A head up display for a vehicle according to an embodiment includes a display panel configured to emit an image light; a polarized light plate configured to make the image light emitted from the display linearly polarized; a reflective mirror configured to reflect the image light onto a windshield of a vehicle; a polarized light reflective mirror configured to be disposed to face the reflective mirror; and a phase delay mirror configured to convert a phase of the light inputted from the polarized light plate and reflect the converted phase to the polarized light reflective mirror, and to convert a phase of the light reflected from the polarized light reflective mirror and reflect the converted phase to the polarized light reflective mirror, thereby minimizing a width in the forward and backward direction.

A steering device adapted to be rotated about a steering central axis for maneuvering a vehicle, the steering device including a central portion disposed in a vicinity of the steering central axis, and a rim connected with the central portion. The rim includes left and right grip portions that are respectively disposed in left and right regions of the rim apart from the steering central axis, a grip sensor disposed in each of the left and right grip portions, and four luminous portions each of which is configured to be lit under control of a control unit for prompting the driver to grip the grip portions. The four luminous portions are respectively disposed in a vicinity of a first end of and in a vicinity of a second end of each of the left and right grip portions, in an area out of the left and right grip portions.

A dial plate being nonopaque is in a disc shape. A slit member has slits each extending through the slit member in a thickness direction. A light source is located on an opposite side of the slit member from the dial plate. The light source is configured to emit light through the slits of the slit member toward the dial plate to project images on the dial plate.

The embodiments disclosed in this application describe a displaying system, a displaying method, and a head-up display. The displaying system includes a display window including a transflective film, an image source for emitting s-polarized light incident on the transflective film, where the transflective film has an average reflectivity more than 50% for the s-polarized light, and where the imaging window is further used to transmit ambient light. The embodiments disclosed herein can reduce the demand on the brightness of the image source, can eliminate ghost image, obtain better visual effect, and reduce cost.

The present invention relates to a separate head-up display device, an adhesive paste set on a bottom side of the base of a display module is provided to adhere on a windshield, to reduce shakes that a reflective sheet of a reflective sheet adjustment module is fixed on the dashboard and the windshield, and rotary joint structures are further set between the display module and the reflective sheet adjustment module, so that a driver may easily adjust the direction of the reflective sheet to obtain an optimal viewing angle, to thereby improve driving safety.

The embodiments disclosed in this application describe a displaying system, a displaying method, and a head-up display. The heads-up displaying system includes a display window including a transflective film, an image source emitting light incident on the imaging window, and the light emitted by the image source before reaching the transflective film only comprising s-polarized light. The transflective film is configured to directly reflect a first portion of the s-polarized light emitted from the image source. The transparent substrate reflects a second portion of the s-polarized light, and transmits a third portion of the s-polarized light to the air, the first portion of the s-polarized light, the second portion of the s-polarized light and the third portion of the s-polarized light are all s-polarized light.

The vehicular display control device is mounted on an autonomous driving vehicle provided with a windshield display. The windshield display is configured to change a transmittance of external light. The vehicular display control device includes a transmittance control unit configured to reduce the transmittance in order to promote a sleep of at least one passenger.

A display device includes a plurality of display units and a reflector. The plurality of display units emits display light representing an image to be displayed from a display screen. The reflector is disposed to face the display screen of each of the plurality of display units and reflects the display light emitted from each of the plurality of display units.

A head up display system is provided and includes an image source, an image adjustment device, a controller, and a reflector. The image source is adapted to output an image with an image light traveling in a light path. The image adjustment device is positioned on the light path of the image light, wherein the image adjustment device comprises a liquid crystal panel. The controller is adapted to control the image adjustment device. The reflector is adapted to reflect the image light passing through the image adjustment device to a projection screen. A display method of a head up display system is also provided in the disclosure.

A heads up display system of a vehicle includes a combiner screen having a first substantially transparent substrate defining a first surface and a second surface, a second substantially transparent substrate defining a third surface and a fourth surface. A primary seal is disposed between the first and second substrates. The seal and the first and second substrates define a cavity therebetween. An electro-optic material is positioned within the cavity and a transflective layer having a multilayer polymeric film positioned on one of the first and second surfaces, and a projector for projecting light having a first polarization toward the first surface of the first substrate.
