Patent Primary Examiner
A waveguide illuminator for illuminating a display panel 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. The out-coupled beam portions undergo optical interference and form a Talbot pattern of illumination correlated with pixel array of the display panel, enabling an optical throughput increase by centering individual Talbot peaks on the display panel pixels.
