1. An anti-peeping method of a display screen, comprising a display process and a hiding process, wherein
the display process comprises:
removing a cover from the display screen and an optical sensor; and recognizing, by the optical sensor, a first brightness change, and outputting a first signal, wherein the first brightness change is from dark to bright; and
displaying, by the display screen, a virtual card based on the first signal; and
the hiding process comprises:
completely covering, by the cover, the optical sensor; and recognizing, by the optical sensor, a second brightness change, and outputting a second signal, wherein the second brightness change is from bright to dark; and
canceling, by the display screen, a display of the virtual card based on the second signal;
wherein the optical sensor comprises a first optical sensor and a second optical sensor; and
the step of removing the cover from the display screen and the optical sensor comprises:
outputting the first signal when the first optical sensor recognizes the first brightness change while the second optical sensor does not recognize the first brightness change;
not outputting the first signal when the first optical sensor does not recognize the first brightness change while the second optical sensor recognizes the first brightness change;
outputting the first signal when the first optical sensor and the second optical sensor both recognize the first brightness change; and
not outputting the first signal when the first optical sensor and the second optical sensor both do not recognize the first brightness change;
wherein the first signal comprises a partial display signal and a complete display signal; and
the step of removing the cover from the display screen and the optical sensor comprises:
outputting the partial display signal when the first optical sensor recognizes the first brightness change while the second optical sensor does not recognize the first brightness change;
and displaying, by the display screen, the virtual card to a first preset position based on the partial display signal, such that the virtual card is displayed partially; and
outputting the complete display signal when the first optical sensor and the second optical sensor both recognize the first brightness change; and displaying, by the display screen, the virtual card to a second preset position based on the complete display signal, such that the virtual card is displayed completely.
