  • Publication number: 20240353676
    Abstract: [Problem] To provide a head-up display excellent in visibility. A light transmitting sheet 60 has an emission window portion 63 that has a pair of left and right sides 63L and 63R and a pair of front and rear sides 63Fr and 63Re, and is a region from which the display light is emitted, a light shielding frame portion 64 that is at least partially fixed to a case 52 and is an opaque region, and a check window portion 65 formed along the pair of left and right sides 63L and 63R and the pair of front and rear sides 63Fr and 63Re within the light shielding frame portion 64 and allowing visual recognition of presence or absence of the adhesive disposed between the case 52 and the light transmitting sheet 60. A check window 65L and 65R along the pair of left and right sides 63L and 63R or a check window 65Fr and 65Re along the pair of front and rear sides 63Fr and 63Re is such that the check window along one side has a smaller area than the check window along the other side of the pair.

  • Patent number: 11474351
    Abstract: A head-up display device makes it possible to increase the number of common parts between when mounted in a right-hand-drive car and when mounted in a left-hand-drive car. A head-up display device includes: a first unit which generates display light; and a second unit to which the first unit is attached, and which displays a virtual image by guiding the display light generated by the first unit to a windshield. The first unit is provided with a projector which emits the display light, and a first optical relay which guides the display light from the projector to the second unit along a virtual plane. The second unit is provided with a second optical relay which guides the display light to the windshield such that an irradiation position at which the windshield is irradiated with the display light is shifted in a car width direction crossing the virtual plane.

  • Patent number: 11099383
    Abstract: The present invention provides a head-up display device wherein a light shielding part for preventing a washout phenomenon is prevented from shining. A head-up display according to the present invention, in which a display unit for emitting display light (L) is housed in a case and the upper portion of the display unit is covered by the light shielding part, has strip-shaped protrusion parts formed on the bottom surface of the light shielding part (42). With this constitution, the strip-shaped protrusion parts prevent the scattered light (SL) resulting from the light (L) output from the display unit from illuminating the bottom surface of the anti-washout light shielding part, thereby preventing the bottom surface from being displayed as a virtual image.

  • Patent number: 10416448
    Abstract: A head-up display includes: a display projecting light; a reflection part reflecting the light; a supported part disposed on the end of the reflection part and including a cylindrical shaft; a support, through which the shaft passes, rotatably supporting the supported part; and an elastic member which has a U-shape cross-section and in which a hole is formed in one end section and a spherical-surface protrusion protruding towards the hole is formed in the other end section that passes through the center axis of the hole. With the supported part supported by the support, the distal end of the shaft passes through the hole, the distal end-side inner circumferential edge of the shaft abuts the protrusion, and the inner surface of the one end section and that of the other end section of the elastic member cause the supported part and the support part to press against each other.
