Referring to fig. 1, fig. 1 is a schematic structural diagram of an LED tiled panel according to a first embodiment of the present application.

The first embodiment of the present application provides an LED tiled panel 100, which includes a substrate 11 and LED devices 12 disposed on the substrate 11. A plurality of the LED devices 12 are arranged in a matrix. The substrate 11 comprises at least two sub-substrates 11a, and a splicing seam M is formed between two adjacent sub-substrates 11a in a splicing manner.

The sub-substrate 11a is provided with a first region D1 adjacent to the splicing seam M. The first region D1 includes first row regions D11 and second row regions D12, and the first row regions D11 and the second row regions D12 are alternately arranged along the column direction Y.

At least one row of the LED devices 12 is disposed in the first row area d 11. At least one row of the LED devices 12 is disposed in the second row area d 12. In the first embodiment, one row of the LED devices 12 is disposed in the first row area d11, and one row of the LED devices 12 is disposed in the second row area d 12; for example, two or more rows of the LED devices 12 are disposed in the first row area d11, and two or more rows of the LED devices 12 are disposed in the second row area d 12. The number of rows of LED devices 12 in the first row zone d11 may be equal to or different from the number of rows of LED devices 12 in the second row zone d 12.

In the column direction Y, the LED devices 12 of the first row section d11 are arranged staggered from the LED devices 12 of the second row section d 12. In the row direction X, the distance between two adjacent LED devices 12 decreases from one end close to the splicing seam M to one end far away from the splicing seam M.

In the LED tiled panel 100 of the first embodiment of the present application, in the column direction Y of the first area D1, the LED devices 12 of the first row area D11 are arranged in a staggered manner with the LED devices 12 of the second row area D12; in the row direction X, the distance between two adjacent LED devices 12 decreases from one end close to the splicing seam M to one end far away from the splicing seam M; so as to improve the visual effect of the splice seam M, and further improve the display effect of the LED splice panel 100.

Specifically, referring to fig. 1, the first embodiment is described by taking an example of splicing two sub-substrates into one substrate 10, but the invention is not limited thereto.

As shown in fig. 1, the sub-substrate 11a disposed on one side of the seam M is a first sub-substrate 111, and the sub-substrate 11a disposed on the other side of the seam M is a second sub-substrate 112. The orthogonal projection of the LED device 12 disposed on the first sub-substrate 111 and the orthogonal projection of the LED device 12 disposed on the second sub-substrate 112 are axisymmetrically disposed.

The orthographic projection of the LED device 12 is the orthographic projection of the LED device 12 on the plane of the substrate 11.

In addition, in some embodiments, the orthographic projection of the LED device 12 on the first sub-substrate 111 and the orthographic projection of the LED device 12 disposed on the second sub-substrate 112 are not axisymmetrically disposed. For example, the pitches of the corresponding LED devices in the first row region disposed in the same row in the first sub-substrate and the second sub-substrate may be different.

Specifically, in the LED tiled panel 100 of the first embodiment, the first sub-substrate 111 and the LED devices 12 thereon are taken as an example for the first embodiment, but the invention is not limited thereto.

In a column of the LED devices 12 closest to the splicing seam M, the distance from the LED device 12 of the first row d11 to the splicing seam M is larger than the distance from the LED device 12 of the second row d12 to the splicing seam M.

In the first embodiment, the row direction X is perpendicular to the column direction Y, and the extending direction of the splicing seam M is perpendicular to the row direction X, but the invention is not limited thereto.

In the first row region d11, the distance between two adjacent LED devices 12 is a first pitch L1, and the difference between two adjacent first pitches L1 is a first difference. In the second row region d12, the distance between two adjacent LED devices 12 is a second distance L2, and the difference between two adjacent second distances L2 is a second difference.

In the first row region d11, two adjacent first spacing distances L1 decrease from one end close to the splicing seam M to one end far away from the splicing seam M. In the second row area d12, two adjacent second spacing distances L2 decrease from one end close to the splicing seam M to one end far away from the splicing seam M.

The distance between two adjacent columns of LED devices 12 on two sides of the splicing seam M in the first row area d11 is the first splicing distance M1; in the second row area d12, the distance between the two columns of LED devices 12 is the second stitching distance m 2; m1 is greater than m 2. For example, m1 ═ 2000 microns, m2 ═ 1800 microns; the target spacing L between two adjacent columns is 1200 microns; but is not limited thereto.

In addition, the first difference and the second difference may be set according to actual conditions, and are not limited herein.

As shown in fig. 1, in the first row d11, two adjacent first differences are equal from the end close to the splicing seam M to the end far from the splicing seam M. In the second row area d12, two adjacent second difference values are equal from one end close to the splicing seam M to one end far away from the splicing seam M. For example, in the first row d11, from the end close to the splicing seam M to the end far from the splicing seam M, the adjacent two first distances L1 are 1800 micrometers, 1600 micrometers and 1400 micrometers in sequence; in the second row area d12, from the end close to the splicing seam M to the end far away from the splicing seam M, the second distance L2 between two adjacent second lines is 1600 micrometers, 1400 micrometers and 1200 micrometers in sequence.

Wherein, the two adjacent first difference values are set equally, so that the first distance L1 between two adjacent columns of the LED devices 12 in the first region D1 is greater than the second distance L2, thereby facilitating gradual and enhanced visual effect. Further, the first difference may be equal to the second difference, or the first difference may be greater than the second difference. When the first difference is larger than the second difference, the gradual change column number of the LED devices 12 can be saved, so that more LED devices can be arranged in the following process.

In some embodiments, as shown in fig. 2, in the first row d11, two adjacent first difference values decrease from the end close to the splicing seam M to the end far from the splicing seam M. In the second row area d12, two adjacent second difference values are equal from one end close to the splicing seam M to one end far away from the splicing seam M. For example, in the first row d11, from the end close to the splicing seam M to the end far from the splicing seam M, the adjacent two first distances L1 are 1600 micrometers and 1400 micrometers in sequence; in the second row area d12, two adjacent second intervals L2 are 1600 micrometers and 1400 micrometers in sequence from one end close to the splicing seam M to one end far away from the splicing seam M.

Further, the first difference of at least one column is greater than the second difference, so that the first distance L1 is smaller than the second distance L2 between at least some adjacent two columns of the LED devices 12 in the first region D1. When the first difference is greater than the second difference, the number of the gradation columns of the LED devices 12 can be saved, so that more LED devices can be arranged in the following.

In some embodiments, in the first row of regions d11, two adjacent first difference values are increased from the end close to the splicing seam M to the end far from the splicing seam M. In the second row area d12, two adjacent second difference values are equal from one end close to the splicing seam M to one end far away from the splicing seam M. For example, in the first row d11, from the end close to the splicing seam M to the end far away from the splicing seam M, the adjacent two first distances L1 are 1800 micrometers and 1400 micrometers in sequence; in the second row area d12, two adjacent second intervals L2 are 1600 micrometers and 1400 micrometers in sequence from one end close to the splicing seam M to one end far away from the splicing seam M.

In summary, in the first row d11, the first difference values may be equal or increased or decreased from the end close to the splicing seam M to the end far from the splicing seam M. In the second row area d12, the second difference values may be equal or increased or decreased from the end close to the splicing seam M to the end far from the splicing seam M.

In the LED tiled panel 100 according to the first embodiment, the sub-substrate 11a is further provided with a second region D2 located on a side of the first region D1 away from the tiled seam M, and the second region D2 is provided with a plurality of LED devices 12.

In the second region D2, distances between any two adjacent columns of the LED devices 12 are equal, the distance between two adjacent columns of the LED devices 12 is a target distance L, and the target distance L is smaller than at least a part of the first distance L1 and the second distance L2, respectively.

Specifically, referring to fig. 3, in the LED tiled panel 200 of the second embodiment, the second embodiment is described by taking an example that two sub-substrates 11a are tiled into one substrate 10, but the invention is not limited thereto.

As shown in fig. 3, the sub-substrate 11a disposed on one side of the splicing seam M is a first sub-substrate 111, and the sub-substrate 11a disposed on the other side of the splicing seam M is a second sub-substrate 112.

Specifically, the distance between two adjacent columns of LED devices 12 located on two sides of the splicing seam M in the first row area d11 is a first splicing distance M1; in the second row area d12, the distance between the two columns of LED devices 12 is the second stitching distance m 2; m2 equals m 1. For example, m1 ═ m2 ═ 1800 micrometers, and the target pitch L between two adjacent columns is 1200 micrometers; but is not limited thereto.

The LED tiled panel 200 of the second embodiment differs from the LED tiled panel 100 of the first embodiment in that: the orthogonal projection of the LED device 12 disposed on the first sub-substrate 111 and the orthogonal projection of the LED device 12 disposed on the second sub-substrate 112 are symmetrically disposed.

The structure of the first sub-substrate 111 of the LED tiled panel 200 of the second embodiment is the same as or similar to the structure of the first sub-substrate 100 of the LED tiled panel 100 of the first embodiment, and is not repeated here.

According to the LED splicing panel, in the column direction of the first area, the LED devices in the first row area and the LED devices in the second row area are arranged in a staggered mode; in the row direction, the distance between two adjacent LED devices is gradually decreased from one end close to the splicing seam to one end far away from the splicing seam; the visual influence of the splicing seam is improved, and the display effect of the LED splicing panel is further improved.
