METHOD TO IMPROVE DISPLAY EFFICIENCY AND UNIFORMITY OF AR WAVEGUIDE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18143747 titled 'METHOD TO IMPROVE DISPLAY EFFICIENCY AND UNIFORMITY OF AR WAVEGUIDE
Simplified Explanation
- The patent application is about methods of modifying and engineering the effective thickness of an optical device substrate. - The methods involve depositing a material that matches the refractive index of the substrate. - This deposited material alters the thickness distribution of the optical device. - By adjusting the thickness distribution, the path of light passing through the device is controlled. - The purpose of this control is to direct the light to the output coupling grating. - The innovation lies in the ability to modulate the optical path of light by altering the thickness distribution of the substrate.
Original Abstract Submitted
Embodiments of the present disclosure generally relate to methods of modifying and engineering the effective thickness of an optical device substrate. The methods provide for depositing a material that is index-matched to the substrate to alter a thickness distribution of the optical device. By adjusting the thickness distribution, the optical path of light is modulated to direct the light to the output coupling grating.
