Abstract: A lamp holder for a desk lamp and the desk lamp are disclosed. The lamp holder comprises: a light scattering plate, comprising a first face and a second face arranged oppositely to each other and side faces around ends of the first and second faces. The light scattering plate comprises at least one light-entering side face where light is capable of entering. Light can enter the light scattering plate from the light-entering side face of the light scattering plate, and after being scattered by the light scattering plate, a portion of the light exits from the first face of the light scattering plate and another portion of the light exits from the second face of the light scattering plate. The lamp holder provides not only sufficient lighting in the operational area located below the lamp holder, but also some lighting above the lamp holder.

Abstract: The present disclosure relates to the field of display technology. In particular, a polarization switching device, a display apparatus comprising such a device, and a driving method for such a device are disclosed. Thereby, problems are solved, such as a reduced user experience due to the existing display apparatus incapable of switching the viewing angle range. By disposing the first and second conductive layers in the confined space of such a device, and controlling voltages for the first and second conductive layers, this application can change the size and the direction of the electric field in the confined space. As such, the long axis of the one-dimensional nanometer conductive material located in the confined space can be arranged along the direction of the electric field, so as to form a grating.

Abstract: Provided are underwater spectacles, including a spectacle holder, spectacle belts and an intelligent control system. The intelligent control system includes a warning device, a microprocessor and a plurality of radars. The plurality of radars are respectively disposed on the spectacle holder and the spectacle belts. Input ends of the microprocessor are respectively connected with the plurality of radars, and an output end of the microprocessor is connected with the warning device. The microprocessor acquires signals of the radars, determine obstacle information and/or danger avoiding information around the head of a user, and send the information to the warning device. The warning device receives and provides the user with the obstacle information and/or the danger avoiding information. A control method of the underwater spectacles is also provided.

Abstract: An optical device for a display panel. The optical device comprises an optical element (1). The optical element (1) may include a first surface (3) and a second surface (4) opposite the first surface, and side surfaces. The optical device may further comprise a light source (2) facing one of the side surfaces of the optical element (1). The optical element (1) may comprise a compound containing a photoisomer group. The photoisomer group may undergo a photoisomerization under an irradiation of the light source. Accordingly, an illumination area by a light passing through the first surface (3) and exiting from the second surface (4) may increase or decrease.
