1. A counter substrate, comprising:
a base substrate;
a bank layer on the base substrate, the bank layer defining a plurality of bank apertures;
a quantum dots material layer on the base substrate, the quantum dots material layer comprising a plurality of quantum dots blocks respectively in at least some of the plurality of bank apertures; and
a support layer on a side of the quantum dots material layer and the bank layer away from the base substrate;
wherein the support layer comprises one or more support portions;
orthographic projections of the one or more support portions on the base substrate are adjacent to a periphery of an orthographic projection of a respective one of the plurality of bank apertures on the base substrate;
the bank layer and the support layer are in an inter-subpixel region of the counter substrate; and
an orthographic projection of the bank layer on the base substrate at least partially overlaps with an orthographic projection of the support layer on the base substrate;
wherein the support layer is a lens layer comprising one or more lens portions; orthographic projections of the one or more lens portions on the base substrate are adjacent to a periphery of an orthographic projection of a respective one of the plurality of bank apertures on the base substrate;
the bank layer and the lens layer are in the inter-subpixel region of the counter substrate; and
an orthographic projection of the bank layer on the base substrate at least partially overlaps with an orthographic projection of the lens layer on the base substrate.
