Abstract:
A multi-angle attachable display device includes a polygonal light emitting module and a control module. The light emitting module has a light emitting layer with at least one light emitting unit, a module driver, and multiple connection ports. The at least one light emitting unit includes a unit driver that electrically connects the module driver. Each of the connection ports is mounted on a side surface of the light emitting layer and electrically connected to the module driver. The control module includes a controller connection port, a wireless communication unit, and a processing unit. When the controller connection port is connected to one of the connection ports of the light emitting layer, the processing unit detects a connection pathway of the light emitting module, and the processing unit generates and sends a light pattern signal to control the unit driver through the controller connection port and the module driver.
Abstract:
An illuminated display for displaying a lottery jackpot values in the range of millions and billions of dollars is disclosed. The lottery display has an LED array for selectively displaying either “MILLION” or “BILLION.” A special LED module for representing an uppercase letter “M” or uppercase letter “B” is positioned next to a series of LED elements configured to display “ILLION.” A special LED module having nine segments may be employed for the indicia of units, where the LED module may be illuminated to form the numerals 0 through 9, as well as an upper case letter “B.” The illuminated display may also display indicia for currency and the day of the week for the jackpot draw.

Abstract:
A manufacturing method of filling a resin into a housing includes the steps of: providing a housing that has at least one recess, with the recess having first and second spaces, and the first space being disposed above the second space; inverting the housing; injecting a fluid into the recess to fill the first space, with the fluid having a viscosity coefficient and a surface tension less than those of water; and injecting a first resin into the recess, with the first resin having a specific gravity greater than that of the fluid, such that the first resin fills the first space and the fluid fills the second space.
Abstract:
This invention relates to a drone, method and systems for displaying messages and/or images by using a group of one or more remotely controlled airborne drones provided with display means and controlled so the messages and/or images are created and are visual by the display means of the group of airborne drones. The display means are controlled such that the messages and/or images are 2D or 3D respectively. The display means may include LED's, OLED's or LCD based on means or DLP and/or laser projection means. The display of messages and/or images can be remotely controlled using a social gateway for airborne visualization, enabling the integration of content from end-user and marketing clients based on the drone's geographic position and social media audience profile.
Abstract:
A modulator can include a common signal modulator that outputs a predetermined number of common signals to a multiplexer interface liquid crystal display (MUX LCD) based on an output state of a set of general purpose input/output (GPIO) pins of a controller, wherein each common signal has at least four bias levels. The modulator can also include a segment signal modulator that outputs a predetermined number of segment signals to the MUX LCD based on an output state of another set of GPIO pins of the controller, wherein each segment signal has at least three bias levels.
Abstract:
A display assembly comprising a first display member and a second display member, wherein the first display member is at least partially superimposed upon, fixed to and rotated with respect to the second display member and the first and second display members can be selectively actuated.
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 method includes providing access to a multi-panel display including a plurality of display panels. Each panel of the plurality of display panels is mounted onto a mechanical support structure. The method further includes identifying a defective panel from the plurality of display panels. Without powering down the multi-panel display, electrical connection to the defective panel is disconnected and the defective panel is removed from the mechanical support structure. The method also includes attaching a replacement display panel to the mechanical support structure at the location of the defective panel, and connecting power to the replacement display panel. One or more of the remaining of the plurality of display panels continue to display during the time the defective panel is disconnected and removed, and the replacement display is attached.
