A vehicle includes: a display panel; a backlight unit disposed at a rear part of the display panel to supply light to the backlight unit; a light collector to collect external light and connected to the backlight unit; a light blocking device disposed between the backlight unit and the light collector to pass or block light; and a controller to determine whether an external light use condition is satisfied based on illuminance of the external light, and open the light blocking device so that the external light is transmitted to the backlight unit when the external light use condition is satisfied.

A display system may include a camera configured to capture an image of a calibration reference associated with an automobile, a display, and a controller in communication with the camera and the display. The controller may be configured to selectively adjust a color temperature of the display based on the image of the calibration reference.

A display with local dimming backlight and an active privacy mode. The display may include a backlight source, lenses, a passive diffuser, an active diffuser and a transmissive display. The backlight source may define a two-dimensional matrix of light sources configured to generate an initial light. The lenses may be mounted adjacent to the backlight source, aligned with the light sources, and configured to generate a collimated light. The passive diffuser may be mounted adjacent to the lenses and configured to spatially spread the collimated light. The active diffuser may be mounted adjacent to the passive diffuser, configured to generate an intermediate light in response to the collimated light, and configured to change a diffusive property of the intermediate light in response to a scattering signal. The transmissive display may be mounted adjacent to the active diffuser and configured to generate multiple visible images by modulating the intermediate light.

A backlight unit for a vehicular component is disclosed. In particular, the vehicle component is for displaying vehicular information. The backlight unit comprises a screen divided into an array of segments and a transparent plate for directing light rays through the screen. Each segment of the array of segments is capable to operate between a mode for permitting light rays to pass through, allowing light rays passing through the transparent plate and the screen, and a mode for blocking light rays from passing through blocking light rays from passing through the screen.

A light source device includes a plurality of light sources arranged in a matrix, a substrate, and a reflective member. The reflective member includes first walls defining a first region entirely surrounded by the first walls in a plan view, and second walls located on an outer side of the first walls, the second walls defining a second region and a third region each only partially surrounded by the second walls in the plan view such that an area of the second region is equal to or greater than a half of an area of the first region and an area of the third region is less than the half of the area of the first region in the plan view. The light sources are disposed respectively in the first region and in the second region while none of the light sources is disposed in the third region.

A display device and a vehicle head-up display apparatus of the present disclosure include a substrate, light source devices, a transmission-type display panel, and an illumination optical system. The light source devices are disposed on the substrate. The illumination optical system guides illumination light from the light source devices to the display panel. The illumination optical system includes a first reflector, a quarter-wave plate, and a reflective polarizer. The first reflector is disposed at a different position on the substrate than the light source devices. The quarter-wave plate is disposed between the first reflector and the display panel. The reflective polarizer is disposed between the quarter-wave plate and the display panel.

An operating knob for an operating apparatus extends away from a reference plane that delimits the operating knob on a rear side. The operating knob is in the form of a three-dimensionally protruding body in relation to the reference plane up to a knob height. The operating knob has at least one side wall extending between the reference plane and the knob height at an angle greater than 20 with respect to the reference plane as a placement surface for at least one finger operating the operating knob. Luminous outputs of at least one luminous segment or a pixel matrix are provided on the side wall.

The liquid crystal illumination device includes a light source projecting light to a liquid crystal panel, a first diffusion unit diffusing the projected light, a first light guide unit including a radially widened reflection surface and reflect the diffused light at the reflection surface, a reflecting mirror including an opening, part of the light guided by the first light guide unit being reflected and returned to inside the first light guide unit, and remaining light passing through the opening, a light collecting unit collecting light passing through an opening on the reflecting mirror, and a second diffusion unit diffusing the collected light toward the liquid crystal panel. The opening on the reflecting mirror is formed correspondingly to a display region where the liquid crystal panel display an image. A haze value of the first diffusion unit is set to a value higher than that of the second diffusion unit.

An operating device for a transportation vehicle for operating a function of a transportation vehicle, wherein the operating device includes LEDs arranged adjacent to one another forming a matrix, wherein a processing unit ascertains whether light of at least one first LED is reflected and/or radiated because of an operating action at least into a second LED.
