1. A display module comprising:
a backlight assembly and a display anti-peep assembly, wherein:
the display anti-peep assembly is on a light-exiting side of the backlight assembly; and
the display anti-peep assembly includes a display assembly and an anti-peep assembly;
and the anti-peep assembly at least includes a plurality of light-blocking parts which is arranged along a direction in parallel with a plane wherein the display module is located; and
a first display mode and a second display mode, wherein:
in the first display mode, the anti-peep assembly is in an operating state, and a light-exiting angle of the display anti-peep assembly is α1;
in the second display mode, the anti-peep assembly is not in an operating state, and the light-exiting angle of the display anti-peep assembly is α2, wherein α1<α2;
the display assembly and the anti-peep assembly are independently disposed; and the display assembly is between the backlight assembly and the anti-peep assembly, or the anti-peep assembly is between the backlight assembly and the display assembly;
the anti-peep assembly further includes a first substrate, a second substrate, and a first liquid crystal layer between the first substrate and the second substrate; and the first substrate is on a side of the second substrate facing the backlight assembly;
a first electrode layer is disposed on a side of the first substrate facing the first liquid crystal layer, and a second electrode layer is disposed on a side of the second substrate facing the first liquid crystal layer;
the anti-peep assembly includes at least two light-blocking layers; and along a direction perpendicular to a plane of the first substrate, a first transparent insulating layer is disposed between two light-blocking layers;
each light-blocking layer includes a plurality of first light-blocking sub-parts which is arranged along a direction in parallel with the plane of the first substrate; and along the direction perpendicular to the plane of the first substrate, at least two first light-blocking sub-parts are overlapped with each other to form a light-blocking part of the plurality of light-blocking parts;
the plurality of light-blocking parts is arranged along a first direction; and along the first direction, a distance between two adjacent light-blocking parts is S; and
along the direction perpendicular to the plane of the first substrate, a height of the light-blocking part formed by the at least two first light-blocking sub-parts overlapped with each other is H, wherein S/H=1.
