Abstract: A display system includes a projector configured to project light beams on a first region of a dual state liquid crystal (LC) panel to form a first image on the first region. The display system includes the dual state LC panel configured to operate in a dual state where the first region reflects the light beams projected by the projector and a second region of the dual state LC panel transmits light beams of a second image. The display system directs light beams of the first image and the second image onto different areas of a retina of an eye of a user of the display system. The display system includes processing circuitry configured to: determine a location of the first region on the dual state LC panel and control the dual state LC panel and the projector based on the gaze direction.

Abstract: Here discloses a 3D sensing apparatus with AI-controlled Ferroelectric Liquid Crystal beam steering for enhanced dot illumination. The illumination unit for a three-dimensional depth-sensing device includes a light source for emitting an illumination light; a diffuser that diffuses the illumination light into diffused illumination light; and a dual-layer Ferroelectric Liquid Crystal unit, positioned immediately after the diffuser, wherein the dual-layer Ferroelectric Liquid Crystal unit includes a first ferroelectric liquid crystal layer and a second ferroelectric liquid crystal layer, wherein the first ferroelectric liquid crystal layer adjusts a direction of the diffused illumination light, and wherein the second ferroelectric liquid crystal layer corrects a polarization change of the illumination light induced by the first ferroelectric liquid crystal layer.

Abstract: Aspects of the disclosure provide a liquid crystal (LC) device, a head mounted display (HMD) system, and a method of tuning the HMD system. The LC device includes a first electrode structure disposed on a first substrate with an elliptical shape. The first electrode structure includes parallel first segments connected by second segments. The LC device includes a plurality of first control electrodes electrically coupled with the first electrode structure. The plurality of first control electrodes is configured to form LC lenses at different positions. Each of the LC lenses at the different positions is formed when electrical signals are applied to a subset of the plurality of first control electrodes that is associated with the respective LC lens. The LC device includes a second electrode structure disposed on a second substrate and at least one second control electrode electrically coupled with the second electrode structure.

Abstract: Herein disclosed is a three-dimensional depth-sensing device and an illumination module for the same. The illumination module for a three-dimensional depth-sensing device comprises: a light source; a diffuser, diffusing light from the light source; a tunable lens, positioned after the diffuser and having at least three statuses; and a control unit, setting the tunable lens to one of the at least three statuses. The at least three statuses of the tunable lens correspond to at least three configurations between a dot light and a flood light.
