Disclosed herein is a multi biometric terminal that includes a host system capable of recognizing two or more physical features. The host system includes a biometric data input unit configured to acquire biometric data of a user, and a biometric data identification unit configured to compare the acquired biometric data with pre-registered biometric data of the user to perform identification. When a body of the user approaches in a non-contact manner, the biometric data input unit receives a plurality of types of biometric data from the body. The host system is accommodated in a single module or housing.

A display panel assembly and an electronic device including the assembly are disclosed. In one aspect, the assembly includes a window cover including a display area and a non-display area and a display panel disposed on a location of a rear surface of the window cover corresponding to the display area. The assembly further includes a dielectric mirror layer disposed on a location of the rear surface of the window cover corresponding to the non-display area which selectively reflects light incident through the window cover to provide a metallic color sense to a user and a light absorbing layer absorbing light transmitted through the dielectric mirror layer.

An optical structure surface including a plurality of display region groups including a first display region group and a second display region group. In each display region group, an azimuth angle is formed between a projection direction and a reference direction, and a plurality of reflective surfaces belonging to the display region produce an image. A plurality of display regions include a set of display regions whose azimuth angles are different from each other, and the plurality of display regions display an image unique to the display region group in a display direction by a plurality of reflective surfaces of each of the display regions. The display directions of the first display region group and the second display group are different to provide a different brightness to their respective images, in the respective display directions of the images.

An optical system such as an imaging system, projecting system or combined imaging and projecting system, has complex dielectric coatings and/or reflecting polarizers to separate multiple spectral bands and/or polarizations on one or more of the system's curved mirrors.

Optical films are disclosed that include a plurality of interference layers. Each interference layer reflects or transmits light primarily by optical interference. The total number of the interference layers is less than about 1000. For a substantially normally incident light in a predetermined wavelength range, the plurality of interference layers has an average optical transmittance greater than about 85% for a first polarization state, an average optical reflectance greater than about 80% for an orthogonal second polarization state, and an average optical transmittance less than about 0.2% for the second polarization state.

An anamorphic directional illumination device may provide a near-eye display apparatus or a vehicle external light device. The anamorphic near-eye display apparatus comprises a spatial light modulator with asymmetric pixels, an input transverse anamorphic lens; and an extraction waveguide that passes input light in a first direction between a polarisation-sensitive reflector and front guide surface to a lateral anamorphic reflector, and to reflect the light back through the extraction waveguide to guide between the rear guide surface and front guide surface. Reflective extraction features are arranged to extract the reflected light towards the pupil of a viewer, maintaining the directionality of the fan of light rays from the spatial light modulator and anamorphic imaging system. A thin, transparent and efficient anamorphic display apparatus for Augmented Reality and Virtual Reality displays and for scene illumination is provided.

A process for obtaining a decorative mirror includes reflective regions forming a pattern and non-reflective regions, the process including providing a sheet of soda-lime-silica glass coated with a reflective coating on the entirety of one of the faces thereof, then applying a composition including a phosphate salt to the reflective coating, solely in application regions, the application regions being intended to become the non-reflective regions, then tempering the glass sheet, in which the glass sheet is subjected to a temperature of at least 550? C., causing the reflective coating to dissolve in the application regions so as to form the non-reflective regions in which the glass sheet is not coated.

A reflecting element includes a first reflecting film to reflect light and a second reflecting film configured to increase a reflectivity of the first reflecting film. The second reflecting film includes a layer of high-refractive-index material and a layer of low-refractive-index material with a refractive index lower than the layer of high-refractive-index material. The layer of low-refractive-index material is a top layer of the second reflecting film.

An optical stack including an oriented polymeric multilayer optical film and a non-birefringent optical filter is described. The oriented polymeric multilayer optical film has a first reflection band with a first band edge and the non-birefringent optical filter has a first blocking band. In some cases, the first blocking band contains the first band edge and the first blocking band provides a reduction in variation of a band edge of an overall blocking band of the optical stack.

A vehicle interior display system includes: a display device that projects projection light of projection information, and displays the projection information in at least one display region arranged at a position that is visible from the inside of a vehicle compartment; and a control device that controls the display device, and causes the display device to project the projection light. A dimming film that varies light transmittance depending on a voltage value of applied voltage is arranged in the display region or a projection region of a transmitting member for the projection light that is present ahead of a line of sight of an occupant who directs toward the display region in the vehicle compartment.
