VertexLCD NVIS LCD
Size: 5.0″ (640 x 480), 10.4″ (1024 x 768)
On May 14, 2008, VertexLCD announced two TFT LCDs that feature Night Vision Imaging System (NVIS) compliant LED backlight systems. Both LCDs meet NVIS Mil-3009 Type I or Type II NVIS standards and feature high brightness for use in bright ambient conditions and NVIS filters for low light applications. Possible NVIS applications include: military aircraft cockpits, tanks, trucks, ground mobile applications, etc.
I’m not a military expert so the term NVIS is new to me. Let’s dig in a bit. NVIS requirements are covered by MIL-L-85762A and MIL-STD-3009. NVIS displays for cockpit applications have the following trends: wide viewing angles for cross cockpit viewing and multiple display.
As you can see from the picture above, the cockpit of a Gulfstream C-37 contains no less than 8 square LCDs that must be easily viewable in direct sunlight (look at the bottom two LCDs that are in direct sunlight). Some of the main features of NVIS requirements include: black on the display must appear black when using NVG goggles, reflections must be minimized from LCD glass, the red primary color must be solid when in NVIS mode.
With the LED backlight power consumption is reduced, lifetimes are increased and reliability is enhanced: critical features for military applications. VertexLCD will showcase the NVIS compliant LCDs at the upcoming SID International Symposium.
