The plurality of small-size electronic paper film pieces 2 are sequentially spliced, and the plurality of small-size electronic paper film pieces 2 are electrically connected with the substrate 1. When energized, an electric field is generated between the substrate 1 and the electronic paper film piece 2, and different images and texts can be formed on the electronic paper film piece 2 (here, the principle of electronic paper imaging is a prior art, and will not be described in detail). Since only one substrate 1 is used, instead of the conventional splicing mode of a plurality of small-size substrates (TFT back plate) corresponding to the electronic paper film piece 2, the problem of large gaps in the splicing position of the image is better avoided (a plurality of small-size substrates are spliced together, resulting in that the splicing position cannot be imaged, because the periphery of the substrate has sealing glue or some circuit structures, so that the periphery of the substrate cannot be used for imaging). The combination of a plurality of small-size electronic paper film pieces 2 and a large-size substrate 1 can realize a large-size imaging screen, and effectively reduce the cost, because the cost of the small-size electronic paper film piece 2 is much lower than that of the large-size electronic paper film piece 2, and the size of the substrate 1 (TFT back plate) can be larger and the cost is lower.

[0032] In some embodiments of the present application, as shown in Figure 4 The substrate 1 includes a second base material 11, a driving circuit 12 (thin film transistor circuit) and a glass electrode 13.

[0038] In some embodiments of this application, the first substrate 4 is a waterproof membrane used to prevent moisture from entering the interior of the electronic paper film 2.

[0039] In some embodiments of this application, such as Figure 4 , Figure 5 As shown, a first sealing adhesive 5 is filled between the side of the first substrate 4, the side of the electronic paper film 2, and the side wall of the storage cavity.
