Patent number: 11520143Abstract: A display device for a vehicle includes: a first display device including a reflection type hologram that is disposed on a windshield of a vehicle, and a first projection part that projects first display light toward the hologram, and displaying a first display image by diffraction light diffracted by the hologram; and a second display device including a second projection part that projects second display light toward the windshield, and displaying a second display image by reflection light reflected by the windshield. In the windshield, a first region where the first display light is incident and a second region where the second display light is incident overlap with each other, the second projection part includes a filter part that cuts light in a predetermined wavelength region from the second display light, and the predetermined wavelength region is a wavelength region of the light diffracted by the hologram.Type: GrantFiled: September 2, 2020Date of Patent: December 6, 2022Assignee: YAZAKI CORPORATIONInventors: Takuma Ogisu, Kunimitsu Aoki

Patent number: 11491873Abstract: A projection display device includes a display device, an optical system, and a shielding plate. The optical system includes a first mirror and a second mirror provided on the regular optical path, the second mirrors being to provide an optical path convergence point on the regular optical path, and the first mirrors being provided at a position corresponding to the optical path convergence point. The projection display device is configured such that a position of a mirror surface of the first mirror and the second mirror is adjustable in accordance with a position of an eye point of a user so as to project the light toward the projection position that corresponds to the position of the eye point. The shielding plate is provided such that the shieling plate does not interfere with the regular optical path and such that the shielding plate interferes with the different optical path.Type: GrantFiled: July 10, 2020Date of Patent: November 8, 2022Assignee: YAZAKI CORPORATIONInventors: Junichi Ichikawa, Takuma Ogisu, Tetsuya Sugiyama

Patent number: 11467402Abstract: A vehicular display device includes a reflection-type hologram disposed inside a windshield of a vehicle and a projection device that projects display light toward the hologram. The hologram outputs the display light from the projection device as diffracted light that travels toward the eye range of the vehicle. The projection device is arranged such that display light reflected off the windshield travels in a direction different, from the direction toward the eye range in a vehicle width direction.Type: GrantFiled: September 2, 2020Date of Patent: October 11, 2022Assignee: YAZAKI CORPORATIONInventors: Takuma Ogisu, Kunimitsu Aoki, Yoshiyuki Furuya

Patent number: 11428934Abstract: A vehicle display device includes a reflection-type hologram disposed inside a windshield of a vehicle, and a projection device including an image display device outputting a display light and a regulating unit configured to regulate a diffusion angle of the display light, and to project the display light having passed through the regulating unit onto the hologram. The hologram outputs the display light projected from the projection device as diffracted light directed to an eye range of the vehicle, and the regulating unit is configured to regulate the diffusion angle of the display light to an upper limit angle or less such that the display light reflected from the windshield is directed in a direction different from the eye range.Type: GrantFiled: September 2, 2020Date of Patent: August 30, 2022Assignee: YAZAKI CORPORATIONInventors: Takuma Ogisu, Kunimitsu Aoki

Publication number: 20210072537Abstract: A vehicular display device includes: a reflection-type hologram disposed inside a windshield of a vehicle and including a first surface facing a side of an eye range of the vehicle; and a projection device that projects display light of a P wave toward the first surface. The hologram outputs the display light, which is incident on the first surface from the projection device, as diffracted light directed to the eye range, and has diffraction characteristics of condensing the diffracted light in the eye range. The projection device is disposed such that a part of the display light is reflected toward the eye range when an incident angle of the display light on the windshield is within a predetermined angle range.Type: ApplicationFiled: September 2, 2020Publication date: March 11, 2021Inventors: Takuma Ogisu, Kunimitsu Aoki

Publication number: 20190250404Abstract: A head-up display device displays information to a driver in a form of a virtual image by projecting display light onto a reflection member. The head-up display device includes a display device which displays a virtual image of a first display image in a first display plane by emitting display light including the first display image and which displays virtual images of a plurality of second display images in a plurality of second display planes by emitting display light beams including the plurality of second display images, respectively. The first display plane is substantially perpendicular to a reference plane. The second display planes are substantially perpendicular to the reference plane and are arranged in a front-rear direction of the driver in a layered manner, and in which the virtual images of the plurality of second display images are displayed so as to be arranged along the reference plane.Type: ApplicationFiled: April 24, 2019Publication date: August 15, 2019Inventors: Tetsuya Sugiyama, Takuma Ogisu
