It can be understood that, because it is a plurality of be in the same place through the physics concatenation between the lamp plate 150, can't accomplish zero piece, consequently, adjacent two must exist between the lamp plate 150 piece region 103.

In an exemplary embodiment, the number of the lamp panels 150 may be 2 to 10, for example, 2, 5, 8, 10, or other numbers, and the specific number of the lamp panels 150 may be determined according to the size of the display panel 30 and the size of the lamp panels 150, which is not limited in this application.

Referring to fig. 2, fig. 2 is a schematic front view of a display panel according to a second embodiment of the present application. The display panel 30 provided by the embodiment of the application has a first area 301 and at least one second area 302, and because the lamp panels are spliced, one second area is clamped between the two first areas; the first region 301 corresponds to the region where the lamp panel 150 is located, and the second region 302 corresponds to the position where the seam splicing region 103 is located. That is, the orthographic projection of the first area 301 on the back panel 110 corresponds to the orthographic projection of the lamp panel 150 on the back panel 110, and the orthographic projection of the second area 302 on the back panel 110 corresponds to the orthographic projection of the patchwork area 103 on the back panel 110. The first area 301 receives a greater intensity of light than the second area 302.

As shown in fig. 2, in the present embodiment, the display panel 30 may include at least a plurality of first sub-pixels 50 distributed in an array and a plurality of second sub-pixels 60 distributed in an array, where the plurality of first sub-pixels 50 are located in the first area 301, and the plurality of second sub-pixels 60 are located in the second area 302. The first sub-pixel 50 includes a first main pixel 51 and a first sub-pixel 52, and the second sub-pixel 60 includes a second main pixel 61 and a second sub-pixel 62.
