[0039] The plurality of light emitting areas 10 comprises a regular light emitting area 11 and an edge light emitting area 12, the area of the edge light emitting area 12 is smaller than the area of the regular light emitting area 11; the shape of the edge light emitting area 12 is the same as the shape of a part of the regular light emitting area 11, and the arrangement mode of the sub-light emitting unit 20 in the edge light emitting area 12 is the same as the arrangement mode of the sub-light emitting unit 20 in the part of the regular light emitting area 11.

[0040] Specifically, the substrate can be a flexible substrate or a rigid substrate. For example, the substrate can be a glass substrate or a PI substrate. The sub-light emitting unit 20 can be an organic light emitting unit or other light emitting unit. When the sub-light emitting unit 20 is an organic light emitting unit, the sub-light emitting unit 20 can include a first electrode, a second electrode, and a light emitting layer disposed between the first electrode and the second electrode.

[0041] The light emitting device can include a plurality of light emitting areas 10, each of which independently emits light. By setting the shape of the light emitting area 10 to be a polygon and the shape of the light emitting unit 20 to be a triangle, each light emitting unit 20 in each light emitting area 10 can be uniformly distributed, improving light emitting uniformity. In addition, the number of triangular light emitting units 20 can be increased or decreased according to the specific shape of the light emitting area 10. By adjusting the number of triangular light emitting units 20, the light emitting area 10 of any different shape can be adapted, so that the edge shape of the edge light emitting area 12 adapts to the different shapes of the edge of the light emitting device.

The area of the edge light emitting area 12 is smaller than that of the regular light emitting area 11. The shape of the edge light emitting area 12 is the same as that of a part of the regular light emitting area 11, and the arrangement of the sub-light emitting units 20 in the edge light emitting area 12 is the same as that in the part of the regular light emitting area 11. That is, the regular light emitting area 11 includes a preset area, the shape and size of the edge light emitting area 12 are the same as those of the preset area, and the arrangement of the sub-light emitting units 20 in the edge light emitting area 12 is the same as that in the preset area. For example, the shape of the regular light emitting area 11 is a hexagon, and the shape and size of the edge light emitting area 12 are the same as those of the regular light emitting area 11 after removing a part of the regular light emitting area 11. The arrangement of the sub-light emitting units 20 in the edge light emitting area 12 is the same as that of the regular light emitting area 11 after removing a part of the regular light emitting area 11. In this way, without setting a special-shaped light emitting unit, the different edge shape requirements of the light emitting device can be met, and the design difficulty is reduced. For example, referring to Figure 2 and Figure 3 The edge light emitting area 12 of the present embodiment can meet the requirements of the curved edge, the polyline edge, etc. of the light emitting device.

[0043] The embodiment of the utility model discloses each light emitting area 10 includes a plurality of sub light emitting unit 20, the shape of light emitting area 10 is polygon, the shape of sub light emitting unit 20 is triangle, the area of edge light emitting area 12 is less than the area of regular light emitting area 11, the shape of edge light emitting area 12 is same with the shape of the partial area of regular light emitting area 11, and the arrangement mode of sub light emitting unit 20 in edge light emitting area 12 is same with the arrangement mode of sub light emitting unit 20 in the partial area of regular light emitting area 11.

And through setting the triangular sub light emitting unit 20 and polygon light emitting area 10, and setting the shape of edge light emitting area 12 is same with the shape of the partial area of regular light emitting area 11, and the arrangement mode of sub light emitting unit 20 in edge light emitting area 12 is same with the arrangement mode of sub light emitting unit 20 in the partial area of regular light emitting area 11, need not to set the special-shaped light emitting unit, can satisfy the edge requirement of different shape of light emitting device, reduced the design difficulty, and guaranteed the light emitting uniformity of light emitting device.

Illustratively, the drive line 40 is electrically connected with the first electrode of the sub light emitting unit 20, and the drive line 40 transmits drive signal to the first electrode of the sub light emitting unit 20, and the sub light emitting unit 20 is driven to emit light. The anti short circuit wire 30 is used to avoid the short-circuit current when the sub light emitting unit 20 is short-circuited, which leads to the overheating of the sub light emitting unit 20 and affects the light emission of the whole light emitting area 10. By setting the anti short circuit wire 30 for every sub light emitting unit 20, it can be ensured that any one sub light emitting unit 20 does not affect the light emission of the light emitting area 10 when it is short-circuited.

[0046] Reference Figures 2-5, in order to ensure the uniformity of light emission, the anti-short-circuit trace 30 of each sub-light-emitting unit 20 needs to meet certain resistance requirements. For example, when the light-emitting area of each sub-light-emitting unit 20 is the same, the resistance of the anti-short-circuit trace 30 of each sub-light-emitting unit 20 needs to be consistent. When the light-emitting device has a special-shaped edge, in the prior art, in order to meet the special-shaped edge of the light-emitting device, a sub-light-emitting unit 20 with an area different from other sub-light-emitting units 20 is usually arranged, and the anti-short-circuit resistance of the sub-light-emitting unit 20 needs to be adjusted accordingly, which is difficult to design. In this embodiment, the sub-light-emitting unit 20 is triangular, the shape of the edge light-emitting area 12 is the same as that of the partial area of the regular light-emitting area 11, and the arrangement mode of the sub-light-emitting unit 20 in the edge light-emitting area 12 is the same as that of the sub-light-emitting unit 20 in the partial area of the regular light-emitting area 11, and the sub-light-emitting unit 20 in the edge light-emitting area 11 is a complete triangle, which can meet the requirement of the special-shaped edge of the light-emitting device, and the resistance of the anti-short-circuit trace of the edge light-emitting area 12 does not need to be redesigned, which is simple to design. For example, through the design of the edge light-emitting area 11, the curved edge requirement of the light-emitting device can be met, and the visual effect can be improved.

[0047] Optionally, referring to Figure 1 and Figure 2 , the plurality of light-emitting areas 10 include a regular polygon light-emitting area, and the number of the sub-light-emitting units 20 in the regular polygon light-emitting area is m×4 (n-1) , where m is an integer greater than or equal to 4, m is the number of sides of the polygon, and n is an integer greater than or equal to 1.

[0048] where m can be 4, 5, 6, 7, 8, etc. The number of the sub-light-emitting units 20 in the regular polygon light-emitting area is m×4 (n-1) , which means that the m-sided regular polygon is divided into m first triangles, each side of the m-sided regular polygon is used as the bottom side of each first triangle, and the center of the m-sided regular polygon is used as the top point of the first triangle; when n = 1, one sub-light-emitting unit 20 is arranged in each first triangle; when n = 2, each first triangle is further divided into four second triangles, and one sub-light-emitting unit 20 is arranged in each second triangle; when n = 3, each second triangle is further divided into four third triangles, and one sub-light-emitting unit 20 is arranged in each third triangle, and so on. Each first triangle can be arranged with 4 (n-1) sub-light-emitting units 20, and the regular polygon light-emitting area can be arranged with m×4 (n-1) sub-light-emitting units 20. This division method can make the shapes and areas of the small triangles divided in the regular polygon the same, the shapes and areas of all the sub-light-emitting units 20 arranged in the regular polygon can be the same, the sub-light-emitting units 20 can be arranged uniformly in the polygon, the light-emitting uniformity of the light-emitting area can be improved, and the light-emitting area 10 has more sub-light-emitting units 20, and the aperture ratio is improved. For example, referring toFigure 2 , the regular polygon light-emitting area is a hexagonal light-emitting area, n=2, the hexagonal is divided into 6 first triangles, each first triangle is divided into 4 identical second triangles, that is, 4 identical sub light-emitting units 20 are arranged in each first triangle, the number of sub light-emitting units 20 in the hexagonal light-emitting area is 6*4=24, and the 24 sub light-emitting units 20 are uniformly arranged in the hexagonal light-emitting area.

[0049] Optionally, referring to Figure 1 and Figure 2 , n is an integer greater than or equal to 2.

[0050] In this way, the number of sub light-emitting units 20 in the polygon light-emitting area is more, and the size of each sub light-emitting unit 20 is smaller, while ensuring uniform light emission, the edge requirements of different shapes of the light-emitting device can be met, and the design difficulty is reduced. Optionally, the side length of the regular polygon light-emitting area is a, and the bottom side length of the sub light-emitting unit 20 in the regular polygon light-emitting area is b, 0 (n-1) , wherein a and b are positive numbers.

[0052] Optionally, a is less than or equal to 100 mm, and can be 20 mm, 50 mm, 80 mm, 100 mm, etc.

[0053] Figure 6 is a light-emitting area distribution schematic diagram of a light-emitting device provided by an embodiment of the present application. Referring to Figure 6 , the plurality of light-emitting areas includes quadrilateral light-emitting areas 21 and octagonal light-emitting areas 22, and every four octagonal light-emitting areas 22 surround a quadrilateral light-emitting area 21;

[0054] Alternatively, referring to Figure 1 , the plurality of light-emitting areas includes hexagonal light-emitting areas 23, and the plurality of hexagonal light-emitting areas 23 are arrayed.

[0055] Specifically, referring to Figure 2 , 8*4 (n-1) triangular sub light-emitting units 20 can be uniformly placed in each octagonal light-emitting area 22, and 4*4 (n-1)The size of the plurality of sub-light emitting units 20 in each octagonal light emitting area 22 is the same, and the size of the plurality of sub-light emitting units 20 in each square light emitting area 21 is the same. The light emitting device provided with the octagonal light emitting area 22 and the quadrilateral light emitting area 21 can meet different light emitting pattern requirements, and the light emitting areas are closely arranged, thereby improving the aperture ratio of the light emitting device.

[0056] Reference Figure 1 And Figure 2 The size of the plurality of sub-light emitting units 20 in each hexagonal light emitting area 23 is the same, and the plurality of sub-light emitting units 20 are uniformly arranged. The light emitting device provided with the hexagonal light emitting area 23 can meet different light emitting pattern requirements, and the light emitting areas are closely arranged, thereby improving the aperture ratio of the light emitting device.

[0057] Optionally, the size of the plurality of sub-light emitting units 20 in the same light emitting area 10 is the same.

[0058] In this way, the sub-light emitting units 20 in each light emitting area 10 can adopt the same short-circuit prevention wire 30 with the same resistance, thereby reducing the design difficulty. Moreover, the light emitting of each light emitting area 10 is more uniform.

[0059] Figure 7 is a driving line schematic diagram of the light emitting device provided by the embodiment of the present application, Figure 8 is Figure 7 Reference Figure 7 and Figure 8 The driving line includes a main line 41 and an auxiliary line 42. The main line 41 is arranged around the light emitting area, and the auxiliary line 42 is arranged in the area surrounded by the main line 41. The auxiliary line 42 is in a grid shape, and each sub-light emitting unit 20 is arranged in a grid.

[0060] The line width of the main line 41 is greater than the line width of the auxiliary line 42.

[0061] The driving signal is transmitted to each light emitting area through the main line 41. The line width of the main line 41 is greater than the line width of the auxiliary line 42, which can effectively reduce the resistance of the main line 41, reduce the voltage drop in the driving signal transmission process, ensure that the driving signals transmitted to each light emitting area are not greatly different, and ensure that the light emitting between the light emitting areas is uniform. By arranging the auxiliary line 42 in a grid shape, the driving signals transmitted to each sub-light emitting unit 20 in each light emitting area are basically consistent, the light emitting brightness of each sub-light emitting unit 20 in the same light emitting area is consistent, and the light emitting uniformity of the sub-light emitting units 20 in the light emitting area is improved.

[0062] Optionally, the main lines 41 of the plurality of light emitting areas adjacent in the first direction X are electrically connected to each other.

[0063] In this way, the plurality of light emitting areas adjacent along the first direction X can be controlled to emit light at the same time, and the driving difficulty and the wiring difficulty of the driving lines can be reduced.

[0064] Optionally, the line width of the main line 41 is greater than or equal to 10 um and less than or equal to 10 mm, and can be 10 um, 20 um, 50 um, 100 um, 500 um, 1 mm, 5 mm, 10 mm, etc.

[0065] The wider the line width of the main line 41, the smaller the resistance of the main line 41. However, if the line width of the main line 41 is too wide, it will occupy too much space and affect the aperture ratio. By setting the line width of the main line 41 to be greater than or equal to 3 mm and less than or equal to 5 mm, the main line 41 can have a small resistance, reduce the transmission loss of the driving signal, and ensure that the main line 41 does not occupy too much space, and the light emitting device has a large aperture ratio.

[0066] The inventors have found through experiments that when the size of the light emitting area is less than or equal to 5 cm, the arrangement of the present embodiment can ensure that the light emitting brightness of the same row of light emitting areas connected along the first direction X has a difference of 20%, and has high light emitting uniformity.
