Abstract
Disclosed herein is a waveguide stack and associated segmented illumination display. The waveguide stack includes a number of waveguides stacked into an array to direct light from light emitting diode (LED) edge lights to a liquid crystal display (LCD) of a segmented illumination display. The waveguides are stacked with light inhibiting material between the waveguides to inhibit light transmitting through one waveguide from communicating to a second waveguide.
