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.

Abstract: A LIDAR system including a MEMS scanning device is disclosed. The LIDAR system includes a light source, a light deflector, a sensor, and a processor. The light deflector deflects light from the light source or light received from an environment outside a vehicle in which the LIDAR system is installed. The sensor detects the light received from the light source or the environment. The processor determines a distance of one or more objects in the environment from the vehicle based on the signals from the sensor. The light deflector includes one or more actuators, which include one or more actuating arms. Connectors connect the actuating arms to an MEMS mirror or other deflector. The actuating arms move when subjected to an electrical field in the form of a voltage or current. Movement of the actuating arms causes movement of the MEMS mirror or deflector causing it to deflect light.
