Abstract:
1. Display device for three-dimensional representation of a 3D scene, which is visible for an observer eye from at least one visibility region, With a controllable device for tracking the at least one visibility region in an observer plane, including: With a controllable spatial light modulator (SLM) with a pixel matrix which modulates the light, and With a system controller unit for controlling the electrode arrangement at the cladding of the waveguide, wherein The cladding of the waveguide is made of at least one material with the optical properties of an anisotropic liquid, or of at least two materials with the properties of an isotropic liquid, The matrix arrangement of the control electrodes defines a multitude of positions to be generated for local output coupling points in the cladding of the waveguide, where the actually addressed control electrodes define a pattern of positions at which the total reflection is locally cancelled, and The system controller means is configured such to modify the positions of the output coupling points for superposing the output-coupled light through the lens array to at least one visibility region by displacing an output coupling point or by switching off one output coupling point and switching on another one.
