A display control device for controlling a display position of a virtual image displayed and superimposed on a foreground in a vehicle (A), includes: an information acquisition unit for acquiring state information of the vehicle and extracting attitude change information and vibration information of the vehicle from the state information; a position correction unit for correcting a displacement of the display position of the virtual image with respect to the foreground caused by the attitude change of the vehicle, based on the attitude change information; a rough road determination unit for determining whether a road is a rough road, the road on which the vehicle is traveling or scheduled to travel, based on the vibration information; and a correction suppression unit for suppressing a correction control of the display position executed by the position correction unit and continuing to display the virtual image, based on a rough road determination.

The present invention relates to a display device provided in a vehicle, the display device including a first display configured to output first light forming first time information, a second display configured to output second light forming second visual information, and a light synthesizing unit disposed between the first and second displays and configured to transmit one of the first light and the second light and reflect another one so that the first light and the second light are directed to the same path, and wherein the light synthesizing unit is formed tiltable such that a reference angle formed between the light synthesizing unit and the first display varies.

A vehicle display system is disclosed. The system comprises an electro-optic device configured to switch between a mirror state and a light-transmissive state. The electro-optic device comprises a first substrate and a second substrate forming a cavity. The cavity is configured to retain an electro-optic medium that is variably transmissive such that the electro-optic device is operable between substantially clear and darkened states. The system further comprises a substantially transparent display disposed adjacent to the electro-optic device. The electro-optic device is converted to the darkened state when the substantially transparent display is emitting light.

A display assembly including a first display surface in a first plane and a second display surface in a second plane. The second plane overlaps and is vertically offset from the first plane. A control device is mounted over the first display surface and includes the second display surface. The display assembly is configured to simultaneously project images onto both the first display surface and the second display surface.

Provided is a sheet for drawing user's eyes and guiding the line of sight. A visual line guidance sheet is arranged to cover at least a part of a window for a user to look out therethrough, and configured to guide the user's line of sight, by illuminating a partial region on the visual line guidance sheet. The visual line guidance sheet includes an optically transparent substrate layer, a plurality of LED dies, and a wiring pattern. The controller receives from an imager, an image obtained by imaging a region visible by the user through the window, detects an object targeted for visual line guidance, included in the image, and illuminates the LED dies on the visual line guidance sheet, corresponding to a position of the object.

Display device is disclosed herein, and may be implementable in a variety of contexts, including a motor vehicle (for example, the instrument cluster). A semi-transparent plane is essentially placed in between a display and a mechanical element member. This allows a virtual projection of information over the mechanical plane in an on-state, while the mechanical element shows non-indicia during the off state.

When a pulsed waveform is used to transmit power-supply power in a form of a power packet etc., a filter for reducing harmonic components is disposed on a power transmission side. A switch and a control portion for controlling ON/OFF of a function of the filter are provided to turn ON the function of the filter limitedly at each of timings t1 to t2 and t3 to t4 at which the power is transmitted. The harmonic components are reduced from the waveform of the transmission power by the function of the filter. Radiation noise generated by the wire harness is reduced in a high frequency region. The function of the filter is turned OFF at a timing at which digital information is transmitted so that a waveform of the digital information can be prevented from being deformed.

Provided is a vehicle display device capable of providing a user with appropriate information, without being affected by changes in the position of the viewpoint of the user. This vehicle display device is provided with: an image display unit having a display screen capable of displaying images on at least part thereof; an image generating unit which generates images to be displayed by the image display unit; a viewpoint position acquiring unit which acquires a viewpoint position of a user seated on a driver's seat of a vehicle; and a projecting unit which projects the images toward a transparent front windshield of the vehicle in such a way that the images are reflected in the transparent front windshield of the vehicle, thereby allowing the user seated in the driver's seat to visually recognize a virtual image. The image generating unit determines a usage region to be used to display the images, within the display screen of the image display unit, in accordance with the viewpoint position of the user that has been acquired by the viewpoint position acquiring unit.

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.

A vehicle window plate has a maximum value of a variation of a curvature in a vertical direction being 7.6E-6 mm.sup.2 or less at least within a HUD display area. The curvature preferably increases monotonically from a lower side to an upper side at least within the HUD display area.
