Abstract: A floating image display device includes: an image forming device configured to form a source image; a waveguide configured to output a light of the source image to another location by guiding the light; a holographic optical device provided on a proceeding path of the light output from the waveguide, the holographic optical device including a hologram pattern that diffracts incident light of a certain incident angle region output from the waveguide by a set target diffraction angle and a floating element including a plurality of corner reflectors and forming a floating image of the source image by forming an image of the light output from the holographic optical device at a certain location in mid-air.

Abstract: Disclosed are a display device and a display panel including a substrate, a first subpixel array including first subpixels arranged in a first region on the substrate, a second subpixel array including second subpixels arranged in a second region on the substrate, and a third subpixel array including third subpixels arranged in a third region on the substrate. The first region, the second region, and the third region are spatially separated and provided side by side on a same surface of the substrate. The first subpixels are grouped by a first primary color and are patterned as the first subpixel array in the first region. The second subpixels are grouped by a second primary color and are patterned as the second subpixel array in the second region. The third subpixels are grouped by a third primary color and patterned as the third subpixel array in the third region.

Abstract: A projecting device includes a light source configured to output an image light; a projection lens configured to externally project the image light; a camera configured to photograph an object positioned between the camera and an external projection surface of the image light that is projected; a light blocker configured to block the image light output by the light source during a blocking period; and at least one processor configured to: obtain illuminance information regarding illuminance of the external projection surface, set the blocking period during which the image light output by the light source is blocked, based on the illuminance information, set a photographing period within the blocking period, control the light blocker to block the image light output by the light source during the blocking period, and control the camera to photograph the object during the photographing period.
