ABSTRACT:
A full color, night vision goggle compatible, liquid crystal display device achieves uniform illumination and color integrity at wide viewing angles by creating collimated, uniform light in a backlight assembly before the light reaches an IR filter having a sharp cutoff between near IR and red, and thereafter diffusing the light which is emitted from the filter to create the desired wide viewing angle.
