Abstract
A display apparatus including means for detecting user's gaze direction; first light source; second light source; configuration () of reflective elements to split light to create copies of second image; optical waveguides whose outlets are arranged in tiled layout; opacity masks arranged at inlets of waveguides; and processor. Input image is processed to generate first and second images. Processor is configured to: display first and second images; and for optical waveguides, control respective opacity masks to block respective copies of second image or selectively allow portions of respective copies of second image to pass through towards inlets of waveguides. Light from first light source is optically combined with light exiting outlets of waveguides, to produce output image.
