Title (EN) AUGMENTED REALITY SEE-THROUGH DISPLAY
(FR) AFFICHEUR TRANSPARENT À RÉALITÉ AUGMENTÉE
Abstract:
(EN) 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.
(FR) Des exemples de l'invention comprennent un système d'affichage transparent à réalité augmentée (AR), qui comprend un substrat de rétroéclairage à diffraction comprenant des réseaux de diffraction. Le système d'affichage comprend une source lumineuse pour émettre de la lumière dans le substrat de rétroéclairage, les réseaux de diffraction diffusant la lumière hors du substrat de rétroéclairage pour former une matrice de pixels directionnels. Le système d'affichage comprend un panneau LCD pour moduler la matrice de pixels directionnels afin de former une image qui augmente une vue du monde réel visible à travers le substrat de rétroéclairage et le panneau LCD.
