    摘要: A display device includes an image display device that includes an image display surface that emits light polarized in one direction and displays an image; and a superimposing display device that includes a transparent light guide plate that is provided overlapping the image display surface, transmits the light emitted from the image display device, and also has grooves constituting a pattern formed thereon, includes a light source that irradiates an end surface of the transparent light guide plate with light, and is switched between display and non-display of the pattern based on lighting and non-lighting of the light source. A polarization direction of the image display device and an extending direction of the grooves intersect at an angle range of 75° to 105°. Accordingly, the display device can ensure proper visibility.

    摘要: Provided is a vehicular display device that offers good visibility without causing a passenger to feel uncomfortable. In a bezel that includes a cover portion arranged above a display unit of a vehicular display device and a frame portion enclosing the cover portion, a front-side end portion of the cover portion is arranged at a position lower than a rear-side end portion. As a result, external light is reflected forward. Moreover, a front frame includes a reflecting plate, a semi-transparent output plate covering over the reflecting plate, and a light-collecting portion collecting external light that enters from a front into a space enclosed by the reflecting plate and the output plate. As a result, the front frame is prevented from being darkly reflected onto a front glass.

    摘要: An indicator device for vehicles has an information indicator panel, and a cover provided in front of the panel. The cover comprises a base layer, a polarizing layer, an anti-glare layer and an anti-reflection layer. The cover is arranged so that P-polarized light from the polarizing layer becomes incident to a front windshield in an angle of about 56null. Thus, the reflectance of the P-polarized light is reduced to about zero, and the light emitted from the panel is restricted from forming a virtual image by reflection on the front windshield.

    摘要: One subject of the invention is a light guide (13), for an interface module, in particular for a vehicle passenger compartment, for emitting or receiving a light beam in a cone that is elongate in a transverse direction and that is centred on a plane that is inclined by an angle θ with respect to an optical axis (z) of the light guide, taking the form of a prism made of transparent material of index nGL, characterised in that it comprises: •an interior dioptric interface intended to face a printed circuit board (7) bearing a light source (5) or a light detector, forming a convergent lens the focal point of which is located at an expected position of the light source (5) or of the light detector, •a first planar face (15) that is oriented parallel to the optical axis (z) of the light guide, and •a second planar face (17) that is inclined with respect to the first face (15) by an angle α respecting cos(α+θ)=(1−ε) nGL*cos 3α, with ε a number comprised between −0.1 and 0.1.
