A liquid crystal projection layer for use in a glass, the glass including a first glass which includes a first surface and a second surface opposite to each other, the liquid crystal projection layer includes a transparent projection layer disposed on a side of the first glass close to the second surface and configured to display a projected image received from a projector; and a liquid crystal module disposed between the first glass and the transparent projection layer and configured to be switchable between a transparent mode and a privacy mode, wherein in the transparent mode, the liquid crystal module allows the projected image displayed on the transparent projection layer to be transmitted towards the first glass, and in the privacy mode, the liquid crystal module prevents the projected image displayed on the transparent projection layer from being transmitted towards the first glass.

A camera monitoring system for a side region of a vehicle, includes an image-capturing unit for simultaneously capturing image data relating to a first ground region and relating to a second ground region on at least one side of the vehicle, and an image-analyzing unit, which is designed to separate image data relating to the first ground region from image data relating to the second ground region so as to enable independent display.

The present disclosure relates to a photovoltaically active laminate that includes a cover film, a photovoltaic active solar cell film, and a fiber composite support layer. The cover film defines a top surface of the laminate and is transparent to incident light radiation. The photovoltaic active solar cell film includes a support film and a coating of a photovoltaically active material applied to the support film. The cover film has a thickness in a range up to 1 mm. The solar cell film has a thickness in a range between 0.06 mm and 2 mm. The support layer has a thickness in a range between 0.8 mm and 3 mm.

A display of roadside objects on a vehicle windshield within a primary field of view of a driver, with an indication of a level of importance of the object is provided. A method includes: detecting, by a computer device, a roadside object in a vehicle driver's peripheral view; analyzing, by the computer device, the detected roadside object to assign a level of importance to the object based on predefined levels of importance; and displaying, by the computer device, the roadside object as a semi-transparent object in a display area of a windshield of the vehicle with an indication of the level of importance of the object.

Reflections from a display device are controlled using retarders arranged on the output side of a display panel which outputs light with a predetermined polarization state. First and second planes of incidence are defined in respect of first and second rays of light output from the device and first and second normals to first and second surfaces of optically transmissive material at first and second points at which the first and second rays of light are reflected. The retarders are selected to cause the polarization state of the first ray to be linearly polarized in a direction that is in the first plane of incidence, and to cause the polarization state of the second ray to be linearly polarized in a direction that is in the second plane of incidence. The reflections from the surfaces are minimized because for both surfaces the polarization direction is in-plane.

A head-up display apparatus prevents a driver from being confused when, for example, the number of overlaid images for alerting or emphasizing that are overlaid on an object increases due to the cutting-in of another vehicle, resulting in overlap between the overlaid images or between an overlaid image and another object resulting in an unclear correspondence relationship between the overlaid images and objects. A display control unit has: an overlap determination unit that, if a first overlay image is overlaid on a first object and a second object as a cut-in object is detected, determines the presence or absence of overlap between the overlaid images or the like; and a visibility control unit that, if the overlap occurs, makes the visibility of the first overlay image overlaid on the first object lower than the visibility of the second overlay image overlaid on the second object.

A method of displaying a three-dimensional (3D) object includes acquiring a driving image from a single camera, classifying line marks including a road surface into one or more groups based on a change in a curvature of a line of the road surface, estimating a pitch angle corresponding to an angle of inclination between the road surface and the single camera for each of the one or more groups, generating 3D information of the road surface, and displaying an 3D object visually overlaid on the road surface based on the 3D information of the road surface.

To clear the line-of-sight (LOS) on a window in a lidar system within a vehicle, ultrasonic transducers are physically attached to the interior surface of the window to remove debris. When debris is detected at the window, the ultrasonic transducers are directed to vibrate at an ultrasonic frequency thereby generating an ultrasonic wave which causes the debris to bounce off the window. In some scenarios, the ultrasonic transducers vibrate with a particular phase shift to generate a travelling wave that causes the debris to sweep across the window. Additionally, windshield wipers, spray from a nozzle, and/or a hydrophobic or oleophobic coating may be used in combination with the ultrasonic transducers to remove the debris from the window.

Disclosed is a vehicle display system (1) for displaying an image of surroundings of a vehicle. The vehicle display system (1) includes: a display (18a) configured to display an image thereon; a camera (4, 6, 8, 10) mounted on the vehicle and configured to image surroundings of the vehicle; and a display control unit (20) configured to subject an image captured by the camera to mask processing, using a mask image (MR, MF) including a semi-transparent portion (M3, M4, M14, M16) corresponding to a vehicle body, and a portion (M8, M18, M19) corresponding to a window of the vehicle and having a transmittance lower than that of the portion corresponding to the vehicle body, to generate a masked image (D), and cause the masked image to be displayed on the display.
