Personal display device for projecting virtual images to wearer
A recently granted patent (Publication Number: US11921289B2) discloses a personal display device designed to project virtual images for the wearer. The device includes a frame with temple sections and eye see-through sections, a projection display device, and at least one waveguide stack module to propagate image-bearing light beams. The waveguide stack module includes in-coupling and out-coupling diffractive optics to diffract light beams in angular forms for viewing. Additionally, the device features a waveguide housing, aligners for frame and projector alignment, and various components like processors, vibrators for haptic feedback, ambient light sensors, and blackening materials to enhance display quality.
Furthermore, the personal display device incorporates hinge systems with flex cables, hinge housings, and hinge pins for flexibility and battery connectivity. The device also includes touchpad functionality for user interaction, alignment mechanisms for projector mounting frames, and waveguide-frame alignment for optimal display performance. The patent details the construction of the device, including the arrangement of diffractive optics, outer and inner covers for sealing, and specific materials like komoto, carbonfeather, Aktar, or black paints for light absorption. Overall, the patent outlines a comprehensive design for a personal display device that integrates advanced optical technologies and ergonomic features for an enhanced user experience.
