  • Publication number: 20230419922
    Abstract: A display device includes a housing, a variable reflectance element, a display to display at least a portion of a rearward image, a display device control circuit, and an actuator to switch the variable reflectance element between first and second postures. In the first posture, the display displays the portion of the rearward image. In the second posture, the display displays the rearward image. In the second posture, the reflectivity of the incident light varies between first and second values of a first and a second illuminance, respectively. The first illuminance indicates brightness around a vehicle and is detected by a sensor. The second illuminance indicates intensity of light emitted on a front surface of the display device and is detected by another sensor. When the display displays at least the portion of the rearward image, the display is visible to a driver through the variable reflectance element.

  • Patent number: 11787341
    Abstract: A display device includes a housing with an opening; an electro-optic layer that includes a transmissive-reflective layer and configured to vary reflectivity of incident light; a display provided on the electro-optic layer; a control circuit that controls an operation of the display device; and an actuator that switches the electro-optic layer between first and second postures, wherein the control circuit: controls an operation of the display, generates a trimmed image matching a shape of the opening or a shape of the display, outputs the trimmed image to the display, controls the reflectivity of the electro-optic layer when the electro-optic layer is in the second posture, and does not control the reflectivity of the electro-optic layer when the electro-optic layer is in the first posture, and the display is visible to a driver through the electro-optic layer when the control circuit controls the display to display the trimmed image.

  • Patent number: 11501737
    Abstract: A display system includes an image capture device, a display device, and at least one of a first illuminance sensor and a second illuminance sensor. The image capture device captures an image rearward of the vehicle. The display device is coupled to the image capture device, and receives at least a portion of the rearward image captured by the image capture device. The first illuminance sensor detects brightness around the vehicle, and the second illuminance sensor detects intensity of light emitted onto a front surface of the display device.
