A light-emitting display sheet includes a first fiber base material layer and a surface material layer stacked on the first fiber base material layer. The first fiber base material layer includes a first surface facing the surface material layer, and a second surface opposite to the first surface. The light-emitting display sheet further includes a print portion having an outline and sandwiched between the first surface of the first fiber base material layer and the surface material layer.

A color display device (D) is provided, including a colored light-transmitting base material (10), a light-blocking base material, and a light source unit (30) that has at least a part located between the colored light-transmitting base material (10) and the light-blocking base material (20), in which the colored light-transmitting base material (10) has a total light transmittance of 18% or less, and in which the light source unit (30) is disposed such that emission light transmits through the colored light-transmitting base material (10), the color display device having excellent designability and high luminance.

An illumination set has a plurality of alphabet lamps and a plurality of connectors. Two of the alphabet lamps are connected by one of the connectors. Each alphabet lamp has a bottom casing, a top cover, an illumination circuit board, and a slide. The top cover is mounted on the bottom casing. The illumination circuit board is mounted in the bottom casing and between the top cover and the bottom casing. The illumination circuit board has an illumination component and a plurality of sockets. The slide is detachably mounted on the bottom casing. The top cover is located between the slide and the bottom casing. A pattern is formed on the slide. Because the slide of the alphabet lamp is detachable, the pattern on the alphabet lamp can be changed.

Internally illuminable playing cards are disclosed. The disclosed playing cards may include a polymeric body, at least one light-emitting diode (LED) at least partially inside of the polymeric body, a battery (or a slot in the polymeric body for receiving a battery) for providing power to the at least one LED, and a switch at least partially inside the polymeric body and operatively connected to the at least one LED to facilitate turning the at least one LED on and off. As can be understood based on this disclosure, the internally illuminable playing cards can be used for flourishing and cardistry techniques, in a manner similar to the way typical paper playing cards are used for such techniques.

Aspects of the present disclosure include backlit graphical display systems that include an optically transmissive layer having one or more static images printed thereon for display, and a display located behind the optically transmissive layer. The display can be configured to colorize specific regions of the static images resulting in a backlit display having a very high resolution static shape with dynamic color and light intensity capability.

An emblem assembly is provided that includes a power source, a backing member, and a light-producing assembly coupled to the power source and supported by the backing member. The light-producing assembly may include an electroluminescent light source. The emblem assembly further includes a chromatic layer over the light-producing assembly that comprises and emblem shape, and a translucent sealing structure over the chromatic layer that seals the backing member, the light-producing assembly, and the chromatic layer. The emblem assembly exhibits a chrome- or mirror-like finish when viewed under ambient lighting conditions. Further, the emblem assembly possesses a glowing appearance when activated under low light or nighttime conditions.

A lighted display for mounting upon a vehicle having a trailer hitch receiver. The lighted display includes an elongated base member with a trailer hitch mount affixed midway along the base member. The base member also incorporates a horizontal step plate extending outward from upper edge of the base member allowing easier access to the rear of the vehicle. The base member is configured to receive multiple lighting elements within an elongated vertical channel. The lighting elements are connected to a trailer wiring plug which is configured to engage the vehicles trailer wiring connector. A message board is positioned within the vertical channel of the base member. The message board is made of a semi-translucent material which allows a portion of the light from the lighting elements to pass. The message board is partially masked with an opaque material, the unmasked portions forming the desired message for display. Upon illumination of the vehicle driving lights, one or more of the lighting elements are illuminated at the low light intensity level. Upon illumination of the vehicle brake light, one or more of the lighting elements are illuminated at the high light intensity level. And upon illumination of the vehicle turn signal light one or more of the lighting elements are illuminated at the high light intensity level in coordination with and on the corresponding side of the vehicle as the vehicle turn signal light.

A display device is provided. The display device includes: a first display panel and a second display panel; and a backlight between the first display panel and the second display panel, wherein the backlight includes at least one Printed Circuit Board (PCB), and a plurality of Light Emitting Diodes (LEDs) arranged on different faces of the PCB and configured to supply light to both the first display panel and the second display panel located on different sides of the backlight.

A display apparatus includes plural light source units each including a light emitting device and a lens portion; a reflection sheet defining plural holes thereof and into which the light source units are respectively disposed; and a display panel on the reflection sheet. The lens portion defines: a body portion; and plural side protruding portions and respectively at opposing sides of the body portion in a first direction in a top plan view. The hole of the reflection sheet is defined by: an edge of a first hole; an edge of a second hole facing the first hole in a second direction crossing the first direction, the second hole larger than the first hole; and slanted edges connecting the first hole to the second hole. In a fixed state of the reflection sheet, a predetermined area of the reflection sheet adjacent to the slanted edges overlaps the side protruding portions.
