Two transparent rigid substrates 14 are arranged in parallel and at intervals, respectively having a first inner surface 16 and a second inner surface 18 facing each other. In this embodiment, the first transparent rigid substrate 12 and the second transparent rigid substrate 14 are flat plates shape, but not limited thereto, the first and second transparent rigid substrates 12, 14 may also have a curved surface structure; a liquid crystal switch film 20 is arranged on the first inner surface 16 of the first transparent rigid substrate 12, in one embodiment , the liquid crystal switch film 20 is arranged on the first inner surface 16 with an adhesive (not shown in the figure); and a first sealing structure 22 is arranged on the periphery between the first inner surface 16 and the second inner surface 18, to The space between the first transparent rigid substrate 12 and the second transparent rigid substrate 14 is sealed to form a sealed first hollow space 24 between the first transparent rigid substrate 12 and the second transparent rigid substrate 14 .

Wherein, the liquid crystal switch film 20 is provided with a polymer dispersed liquid crystal (PDLC) between two parallel substrates (not shown) having transparent conductive electrodes.
