Abstract
An anti-peeping device, an anti-peeping display, and a control method. The anti-peeping device comprises an external light source, a grating mirror structure, and a first controller coupled to the grating mirror structure. The external light source is configured to emit light towards the grating mirror structure, and the first controller is configured to control the grating mirror structure to rotate such that light emitted from the external light source towards the grating mirror structure is reflected to a first direction by the grating mirror structure, the first direction deviating from a normal perpendicular to the horizontal plane of the grating mirror structure.
Claims17
An anti-peeping device comprising:
- an light source, a grating mirror structure, and a first controller coupled to the grating mirror structure,
- wherein the light source is configured to emit light towards the grating mirror structure, and the first controller is configured to control the grating mirror structure to rotate, so that the grating mirror structure reflects the light emitted from the light source towards the grating mirror structure to a first direction, the first direction deviating from a normal perpendicular to a horizontal plane of the grating mirror structure.
An anti-peeping device, comprising a grating mirror structure and a second controller coupled to the grating mirror structure,
- wherein the grating mirror structure is configured to be in a closed state under control of the second controller in response to anti-peeping being activated for the anti-peeping device, so as to prevent light emitted from beneath the grating mirror structure from being emitted out from the grating mirror structure,
- wherein the grating mirror structure comprises a plurality of non-transmissive elements spaced from each other, and the plurality of non-transmissive elements are controlled by the second controller to be in a horizontal state to achieve the closed state of the grating mirror structure.
