  • Patent number: 10684489
    Abstract: The invention relates to a light modulation device for a display for representing two- and/or three-dimensional image content or image sequences. The light modulation device comprises a light modulator and a controller. The phase and/or the amplitude of a light wave field, which is substantially collimated, can be varied by means of the light modulator depending on the location of the light modulator. The light modulator can be actuated by means of the control device. According to the invention, in the direction of propagation of the light wave field, at least one diffracting unit is arranged downstream of the light modulator. The diffracting unit has a variable diffracting structure. By means of the diffracting structure, the light wave field varied by the light modulator can be diffracted in a variable and predeterminable manner. Further, the present invention relates to a display and a method for producing a light modulation device.

  • Publication number: 20200033672
    Abstract: The present invention relates to a device for combining light beams which interact with adjacently arranged pixels of a light modulator. The present invention furthermore relates to a device for beam combination and to a spatial light modulation device for complex-valued modulation. The invention relates to a device for beam combination, and to an optical arrangement of polarization-sensitive component parts which allows complex-valued modulation of a light field by means of a phase-modulating light modulator and a beam combiner, which is insensitive to changes in the incidence direction of the illumination wave. This document furthermore also relates to various arrangements of reflectively operating light modulators.

  • Patent number: 10509364
    Abstract: A light modulator, for a display for the presentation of two- and/or three-dimensional image contents or image sequences, includes two opposing substrates and electrodes. At least one liquid crystal layer is provided between the two substrates. An alignment means is provided on the substrate which faces the liquid crystal layer to set a predeterminable initial alignment of the liquid crystals. The orientation of the liquid crystals can be controlled in a given range through an electric field generated by the electrodes. The alignment means is controllable and can be controlled to modify the initial alignment of the liquid crystals. The alignment can be controlled such the orientation of the liquid crystals can be oriented outside the given range or so that the initial alignment of the liquid crystals can be set specifically for certain positions.
