LED night vision imaging system lens and backlight assembly

摘要

A light emitting diode (LED) night vision imaging system (NVIS) lens apparatus for use in filtering of a plurality of night-mode LEDs is provided. The lens apparatus includes an optical carrier material having a plurality of apertures disposed and arranged such that, when the lens apparatus is coupled to an LED backlight, each of the plurality of apertures allows light from a corresponding day-mode LED to be transmitted therethrough without filtering. The lens apparatus also includes filter material coupled to and supported by the optical carrier material. The filter material is disposed and arranged on the optical carrier material such that, when the lens apparatus is coupled to the LED backlight, light from each of a plurality of night-mode LEDs is filtered by the filter material. Backlight assemblies and displays are also provided.
