40 of the second layer of the light panel 20 is passed through the substrate escape hole 31 of the third layer of the light panel 20.

[0092] The above-mentioned placement method for packing light panels indicates a cycle in which it is arranged one after another in alternating layers of stacks.

[0093] The advantageous effects of the light panel 20 and the placement method for packaging light panels in the above-mentioned embodiments of the present disclosure are the same as the advantageous effects of the support device 200 described in the above-mentioned embodiments and will not be explained again here.

[0094] The above embodiments are merely specific embodiments of the present disclosure, but the scope of the present disclosure is not limited thereto. Any variations or alternatives conceivable to a person skilled in the art within the scope of the techniques disclosed by the invention should be considered within the scope of the present disclosure. Therefore, the scope of the present disclosure should be governed by the claims.
