Patent number: 9778461Abstract: A head-up display device is for projecting display light onto a projection member. The head-up display device includes a display, a reflecting member, an outside light prevention portion, and a state controller. The display emits the display light. The reflecting member reflects the display light emitted from the display in a reflection direction to project the display light onto the projection member. The outside light prevention portion changes between an entering state in which outside light is able to enter the display and a preventing state in which outside light is prevented from entering the display. The state controller controls the outside light prevention portion to be (i) in the entering state when the display light is projected onto the projection member and (ii) in the preventing state when the display light is not projected onto the projection member.Type: GrantFiled: April 29, 2015Date of Patent: October 3, 2017Assignee: DENSO CORPORATIONInventors: Makoto Sakai, Hiroshi Ando

Patent number: 9766452Abstract: A vehicle head-up display device includes a stepping motor that outputs a rotation to adjust an optical position of a reflecting mirror, a zero detection unit that detects a zero position by the rotation of the stepping motor in a return-to-zero direction, an initial adjustment unit that adjusts the optical position to an initial position based on the zero position by the rotation of the stepping motor in an away-from-zero direction, and a user adjustment unit that, after the adjustment of the initial position, adjusts the optical position to a command position based on the zero position responsive to a command from the vehicle user. The zero detection unit sets a higher rotation speed of the stepping motor than the user adjustment unit, and sets a lower output torque than the user adjustment unit.Type: GrantFiled: September 2, 2014Date of Patent: September 19, 2017Assignee: DENSO CORPORATIONInventor: Tatsuya Sasaki

Patent number: 9726896Abstract: Methods, apparatus, and computer-readable media are described herein related to a virtual monitor display technique for augmented reality environments targeted at allowing a user of a display-enabled computing device to substitute their conventional hardware-realized display screen with a virtualized display screen of equal or better usability characteristics than the hardware-realized device. A virtual screen is rendered via a micro display in an augmented reality environment to a human user wearing a see through head mountable device. The system architecture makes use of liquid lens technology in order to adjust the relative position of the display as well as the focal distance by optical means only thereby ensuring that the virtual screen is rendered at the maximum resolution of the micro display at all times. The system architecture also comprises an occlusion matrix thereby ensuring that the virtual screen is free of ghosting.Type: GrantFiled: April 21, 2016Date of Patent: August 8, 2017Inventor: Maximilian Ralph Peter von und zu Liechtenstein

Patent number: 9703101Abstract: A see-through head or helmet mounted display device (10) comprises a see-through member (18) having a see-through area (22). The see-through member (18) includes a plurality of display segments (20; 20a, 20b) for emitting visible light. The plurality of display segments (20; 20a, 20b) is provided within the see-through area (22) in a mutually spaced manner such that the see-through area (22) includes a see-through zone (24) between each pair of adjacent display segments (20; 20a, 20b). The see-through zone (24) allows visible light to pass through the see-through member (18). The see-through member (18) further includes a plurality of holographic optical elements (26; 26a, 26b) provided within the see-through area (22). Each holographic optical element (26; 26a, 26b) is associated with a respective display segment (20; 20a, 20b).Type: GrantFiled: October 23, 2012Date of Patent: July 11, 2017Assignee: Lusospace, Projectos Engenharia LDAInventors: Ivo Yves de Matos Peteira Vieira, Paulo Romeu Seabra Gordo, Alexandre Pereira Cabral, Manuel Adler Sanchez de Abreu

Method for manufacturing light guide device, light guide device, and virtual image display apparatus
Patent number: 9557567Abstract: During the manufacturing of the light guide device (20), the first and second bonding ribs (R1,R2) are used such that the light guide prism (10) and the opposing prism (50) are connected with each other from a specific offset direction. In this case, a difference between sizes of clearances between the first bonding surface (AS) and the second bonding surface (BS) caused by a difference in inclination angles of the offset direction with respect to the first bonding surface is used such that a flow direction of the adhesive is controlled and filling is performed in a desire state, and thus high accuracy of the joint formed by the adhesive is maintained.Type: GrantFiled: February 5, 2014Date of Patent: January 31, 2017Assignee: SEIKO EPSON CORPORATIONInventor: Noriaki Hiraide
