Abstract: A display device includes a diffusion layer providing a single well, an optical element configured to receive light and output the received image light including a concentric series of lens segments made up of active facets, and a waveguide having an in-coupling grating and a waveguide body optically coupled to the image light, where a polarizing component is disposed over an output surface of the optical element. A method to improve a yield of silicon backplane displays includes connecting a diode having a resolution to a backplane and repairing a defect on a pixel display area by dividing the pixel display area into at least one subcircuit, while improving geometry stylization transfer for 3D models of real-world environments. A method for suppressing crosstalk for user conversations includes receiving multiple speech signals captured by multiple microphones and generating directional data for the multiple speech signals based on spatial filtering.

Abstract: An optical assembly to reduce glare and enhance sharpness in a head-mounted device (HMD) is provided. The optical assembly may include an optical stack, such as pancake optics. The optical assembly may also include at least two optical elements. The optical assembly may further include at least one liquid crystal (LC) layer between the at least two optical elements, wherein the liquid crystal (LC) layer provides dynamic glare reduction and enhanced sharpness using a controllable polarization technique. In some examples, the controllable polarization technique may include determining optical assembly orientation using a sensor. Based the optical assembly orientation, the polarization of the at least one liquid crystal (LC) layer may be dynamically adjusted via adjustments in applied voltage to minimize or reduce glare and enhance visual sharpness.
