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.
Claims28
A system, comprising:
- a display comprising a plurality of illumination segments arranged in an M×N array, where M and N are greater than 2 and at least one of M or N is greater than 4;
- a plurality of light emitting diode (LED) edge lights;
- a liquid crystal display (LCD) layer;
- and
- a waveguide stack to transmit light from the plurality of LED edge lights to the LCD layer, the waveguide stack comprising:
- a plurality of waveguides arranged in a stack, each of the plurality of waveguides to transmit light from a one of the plurality of LED edge lights to a portion of the LCD layer;
- and
- a plurality of light inhibiting layers interposed between each of the plurality of waveguides in the stack.
5 more elements
An apparatus, comprising:
- a plurality of waveguides arranged in a stack, each of the plurality of waveguides to transmit light to a first surface of the stack;
- and
- a plurality of light inhibiting layers interposed between each of the plurality of waveguides in the stack.
A method comprising:
- stacking a plurality of waveguides into a waveguide stack, each of the plurality of waveguides to transmit light to a first surface of the stack;
- disposing a light inhibiting material between each of the plurality of waveguides.
