Abstract
A display apparatus, a control circuit, and an anti-peeping display method are provided. The display apparatus includes a display panel and a backlight module. The anti-peeping display method includes: determining an anti-peeping area; controlling the dimming diaphragm to be alternately switched between a transparent mode and a diffusion mode; in response to the dimming diaphragm being switched to the transparent mode, disabling a part of first light-emitting units rotating into the anti-peeping area from emitting light and enabling a part of 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 the part of the first light-emitting units rotating into the anti-peeping area to emit light and the part of the second light-emitting units rotating into the anti-peeping area from emitting light.
