Abstract
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.
