摘要： A resistive touch panel assembly is disclosed. An optical stack located within a housing includes an electronic display layer adapted to display an image and a resistive touch panel. A number of touch input receivers are placed adjacent to a first and second independently operable, grid sections which are located adjacent to one another in a seamless fashion. A number of input/output devices are in communication with the optical stack and extend through a channel comprising shielding.

摘要： A backlight assembly includes a substantially planar light guide defining an upper, lower, and first side surface. A first plurality of LEDs is positioned to emit light into the lower surface. A NVIS filter is placed adjacent to, and a second plurality of LEDs is positioned near to, the first side surface. A directing element extends between the second plurality of LEDs and the NVIS filter and directs the emitted light from the second plurality of LEDs through the NVIS filter and into the light guide. The NVIS filter extends substantially perpendicular from a support structure associated with the light guide.

摘要： A system for detecting errors in a source driver for an electronic display includes an upstream logic device, a comparator, and a source driver. The source driver has a number of driven channels which transmit active signals for generating an image on the electronic display and one or more dummy channels which transmit dummy signals to the comparator. The comparator receives and compares signals from at least some of the driven channels with the dummy channels and generates an alert for transmission to the upstream logic device if a mismatch is detected.

摘要： A backlight device for a liquid crystal display containing a substantially planar light guide with a light emission surface and a light-collecting portion opposing the light emission surface. A pair of opposing side portions may define the periphery of the light guide. A first plurality of LEDs are placed so as to direct the emitted light into the light-collecting portion. An NVIS filter is preferably placed adjacent to at least one of the side portions. A second plurality of LEDs are placed to direct the emitted light through the NVIS filter and into a side portion of the light guide. Alternative embodiments can contain NVIS filters and LEDs along additional edge portions of the light guide. Some embodiments may use directing elements or slanted surfaces of the light guide to direct the light from the second plurality of LEDs into the edge portions of the light guide.

摘要： In an exemplary embodiment, each horizontal and vertical conductor of a TFT array may be in electrical contact with a first and second control system. Initially, the entire display is driven by the first control system. When/if a failure occurs in the first control system, it is powered down and the second control system maintains operation of the entire display. Each control system may contain a set of source/gate drivers, display interface board, and power supply. A reversionary button may allow the user to manually switch between control systems. Alternatively, failure may be detected by the display interface boards or a graphics processor.

摘要： An electronic display assembly includes a display layer for displaying an image, a projected capacitive touch panel with touch input areas, each of which are independently operable and configured to receive touch input from a user. Input/output devices are electrically connected with the display layer touch panel. Software instructions, when executed, configure one or more processors to automatically begin utilizing a remaining operable input/output device if one of said input/output devices is rendered inoperable.

摘要： A projected capacitive touch panel is placed above an electronic display and the assembly is housed in a sealed gasket. The touch panel has at least two touch sensors and at least two receivers per touch sensor, each in communication with an input/output device and in communication with a series of receivers. The touch panel comprised of electronic circuits configured to minimize electromagnetic interference. The electronic display comprised of multiple layers configured to provide visibility in bright ambient conditions.

摘要： A backlight assembly includes a substantially planar light guide defining an upper surface, a lower surface, and a side surface. A first plurality of LEDs is positioned below the lower surface of the light guide and oriented to direct the light emitted therefrom into the lower surface. A NVIS filter is placed adjacent to the side surface and a second plurality of LEDs is positioned near the side surface. A separating element extends between the first and second plurality of LEDs. A directing element extends between the second plurality of LEDs and the NVIS filter to direct the emitted light from the second plurality of LEDs through the NVIS filter and into the light guide.
