AUGMENTED REALITY DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18097870 titled 'AUGMENTED REALITY DISPLAY DEVICE
Simplified Explanation
The abstract describes an augmented reality (AR) display device that uses an optical engine and a light guide plate to display virtual images. The device includes a pupil expansion grating in the second region of the light guide plate to duplicate the light of the virtual image into multiple beamlets. In the third region, an output grating array is formed with small diffractive grating regions arranged at intervals equal to or less than the size of a pupil.
- The AR display device uses an optical engine and a light guide plate to display virtual images.
- A pupil expansion grating is formed in the second region of the light guide plate to duplicate the light of the virtual image into multiple beamlets.
- An output grating array is formed in the third region of the light guide plate with small diffractive grating regions arranged at intervals equal to or less than the size of a pupil.
- The diameter of each small diffractive grating region is equal to or less than the size of the pupil.
Potential applications of this technology:
- Augmented reality (AR) headsets or glasses
- Virtual reality (VR) headsets with AR capabilities
- Medical imaging and visualization
- Gaming and entertainment
Problems solved by this technology:
- Enhances the display quality and resolution of virtual images
- Improves the field of view and image brightness in AR devices
- Reduces the size and weight of AR display devices
Benefits of this technology:
- Provides a more immersive and realistic AR experience
- Enables clearer and sharper virtual images
- Allows for a wider field of view and better image brightness
- Makes AR devices more compact and lightweight
Original Abstract Submitted
Provided is an augmented reality (AR) display device. The AR display device includes an optical engine configured to output light of a virtual image and a light guide plate including a first region that receives the light of the virtual image, a third region that outputs the light of the virtual image, and a second region that propagates the light of the virtual image input to the first region toward the third region, in which a pupil expansion grating is formed in the second region to duplicate the light of the virtual image incident to the first region into a plurality of beamlets, and in the third region, an output grating array is formed in which a plurality of small diffractive grating regions are arranged at intervals equal to or less than a size of a pupil, in which a diameter of each of the plurality of small diffractive grating regions is equal to or less than the size of the pupil.
