the area of the first branch 23-i of the first sub-device 21 is equal to the area of the first branch 23-i of the second sub-device 22, and the area of the second branch 23-ii of the first sub-device 21 is smaller than the area of the second branch 23-ii of the second sub-device 22.
It should be noted that the embodiment shown in fig. 3 only schematically shows the relative position relationship between the distance between the first sub-component 21 and the splicing seam C and the distance between the second sub-component 22 and the splicing seam C, and does not represent the actual size; the embodiment shown in fig. 4 only schematically shows a form schematic diagram of the first light emitting device 20, and the form of the first light emitting device in the present application may be other forms, and different angles of the emitted light of the first light emitting device are realized by flexibly setting the form of the first light emitting device, which is not limited in the present application.
Specifically, as shown in fig. 3 and fig. 4, in an embodiment of the present application, the first light emitting device 20 includes a first sub-device 21 and a second sub-device 22, and a distance D1 between the first sub-device 21 and the splicing seam C is greater than a distance D2 between the second sub-device 22 and the splicing seam C along the direction D2 that the display area 10 points to the splicing seam C, which can be understood that the second sub-device 22 is closer to the splicing seam C.
Further, as shown in fig. 3 and fig. 4, the first light emitting device 20 includes a reflective layer 23, the reflective layer 23 makes the light emitted by the first light emitting device 20 incline toward the joint C, the reflective layer 23 includes a first branch portion 23-i and a second branch portion 23-ii connected to each other, the first branch portion 23-i is located on one side of the first light emitting device 20 close to the light emitting surface of the display panel 100, and the second branch portion 23-ii is located on one side of the first light emitting device 20 away from the joint C, optionally, the structure of the first light emitting device 20 in the first display panel 110 and the structure of the second light emitting device 70 are symmetrical with the joint C as a central axis, so that the light emitted by the first light emitting device 20 inclines toward the joint C after being reflected by the reflective structure 40.
Further, as shown in fig. 3 and fig. 4, along a direction D2 in which the display area 10 points to the splicing seam C, an acute angle a1 in an included angle between at least a part of the light rays emitted by the different first light-emitting devices 20 and a direction parallel to the light-emitting surface of the display panel 100 is gradually reduced, and it can be understood that an acute angle a1 in an included angle between at least a part of the light rays emitted by the first sub-device 21 and a direction parallel to the light-emitting surface of the display panel 100 is greater than an acute angle a2 in an included angle between at least a part of the light rays emitted by the second sub-device 22 and a direction parallel to the light-emitting surface of the display panel 100; as can be seen from fig. 4, the specific structure is set as follows: on the premise that the area of the first branch portion 23-I of the first sub-device 21 is equal to the area of the first branch portion 23-I of the second sub-device 22, the area of the second branch portion 23-II of the first sub-device 21 is smaller than the area of the second branch portion 23-II of the second sub-device 22, and it can be understood that the larger the area of the second branch portion 23-II is, the more the light emitted by the corresponding first light-emitting device 20 is inclined towards the direction of the light-emitting surface of the display panel 100, and the larger the moving range of the light emitted by the first light-emitting device 20 towards the direction of the splicing seam C is due to the cooperation of the reflection structure 40, the more the light reflected by the reflection structure 40 is close to the splicing seam C, so that the light intensity around the splicing seam C is effectively compensated; in this embodiment, because the second sub-device 22 is closer to the splicing seam C than the first sub-device 21, the light emitted by the second sub-device 22 needs to cover the position around the splicing seam C after being reflected by the reflection structure 40 to increase the light intensity around the splicing seam C, therefore, the area of the second branch portion 23-ii of the second sub-device 22 is set to be larger than the area of the second branch portion 23-ii of the second sub-device 21, so that the moving range of the light emitted by the second sub-device 22 towards the splicing seam C is larger, the light can be more effectively transmitted around the splicing seam C, and the splicing seam C is further effectively covered.
It should be noted that the intervals between the first light emitting devices 20 may be the same or different, and when the intervals between the first light emitting devices 20 are the same, the brightness around the splicing seam C may be further enhanced by adjusting the angle of the light emitted by the first light emitting devices 20; when the intervals between the first light emitting devices 20 are different, the brightness around the splice line C may be further enhanced by adjusting the intervals between the first light emitting devices 20.
