  • Patent number: 11370360
    Abstract: A tangent line, described next, is, in top view, parallel to a straight line extending in a width direction of the display surface in a range in which the attitude can be changed. The tangent line is present on a plane orthogonal to the up-down direction of the automobile, and contacts a center of the final reflective surface. In top view, of an angle formed by a straight line connecting a center of the final reflective surface with a center of the display surface and the tangent line of the final reflective surface, a supplementary angle which is supplementary to an angle that is on a rear side of the automobile and that is on a side where the observer is present is an acute angle of less than 90 degrees.

  • Patent number: 11235706
    Abstract: A display system includes: a display that emits light corresponding to image information; a half mirror that receives the light emitted, reflects, as reflected light, a first component of the light received, and transmits a second component different from the first component; and a first reflecting mirror having a concave surface that receives and reflects the reflected light toward the half mirror. The half mirror includes a first retardation film, a first support substrate, and a reflective polarizing film stacked in this order from a side on which the light emitted is received. The first retardation film changes a phase of the light received. The first support substrate is light-transmissive. The reflective polarizing film reflects a first polarized component and transmits a second polarized component different from the first polarized component.

  • Publication number: 20200377021
    Abstract: A display system includes: a display device; a reflection optical system; a housing; and a shield member. The reflection optical system includes at least a last reflective member on which light, emerging from a display screen of the display device, is incident either directly or indirectly. The shield member is held by the housing to assume either a shielding state or an unshielding state. The shielding state is a state where the shield member at least partially cuts off light incident on, or reflected from, the last reflective member. The unshielding state is a state where the shielding state is canceled. The shield member in the shielding state reflects, toward the viewer's eyes, external light impinging on the housing. The housing has a holding structure to hold the shield member, no matter whether the shield member assumes the shielding state or the unshielding state.
