1. A dimming glass, comprising:
a glass substrate; and
at least two dye liquid crystal cells on the glass substrate; wherein the at least two dye liquid crystal cells are mutually stacked and bonded with each other via an adhesive layer; and
at least one of the dye liquid crystal cells comprises a central region and a peripheral region surrounding a periphery of the central region; and
wherein the at least one of the dye liquid crystal cells comprises a cell gap adjusting structure in at least the peripheral region, and the cell gap adjusting structure is configured to adjust a cell gap of the at least one of the dye liquid crystal cells to be consistent,
the at least one of the dye liquid crystal cells comprises a first substrate, a second substrate, dye liquid crystals, and a plurality of support elements, the first substrate and the second substrate are assembled to form a cell gap in which the dye liquid crystals are disposed; the plurality of support elements are distributed between the first substrate and the second substrate at intervals, and configured to support the first substrate and the second substrate; and each support element comprises a body;
the cell gap adjusting structure comprises a dielectric elastomer and an electrode structure; the dielectric elastomer is in the body and the electrode structure is on the first substrate and/or the second substrate, and an orthographic projection of the electrode structure on the first substrate is overlapped with an orthographic projection of the support elements on the first substrate; and
the at least one of the dye liquid crystal cells further comprises a first electrode layer and a second electrode layer, each of which is disposed in the first substrate or the second substrate, light amount transmitted through the dimming glass is adjusted under an electric field formed between the first electrode layer and the second electrode layer, the first electrode layer comprises a first pattern and a second pattern mutually insulated, the first pattern has an orthographic projection on the first substrate overlapped with an orthographic projection of the support elements on the first substrate and constitutes part of the electrode structure, and an orthographic projection of the second pattern on the first substrate is overlapped with an orthographic projection of other region than a region where the support elements are located on the first substrate.
