Curtiss-Wright Controls Introduced Family of Rugged High Definition Dual LED Backlit Displays
Sep 29, 2011 Curtiss-Wright Controls Embedded Computing (CWCEC), a business group of Curtiss-Wright Controls and a leading designer and manufacturer of commercial off-the-shelf (COTS) VME, and OpenVPX(TM) products for the rugged deployed aerospace and defense market, has announced the availability of its new enhanced family of Skyquest(TM) rugged displays for use on airborne platforms. The new family of Dual LED Backlit Skyquest Displays, available in configurations from 10.4" to 20", provides a unique way of delivering Night Vision Goggle (NVG) filtering, and features LED illumination with wider color range, less heat dissipation and less light performance degradation than experienced with older cold cathode tube displays.
Traditional NVG filtering is achieved by fitting a filter to the full display area, which dims the image and adds an undesirable green tint that is visible in both daytime and nighttime operations. With CWCEC's Dual LED Backlit Skyquest Displays, this filter is removed from the front of the screen. Instead, the filtering occurs in the backlight located behind the LCD. A simple toggle switch enables the selection of either white daylight LEDs or green NVG-filtered LEDs integrated in the backlight within the display, providing complete control over the type of light emitted from the screen. The result is a very high brightness, full color image readable in direct sunlight during daytime operations, and a fully filtered display ideal for NVG operations.
The new LED displays provide a number of significant advantages over older cathode tube technology. Because they use solid state devices instead of glass tubes, the LED displays are much more rugged as issues associated with the mounting of glass tubes and shock breakage are eliminated. LED displays, which offer highly precise brightness control, enable the system integrator to create different lighting regimes for different application areas.
The new LED dual lit displays will be commercially available in Q2 2011.
