An optical device that produces flicker-like optical effects is provided. The optical device employs directionally cured image icons. Specifically, the optical device is made up of at least one arrangement of image icons formed from one or more cured pigmented materials, and at least one arrangement of optionally embedded focusing elements positioned to form one or more synthetic images of at least a portion of the arrangement(s) of image icons. Some or all of the pigmented material(s) is cured using collimated light directed through the focusing elements toward the arrangement(s) of image icons at one or more angles relative to a surface of the optical device to form directionally cured image icons. The synthetic image(s) of the directionally cured image icons is viewable at the cure angle(s) and therefore visually appears and disappears, or turns on and off, as the viewing angle of the device moves through the cure angle(s).

A display body includes a display surface including a plurality of display region groups. Each display region includes at least one reflection surface that is configured to reflect light incident on the display surface toward an area including a corresponding one of reflection directions that are associated with the respective display region groups. Each display region group is configured to form an image unique to the display region group in a corresponding one of the reflection directions through reflection of light on the reflection surfaces in the display region group. The display region groups are configured to form, in two adjacent ones of the reflection directions, different images that have a interrelation between each other.

A display medium comprises a flat member that reflects light, in which the flat member is divided into a plurality of unit cells, and each of the plurality of unit cells is divided into a predetermined number of subcells corresponding to a predetermined number of azimuth angles. Projecting members having a light-blocking surface are formed perpendicular to the flat member on top of the flat member and parallel to a predetermined azimuth angle in each subcell corresponding to the predetermined azimuth angle. The subcells include a plurality of microcells for expressing a color of the content

A tri-face artwork display device that allows for three different views within the same frame. One embodiment includes upper and lower rows of corresponding slits on the top and bottom of the frame. The slits have a predetermined depth so as to not penetrate through the other side of the frame. The slits hold the image panels that display the second and third image to compliment the first image. The image panel has a second image on its first face and a third image on its second face. Additionally, a clamshell provides enhanced depth to contents inserted within a frame. The clamshell includes a box assembly with sidewalls and a flap assembly that is insertable within a rabbet of a frame.

A display switching device according to one or more embodiments is disclosed. In a display switching device according to one or more embodiments, at least one of the pixel regions receives light from a plurality of light sources included in a predetermined light source group, and the light from each of the plurality of light sources is focused by a different lens.

Each protrusion surface has a shape of a strip extending in an extension direction perpendicular to the arrangement direction. Each protrusion surface tapers toward a top section in a thickness direction of an uneven structure. Each depression surface has a shape of a strip extending in the extension direction. Each depression surface tapers toward a bottom section in the thickness direction of the uneven structure. The protrusion surfaces and the depression surfaces are arranged at a period that limits reflection of light that is incident on the uneven surface in a front-view direction of the uneven surface and diffracts the light incident on the uneven surface to emit diffracted light in an oblique view direction of the uneven surface. The uneven structure has a property of absorbing light incident on the uneven structure.
