A self-contained illuminated sign for mounting on a vehicle is disclosed. The sign includes a front panel, a rear panel situated opposite and substantially parallel to the front panel in spaced relation therefrom to define a space therebetween, and a light source comprising a plurality of LEDs. The light source is positioned between the front and rear panels and is configured to emit light that emanates from the front panel. The front panel is thus backlit to display indicia. A system for supporting a self-contained illuminated sign on a vehicle is also disclosed. The system includes the sign and a separate mounting frame mountable on a vehicle. The mounting frame is configured to removably receive the sign and, when the sign is received in the mounting frame, to surround a perimeter of the sign while permitting visibility of the front display area. Related methods are also disclosed.

A display medium displays a predetermined number of contents corresponding to a predetermined number of azimuth angles when viewed from a predetermined elevation angle and azimuth angle. An example display medium includes: a planar member that reflects light; and a plurality of protruding members, each protruding member of the plurality of protruding members has a surface occluding the light, placed vertically on the planar member and parallel to each of the predetermined number of azimuth angles. The planar member is partitioned into a plurality of unit cells, where each unit cell is further partitioned into the predetermined number of sub-cells corresponding to the predetermined number of azimuth angles. The protruding member that has the surface parallel to the predetermined azimuth angle is formed for each sub-cell corresponding to the predetermined azimuth angle.

A display apparatus includes a display panel supported within a case having a rear surface including a circular recessed portion. An annular total reflection mirror and an annular half mirror are disposed in the circular recessed portion with an annular light source provided therebetween. A pattern forming member is disposed on an outer side of the annular half mirror and is configured to be reflected by the annular total reflection mirror. A pattern light source is configured to supply light to the pattern forming member so that the pattern is reflected on the annular total reflection mirror. When the annular light source and the pattern light source are turned on, the pattern of the pattern forming member is reflected between the annular total reflection mirror and the annular half mirror.

A consumer appliance, a provided herein, may include a cabinet and a user interface disposed on the cabinet. The user interface may include an external panel, a control board, a touch sensor, a reflector plate, and a light source. The external panel may include an outer surface facing outward and an inner surface positioned opposite from the outer surface. The control board may be positioned behind the external panel and include a forward surface facing the external panel and a rearward surface facing away from the external panel. The control board may define a light aperture extending therethrough. The touch sensor may be mounted on the control board and spaced apart from the forward surface. The reflector plate may be spaced rearward from the control board to define an open region. The light source may be mounted on the control board at the rearward surface and face rearward.
