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.

Described herein are deadfront assemblies that are configured to exhibit variable transmission and reflection performance attributes. The deadfront assemblies described herein comprise a first ink layer, an intermediate layer, and a second ink layer. The intermediate layer is disposed between the first and second ink layers and is configured to reflect light that is transmitted through the first ink layer back through the first ink layer so that one or more colors of the ink in the first ink layer is visible in the reflected light. The second ink layer is configured to counteract deviations in optical transmission caused by the first ink layer so that light transmitted through the deadfront assembly is not perceptively altered in color. Overlapping regions of the first and second ink layers comprise inverse appearance attributes so that light output from a light source and transmitted through the deadfront assembly has a desired appearance.

A sound output and text display device for a vehicle, including: an output unit that, in a case in which sound to be output inside the vehicle has been decided, outputs the sound inside the vehicle; and a display unit that displays text corresponding to the sound on a windshield in accordance with a state of use of the vehicle.

A rotary dial assembly includes a rotary dial configured to selectively display a plurality of graphical images and a polarized film assembly disposed in the rotary dial and configured to control the selective displaying of the plurality of graphical images on the rotary dial. When the rotary dial is rotated the polarized film assembly is illuminated such that at least one of the plurality of graphical images is displayed on the rotary dial assembly.

An automotive vehicle includes a cabin, a controller, and a multi-view display. The multi-view display has a first side facing the cabin and a second side facing the exterior of the vehicle. The multi-view display has a first-side display screen, a second-side display screen, and a blocking layer disposed between the first-side display screen and the second-side display screen. The first-side display screen and the second-side display screen are in communication with the controller and operable to display a first pattern on the first-side display screen and a second pattern, distinct from the first pattern, on the second-side display screen.

An aerial display device is mounted on a vehicle and displays information toward a driver seated in a driver seat of the vehicle. The aerial display device includes a display panel and a reflector array. The display panel including a display surface that emits images as light, the display panel being orientated such that the display surface faces toward the driver seat, the display surface including a screen display area and an aerial display area located next to the screen display area. The aerial display area is located at the upper edge portion of the display surface in an installed orientation. The screen display area is a part of the display surface located below the aerial display area. The reflector array forms the light emitted from the aerial display area as an aerial display image in midair above to the aerial display area.

The present invention relates to a lens system for a head-up display. The technical gist of the present invention is to provide a lens system for a head-up display, comprising: a first group of lenses positioned toward a screen with reference to a diaphragm; and a second group of lenses positioned toward an image element, wherein each lens is combined/arranged such that the DN/DT (abs.) (temperature coefficients of refractive index (10.sup.6/ C. at 632.8 nm)) value of a lens that satisfies |P|>=40 (P is refractive power of each lens), among the plurality of lenses constituting the first and second groups of lenses, has a positive number value or a negative number value according to the refractive power, and the lens system accordingly has thermal compensation characteristics by controlling the amount of change in the focal distance of each lens. Accordingly, the present invention advantageously provides a lens system for a head-up display wherein the DN/DT value, which follows the refractive power of each lens, is arranged/designed appropriately such that temperature-based thermal compensation characteristics are satisfied by controlling the amount of change in the focal distance of each lens.

A display unit for a vehicle includes an electronic display and a light guide coupled to a portion of the display.

A vehicle controller determines likelihood of downshifting, such as by detecting braking and clutch disengagement. In response, the vehicle controller determines a desired angular velocity for the engine for a gear lower than a current gear. A tachometer display is updated to indicate the current angular velocity of the engine and the desired angular velocity. A difference between current and desired angular velocities is determined and fill in a region of the tachometer display, such as a sector between needles indicating current and desired angular velocities or most or all of a surface of the tachometer. The tachometer may be updated in the same manner according to a desired angular velocity in cases where the drive shifts into gear following coasting in neutral.

A display device for installation in a vehicle can include a first display configured to output first light forming first visual information; and a light synthesizing unit configured to pass the first light through the light synthesizing unit, and reflect second light and third light generated by different light sources, in which the light synthesizing unit includes a first light synthesizing portion disposed with a first surface of the first light synthesizing portion facing a first direction, and the first light synthesizing portion is configured to pass the first light through the first light synthesizing portion and reflect the second light; and a second light synthesizing portion disposed with a second surface of the second light synthesizing portion facing a second direction different from the first direction, and the second light synthesizing portion is configured to pass the first light through the second light synthesizing portion and reflect the third light.
