Publication number: 20220078373Abstract: An optical imaging system including an elongated lightguide having pluralities of first and second light extractors forming respective first and second patterns along the length of the lightguide is described. Light extracted by the first light extractors exit the lightguide primarily along a first direction toward a target location, and light extracted by the second light extractors exit the lightguide primarily along a second direction different from the first direction. The optical imaging system includes a first reflector for receiving light exiting the lightguide primarily along the second direction and reflecting the received light toward the target location. The first reflector forms a first virtual image of the second pattern behind the first reflector. The first pattern and the first virtual image are visible to a viewer viewing the optical imaging system from the target location.Type: ApplicationFiled: November 18, 2021Publication date: March 10, 2022Inventors: Tao Liu, Brent A.

Patent number: 11125929Abstract: A display system including a lightguide and first and second reflective layers disposed on opposite sides of the lightguide is provided. The lightguide has opposing first and second major surfaces and includes a light extraction pattern for extracting light that would otherwise be confined and propagate within the lightguide primarily by total internal reflection. Light extracted by the light extraction pattern exits the lightguide through at least one of the first and second major surfaces of the lightguide. Each of the first and second reflective layers has an average specular reflectance of at least 50% in a predetermined wavelength range. The light extraction pattern may be repeatedly imaged by the first and second reflective layers to produce three-dimensional stacked images of the light extraction pattern.Type: GrantFiled: January 8, 2018Date of Patent: September 21, 2021Assignee: 3M Innovative Properties CompanyInventors: Tao Liu, Brian W.

Patent number: 10634837Abstract: Lightguides that include a plurality of discrete spaced apart light extracting structures are described. Each light extracting structure includes opposing inclined first and second sidewalls extending from a first side of the lightguide toward an optical axis of the light guide and meeting at an elongated peak extending along a first direction substantially perpendicular to the optical axis, and may include opposing first and second endwalls extending between the first and second sidewalls from the first side of the lightguide to the elongated peak to form a notch extending into a core of the lightguide. The first and second sidewalls are adapted to extract light propagating along the lightguide from an opposite second side of the lightguide by reflecting the propagating light toward the second side. The notch may have raised edges along at least a portion of a perimeter of the notch.Type: GrantFiled: April 28, 2016Date of Patent: April 28, 2020Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Tao Liu, Brent A.
