Abstract:
In one embodiment, a modular multi-panel display system includes a mechanical support structure, and an array of LED display panels arranged in rows and columns and mounted to the mechanical support structure so as to form an integrated display. None of the LED display panels have a receiver card within the panel. A receiver box is mounted to the mechanical support. The receiver box is housed in a housing that is separate from housings of each of the LED display panels. The receiver box includes a receiver card coupled to feed data to be displayed on the integrated display to a plurality of the LED display panels. A control box is outside of the mechanical support and electrically connected to the receiver box through a data connection. A plurality of electrical connections electrically connects the receiver box with a first display panel in each row of display panels.
Abstract:
A transparent illuminated display system, typically for use in automobile race events, including a highly flexible and transparent PCB board with ultra-low profile LED's mounted to it. The flexible and transparent PCB boards can be in the shape of a single or multiple numeric or alphanumeric displays. The face of the display which would make contact with the face of a wind screen would include an adhesive element. The transparent illuminated display is mounted to a vehicle as a kind of sticker on the inside or outside of a racecar windscreen, back window and/or side windows. Each of the displays could be wired to power and data lines and illuminate the required numbers or text to show the position and other info of the car in the race.
Abstract:
A coordinated system of printed circuit board (PCB) assemblies for displaying information, such as advertising and pricing information. Each individual PCB assembly may display a unit price, such as a price for particular type of gasoline or other product. Each complete PCB assembly may have a number of Light Emitting Diode (LED) modules. The LED modules may be interconnected with one or more plug-in back panel modules attached to a housing and to power and control buses. The module housing may be interconnected with a main power supply and a controller. The controller may be configured to remotely and automatically change the price for each PCB assembly within the coordinated system. Each LED module may include a dedicated processor and be configured to have male connectors to plug into corresponding female receptacles on the power and control buses facilitating ease of installation, and replacement or repair of individual LED modules.
Abstract:
A directly addressable display device comprising at least one pixel cell (1-9), each pixel cell (1-9) being arranged for displaying a symbol, which symbol is repeatedly switchable between an on-state and an off-state, wherein each pixel cell (1-9) comprises an electrochromic layer (110) comprising an electrochromic and electrochemically active organic polymer material being electrochemically switchable between two different visually detectable coloring states; a counter electrode layer (140) comprising an electronically conductive material, wherein said counter electrode layer (140) in the viewing direction of the display device is arranged behind said electrochromic layer (110); an electrolyte layer (130), which electrolyte layer (130) is solid and arranged spatially between, and in ionic contact with, said electrochromic layer (110) and said counter electrode layer (140); a symbol defining layer (120) which is electronically and ionically insulating, arranged in direct ionic contact with said electrochromic layer (110), and which comprises one or more openings (121-129) which encloses said electrolyte layer (130) and defines the shape of said symbols; wherein said electrolyte layer (130) comprises a composition comprising a polyelectrolyte selected from one or more cationic polymers, wherein the electrolyte is substantially free of small cations.
Abstract:
A display device includes a light source and a light-transmissive display plate. The display plate is disposed at the light-emitting side of the light source. The display plate has an inner surface facing toward the light source and an outer surface facing away from the inner surface. The inner surface and the outer surface of the display plate each have a grain finish. The grain finish on the outer surface is finer in grain roughness than the grain finish on the inner surface.
Abstract:
A home appliance includes a front surface having an appearance. A transparent display is disposed on the front surface, and the display has an appearance that matches the appearance of portions of the front surface of the home appliance that are adjacent to the display. The display may be disposed (e.g., mounted) on the exterior of the front surface such that the front surface is visible through the transparent display. Alternatively, the transparent display may be disposed in or behind an aperture in the front surface of the home appliance. In this instance, a trim plate having an appearance that matches the front surface of the home appliance is mounted behind the transparent display, and the trim plate is visible through the transparent display.
Abstract:
Disclosed is a display device including a plurality of channels for forming a specific pattern, in which each of the channels includes: a light source module comprising one or more light sources for generating optical signals having different wavelengths; a driving module for controlling on/off or strength of the optical signal generated in the light source module; an optical waveguide for transferring the optical signal generated in the light source module to an outside without a loss of the optical signal; and a scattering pattern for scattering the optical signal transferred through the optical waveguide and displaying the scattered optical signal to the outside.
