Abstract:
An assembly for cooling an electronic image assembly having a rear channel placed behind the image assembly and a heat exchanger for accepting ambient air. The system contains a first fan placed within the heat exchanger to force ambient air through the heat exchanger and the rear channel. A second fan may be used to force circulating gas through an interior portion of the display housing and through the heat exchanger in order to transfer heat to the ingested ambient air.
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 flat panel display (10) having a black mask EMI layer isolated (32) from Vcom and tied to zero potential. The flat panel display (10) has an integral metal heater layer (34) and thermal sensor (82) that are in close proximity to the liquid crystals (14) to provide efficient heating and temperature sensing.
Abstract:
A touch panel (110) is integrated into a flat panel display device (180) having a visual display surface with a front polarizer layer (160), particularly a liquid crystal display device (180). The touch panel (110) comprises a flexible transparent membrane containing the front polarizer layer (160) and having a first transparent conductive layer (134) on a lower surface of the flexible transparent membrane and a rigid base (120) comprising the flat panel display device (180) and having a second transparent conductive layer (124) on an upper surface of the rigid base (120). At least one spacer (40B) separates the flexible transparent membrane from the rigid base, keeping the first and second transparent conductive layers in spaced-apart facing relationship. A bus bar (44) and tail (46, 48) communicate a signal from the touch panel to the flat panel display device (180).
