A modular distributed control LED display system, comprising several LED display module units (100) which are spliced together to form an integrated LED display screen, each of the LED display module units (100) comprises a lamp board (110) and an independent controller (120), wherein the lamp board (110) is provided with a number of LED light sources, and the independent controller (120) is provided on the back of the lamp board (110), the independent controller (120) is used to control the working state and display mode of the LED light sources.

A display device includes a display panel, a backlight assembly, a back cover and a curve control assembly. The back cover has a curved shape and faces the display panel with the backlight assembly therebetween to cover a back surface of the backlight assembly. The curve control assembly is between the backlight assembly and the back cover to adjust a curved degree of the display panel. The curve control assembly includes a first rail, a second rail, and a rolling unit. The first rail is coupled to the back surface of the backlight assembly, and the second rail is coupled to the back cover to face the first rail. The rolling unit is commonly connected to each of the first rail and the second rail and is movable along the first and second rails to move the display panel in directions toward and away from the back cover.

An integrated lighting system to efficiently manage battery life with indoor and outdoor modes by charging a battery during the day, turning on lights at peak night hours, and protecting the battery from overvoltage/leakage. The system comprises circuitry operable to connect to the battery and the LED light sources, the circuitry comprising a solar cell, a timer circuit, and a protection circuit. The solar cell charges the battery during daylight hours. The timer circuit regulates time periods during the day to turn on the LED light source. The overcharge circuit prevents damage from possible overcharge/leakage.

A light-emitting sign comprising a light source for emitting light, in which the light-emitting sign may be thin (e.g., comparable to a conventional non-light-emitting sign) while creating a desired visual effect using the light emitted by the light source. This may be achieved, for example, by the light source being thin itself and/or by having an external device connected to the light-emitting sign and implementing certain functionalities (e.g., powering and/or controlling the light source).

An insect trapping light is shown having a visible light housing, an electronic display screen, and an insect trapping housing. The display screen may be a television screen, picture display screen, movie display screen, computer monitor or display, or the like. The insect trapping housing has a bottom space configured to removably receive an insect bait tray that may be filled with an insect baiting substance to attract insects. The insect trapping housing and the visible light housing combine to form a UV light space or chamber therebetween. An adhesive board is slidably received and held in place upon the visible light housing surface facing the UV light chamber. The spacing between the insect trapping housing and the visible light housing defines the UV light chamber having open sides The UV light chamber also includes a matrix or array of UV lights or light sources.

Systems, kits and methods are disclosed which facilitate more dynamic and visually impactful backlighting of fabric panel displays. A perimeter frame assembly has a front edge, a rear edge, and a backlight cavity disposed therebetween. A front perimeter groove extends along the front edge. A display panel includes a flexible textile display substrate removably mounted in tension across the backlight cavity. A planar array of independently-activatable point light elements distributed in mutually-orthogonal X and Y directions is disposed within the backlight cavity at a gap distance from the display substrate. The gap distance is orthogonal to the X and Y directions. A controller is in data communication with the planar array for programmably controlling sequential activation and deactivation of the point light elements independently of one another. The display substrate may have a dye sublimated printed textile graphic thereon, and the point light elements may be white LEDs.

The present invention relates to a modularized spliced LED display screen including a plurality of unit screens. When assembling, a certain number of the unit screens are assembled in a splicing frame to form a module screen. A number of the said module screens are assembled horizontally to form a large display screen. The present invention forms a module screen by a plurality of unit screens of the same structure, and then assembles a plurality of module screens horizontally to form a large display screen, and the overall assembly method is simple, and is easy to assemble and disassemble.

A hybrid photoluminescent display consumes little electrical power and provides for light emission/color in a desired color. The display includes a housing having openings forming a desired legend. White LEDs internal to the housing provide light for energizing photoluminescent material. A legend panel housed within the housing defines openings corresponding to the legend. Photoluminescent material is disposed within the openings of the legend panel. The photoluminescent material is selected to be energizable by light from the white light source, and to emit light primarily in a selected wavelength range corresponding to a desired legend color. A color is filter disposed adjacent the photoluminescent material on a side of the legend panel opposite the light source. The color filter is selected to selectively transmit substantially all light in the selected wavelength range, and to selectively not transmit substantially all light outside the selected wavelength range.

Field serviceable display assemblies are provided. Multiple side assemblies are mounted to a structural framework in a moveable manner, each including a channel located between a transparent layer and an electronic display, which is located behind the transparent layer. A fixed structure is positioned within a cavity located within the structural framework and between the side assemblies. The fixed structure remains stationary when the side assemblies are moved between a closed position where the cavity is enclosed, and an opened position where the fixed structure is exposed to facilitate direct access to electronic components located thereon.

A product display shelf, system and method are disclosed. The product display system includes a shelf unit having a back shelf portion and a front shelf portion. The back shelf portion includes a first connecting element for releasably attaching the back shelf portion to an electrically powered support member, and the front shelf portion includes a second connecting element for releasably attaching the front shelf portion to the back shelf portion. The front shelf portion can also include a body portion and a display panel connected to or integral with the body portion, suitable for displaying information to a user.
