Claim 0:
1. An anti-peeping display method for a display apparatus, the display apparatus comprising a display panel and a backlight module, and the backlight module comprising:
a back plate, comprising a bottom plate;
one or more light bars, arranged on a side of the bottom plate, wherein each of the one or more light bars comprises:
a circuit board;
a plurality of first light-emitting units, arranged on the circuit board, and configured to generate diffuse light; and
a plurality of second light-emitting units, arranged on the circuit board, and configured to generate collimated light;

a dimming diaphragm, arranged on a side of the one or more light bars away from the bottom plate, and having a diffusion mode and a transparent mode; and
a driving assembly, arranged on the bottom plate, connected to at least one of the one or more light bars, and configured to drive the light bar to rotate;
wherein, the anti-peeping display method comprises:
determining, by an anti-peeping module, an anti-peeping area;
controlling, by the anti-peeping module, the dimming diaphragm to be alternately switched between the transparent mode and the diffusion mode;
in response to the dimming diaphragm being switched to the transparent mode, disabling, by the anti-peeping module, a part of the first light-emitting units rotating into the anti-peeping area from emitting light and enabling, by the anti-peeping module, a part of the second light-emitting units rotating into the anti-peeping area to emit light; and
in response to the dimming diaphragm being switched to the diffusion mode, disabling, by the anti-peeping module, the part of the first light-emitting units rotating into the anti-peeping area and the part of the second light-emitting units rotating into the anti-peeping area from emitting light.
