| titleOfInvention | A near-eye display device based on polarized contact lenses |
| abstract | The invention discloses a near-eye display device based on a polarizing contact lens, which includes: a micro-projector for projecting images; a waveguide for folding an optical path, with at least two diffraction gratings or reflective layers on its surface or inside for light Incoupling, outcoupling, and exit pupil expansion; polarizers, used to filter light, only allow light with a specific polarization direction to pass through; polarization rotators, used to change the polarization direction of light; polarized contact lenses, used for light filtering and Vision correction only allows light in a specific polarization direction to pass through, and its diopter depends on the wearer's vision; the near-eye display device can be a monocular display or a binocular display. The near-eye display device can realize super-large viewing angle, shielding of real objects by virtual objects, and vision correction functions, and is suitable for head-mounted display devices and smart wearable devices, such as smart glasses. |
