A head-up display device includes an illumination optical system, an imaging optical system and a reflective optical system. The illumination optical system emits a source light indicating information. The imaging optical system projects the source light to a projection surface. The reflective optical system has a dielectric multilayer film, and is configured so that a retardation of a subject wavelength including at least a part of wavelengths of the source light from the illumination optical system is in a range greater than /2 [rad] and smaller than /2 [rad]. The reflective optical system is arranged on a path from the illumination optical system to the imaging system so that a polarization axis of the source light from the illumination optical system defines an angle satisfying a relation of 0 degree <<90 degrees <<180 degrees, relative to an incident surface.

A display device for a vehicle including: a first display configured to output first light forming first visual information; a second display configured to output second light forming second visual information; a light synthesizing unit located on an advancing path of each of the first light and the second light and forming a first acute angle with the first display and a second acute angle with the second display and configured to transmit therethrough the first light from the first display and reflect the second light from the second display; a first tiltable reflector; a second tiltable reflector; and a driving unit configured to: tilt the first tiltable reflector to form a first angle with the second display so the first tiltable reflector reflects part of the second light directed toward the light synthesizing unit toward a first direction, and tilt the second tiltable reflector to form a second angle with the first display so the second tiltable reflector reflects part of the first light directed toward the light synthesizing unit toward a second direction different from the first direction.

A vehicle reflective device where the device reflectivity is adjustable by automatic or manual means, the variable reflectance element including a metallic mirror reflector on one side of a substrate. The variable reflectance function is automatically referenced to ambient light levels (day or night) and manually adjusted in response thereto. In an automatic mode, the variable reflectance assembly provides the user immediate eye protection from reflected high intensity glare by effecting near instantaneous adjustment in mirror reflectivity, such that the intensity of the reflected light impinging on the eye is automatically adjusted so as to be at comfortable levels. The mirror construction is one piece, and allows the viewing of a display monitor located behind the mirror, the mirror and monitor being operatively coupled together. In addition, the device houses a microprocessor that supports a number of software applications whose output is displayable on a designated portion of the device, the microprocessor also establishing a reflectance level within a relatively linear value of the ratio of glare light to ambient light to ensure that information displayed on the monitor screen is always available for viewing by the driver.

A method for pairing a key fob with a control unit is provided. The key fob executes an ID authenticated key agreement protocol with a pairing device based on a key fob identification to authenticate one another and to generate a first encryption key. The pairing device encrypts a control unit identification using the first encryption key. The key fob receives the encrypted control unit identification transmitted from the pairing device. The key fob then executes an ID authenticated key agreement protocol with the control unit based on the control unit identification to authenticate one another and to generate a second encryption key. The key fob then receives an operational key transmitted from the control unit that is encrypted with the second encryption key.

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.

A display panel is attached to an appliance that includes first and second light sources, in which one of the first and second light sources is capable of being turned off when the other is turned on. The display panel basically includes a molded body, a front-side decorative layer, and a sheet-like member. The display panel is capable of individually illuminating a plurality of graphics, which is simultaneously molded and decorated, with light passing through a molded resin. In particular, a first graphic is illuminated in a first window by turning on the first light source, while a first back-side light-shielding region and a second front-side light-shielding region prevent a second graphic from being illuminated. The second graphic is illuminated in a second window by turning on the second light source, while a second back-side light-shielding region and a first front-side light-shielding region prevent the first graphic from being illuminated.

An operation input apparatus for a vehicle, comprising: a touch panel display that extends in a vehicle width direction; an instrument panel that has a flat surface that extends from a position near a lower end of the touch panel display, in a rearward direction of the vehicle; and an operation input unit that is provided in the flat surface, wherein the operation input unit includes one or more button switches, and upper surfaces of the one or more button switches are flush with the flat surface, or are located on a lower side of the vehicle relative to the flat surface.

A method, system, and devices for implementing a selectively lighted instrument cluster are disclosed herein. The aspects employ a light house layer (or collection of light house layers) using a combination of light and dark materials to provide individually lit indicia on a cover layer (i.e. applique layer) of an instrument cluster. The combination of light and dark layers selectively applied prevents light leakage into other non-intended portions on the viewable surface of the instrument cluster.

A control method applied in a display device is provided. The display device includes an image generator and a screen. The image generator is directed to output an output image. The screen is directed to operate in a first operation mode or a second operation mode. The screen has a first light-transmittance in the first operation mode and has a second light-transmittance in the second operation mode. The first light-transmittance is different from the second light-transmittance. In response to the screen operating in the first operation mode or the second operation mode, the image generator outputs the output image onto the screen in a light-emitting period and stops outputting the output image onto the screen in a non-light-emitting period after the light-emitting period.

An interface panel or graphical gauge that can host applications from a mobile application platform and display content from the hosted applications on a display of the graphical gauge. The interface panel may include a native operating system supporting an interface application that generates interface graphical output fed by the native operating system to a graphics controller. The interface control system may be configured to support a guest system that generates guest graphical output fed to the graphics controller. The guest graphical output is representative of graphic information generated by the mobile application platform.
