Abstract:
Exemplary embodiments include a backlight assembly for a display wherein the backlight assembly is comprised of a plurality of tiles. Each tile has a plurality of lights attached to it, such that when a single light or group of lights fail, the tile may be replaced without having to replace the entire backlight assembly. The current draw and/or illumination of each tile is calibrated and maintained throughout the life of the display to ensure a uniform distribution of light across the backlight assembly.
Abstract:
Exemplary embodiments provide a durable anti-reflective display panel for an electronic display. The panel may be used with any flat panel display including but not limited to LCD, plasma, and organic LED displays. Embodiments may contain anti-reflective glass and a linear polarizer. Some embodiments contain pyrolytic coatings and may be bonded together using an index-matched optical adhesive. Exemplary embodiments can resist impact from objects at high speeds and protect the electronic display from damage. In some embodiments the pyrolytic coating is electrically conductive and can be connected to a power source for heating the display panel and/or controlling condensation.
Abstract:
Exemplary embodiments provide an information system adapted to focus a plurality of audio messages to a plurality of different locations. As a consumer passes a display, their attention is attracted based on the series of messages. Further, a consumer can obtain more and different information as they change their position. Exemplary embodiments may also display a different image to the consumer depending on the position of the consumer relative to the display. Further embodiments may utilize touch-screen technology to allow a user to select an icon from the screen and obtain further information either through additional messages, video, or both.
Abstract:
A cooling assembly for an electronic image assembly and a display assembly containing the same. Some embodiments use ambient gas to cool power modules and/or an image assembly (sometimes backlight). Other embodiments use a closed loop of circulating gas which passes across the front surface of an image assembly and through a heat exchanger. An open loop passes through the heat exchanger and extracts heat from the circulating gas. Ambient air may be used as the ambient gas. An optional additional channel may be used to cool the back portion of the image assembly or backlight with ambient gas. Some embodiments also use thermally conductive plates and ribs to distribute the heat and avoid hot spots in the display. The cooling assembly can be used with any type of electronic assembly for producing an image.
Abstract:
Exemplary embodiments provide a system and method for securely transmitting video data to an electronic display. The video data may be transmitted using a wired or wireless application. Raw video data is encoded as a plurality of JPEG frames. A plurality of packets are created which may contain one frame or a portion of a frame of video. Each packet contains a unique header with information about the packet and a unique security key. After transmission each packet may be analyzed to determine if it was the intended transmission. The packets are re-assembled and displayed if they are the intended transmission. A default image or video is displayed if the received transmission is not the intended transmission. If a single packet is missing or is unintended, the previous packet may be repeated. Additional standard wireless encryption may also be used if utilizing a wireless application.
Abstract:
Exemplary embodiments include a backlight assembly for an electronic display wherein said backlight assembly is comprised of a plurality of tiles. Each tile has a plurality of lights attached to it, such that when a single light or group of lights fail, the tile may be replaced without having to replace the entire backlight assembly. The lights in the assembly may be any one of the following: light emitting diodes (LED), organic light emitting diodes (OLED), field emitting display (FED), light emitting polymer (LEP), and organic electro-luminescence (OEL). Embodiments also allow tiles to be removed from the rear of the display and dissipate heat from the lights to the rear of the backlight assembly.
Abstract:
Embodiments relate generally to various thermal control features for electronic displays. One feature comprises a closed loop isolated gas chamber, where a first chamber is in contact with the display surface and transfers heat between the isolated gas and the display surface. A second chamber is in gaseous communication with the first chamber and is adapted to heat or cool the isolated gas and reintroduce the isolated gas into the first chamber. Another feature uses constricted convection to facilitate the cooling of the backlight assembly for the electronic display. Another feature uses an air curtain to further heat or cool the exterior viewing surface of the display. Another feature uses a linear polarizer with an insulating gap to reduce the solar loading of the display stack and provide insulation from the ambient air temperature. Another feature uses a fluid system to contact fluid coolant with the display surface in order to cool the display. Each of the features may be used alone, or in combination to provide the proper operating temperature for the display depending on its desired operating environment.
Abstract:
A flat panel display, particularly a liquid crystal display has a front plate with a plate area defined by a plate perimeter, which is in turn defined by a first and second pair of parallel sides, the pairs of sides in perpendicular relationship to each other. An active display area providing a unitary visual display is located within the plate perimeter. In the invention, this active display area is divided into at least first and second display areas, a visual output of said first and second display areas being separately driven. In some embodiments, one or both of the display areas is subdivided into first and second subdisplay areas, with the visual output of the first and second subdisplay areas being separately driven.
Abstract:
A system for displaying content on multiple electronic displays utilizing a single video player and transmitter. Some displays may show dynamic video and the remaining displays may show static images. Alternatively, every display may be showing static images. The player provides frames of video which may be encoded with unique display identifiers which direct the system to display the proper frames on the proper displays. The transmitter may be in wireless or hard-wired electrical communication with the display receivers. If using a hard-wired embodiment, the displays may be daisy-chained together to reduce the length of wire/cable needed.
Abstract:
A flat panel display having a black mask EMI layer (58) isolated from Vcom (62) and tied to zero potential. The flat panel display has an integral metal heater layer (70) and thermal sensor (82) that are in close proximity to the liquid crystals to provide efficient heating and temperature sensing.
