Abstract
A volumetric type three-dimensional display device can include a plurality of voxels having a polyhedron shape laminated three-dimensionally. A unit display panel in which an organic electroluminescent device and a polymer-dispersed liquid crystal device are laminated from the outside is configured on at least one surface of the polyhedron shape of the voxels.
Claims14
A volumetric type three-dimensional display device comprising:
- a plurality of voxels configured to display a three-dimensional (3D) image in a physical 3D space, each voxel among the plurality of voxels having at least three flat outer surfaces;
- and
- a plurality of unit display panels, each unit display panel among the plurality of unit display panels including:
- an organic electroluminescent device including at least one sub-pixel including an organic light emitting diode (OLED), and
- a polymer-dispersed liquid crystal device configured to have transparency for passing external light through the polymer-dispersed liquid crystal device and block the external light based on a voltage applied to the polymer-dispersed liquid crystal device,
- wherein each of the plurality of voxels includes one of the plurality of unit display panels disposed on one of the at least three flat outer surfaces of the corresponding voxel, and
- wherein the organic electroluminescent device is disposed at an outside of the one of the at least three flat outer surfaces of the corresponding voxel, and the polymer-dispersed liquid crystal device is disposed an inner side of the one of the at least three flat outer surfaces of the corresponding voxel in an area between a center of the corresponding voxel and the organic electroluminescent device.
