1. An anti-peeping panel, comprising:
a first substrate;
a second substrate, arranged opposite to the first substrate;
a composite material layer, encapsulated between the first substrate and the second substrate;
a first transparent electrode layer, located on a side facing the composite material layer, of the first substrate and comprising a plurality of first strip-shaped electrodes which are arranged at intervals; and
a second transparent electrode layer, located on a side facing the composite material layer, of the second substrate and comprising a plurality of second strip-shaped electrodes which are arranged at intervals, wherein an orthographic projection of at least one first strip-shaped electrode on the first substrate and an orthographic projection of at least one second strip-shaped electrode on the first substrate have a first overlapping region, wherein
the composite material layer comprises a first composite region and a second composite region, the second composite region overlaps the first overlapping region, and the composite material layer in the second composite region at least comprises two different polymer network skeleton structures;
in response to an electric field of a first frequency being between the first strip-shaped electrodes and the second strip-shaped electrodes, the second composite region shades light, and the first composite region transmits light;
in response to an electric field of a second frequency being between the first strip-shaped electrodes and the second strip-shaped electrodes, the second composite region transmits light, and the first composite region transmits light; and
the first frequency is different from the second frequency.
