To provide a head-up display that can provide light-shielding portions at a plurality of locations while controlling costs. Provided is a head-up display comprising: a display device that displays images; a plane mirror that reflects display light from the display device; a concave mirror that reflects display light via the plane mirror; a cover glass that allows display light to pass through the concave mirror; and a blind cover formed as an integral member, a virtual image being displayed by using the display light projected on an object from the display device via a prescribed optical path through the plane mirror, the concave mirror, and the cover glass, wherein the blind cover is provided with a first light-shielding portion that blocks the display light that deviates from the prescribed light path from the display device to the plane mirror, a second light-shielding portion that suppresses external light passing through the cover glass from entering the inside, and an attachment portion that attaches the plane mirror to the blind cover.

A display device includes a dial, a substrate, a plurality of light source parts, and a transmittance adjustment part. The transmittance adjustment part has a low transmittance part in which a transmittance of light is lower than a predetermined value and a high transmittance part in which a transmittance of light is higher than that of the low transmittance part, and adjusts a transmittance of light from the plurality of light source parts. Each of the light source parts includes a first light source and a second light source having different light-emission colors to be alternately switched on lighting. The low transmittance part is arranged within an area corresponding to the plurality of light source parts. The high transmittance part is located based on a midpoint position where the distance from the adjacent light source parts is equal in the circumferential direction between the light source parts.

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 backlighting arrangement is for a head up display that presents a virtual image to a human driver of a motor vehicle. The arrangement includes a light source emitting light with a non-uniform brightness over a field of view of the human driver. A diffuser includes a surface through which the light emitted by the light source passes. The surface has a texture that varies with position on the surface. The texture scatters the light such that the brightness of the light over a field of view of the human driver is more uniform after passing through the diffuser at a given average brightness than it would be with a diffuser configured to scatter light independent of position after passing through the diffuser.

The information display apparatus has a housing with an opening and a transparent cover formed on the opening, the housing includes image-light generating means configured to generate image light that displays the image information and an optical system configured to allow a driver of the vehicle to recognize image information based on the image light from the image-light generating means as a virtual image in front of the windshield. When S-polarized light on the windshield is assumed to be a first polarized wave while polarized light that orthogonally crosses the S-polarized light in a polarizing direction is assumed to be a second polarized wave, the image-light generating means is configured to generate the image light made of the first polarized wave, and a transmittance/reflectance control means blocks a part of the first polarized wave and the second polarized wave of incident external light entering the housing from the opening.

A vehicle control system comprises an automated driving controler for executing any of a plurality of driving modes which include an automated driving mode for automatically performing at least one of speed control and steering control of a vehicle and a manual driving mode for performing both of the speed control and the steering control based on operation of an occupant of the vehicle, and a visual field condition controller for controlling a front visual field condition of the vehicle based on the driving mode executed by the automated driving controller so as to be either a visible condition or a visual difficulty condition.

The electronic mirror device includes a display and a controller. The display includes a body case, an image display unit, and a light control filter, and is mounted on an installation position of a rear-view mirror in an interior of a vehicle for displaying an image captured by a camera mounted to the vehicle. The body case has an opening, and the image display unit is mounted to the opening of the body case. The light control filter is disposed to face a display surface of the image display unit. The light control filter can switch between at least two modes including a light reflecting mode and a light transmitting mode based on supply of electricity. The controller controls the image display unit and the light control filter.

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.

A light guide unit guides a display light toward a projection member. A multilayer film filter unit transmits the display light with an optical multilayer film and shields an external light incident from a projection window. In the XYZ color system, a first wavelength region is between a wavelength having a maximum value of a color matching function Z and a wavelength having a maximum value of a color matching function Y. A second wavelength region is between the wavelength having the maximum value of the color matching function Y and a wavelength having a maximum value of a color matching function X. A minimum transmittance of the multilayer film filter unit to the display light takes a minimum value among transmittances of respective wavelengths in a target wavelength region. The minimum transmittance in the first wavelength region is smaller than that in the second wavelength region.

Provided is a liquid crystal display device. The liquid crystal display device includes a first substrate including a plurality of thin film transistors; a second substrate that overlaps the first substrate and includes a black matrix and a color filter; a touch electrode on the first substrate or second substrate; and an antistatic layer on the first substrate. The antistatic layer comprises In.sub.2O.sub.3, SnO.sub.2, and SiO.sub.2.
