Patent Primary Examiner
A waveguide illuminator includes an input waveguide, a waveguide splitter coupled to the input waveguide, and a waveguide array coupled to the waveguide splitter. The waveguide array includes an array of out-couplers out-coupling portions of the split light beam to form an array of out-coupled beam portions for illuminating a display panel. Locations of the array of out-couplers are coordinated with locations of individual pixels of the display panel, causing each light beam portion to propagate through a corresponding pixel of the display panel, thereby improving efficiency of light utilization by the display panel.
