Abstract
An anti-peeping assembly and an anti-peeping display device. The anti-peeping assembly includes an anti-peeping component, two frames arranged at a periphery of the anti-peeping component, and two drive modules. The anti-peeping component includes two first substrates and a louver layer sandwiched between the two first substrates. The louver layer includes a plurality of light transmitting parts and a plurality of shading parts adjacent to the plurality of light transmitting parts. The drive module is configured to drive at least one of the two first substrates to move relative to the louver layer in a thickness direction of the first substrates so as to cause the louver layer to be compressed or be recovered from deformation, thereby realizing adjustment of a dimension of each of the light transmitting parts in the thickness direction. The anti-peeping assembly solves a problem that the conventional anti-peeping assembly has fixed and non-adjustable visual angle.
