A window tinting system for vehicles is disclosed. The system includes a tinted glass with adjustable tint levels, controlled automatically or manually. The automatic adjustment is facilitated by a light sensor detecting sunlight intensity and transmitting data to a tint control module, which adjusts the tint level for optimal protection. A control knob disposed on the vehicle's dashboard is linked to the tint control module through control circuitry and can be turned to manually adjust tint. Additionally, a mobile application enables remote control of the tint level. The tinted glass features an outer photochromic layer that darkens in response to UV light and an inner electrochromic layer controlled by the tint control module.

The present application discloses a display panel and an onboard display apparatus. The display panel comprises a first electrode layer; an emissive layer group provided on the first electrode layer; a light extraction layer provided on the emissive layer group, the light extraction layer being in a light emission direction of the display panel and serving as a second electrode layer; and an encapsulation layer provided on the light extraction layer; wherein a refractive index of the light extraction layer is smaller than that of the encapsulation layer, so that the anti-reflection of light emitted by the emissive layer group is realized. In the display panel, the light extraction layer and the encapsulation layer form an anti-reflection layer, so that light emitted by the emissive layer group is emitted as much as possible, and the brightness of the display panel is improved.

A HUD 10 is configured to be able to display a plurality of virtual images at different distances. The HUD 10 includes an image generation unit 12 and a shielding member 14. The image generation unit 12 generates a first image for forming a first virtual image and a second image for forming a second virtual image to be displayed nearer than the first virtual image. The shielding member 14 can reduce an amount of external light incident on the image generation unit 12. The shielding member 14 is movable between a position through which first light constituting the first image emitted from the image generation unit 12 passes and a position through which the first light does not pass.

Disclosed is a display device including a display panel including a display area and a non-display area surrounding the display area; a back plate disposed on one face of the display panel and including a first ground path unit; and a heat-dissipation plate disposed on a back face of the back plate and including a second ground path unit, wherein the first ground path unit covers at least each of corners of the back plate, wherein the second ground path unit vertically overlap the first ground path unit.

A display device for a vehicle includes: a display, a polarization switching unit, a reflector, and a controller. The polarization switching unit includes a wave plate that can cause emission light of the display to be emitted while changing a polarization direction thereof, and a drive device that can rotate the wave plate between a position of not using polarizing sunglasses and a position of using polarizing sunglasses. The controller rotates the wave plate within a prescribed range, detects luminance values for each fixed rotation angle of the wave plate within a prescribed range from imaging information of an imaging device that transmits a principal component of transmitted light of the wave plate at a position of the eye box, and sets, as a correction angle, a rotation angle of the wave plate corresponding to a maximum luminance value among the luminance values.

A device for minimizing the effects of glare of a driver of a vehicle is proposed. The device comprises a circuit configured to determine a glare intensity of the glare of the driver of the vehicle. The circuit is further configured to activate an in-vehicle safety function to increase driving safety in the presence of glare if the glare intensity exceeds a threshold.

A method for displaying a rearward image of a vehicle includes varying reflectivity of an electro-optic layer for incident light to transmit a portion of the incident light and to reflect another portion of the incident light; displaying on a display at least the portion of the rearward image; and switching the electro-optic layer between a first posture and a second posture. When the electro-optic layer is in the first posture, at least the portion of the rearward image is displayed, and when in the second posture, the reflectivity of the electro-optic layer for the incident light varies between at least two values based on at least one of a first illuminance or a second illuminance. The first illuminance indicates brightness around the vehicle and the second illuminance indicates intensity of light emitted on a front surface of the electro-optic layer.

A vehicle display device includes: a housing mounted on a vehicle and having an opening facing a windshield; an image display device that is disposed inside the housing and outputs display light of an image; a mirror that is disposed inside the housing, faces the windshield through the opening, and reflects the display light toward the windshield; a cover that is transparent, disposed at the opening and having a free-form surface formed to have an optical function; and a suppression means that is disposed at an edge of the cover and suppresses reflection of light on an end surface of the cover.
