Publication number: 20240054964Abstract: Provided is a head-up display apparatus capable of preventing damage due to sunlight and ensuring user convenience. A reflection mirror M1 reflects an image created by a display panel and projects it onto a display region. A solar radiation sensor detects a sunlight intensity when a position of sun exists within a predetermined detection range. A blocking mechanism forms a projected light path of an image between the display region and the display panel when being turned off, and blocks the projected light path of the image and an incident light path of the sunlight which is direction opposite thereto when being turned on. A protection processor controls ON/OFF of the blocking mechanism based on an estimated temperature of the display panel, which is estimated by using a sunlight intensity from the solar radiation sensor, luminance of a light source, and an ambient temperature.Type: ApplicationFiled: October 27, 2023Publication date: February 15, 2024Inventors: Tomoki YAMAMOTO, Toshinori SUGIYAMA, Akio MISAWA, Nobutaka AMADA, Nagayasu TSUTSUMI, Yuji FUJITA, Souta SATO

Patent number: 10871655Abstract: An image display apparatus 100 for a vehicle is provided with: an image display unit 2 that has a light source and a display element and outputs image light; a mirror 3 that reflects the image light output by the image display unit 2 toward a windshield 7; a mirror drive unit 4 that changes the angle and position of the mirror 3; and a control unit 10 that determines amounts of change in the angle and position of the mirror and controls the mirror drive unit 4. The control unit 10 makes determinations of the amount of change for the angle and position of the mirror in association with each other such that the image is visible even if the position of the driver's eyes 8 changes and the display state of the image with respect to the driver does not change.Type: GrantFiled: December 12, 2016Date of Patent: December 22, 2020Assignees: MAXELL, LTD., HITACHI INDUSTRY & CONTROL SOLUTIONS, LTD.Inventors: Yuki Nagano, Souta Sato, Yuji Fujita, Takumi Nakada, Kazuomi Kaneko

Patent number: 10866415Abstract: A head-up display apparatus displays a virtual image suitably overlapped with actual scenery in accordance with a running condition of a vehicle. The head-up display apparatus acquires various kinds of vehicle information which can be detected by a vehicle and the display of the video image is based on the vehicle information. A mirror is configured to reflect the video image formed by the video image display to project onto the windshield. A mirror driver is configured to change an angle of the mirror and a display distance adjusting mechanism is configured to adjust a display distance of the virtual image with respect to the driver. The angle of the mirror is adjusted via the mirror driver based on the vehicle information such that the virtual image can be displayed with respect to the driver to be overlapped with the scenery.Type: GrantFiled: October 20, 2016Date of Patent: December 15, 2020Assignee: MAXELL, LTD.Inventors: Yuki Nagano, Takumi Nakada, Maki Hanada, Akio Misawa, Souta Sato
