Claim 16:
17. The method according to claim 16, wherein the method meets at least one of the following limitations:
forming the nanoparticle sol on the surface of the first transparent cover plate comprises:
orientating a spray head toward the first transparent cover plate, wherein the spray head is provided with a plurality of spray openings, wherein a distribution density of the plurality of spray openings progressively increases from a middle position to positions of two ends along an arrangement direction of the plurality of spray openings or sizes of the plurality of spray openings progressively increase from the middle position to the positions of the two ends along the arrangement direction of the plurality of spray openings, and making the arrangement direction of the plurality of spray openings parallel to a first lateral side of the first transparent cover plate; and
relatively moving the spray head along a second lateral side of the first transparent cover plate, wherein during movement, the spray head sprays the nanoparticle sol to the first transparent cover plate with a moving speed being first increased and then decreased; or

forming the nanoparticle sol on the surface of the transparent substrate thin film comprises:
orientating the spray head toward the transparent substrate thin film, wherein the spray head is provided with a plurality of spray openings, wherein the distribution density of the plurality of spray openings progressively increases from the middle position to positions of two ends along the arrangement direction of the plurality of spray openings or sizes of the plurality of spray openings progressively increase from the middle position to positions of two ends along the arrangement direction of the plurality of spray openings, and making the arrangement direction of the plurality of spray openings parallel to a first lateral side of the transparent substrate thin film; and
moving the spray head along a second lateral side of the transparent substrate thin film, wherein during movement of the spray head, the spray head sprays the nanoparticle sol to the transparent substrate thin film with a moving speed being first increased and then decreased.
