A system includes at least one light pipe, at least one light source disposed at least partially within an interior of the system, a lens substantially enclosing the interior, the at least one light pipe, and the at least one light source, the lens having a continuous transparent or translucent coating on the outer surface, with the at least one light source receiving electrical power from the electrical power source, the continuous transparent or translucent coating being at least partially permeable to at least some light which is emitted by the at least one light source and passed through the lens, and at least one mask located between the at least one light pipe and the lens, a plurality of small contact areas being provided on the outside or inside of the light pipe or on the mask.

An LED sticker is disclosed that receives an NFC transmission from a nearby smartphone to energize LEDs in the sticker. A spiral (or loop) antenna is used in the sticker to generate power from the NFC transmission. The NFC signal is at 13.56 MHz, which is the resonant frequency of the NFC antenna circuit in the smartphone. The LED portion is formed by sandwiching pre-formed microscopic LEDs between two conductive layers to connect the LEDs in parallel. The conductive layers form a relatively large integral capacitor that is used to achieve the 13.56 MHz resonant frequency. So no additional capacitor is needed in the circuit to achieve a resonance of 13.56 MHz. This greatly reduces the design requirements of the antenna. The LED sticker may also contain an NFC tag having its own independent loop antenna and NFC chip. Various practical applications of the LED sticker are disclosed.

There is provided a display apparatus, including: a display module; a first side frame and a second side frame on two sides of the display module in a width direction of the display module; a fixing structure on a non-light-emitting side of the display module and detachably connected to the first side frame and the second side frame, the fixing structure being configured to fix the display module; and an adapter, including a first connection part and a second connection part which are fixedly connected. At least one of a first side surface of the first side frame facing the display module or a second side surface of the second side frame facing the display module is detachably connected to the first connection part, and the second connection part is detachably connected to the fixing structure.

A display unit has a base with a base plate, a set of reflectors and a transparent or translucent cover. The base plate has an array of openings. Each opening is sized to receive a light socket from a string of lights and hold the light socket. There is one reflector for each opening in the base plate positioned adjacent a respective opening in the base plate and against the front surface of the base plate. A transparent or translucent cover is positioned over the set of reflectors and connected to the base. Two or more display units can be connected together side by side, parallel or at an angle to one another to create displays having different heights, different widths, and different shapes. The user can easily create letters, numbers, symbols, icons or pictures through the choice and positioning of lights having different colors in the display units.

According to the present invention, there is provided a display apparatus (D) having a colored light-transmitting base material (10), a black light-transmitting member (56) containing a black colorant, and a light source unit (40), in which the light source unit (40) is disposed such that emission light of a light source is transmitted through the colored light-transmitting base material (10) and the black light-transmitting member (56) in this order, a total light transmittance (T) of a layer obtained by combining a layer of the colored light-transmitting base material (10) and a layer of the black light-transmitting member (56) is 13% or less, and the black light-transmitting member (56) has an L* value of 45 or less. The display apparatus (D) has excellent designability and high luminance.

Disclosed are various embodiments of a mobile advertising display apparatus. In one example, among others, the apparatus can include a display enclosure that includes a first side, a second side, a front side, and a back side. The first side can have a slot, and the back side can have an aperture that enables for a manipulation of content to be moved through the slot. The apparatus can include a flexible connector that has a first end and a second end. The first end can be attached to the back side of the display enclosure and a clamp can be attached to the second end of the flexible connector.

A display device is disclosed. The display device includes a base display panel, a back cover supporting a rear portion of the base display panel, sliding frames sliding with respect to the back cover, a driving unit configured to drive the sliding frames to slide, and a rollable display panel being extendable in response to the sliding of the sliding frames. The rollable display panel can be extended as needed by a user when widescreen images are displayed.

The purpose of the invention is to realize the display whose screen is seen as floating in the transparent medium. The present invention, for example, takes a following structure. A display device including a transparent display device being fixed in a pedestal including: the transparent display device having a display area and a first transparent medium, the first transparent medium existing between the display area and the pedestal, in which scanning lines and video signal lines are formed in the display area, scanning line lead wires and video signal lead wires are formed in the first transparent medium, and provided an area of the display area is S1, and an area of the first transparent medium is S2, S2/S1 is 0.5 or more.

Magnet signage lighting systems are disclosed in which electricity and informational data are transferred from wiring extending from an electrical power source to one or more electrical connector members. At least one power source magnet is electrically connected to the connector member or members. Signage lighting members have lighting member magnets affixed thereto such that when the lighting member magnet is attracted to and connected to the power source magnet, electricity and informational data is transmitted from the power source and an informational data controller, through the connector member or members, to the power source magnet, and then to the lighting member magnet to illuminate and provide informational data to the signage lighting members.
