In one embodiment, the display panel is formed by splicing multiple splicing units 10, and the multiple splicing units 10 are regularly arranged and spliced and fixed. When making a display panel, you can first make a single display screen 101. The display screen 101 does not have a display frame. For example, it can be made by using processes such as side wiring and high-precision cutting. Then the single display screen 101 can be made through an adhesive layer. 102 is bonded to the support plate 100 to realize splicing multiple display screens 101 on the support plate 100 to obtain the splicing unit 10. Then the splicing unit 10 can be spliced with other splicing units 10 for a second time to form a larger size. display panel, thereby reducing the difficulty of the splicing process of the display screen 101 and realizing the free splicing of several display screens 101.

Furthermore, the drive unit box 103 has an accommodation space (not shown) at a position corresponding to the accommodation groove 1001 of the support plate 100 . As shown in Figure 13, since the accommodating groove 1001 is used to avoid and hide the external circuit board 1012 of the display screen 101, the external circuit board 1012 can be placed on the back of the support plate 100 through the accommodating groove 1001. Therefore, it is located on the support plate 100. The drive unit box 103 on the back of the board 100 should have an accommodation space at a position corresponding to the accommodation slot 1001 of the support plate 100. The accommodation space can accommodate the external circuit board 1012, so that the external circuit board 1012 on the back of the support plate 100 can be accommodated. The circuit board 1012 can extend into the drive unit case 103 .
