Disclosed is a system for controlling the visual appearance of a sensor cover on a vehicle. The system includes a processor, and a sensor cover display disposed on the sensor cover and in communication with the processor. A color-changing element is included in the sensor cover display. The processor is configured to provide a signal representing a desired color or pattern to the color-changing element, and the color-changing element is configured to render the desired color or pattern.

A system of the present invention reduces the size and/or increases the efficiency of a display system or device that integrates or includes a display, for example, an LED display such as a microLED display and OLED display or an LCoS display into such system or device. Embodiments of the present disclosure include, but are not limited to, a display wherein the at least two pixels are four pixels comprising two green pixels, one blue pixel, and one red pixel, and wherein a pixel logic circuit maintains the red pixel in an on state while driving the two green pixels and the blue pixel in accordance with a field sequential color (FSC) pixel drive process or method.

A reflective display device includes a layer of pigment material that is divided into a plurality of pixels, the pigment material in each pixel displaying information by reflecting light. The reflective display device further includes a light source embedded in the layer of a pigment material, wherein the light source emits light that is reflected by the pigment material.

Disclosed is a display device for increasing an aperture ratio of a transmissive part. The display device includes data lines overlapping with one or more of the pixels emitting light to display an image. Each pixel includes subpixels arranged within the pixel along a same direction as the data lines. The display device further includes transmissive parts arranged in the first direction and corresponding to adjacent pixels. In addition to the data lines overlapping the pixels, the display device may include power lines and reference voltage lines parallel with the data lines and overlapping with the pixels. The display device may include scan lines and sensing lines arranged to cross the transmissive parts and data lines. As a result, the number of lines crossing the transmissive parts is reduced, thereby increasing an aperture ratio of the transmissive parts.

A vehicular trailer hitching assist system includes a rear backup camera disposed at a rear portion of a vehicle and a control disposed in the vehicle. A display device includes a video display screen operable to display video images for viewing by a driver of the vehicle. Responsive to the driver initiating a hitching maneuver event by engaging reverse gear of the vehicle, rear backup video images derived from image data captured by the rear backup camera are displayed at the video display screen. An overlay overlays the displayed rear backup video images and aids in guiding connection of a trailer hitch of the equipped vehicle to a trailer tongue of a trailer. Continued display of rear backup video images that are overlaid by the overlay is ceased upon elapse of a threshold period of time or upon exceeding a threshold speed or upon exceeding a threshold distance traveled.

A display assembly with dielectric filters is presented herein. The display assembly includes a light source assembly, a dielectric filter array, and a modulation layer. The light source assembly generates laser light in multiple color channels, and each color channel is associated with a different laser emission spectrum. The dielectric filter array includes respective sets of reflective dielectric filters for each color channel. Each set of reflective dielectric filters is matched to the different laser emission spectrum such that reflective dielectric filters in each set transmit light in the different laser emission spectrum and reflect light outside of the different laser emission spectrum. The modulation layer is positioned between a first electrode layer patterned on the dielectric filter array and a second electrode layer. The modulation layer modulates light from the dielectric filter array based on emission instructions applied via the first and second electrode layers to form an image.
