An electronic price and/or product display device (2), which comprises a reflective screen (21) for displaying information, and a signalling device (28) for signalling an internal state or a state change of the display device (2) by superimposing said state or state change in a visually perceptible manner directly in the viewing direction of the screen.

A light-emitting display device includes: a light-emitting member; and a light-blocking layer-equipped fiber sheet that covers a light-emitting surface of the light-emitting member. The light-blocking layer-equipped fiber sheet includes a fiber sheet, and a light-blocking layer that is partially printed on at least one surface of the fiber sheet. The surface of the fiber sheet on which the light-blocking layer is formed has an arithmetic mean height Sa of 3 to 20 μm, as measured based on ISO 25178, and the fiber sheet has an apparent density of 0.5 g/cm.sup.3 or more.

A trim element having an outer surface that is at least partially translucent, the outer surface defining a main display surface and a peripheral display surface, the peripheral display surface extending around at least a portion of the main display surface, a screen of a display device extending opposite the main display surface. The trim member includes an illumination device having a luminous sheet extending opposite the main display surface and the peripheral display surface so as to emit at least a first luminous signal onto the screen and at least a second luminous signal illuminating at least a portion of the peripheral display surface when the luminous sheet is activated.

A trim element having a display area defined by a display device, and an edge piece that includes a peripheral area extending around at least part of the display area, the peripheral area being at least partly translucent, the display area and the peripheral area forming at least a part of an outer surface of the trim element. The trim element further includes an illumination device arranged to illuminate the display device to display images on the display area. The illumination device has a luminous sheet extending at least facing the display area and the peripheral area of the edge piece.

An illuminated flag, the flag includes a first layer of flag, a second layer of flag and a spacer separating the first and second flag layers to form an optical cavity between the first and second flag layers. A light source is contained within the optical cavity to illuminate the first and second layers. A light distribution element between the light source and layers of the flag distributes the light uniformly upon the inside of the layers. This illumination from within the flag provides a substantially uniform glow to the exterior of the flag. The flag can be supported by a standard flag pole and is able to move in a breeze.

A display module comprises light-emitting elements coupled to one or more mounting structures and grouped into a pixels in a pixel array on a display face to display textual, graphical, or video information, with each pixel comprising a grouping of one or more light-emitting elements. A face cover is mounted to the mounting structure and is positioned in front of at least a portion of the display face. The face cover comprises a plurality of moguls arranged in a mogul array with each mogul positioned in front of and proximate to a corresponding one of the pixels so that the mogul covers at least a portion of the corresponding pixel, and one or more light-emitting openings in each mogul, each positioned relative to one or more corresponding light-emitting element of the pixel to permit light emitted from the corresponding one or more light-emitting elements to pass through the mogul.

Self-contained devices, systems and methods for housing holiday lights in the form of icicles, and the like, in self-contained boxes that can easily be mounted and removed around house windows and eaves. The lights can be retractable and extendable downward from the boxes, and the lights can be remotely controlled by smart phones and the like. The boxes can have displays for holiday messages as well as speakers for playing music and messages. Another embodiment can include a drop down version where the lights drop down from a housing. Another version can include a fold out version where a support frame having upwardly protruding lights is rotated so that the lights extend below the housing.

A light-transmitting assembly of a display device, a signal indicator, and the display device are provided in the embodiments of the present disclosure. The light-transmitting assembly of the display device includes: a light-transmitting adjustment member including a plurality of first patterns, a light transmittance of each first pattern is less than a light transmittance of a region of the light-transmitting adjustment member other than the first pattern, and each light-shielding area ratio of the first patterns is a ratio of a sum of areas of all the first patterns in any one region of the light-transmitting adjustment member to an area of the any one region.

Light emitting diode (LED) light tubes having rotatable end cap assemblies are described. The LED light tubes include a hollow tube and a circuit board with LED chips thereon. The end cap assemblies are provided on either end of the tube. Each end cap assembly includes a socket cap, a plug having a plug body and at least one connector, and an end cap body, one end of which engages one of the ends of the hollow tube. A cam locking mount that is positioned within the plug body and on the opposite side has projections to be positioned in the bore of the end cap body. A rotation cam is seated in the cam locking mount and provides for controlled rotation of the LED tube relative to the end caps. Methods of installing the LED light tubes in new installations and retrofit installations and for use in sign assemblies are also described.

Provided here are mobile way-finder signs having changeable panels that are internally illuminated. Internal illumination may be caused by battery-powered LED light bulbs. The sign may include a base, an inner frame, an outer frame, a changeable panel, and a retainer. The sign may include a power toggle switch and interior LEDs and wiring within the inner or outer frames. The sign may include a rechargeable battery pack located under the base in a snap-in holder, and heavy-duty black polyurethane wheels.
