Abstract
Examples disclosed herein include an augmented reality (AR) see-through display system, which includes a diffractive backlight substrate including diffractive gratings. The display system includes a light source to transmit light into the backlight substrate, wherein the diffractive gratings scatter the light out of the backlight substrate to form an array of directional pixels. The display system includes an LCD panel to modulate the array of directional pixels to form an image that augments a real world view visible through the backlight substrate and the LCD panel.
